Frequently Asked Questions - RLM 4 Kärcher

How to install the perimeter wire?

The perimeter wire must be laid in an uninterrupted loop clockwise. Secure it with garden pegs or bury it up to 10 cm deep. Avoid crossing wires and keep a distance of at least 20 cm from obstacles.

What to do if the screen displays 'No loop signal' (CN007)?

Check the LEDs on the charging station. If the green LED is blinking or off, check the power supply and the integrity of the perimeter wire. Disconnect and reconnect the power adapter. If the wire is damaged, replace it.

How to perform the automatic calibration run?

Place the robot inside the mowing area, at least 1 m to the left and 1 m in front of the charging station, facing the perimeter wire. Press START. The robot will roll over the wire twice to measure the signal, then return to the charging station.

When should the cutting blades be replaced?

Replace the blades if they are worn or warped. The blades can be rotated 180° to double their lifespan. Use only original Kärcher parts.

How to adjust the rain sensor?

Go to 'Settings' > 'Rain sensor' menu. You can enable/disable the sensor, adjust the delay (waiting time after the sensor is dry) and sensitivity (low, medium, high).

What does error code CN002 (Lift sensor) mean?

The lift sensor was triggered because the robot was lifted or encountered an obstacle. Remove the obstacle and place the robot on a flat surface. The message must be acknowledged manually.

How to program mowing slots?

In the 'Programs' > 'Weekly schedule' menu, select each day and set the start and end times, as well as the mowing type (normal or border) and entry points. Confirm by 'Save'.

The battery is not charging: what to do?

Clean the charging contacts on the robot and station. Ensure the robot is properly positioned on the station. Check that the station is powered (yellow LED on). If the problem persists, contact customer service.

Is it possible to mow a secondary area?

Yes, manually carry the robot to the secondary area (delimited by the same wire). Turn it on, go to 'Settings' > 'Mow secondary area', set the mowing time and start.

How to protect the robot in winter?

Fully charge the battery, clean the robot, store it in a dry and frost-free place. For the charging station, unplug it and store it as well, or use the provided winter cover to protect the charging terminal.

2.8 Integrated battery

The battery is installed permanently in the appliance and may not be changed by the user.

NOTE

Fully charge the rechargeable battery before using it for the first time. The rechargeable battery can be charged in any charge status. Interrupting charging does not damage the rechargeable battery.

The rechargeable battery can only be charged after the appliance has been switched on.

The integrated battery is partially charged on delivery. The battery is regularly recharged during normal operation. The appliance returns to the charging station for this. The integrated electronic control unit with a monitoring function terminates the charging procedure when a 100% charge status is reached. The charging process only functions with perfect contact of the charging contacts on the charging station with the contact surfaces of the appliance. The built-in protection circuit prevents the battery from being charged at temperatures above 45°C. This prevents irreparable damage to the battery. If the operating time of the battery is reduced in spite of it being fully charged, have the battery replaced by a new genuine battery. This task should be carried out by a Karcher dealer, technician or service partner. If the battery charge level has dropped below the threshold set by the manufacturer as a result of ageing or excessively long storage, this means it can no longer be recharged. Have the battery and the monitoring electronic control unit checked by a Karcher dealer, technician or service partner, and replace them if necessary. The battery status is shown on the display. Check the battery status after about 3 months in storage. To do so, switch on the appliance and read off the battery status. If the rechargeable battery is now only charged to approx. 30% or less, place the appliance in the charging station and switch it on so the rechargeable battery is charged. If the charging pole was removed to store the charging station (see chapter 11.2 "Storing the charging station", page 59), first install it again in reverse order and connect the charging station to the mains supply again.

If electrolyte has escaped into the appliance: Have the appliance repaired by a Karcher service centre. If the rechargeable battery has been removed from the appliance: If the eyes or hands have come into contact with escaped electrolyte, flush them immediately with water. Immediately consult a doctor.

