Type plate

The type plate shown below is a representation of the adhesive label placed on the device. Please be prepared, when contacting our service team, to assist us in exactly identifying your device. Refer to your generator's operating instructions for further information about finding the type plate.

3.2.1 A device description and intended use

As part of network backup, the power generator creates electricity that can be used in alternating operation as an “on-site operation” OR as a “building supply” (IT-TN version).

Your power generator creates electricity for the "on-site operation" mode as part of a network backup operation, through which you can supply a mobile distribution system with electricity. This enables mobile use of commercially available electrical devices with single-phase 230 V AC / 50 Hz or three-phase 400V AC / 50 Hz (depending on the equipment being used).

Your power generator has been designed for manual or automatic operation (remote start) with one or more electrical consumers. To protect against electric shock (i.e. current flowing through your body), automatic switch-off according to DIN VDE 0100-551: 2017-02 is used as the protective separation measure. The protective conductor system from the attached consumers will take over the earthing function. The terminal strip (Fig. 6-4) is used for connecting a suitable earth (e.g. an earthing stake). Proper is needed and it must be done by a qualified electrician.

In "building supply" mode (see Chapter 8.2, the power generator serves as an emergency power supply for a stationary system through a flexible cable connection. For this, there is a separate CEE 400 V / 50 Hz socket with white colour marking.

Your generator consists of an AC generator driven by a combustion engine that is bolted onto it. This unit is mounted elastically inside a closed, sound-insulated housing, and vibration dampers are used to ensure low vibration.

The unit generates AC (three-phase) current with a nominal voltage of 400 V at 50 Hz. More detailed technical data can be found in Chapter 14. An integrated voltage regulator ensures that the stability of the generated voltage is within the nominal rotational speed range. Power is taken through a spray-water-protected Schuko socket with nominal voltage of 230 V / 50 Hz 1\~ or CEE sockets for 230 V / 50 Hz / 1\~ or 400 V / 50 Hz / 3\~ (see Fig. 6-4).

The generator is only to be used outdoors within the indicated voltage, output, and nominal RPM ranges (see type plate).

The power generator must never be used for direct feed into other power distribution systems (e.g. public power supply) or be used with other power generation systems (e.g. other power generators).

The generator is not to be used in explosion-prone environments.

The generator is not to be used in environments where there is a risk of fire.

The generator must be operated according to the specifications in the technical documentation.

Every inappropriate use or all activities on the generator that are not described in this manual is prohibited misuse beyond the manufacturer's legally defined limits of liability.

3.2.2 Foreseeable misuse

Apart from the description of appropriate use, the lawmaker also requires concrete references to the results of “reasonably foreseeable misuse”. In a case of incorrect use or inappropriate handling of the generator the manufacturer's EU Declaration of Conformity, and automatically thereby also the operating licence, are nullified. For products with a manufacturer's warranty the manufacturer will reject any claims made under warranty for damages which were caused by misuse and its direct as well as indirect consequences.

In particular unauthorised misapplications include:

• operation of the generator takes place without valid checks for

- electrical safety

– checking that the stipulated servicing and maintenance work has been done

- operation of the generator taking place without the protective equipment installed by the manufacturer

- constructional or electrical modifications were made to the generator

• software was modified or changes were made to the generator's factory settings
• use of the generator by inadequately instructed operating personnel

Furthermore at all costs avoid the following Misuses:

