2. EXPLANATION OF SYMBOLS

The symbol with a lightning bolt in a triangle is used where there is a health hazard, e.g. from electric shock.

The exclamation mark in a triangle indicates important notes in these operating instructions that must be observed strictly.

This symbol marks a connection terminal for ground potential on the inverter.

The product corresponds to protection class II.

The product is intended for use in dry indoor rooms only; it must not become damp or wet.

Observe the operating instructions.

3. SCOPE OF DELIVERY

• Inverter
• Operating instructions

The inverter produces a sine-like alternate voltage of 230 V/AC, 50 Hz from a direct voltage (depending on inverter version, either 12 V/DC or 24 V/DC).

• Item no. 1277756, 1277761, 1277764: Operating voltage 12 V/DC
• Item no. 1277765, 1277766, 1277767: Operating voltage 24 V/DC

Since the mains voltage is, however, only sine-like, but not precisely sine-shaped, we cannot guarantee that all electrical consumers can be operated via the inverter without problems.

The maximum output of the inverter and other important indices can be found in chapter "Technical Data" at the end of these operating instructions.

Electrical consumers with a higher rated power intake than the maximum permanent output of the inverter must not be connected.

When connecting electrical consumers (e.g. drill, refrigerator, etc.), to the inverter, observe that they often need a higher output than indicated on the rating plate of the consumer for a short period when switching on or starting up. The inverter therefore briefly supplies a higher output.

The inverter switches off on its own when the input voltage drops below a specific value. This protects a car battery from harmful deep discharge.

The safety notes and all other information in these operating instructions always have to be observed! Read these operating instructions with care before connection and commissioning. Keep these operating instructions or pass them on to a third party only together with this product.

Any use other than that described above can damage the product and may involve additional risks such as short circuit, fire, electric shock, etc. No part of this product must be modified or converted!

This product complies with the statutory national and European requirements.

The guarantee/warranty will expire if damage is incurred resulting from non-compliance with the operating instructions! We do not assume any liability for consequential damage!

We do not assume any liability for damage to property or personal injury caused by improper use or the failure to observe the safety instructions! In such cases the warranty/guarantee is voided.

Dear Customer, the following safety instructions are intended not only for the protection of your health but also for the protection of the product.

Therefore, read the following items very carefully before connecting the product and taking it into operation.

a) General information

• The unauthorized conversion and/or modification of the product is inadmissible for safety and approval reasons (CE). Never dismantle the product.
• Maintenance, adjustments and repair work may only be carried out by a specialist/specialised workshop.
• The product is not a toy and must be kept out of the reach of children!
• Do not leave packaging material unattended. It may become a dangerous toy for children.
• Never touch the inverter or any cables with wet or damp hands; danger to life from electric shock!
• Protect all cables from damage. Damaged cables must no longer be used.
• Place the cables where no one can trip over them.
• Never touch the inverter or any cables of the connected consumer if they are damaged; danger to life from electric shock!

First switch off the inverter and disconnect it from the voltage/current supply.

- Handle the product with care. It can be damaged by impact, blows or when dropped even from a low height.

• Observe the operating instructions of all devices that are connected to the inverter.
  • If you are not sure about the correct connection or use of the inverter, or if questions which are not covered by these operating instructions arise, please do not hesitate to contact us or another qualified specialist.

b) Site of setup

• Keep children away from the product. Choose the site of setup so that children cannot reach it. Children may try to stick objects into the device. There is danger to life from electric shock!
• The product is only suitable for operation in dry, closed rooms. The entire product must never become moist or wet. There is a fatal danger from electric shock!
• Choose a solid, flat, clean and sufficiently large surface for the product.

- Avoid the following unfavourable ambient conditions at the site of setup, during storage or when transporting:

• dampness or too-high humidity
• Cold or heat, direct solar radiation
• dust or flammable gases, fumes or solvents
• strong vibration, impact or blows,
• strong magnetic fields such as those near machines or speakers

- Do not place the product next to a radiator, fan, air conditioning or similar. Keep the product away from dust and dirt.