2.9 Functional description

Moving on the grass surface

The appliance moves freely in a mowing area delimited by a boundary cable. The appliance is oriented by sensors that detect the magnetic field of the boundary cable.

If the appliance encounters an obstacle, it stops and then continues in another direction. If the appliance detects moisture, it automatically returns to the charging station. If the appliance gets into a situation where it cannot operate, this is indicated by a message on the display.

Mowing and charging

The mowing phases alternate constantly with the charging phases. If the charge of the rechargeable battery drops to a specific value (display:

0%) during mowing, the appliance returns to the charging station along the boundary cable.

Pre-set mowing programs are available for mowing, and also include the lawn and edge mowing function. These mowing programs can be changed.

Each time the mowing motor is started, its direction of rotation is changed which doubles the service life of the cutting blades.

3 SAFETY

3.1 Intended use

This appliance is intended solely for use in non-commercial applications. Any other use (as well as unauthorised conversions or add-ons) are regarded as contrary to the intended use and will result in exclusion of the warranty as well as loss of conformity

(CE mark); the manufacturer will

thus decline any responsibility for damage and/or injury suffered by the user or third parties.

The application limits of the appliance are:

Max. area: 500 m² Max. upward/downward slope: 45% (24°) Max. lateral inclined angle: 45% (24°) Temperature:

3.3 Safety and protective devices

WARNING!

Risk of injury

Defective and disabled safety and protective devices can lead to serious injury.

Have any defective safety and protective devices repaired. - Never disable safety and protective devices.

3.3.1 PIN and PUK input

The appliance can only be started by entering a PIN (Personal Identification Number). This prevents the appliance from being switched on by unauthorised persons. The factory setting of the PIN is 0000. The PIN can be changed, see chapter 5.2 "Making the basic settings", page 52.

If the PIN is entered incorrectly 3 times, the PUK (Personal Unlocking Key) must be entered. If this is also entered incorrectly, the user must wait 24 hours until entering it again.

The PIN and PUK input also serves as an anti-theft device:

• Keep the PIN and PUK so that they are inaccessible to unauthorised persons.

3.3.2 Sensors

The appliance is provided with several safety sensors. It does not restart automatically after being switched off by a safety sensor. The error message is shown on the display and must be acknowledged. The reason for the triggering of the sensor must be resolved.

Lifting sensor

If the appliance is raised by the housing during operation, the travel drive switches off and the cutting blades are stopped.

Bump sensors for obstacle detection

The appliance is equipped with sensors that ensure it changes its direction of travel if it encounters obstacles. When it encounters an obstacle, the top part of the deck is shifted slightly and the shock sensor is triggered.

Tilt sensor in direction of travel/sideways

If an upward or downward slope or a laterally inclined angle of 24° (45%) is reached in the direction of travel, the appliance is turned or the appliance changes its direction of travel.

Rain sensor

The appliance is equipped with a rain sensor that (when activated) interrupts the mowing procedure in case of rain, and ensures that the appliance returns to the charging station.

NOTE

The appliance can be operated reliably in the immediate vicinity of other automatic lawnmowers. The signal used in the boundary cable corresponds to the standard defined by the European Garden Machinery Industry Federation (EGMF) with regard to electromagnetic emissions.

4 ASSEMBLY

4.1 Unpacking the machine

1. Open the packaging carefully.
2. Carefully remove all components from the packaging and check for transport damage. Note: If there is any transport damage, immediately notify your Karcher dealer, technician or service partner in accordance with the warranty conditions.
3. Check the scope of supply, see chapter 2.1 "Scope of supply", page 39.

If the appliance is going to be sent on, retain the original packaging and accompanying documents. They will also be required for return shipment.

4.2 Planning the mowing areas (01)

Location of the charging station (01/1)

Shortest possible distance to the largest mowing area. Level surface. Protected against direct sunlight and harsh weather conditions. Connection option for power source. Free accessibility for the automatic lawn mower.

Routing the boundary cable (01)

The boundary cable must be laid in a continuous loop in a clockwise direction.