• Never refuel the generator's own tank when the engine is running. The vibrations and strong exhaust streams during operation can lead to fuel spillage. This leads to an increased risk of explosion and fire and therefore danger to operating personnel, the environment and the device.
• Never refuel the generator's own tank when it is hot. Overflowing fuel and exhaust fuel vapours can ignite on hot parts of the device.
• Never open the generator's tank cover whilst it is running or if it is hot. Overflowing hot fuel and escaping fuel vapours can ignite on the device's hot parts.
• The generator is never to be connected up to another energy distribution system (e.g. public power supply) or to other power generating systems (e.g. other generators, solar plants, etc.). To start with this is usually not permitted by . In both cases this will inevitably lead to severe damage and possibly also severe injury.
• Never place the generator in explosion-prone environments. The individual components of the generator are not designed to be EX-protected.
• Never operate the generator in rooms, narrow pits or vehicles. The combustion exhaust gases contain poisonous substances including the odourless but deadly gas carbon monoxide (CO) which, when breathed in, can accumulate in cases of poor air circulation to reach deadly concentrations. Also a lack of fresh air circulation leads to overheating and possible damage to the generator right through to destruction.
• For the same reasons of risk, never divert exhaust gases for the purposes of heating rooms or vehicles.
• Never clean the generator with the aid of a high pressure cleaner or a strong jet of water.
• Never allow water to find its way inside the generator. Never pour water over the generator and never clean it using a water hose or a high pressure cleaner.
• Never operate the generator in any area where it could be flooded by high water or any other events. The device's protection class (see Chapter 14) allows operation with spray water, however not in the case of floods.

4.5 Danger zones and work areas

In order to be able to consider all of a machine's safety aspects and to comply with the safety and health protection requirements of the applicable standards and EU directives, we have assessed the use of your Generators in all of the phases that it will go through during its product service life (product life cycle). The following zones were defined on the Generators for this purpose: The danger zones and work places (work areas) around the generator are determined by the activities to be undertaken within the various phases in individual life cycles:

• Working zone: In this zone on and around the Generators (approx. 1 metre radius) the trained operating personnel (see Chapter 4.4 ) may operate and inspect the device in compliance with all of the safety and operating instructions given in the technical documentation. All other people (especially minors and people with disabilities) must remain outside this working zone.
• Danger zone: This zone must be kept free of all personnel during all phases of use and service life of the device. Any work in this zone is only to be undertaken by specially trained specialists if it is essential for the fulfilling of the task and if all of the protective equipment (PPE) needed is used. You must always comply with the following limits:

Product's service life phase Danger zone
Transport and installation	within a radius of 1m around or below the device
Operation within the outer limits of the device
Service and maintenance	Within the outer limits of the device when switched on Generators

Tab. 4-1 Danger zone on Generators

5 Checking the electrical safety

Checking electrical safety requires different measures that are only to be taken by authorized personnel. In doing so the pertinent VDE provisions, EN and DIN standards, in their valid versions, must be observed. For use at construction or assembly sites, the DGUV Information 203-032 edition of May 2016 must be observed. It defines special protective measures and rules of conduct for the commissioning and corresponding marking on the device.

You must especially never use defective or damaged consumers, cable connections or plug connectors, etc. (current-consuming equipment). They must be checked for proper condition at regular intervals (see Tab. 5-1)

On-site operation

earthing

The "on-site operation" mode (see Chapter 8.2.1), has been designed for manual or automatic (remote start) operation with one or more electrical consumers. To protect against electric shock (current flow through your body), the protective separation measure with equipotential bonding according to DIN VDE 0100-551:2017-02 is used. The protective conductor system of the attached consumer equipment takes over the function of the potential equalization device. The terminal (Fig. 6-4) is connected with this Potential equalization device connected. An earthing device is not needed in the "on-site operation" mode.

Your Generators corresponds to a Version A generator according to DGUV Information 032-203 issued in May 2016 when it is in "on-site operation" mode. A corresponding marking can be found on the device (see Fig. 3-3):

We strongly recommend that you also comply with the requirements of DGUV Information 203-032 for other purposes.

DANGER!

Dangerous electrical voltages will be present if several consumables are connected up without a working personal safety device.

Mortal danger from electrocution

▶ Never operate multiple consumables from the Generators without additional RCDs (residual current circuit breaker) for the second and each additional consumable.
▶ Check the personal protection according to the check intervals given in Tab. 5-1.

earthing

Supplying power to a building

In "building supply" mode (see Chapter 8.2.2) your Generators has been designed as a replacement network supply for feeding into stationary installations such as residential houses or public facilities. Suitable on-site protective measures must be implemented to protect against electric shock (current flow through your body). The generator is earthed through the power supply cable's and this earths the stationary system.