Corridors between mowing areas (01/h)

A corridor is a narrow section in the grass surface and can be used to connect two mowing areas.

Main area and secondary area(s) (01)

Main area (01/HF): This is the grass surface on which the charging station is located and whose entire surface can be mowed automatically by the appliance. Secondary area (01/NF): If a grass surface cannot be reached by the appliance from the main area, carry the appliance to the secondary area by hand if necessary. Secondary areas can be processed using manual operation.

The main area and secondary areas are bounded by the same continuous boundary cable, however.

Position of the entry points (01/X0 - 01/X3)

At the specified mowing time, the appliance moves along the boundary cable to the specified entry point and begins to mow there.

The entry points can be used to specify which areas of the mowing area are to be mowed several times.

4.3 Preparing the mowing areas

1. Check that the grass surface is larger than the area covered by the appliance. If the grass surface is too large, an irregularly mown lawn will result. Reduce the size of the grass surface to be mowed if necessary.
2. Before installation of the charging station and boundary cable or start-up of the appliance: Use a lawn mower to mow the grass surface to a low cutting height.
3. Remove any obstacles on the grass surface or exclude them with the boundary cable (see chapter 4.5.3 "Excluding obstacles", page 50):
4. Flat obstacles that will be run over and could damage the cutting blade (e.g. flat stones, transitions from the grass surface to the terrace or paths, plates, kerbs, stones, etc.) Holes and protrusions in the grass surface (e.g. molehills, burrowing holes, pine cones, fallen fruit, etc.)
5. Steep ascents and descents of more than 45% (24°).
6. Bodies of water (e.g., ponds, streams, swimming pools, etc.) and their demarcation from the grass surface. Shrubs and hedges that can become broader.

4.4 Setting up the charging station (03/a)

1. Place the charging station (01/1) at right angles to the planned location of the boundary cable as described below:

Level (check with a spirit level). Straight and level entrance and exit. Not arched (the charging pole must not bend or tilt during subsequent tightening of the grass screws). When placed on a wall: a distance of at least 5 cm.

1. Fix the charging station (03/2) to the floor with five grass screws (03/1).

4.5 Installing the boundary cable

NOTE

If the supplied boundary cable is too short, an extension cable can be obtained from your Kärcher dealer, technician, or service partner.

4.5.1 Connecting the boundary cable to the charging station (03/b)

1. Pull the boundary cable (03/4) out of the packaging.
2. Remove the cover of the cable shaft (03/3) on the connection (03/A).
3. Insulate the end of the boundary cable (03/6) and insert it into the terminal (03/7).
4. Close the terminal.
5. Lead the boundary cable through the strain relief (03/5) out of the cable shaft with cable reserve.

NOTE

The cable reserve allows smaller corrections to be carried out on the cable guide later.

1. Place the cover on the cable shaft.

4.5.2 Routing the boundary cable (01)

The boundary cable can be laid on the lawn and as much as 10 cm under the turf. Laying under the turf can be carried out by the dealer.

Both variants can be combined with one another.

IMPORTANT! Danger of damaging the boundary cable

If the boundary cable is damaged or cut, the transmission of the control signals to the appliance is no longer possible. In this case, the boundary cable must be repaired or replaced. The boundary cables are available from Kärcher.

Always route the boundary cable directly on the ground. If necessary, secure with an additional lawn peg. - When laying the boundary cable and during operation, protect the boundary cable from damage. - Do not dig or scarify in the vicinity of the boundary cable.

1. Attach the boundary cable at regular intervals with lawn pegs or route it underground (at a max. depth of 10 cm).
2. Route the boundary cable around obstacles: see chapter 4.5.3 "Excluding obstacles", page 50.
3. Create corridors between individual mowing areas: see chapter 4.5.4 "Enclosing corridors (01/h)", page 50.
4. Exclude excessive upward or downward slopes: see chapter 4.5.5 "Excluding downward slopes", page 50.
5. Create loops of cable: see chapter 4.5.6 "Creating loops of cable (07)", page 50.
6. After completing the routing of the boundary cable, connect to the connector (03/b) of the charging station: see chapter 4.5.1 "Connecting the boundary cable to the charging station (03/b)", page 49.

4.5.3 Excluding obstacles

Depending on the surroundings of the working area, the boundary cable must be routed at different distances to obstacles. Use the ruler that can be removed from the packaging to determine the correct distance.

NOTE

Exclusions are only necessary if they cannot be detected by the bump sensors of the appliance. Avoid too many or unnecessary exclusions.

Recesses that are smaller than 6 cm must be excluded, otherwise the appliance may cause damage.

Distance from walls, fences, beds: min. 20 cm (01)

The appliance moves along the boundary cable with an offset of 20 cm to the outside. Therefore, route the boundary cable at a distance of at least 20 cm from walls, fences, beds, etc.

Distance from terrace edges and paved paths (05)

If the terrace or path edge is higher than the grass surface, a distance of at least 20 cm must be complied with. If the edge of the terrace or path is at the same height as the grass surface, the cable can be routed exactly along the edge.

Distance of obstacles from the boundary cable (01)

If the boundary cables are precisely folded up away from the obstacle or towards the obstacle, i.e. distance 0 cm, the appliance moves beyond the boundary cable. Do not cross the boundary cables (02/c), but lay them parallel (01/e).

Routing the boundary cable around corners (06)

For inwards going corners (06/a): Route the boundary cable diagonally to avoid the appliance becoming caught in the corner. For outwards going corners with obstacles (06/b): Route the boundary cable in a point in order to avoid a collision of the appliance with the corner. For outwards going corners without obstacles: Route the boundary cable at an angle of 90°.

4.5.4 Enclosing corridors (01/h)

In the corridor the following distances must be complied with:

Total width: min. 60 cm Distance of the boundary cable to the edge: 20 cm Distance between the boundary cables: min. 30 cm

4.5.5 Excluding downward slopes

Downward slopes that are greater than 45% must be excluded with the boundary cable (45% = 45cm downward slopes per 1m horizontally).

4.5.6 Creating loops of cable (07)

Spare loops of cable should be incorporated at regular intervals in order to reposition the charging station or to extend the mowing area even after the mowing area has been laid out.

Select the number of spare cable loops according to your own judgement.

NOTE

In the case of spare cable loops, do not form open loops.

1. Lead the boundary cable around the current lawn peg (07/1) and then back to the previous lawn peg (07/3).
2. Then lead the boundary cable to the current lawn peg again. This creates a loop. The cables must be close together.
3. If necessary, attach the loop to the ground in the middle with an additional lawn peg (07/2).

4.5.7 Typical faults in cable routing (02)

• Spare cable loops of the boundary cable are not laid in an even, elongated loop (02/a). The boundary cable is not routed properly around corners (02/b). The boundary cable is crossed over or not routed clockwise (02/c).

The boundary cable is routed too imprecisely so that edge areas of the grass surface cannot be mowed (02/d). The boundary cable is not routed lying directly next to itself when guided towards and back from the edge to an obstacle inside the lawn (02/e). The entry points are set too far away from the charging station (02/f). The boundary cable is routed beyond the edge of the grass surface (02/g). When routing the boundary cable, the minimum distance for corridors of 30 cm is undercut (02/h). The boundary cable is routed too close (i.e. at a distance of less than 20 cm) to obstacles that cannot be driven over (02/i).

4.6 Connecting the charging station to the power supply (04)

1. Place the power supply (04/4) in a dry location that is protected against direct sunlight and sufficiently close to the charging station (04/1).
2. Connect the low voltage cable of the power supply (04/5) and the cable of the charging station (04/6) with each other.
3. Plug the power plug of the power supply (04/2) into a power socket (04/3).

NOTE

We recommend connecting the power supply to the mains supply via an earth leakage circuit breaker (ELCB) with a rated leakage current < 30 mA.