In addition to the details given above, the electrical safety of the Generators is to be checked by a qualified electrician at regular intervals. The periods between testing must be established in such a way that the Generators and all work equipment to be connected can, based on current general knowledge, operational experience or specific evidence, be safe to use in the period between the two inspections. (Examples in TRBS 1201, implementation instructions for §5 of BGV/GUV-V A3, BGI 594, BGI 608, Appendix 2, recommendation of BGI/GUV-I 5090 "Repeated testing of mobile electrical equipment").

NOTICE!

Do not apply load to the generator immediately after a cold start.

▶ Allow the generator engine to warm up for a few minutes before switching on a load when the generator has not been operating for more than eight hours (or for very low external temperatures).

7.4 Low load diesel engine operation

Internal combustion engines normally run most economically and environmentally friendly when they have reached their optimum operating temperature (with a coolant temperature from approx. 80°C). Prolonged operation well below the operating temperature or without a specific minimum load will have a negative effect on the service life. Incomplete combustion processes inside the engine will cause more and more deposits to form within the engine. If this operating state continues for too long or it is not compensated for by regular phases running at full load, this might result in a total engine failure and high repair costs in the worst case.

NOTICE!

Damage to the drive motor or other components in the generator that were caused by low load operation that is contrary to our recommendations (see below) and/or those of the engine manufacturer will void any warranty or liability claims.

NOTICE!

Avoid, as far as possible, short-term operation or operation without a load or with a basic load that is too low. Follow these recommendations if the engine manufacturer does not provide detailed information or he provides different information:

▶ Run your power generator at a minimum of 30% - 40% of the rated output (see Technical Data).
▶ Avoid short-term operations where the engine does not reach its operating temperature.
▶ Run the engine under maximum load for at least one hour at regular intervals (monthly).
▶ Take note of the instructions provided by the engine manufacturer

7.5 Turning off your power generator

8.2.2 Building supply operating mode

The "building supply" operating mode is used to supply stationary systems such as residential houses or public facilities. The generator serves as the emergency power supply to maintain power if the public power supply fails.

NOTICE!

For further steps it is assumed that the building is equipped with an emergency power supply, which was installed by a specialist company under the supervision of an electrician and that this was implemented in compliance with VDE 0100 Part 551 and VDN.

DANGER!

There is NO PERSONAL PROTECTION on the generator's side when using the power supply socket as no RCD (residual current circuit breaker) is installed!

Mortal danger from electrocution

▶ Installation and commissioning is only to be undertaken by a qualified electrician

▶ Personal protection (RCD) must be ensured on-site.

▶ Check the personal protection according to the check intervals given in Tab. 5-1.

The supply into the stationary system is through a flexible connection line (H07RN-F or comparable) in the supply distributor installed on-site through the CEE power socket (Fig. 7-3 with white colour marking). All other sockets are not usable in this operating mode.

Ensure that the flexible connection line is suitable for the selected operating conditions and power output requirements.

Conditions The following requirements must be met:

√ Generator is ready for operation.
√ The selection switch for the supply distributor is in the "Network" or "0" position.

WARNING!

Danger from machines suddenly starting up.

Risk of severe or even mortal injuries.

▶ You must ensure that all consumers in the stationary system's distribution network are switched off or disconnected from the network BEFORE you switch the supply distributor over to emergency power.
▶ Take note of the instructions in the supply distributor's operating manual.

NOTICE!

Ensure that there is a clockwise rotating field applied to the feed distributor at the sides of the emergency power infeed. The rotational field must be checked by a qualified electrician if there is no appropriate direction of rotation indicator on the supply distributor, (see Fig. 8-5).

Create the power feed connection

Proceed as follows to create a power feed connection between the generator and the on-site installed feed distributor:

1. Connect the flexible connection cable to the CEE socket with white colour code Fig. 7-3.
2. Connect the flexible connection line with the power socket to the on-site installed feed distributor.
3. Use the selection switch to choose the "building supply" operating mode Fig. 6-4.
4. Start the generator, see Chapter 7.3.
5. Set the selection switch on the supply distributor to "emergency power" position.

The emergency power supply is created.

The stationary system is fed by the generator.