4.7 Checking the connections on the charging station (04)

1. Check that both LEDs on the front side of the charging station (09/1) light. If not:

Disconnect the mains plug. - Check that all plug connectors of the power source and the boundary cable are positioned correctly and check for damage.

Water in the automatic lawnmower and in the charging station leads to damage to electrical components.

• Do not spray the automatic lawnmower and charging station with water.

Cleaning the automatic lawnmower

CAUTION!

Danger of injury due to the cutting blade

The cutting blades are very sharp and can cause cutting injuries.

Wear protective gloves. Make sure that parts of the body do not get into the cutting blade.

Once a week, carry out the following:

1. Switch off the appliance with ON OFF.
2. Wipe off the surface of the housing with a broom, a brush, a damp cloth or a fine sponge.
3. Brush off the underside, mower deck and cutting blade with a brush.
4. Check the cutting blade for damage. If necessary, replace it: see chapter 9.3 "Replacing the cutting blades", page 58.

Cleaning the charging station

1. Regularly remove grass residues, leaves, or other objects from the charging station.
2. Wipe off the surface of the charging station with a damp cloth or a fine sponge.

9.2 Regular checks

General checks

1. Once a week, check the whole installation for damage:

Machine, charging station, boundary cable, power supply.

1. Replace defective parts with original spare parts from Kärcher or have them replaced by a Kärcher service centre.

Check the rollers can move freely.

Once a week, carry out the following:

1. Carefully remove grass residues and soiling from the areas around the rollers. Use a broom and cloth for this.
2. Check that the rollers run freely and that they can be steered.

Note: If the rollers do not move freely or cannot be steered, have them replaced by a Kärcher service centre.

Check the contact surfaces on the automatic lawnmower.

1. Use a cloth to remove soiling and then lightly grease with contact grease.

Check the charging contacts of the charging station

1. Disconnect the mains plug.
2. Press the charging contacts in the direction of the charging station and release them. The charging contacts must spring back into the initial position.

Note: If the charging contacts do not spring back, have them replaced by the Kärcher service centre.

9.3 Replacing the cutting blades

CAUTION! Danger of injury due to the cutting blade

The cutting blades are very sharp and can cause cutting injuries.

Wear protective gloves. Make sure that parts of the body do not get into the cutting blade.

IMPORTANT!

Damage to the appliance due to incorrect repair

The blade plate can be damaged by the alignment of a bent, built-in cutting blade.

• Do not align bent cutting blades.
• Replace bent cutting blades by original spare parts from Kärcher.

Worn or bent cutting blades must be replaced.

1. Switch off the appliance with ON OFF.
2. Put down the appliance with the cutting blades pointing upwards.
3. Unscrew the fastening screws.
4. Take the cutting blade out of the blade seat.
5. Clean the blade seat with a soft brush.

NOTE

The cutting blades are sharpened along the entire length and can therefore also be mounted rotated by 180°, which doubles their runtime.

1. Replacing the cutting blades:

If cutting blades have not been rotated since the initial mounting: Rotate the cutting blades by 180° and insert into the blade seat again with the sharpened side pointing towards the appliance, and tighten the fastening screws again by hand. If the cutting blades have already been rotated once since the initial mounting: Insert new cutting blades into the blade seat again with the sharpened side pointing towards the appliance, and tighten the new fastening screws by hand. Note: Only original spare parts from Karcher are allowed.

As a rule, the clearer blades do not need to be replaced.

In case of stubborn dirt that cannot be removed with a brush, the blade plate must be replaced because an imbalance can lead to increased noise levels, greater wear and malfunctions.

2 PRODUCT DESCRIPTION

This document describes a fully automatic battery-powered lawn mower that moves freely on the lawn. The cutting height is adjustable.

2.1 Scope of Delivery

The scope of delivery includes the listed items. Check that all items are present:

The battery is installed in the device and cannot be replaced by the user.

NOTE

Before first use, the battery must be fully charged. The battery can be charged at any charge level. Interrupting the charging process does not damage the battery.

The battery can only be charged when the device is switched on.

The built-in battery is included in the scope of delivery. During normal operation, the battery is charged regularly. For this purpose, the device is placed on the charging station. The built-in electronic monitoring system automatically stops the charging process when a 100% charge level is reached. The charging process only works if the charging contacts of the charging station are in perfect contact with the contact surfaces of the device. At temperatures above 45°C, the built-in protection circuit prevents the battery from being charged. This prevents the battery from being destroyed. If the battery runtime decreases significantly despite proper charging, the battery must be replaced by a specialist, technician, or the Karcher service partner with a new original battery. If the battery is discharged beyond the manufacturer's specifications due to aging or prolonged storage, it cannot be recharged. Have the battery and the electronic monitoring system checked by a specialist, technician, or the Karcher service partner and replace it if necessary. The battery status is displayed on the display. Check the battery status after 3 months of storage. To do this, switch on the device and read the battery status. If the battery is charged to approximately 30% or less, place the device on the charging station and switch it on to charge the battery. If the charging station was dismantled for storage (see Chapter 11.2 "Storage of the charging station", page 400), install it in reverse order and connect it to the mains again.

If the battery in the device is leaking: Contact the Karcher service center for repair! If the battery has been removed from the device and as a result electrolyte has leaked and come into contact with exposed skin or eyes: Rinse immediately with water and seek medical attention promptly!

2.9 Description of functioning

Behavior on the lawn

The device moves freely within the mowing area, which is defined by the boundary wire. The orientation of the device is carried out with the help of sensors that detect the magnetic field of the boundary wire.

If the device encounters an obstacle, it stops and continues moving in a different direction. If the device detects moisture, it automatically returns to the charging station. If the device gets into a situation where operation is not possible, a message appears on the display.

Working time, mowing time, charging

The mowing stages change constantly according to the charging stages. If the battery charge reaches a certain value during mowing (e.g., 0%), the device returns to the charging station along the boundary wire.

Preset mowing programs are provided for the mowing mode, which also include the function for mowing edges. These mowing programs can be changed.

The direction of rotation of the drive mechanism changes, which increases the service life of the blades.

If you want to return the device, keep the original packaging and the accompanying documents. They are also necessary for a return and for shipping.

4.2 Planning the mowing area (01)

Placement of the charging station (01/1)

Shortest route to the largest mowing area. Level surface. Protection from direct sunlight and strong weather conditions. Possibility of connecting to the power supply and free access for operation of the robotic lawnmower.

Laying the boundary cable (01)

The boundary cable must be laid without interruption and checked continuously.

Passage through mowing areas (01/h)

The passage is a narrow strip of lawn that can serve to connect two mowing surfaces.

Main and secondary areas (n) (01)

Main area (01/HF): The sensor, on which the charging station is installed, can automatically fold using the device on all areas. Additional area (01/NF): This is a sensor that the device cannot reach from the main area. The device must be manually moved to the additional area. Additional areas can be processed in continuous operation mode.

Both main and additional areas are enclosed by the same boundary cable.

Positioning of the input terminals (01/X0-01/X3)

The device is connected to the boundary cable with a fixed time for folding the fixed input terminals and begins with tampering.

The input terminals allow you to specify which areas of the folding area have been folded.

You can combine both variants.

WARNING!

Danger of damaging the boundary cable

If the boundary cable is damaged or torn, the device will no longer be able to receive control signals. In this case, the boundary cable must be repaired or replaced. The boundary cable is available from Karcher.

Always lay the boundary cable directly on the ground. If necessary, secure it with additional fasteners for fixing the boundary cable. Protect the boundary cable from damage during installation and operation. Do not dig or perform vertical work with the boundary cable.