8.3 Insulation monitoring

"On-site operation" mode is equipped with insulation monitoring with shut-off. The insulation monitoring provides electrical safety to the generator and to all connected consumers and cable connections during continuous operation.

A possible insulation fault is displayed in two stages:

1. Yellow warning light with warning tone:

a) There is an insulation fault with transfer resistance lower than 46 kΩ but higher than 23 kΩ in a current circuit of the power generator, the cable network or a connected consumer.

Result: Operation is still possible, and the main line circuit breaker is still on. However, the cause of the insulation fault must be fixed soon. If the insulation fault occurs only in connection with a specific consumer or cable connection, the corresponding part must not continue to be used.

If the fault continues to occur after all consumers have been unplugged, immediately contact service personnel.

1. Red warning light with warning tone:

a) There is an insulation fault with transfer resistance lower than 23 kΩ in a current circuit of the power generator, the cable network or a connected consumer.

Result: Operation is no longer possible, and insulation monitoring trips the main line circuit breaker. The power generator cannot be operated again until the cause of the insulation fault is fixed. If the insulation fault occurs only in connection with a specific consumer or cable connection, the corresponding part must not continue to be used.

If the fault continues to occur after all consumers have been unplugged, immediately contact service personnel.

To undo the POWERLOCK connection, perform the steps in reverse order. Before that, be sure to turn off the affected consumer and set the circuit breaker for the POWERLOCK BOX to "0" or "OFF" position.

9.2 Dummy load

The power generator has a dummy load with an output adapted to the drive engine. This is electrical load resistance that automatically creates a base load as soon as the engine is running below the specified load limit.

During extended operation at low load, deposits form in the engine that, with time, cause increased wear and possibly severe engine damage. Automatic switch-on of the dummy load increases the burn temperature enough that the deposits are completely removed. The control electronics turn the dummy load off automatically as soon as a consumer with adequate power is connected to the power generator. This ensures that the generator's full power is available at all times.

The dummy load is controlled automatically and requires no intervention by operating personnel. You can tell the dummy load is active when the control module display shows power output when no or only minor consumers are turned on (in the example below, 3 kW).

Fig. 9-2 Display with dummy load operating

9.3 External battery charging

The additional option for external battery charging ensures that the drive engine's starter battery is permanently charged. This increases safety of use by enabling trouble-free engine start-up (if the starter battery is in perfect condition). With this option, your Generators has an integrated automatically operated battery charger that is supplied with a 230 V AC connection.

WARNING!

Escaping corrosive acid fumes or sulphuric acid during and after the charging process. A risk of suffering severe or even deadly burns.

▶ Only work with acid-resistant protective equipment.
▶ Clean surfaces covered in acid immediately using adequate amounts of water.
▶ Only charge the starter battery in a well ventilated environment.

! WARNING!

During the charging process, never undo the cable connections to the starter battery. Before you start the power generator, you must end the charging process and let the starter battery rest with good ventilation for about 30 minutes.

10.4 Engine oil

The drive motor for your generator, like every internal combustion engine, requires the required engine oil for cooling and inner cooling. It is also very important to use the correct engine oil, both for refilling and when changing the oil, and to adhere the stipulated maintenance intervals. Refer to the accompanying operating and maintenance instructions provided by the engine manufacturer for all necessary information.

10.4.1 Changing the engine oil

In contrast to the operating and maintenance manual for the engine, your power generator has a built in suction pump for engine oil. All engine components important for changing engine oil and oil filters can be reached through the large maintenance hatches on the connection and maintenance side, see Fig. 6-2 and Fig. 6-3.

NOTICE!

Leaking engine oil contaminates the soil and groundwater.

▶ Use a suitable oil catching receptacle.
▶ Old oil is a special waste and may only be disposed of over suitably qualified collection points.

CAUTION!

The engine and operating equipment on the generator can get very hot while running.

Risk of burns

▶ Never touch any engine parts (in particular the exhaust system) for a few minutes after ceasing operation.
▶ Allow the engine to cool off for at least five minutes before changing or checking the engine oil.

To suction out used oil, you also need an oil-resistant hose whose diameter corresponds to the pump opening (see - ) a suitable oil collection pan (not included with delivery). Below, only the procedures that differ from the engine operating manual are explained. ²

Fig. 10-2 Manual oil scavenger pump

Conditions

Ensure that the following prerequisites are met before you change the engine oil:

√ The generator is turned off.
√ When it is still hot: Wait until the engine oil has cooled down to approx. 30° C – 50° C.
√ Let the cold engine appropriately warm up.

Do as follows to suction up the used oil:

1. Open the shut-off valve by pressing the valve anti-clockwise and downward.
2. Guide the hose into a suitable oil collection container.
3. Move the suction pump's hand grip Fig. 10-2 up and down until no more used oil comes from the engine.
4. Move the hand grip Fig. 10-2 to the bottom position.

The engine's used oil has been suctioned out.

NOTICE!

The other procedures for changing the engine oil correspond with the details given in the engine's operating and maintenance instructions. Take note of the other maintenance and disposal of operating equipment instructions that can be found there.

10.5 Checking the coolant

We have filled your power generator's cooling circuit with premium coolant that ensures long-term material compatibility, and protection from corrosion and frost. The specification G12+ additive is free of nitrite, amine, phosphate and silicate and is mixed to ensure frost protection to at least a -25°C ambient temperature. So as not to impair the protective effect, use only a maximum 50% mixture for refilling.

NOTICE!

Follow the engine's operating and maintenance manual for all work on the cooling system.

In deviation from this, follow these instructions:

▶ Check the coolant level only from the surge tank (Fig. Fig. 10-3) near the radiator. The fluid level should always be between the Maximum and Minimum marks.
▶ If the tank is empty, the cooling system must be ventilated!

CAUTION!

Hot surfaces and hot, pressurized fluid. Burn hazard.

▶ Never open the radiator cap when the engine is running or is hot.
▶ Before opening the radiator cap, let the engine cool down.
▶ Open the radiator cap slowly, so that the overpressure in the tank can dissipate slowly.

Fig. 10-3 Checking the coolant

11 Storage

It is important to store the device at a suitable storage location as soon as your generator is no longer being used.

• The storage location must be roofed and must not be subjected to standing water, aggressive vapours or soiling as well as major accumulation of dust.
• Protect your device with a cover made out of breathable material.
• Ensure that the storage temperature and air humidity lie within the specified limits (see Technical data).

NOTICE!

Due to the limited shelf life of the different operating fluids, it is important for decommissioning for more than one month that additional measures for storage are taken. While doing this observe the instructions given in the attached operating and maintenance instructions from the engine manufacturer.

12 Disposal

Your device, which is an electrical or electronic device, is subject to European Directive 2012/19/EU ("WEEE directive") which is implemented in Germany in national law through the decree regulating the use of dangerous substances in electrical and electronic equipment (ElektroStoffV). This regulates disposal and use of recycling waste electrical equipment. The adjacent icon with a crossed-out wastebasket on your device states that it must not be disposed of in the household waste at the end of its service life.

As a private end-user (a so-called b2c customer) there are free collecting points (recycling centre) near you for electrical equipment as well as possible also other collection points available for reuse of devices. The addresses can be obtained from your city or communal authority. In as far as the old electrical and electronic equipment contains personal data, you are responsible yourself for its deletion before giving it back.

Pure b2b devices (devices which, for appropriate use, or exclusively are only used the commercial area) must not be disposed of over public collecting points in Germany and further EU countries. Speak to your authorised ENDRESS generator dealer about handing back your recycling waste electrical equipment. The dealer is also your point of contact for any differing regulations on the respective country of deployment. There are also possible agreements in the purchase contract to observe.

Please observe the pertinent environmental protection regulations when disposing of the old oil. We recommend bringing the oil in a closed container to an old oil collection centre for disposal. Never put used engine oil in the domestic waste. Storage or introduction of old oil into nature is associated with very high fines.

An inappropriately disposed of battery can greatly damage the environment. Give back your old battery directly free of charge to your dealer when purchasing a new one.

Always observe the valid local regulations and laws concerning correct disposal of all old parts and operating materials. Please contact your ENDRESS service partner for a replacement.