1. Lay the boundary cable through the guide slots using the fasteners for fixing the boundary cable or with ground spikes (maximum 10 cm).
2. Lay the boundary cable around obstacles: see section 4.5.3 "Bridging obstacles", page 423.
3. Create passages between separate mowing areas: see section 4.5.4 "Creating passages (01/h)", page 424.
4. To exclude large slopes or transitions: see section 4.5.5 "Avoiding transitions", page 424.
5. Lay the charging cable: see section 4.5.6 "Laying the charging cable (07)", page 424. 6. After completing the installation, connect the boundary cable to the charging station (03/B) according to the connection diagram: see section 4.5.1 "Connecting the boundary cable to the charging station (03/b)", page 422.

4.5.3 Obstacles

Depending on the type of obstacle, the routing cable must be laid at different distances from obstacles. To determine the correct distance, use the ruler that is attached to the packaging.

RULER

Remove any obstacles that could be detected by the motion sensors of the device. Remove a large number of obstacles or unnecessary objects. Objects smaller than 6 cm must be insulated, otherwise the device may be damaged.

Distance to walls, fences, flower beds: min. 20 cm (01)

The device changes its direction when it is 20 cm away from the boundary cable. Therefore, lay the boundary cable at a distance of no less than 20 cm from walls, fences, flower beds, etc.

Distance to terrace edges and paved paths (05)

If the terrace or the edge is higher than the lawn, then a distance of no less than 20 cm must be maintained. If the terrace or the edge is at the same height as the lawn, then the cable can be laid exactly at the edge.

Distance between the boundary cable and obstacles (01)

If the boundary cable is laid without insulation directly next to an obstacle or on it, i.e., at a distance of 0 cm, the device will cross over the boundary cable. Do not cross the boundary cable (02/c), but lay it parallel (01/e).

Laying the boundary cable in corners (06)

For inner corners (06/a): lay the boundary cable diagonally to avoid the device getting stuck in the corner. For outer corners with obstacles (06/b): lay the boundary cable with a pointed end to avoid the device colliding with the corner. For outer corners without obstacles: lay the boundary cable at a 90-degree angle.

4.5.4 Passage width (01/h)

Maintain the specified minimum distances in passages:

Total width: min. 60 cm Distance of the boundary cable to the edge: 20 cm Distance between boundary cables: min. 30 cm

4.5.5 Height difference

If the height difference exceeds 45%, a shielded cable must be used (45% = a drop of 45 cm for every 1 m horizontally).

4.5.6 Laying cable slack (07)

To be able to move the charging station or expand the charging area after commissioning the charging area, adjust the cable slack in the shielded cable.

The amount of cable slack can be set at your own discretion.

NOTE

Indicates open loops in case of cable slack.

1. Lay the shielded cable along the belt fastener for mounting the shielded cable (07/1), and then

go to the cross fastener for mounting the shielded cable (07/3).

1. Then lay the shielded cable along the belt fastener for mounting the shielded cable, forming a loop. The cable must fit tightly.
2. If necessary, adjust the loop inside using the additional fastener for mounting the shielded cable (07/2) on the ground.

4.5.7 Typical errors during cable laying (02)

The shielded cable slack is not installed in a uniform surface loop (02/a). The shielded cable is correctly installed around corners (02/b). The shielded cable is crossed or not laid in the direction of the gas flow (02/c). The shielded cable is installed too far from the correct gas shut-off point (02/d). The transition point from the switch to the gas shut-off shielded cable is not laid directly at the switch (02/e). The entry point is installed too far from the charging station (02/f). The shielded cable is laid along the edge of the gas zone (02/g). During the laying of the shielded cable, the minimum distance for passage of 30 cm is exceeded (02/h). The shielded cable is located too close, i.e., at a distance of less than 20 cm, to obstacles that can be crossed (02/i).

4.6 Connecting the charging station to the power supply unit (04)

1. Place the power supply unit (04/4) in a dry place away from direct sunlight, in sufficient proximity to the charging station (04/1). 2. Connect the power cable of the power supply unit (04/5) and the cable of the charging station (04/6).