• The product has an installed fan. Place the product so that the fan cannot suck in any loose objects, curtains, etc. This not only poses a danger of damage to the product, but also a danger of fire.
- Never place the product on a flammable surface (e.g. carpet, tablecloth). Always use a suitable, non-flammable, heatproof surface.

- Do not place the product on any valuable furniture surfaces without using suitable protection. Heat may cause colour or material changes. Scratches of pressure points on the furniture surface are possible as well.

- Keep the product away from easily inflammable materials (e.g. curtains, paper), liquids (e.g. petrol) or gases. There is a risk of fire and explosion!

This specifically applies to gases escaping from rechargeable batteries (e.g. for lead batteries). Therefore, observe the corresponding ventilation and do not place the inverter and the rechargeable battery in the same room.

• Keep the inverter away from sources of open fire (e.g. candles), and do not place them on the inverter.
• The product must be easily accessible so that it can be disconnected from the voltage source or the consumer quickly in case of error.
• Avoid operation in direct proximity of strong magnetic or electromagnetic fields, transmitter aerials or HF generators. This can affect the control electronics.
• Do not place any containers filled with liquid, e.g. vases or plants, on or next to the product.

Liquids entering the inverter will destroy it. There also is the utmost risk of potentially fatal electric shock.

In this case, disconnect the product from the voltage/current supply at once. No longer operate the product. Have the product inspected by a specialist workshop or dispose of it environmentally compatibly.

- Secure or attach the inverter and all cables, e.g. when using them in a vehicle, so that proper operation of the vehicle is ensured and the inverter cannot come loose.

c) Connection to a direct voltage source

Do not wear any metal or conductive materials, such as jewellery (necklaces,

bracelets, rings, etc.). A short circuit causes a danger of injury, fire and explosion.

- The connection cable with cigarette lighter plug is firmly installed to the inverter. If an extension cable is used, it must have a sufficiently sized line cross-section. If the line cross-section is too small, the connection cable may grow hot. There is a danger of fire!

Very strong overheating may also cause a defect to the insulation of the connection cable, which may cause short circuit. There is a risk of explosion by the rechargeable battery.

• Keep the connection cable as short as possible.
• Always observe the correct polarity (plus/+ and minus/--) for connection. The middle contact of the cigarette lighter plug is the plus pole (+), the outer contact is the minus pole (-).

Check the polarity of the cigarette lighter socket used before connecting the inverter.

- Depending on the power taken from the inverter, the direct voltage source (e.g. a car battery) must be able to supply the corresponding current strength.

However, never replace the fuse in your vehicle for the cigarette lighter socket with any other fuse (with a higher rated value), since this may damage the vehicle electronics. There also is a danger of fire!

- Check all connections for tight fit and good electrical contact at regular intervals. High transfer resistances not only reduce the performance of the inverter but also may cause overheating and fire.

- The inverter must not be connected to electrical systems (e.g. a motor vehicle) where the plus pole is grounded or connected to the chassis of the vehicle.

d) Mains voltage output

Do not pull the mains plug from the mains socket of the inverter by pulling the cable.

Never connect the 230 V output of the inverter to another 230 V source (e.g. a mains socket). The inverter must not be used to feed mains voltage into an electrical building installation.

- If devices with protective ground plugs are connected to the mains socket of the inverter, the inverter may need to be earthed. For this, there is a corresponding connection at the inverter available (marked with the earthing symbol, see symbol on the right).

The earthing line to be used (green/yellow cable) must have a cross-section of at least 6 mm ^4 .

e) Operation

- Do not operate the inverter unsupervised.

- Even after triggering the internal protective device, parts of the inverter may still be live!

- The housing of the inverter will heat up in operation (depending on the output). Therefore, always observe sufficient ventilation of the inverter; never cover it in operation. Never close the ventilation slots of the inverter.

Keep a minimum distance of 5 cm from other devices around the housing of the inverter.

- Never operate the inverter immediately after it has been taken from a cold room to a warm room. The resulting condensation may lead to malfunctions or damage! Moreover, there is the risk of a fatal electric shock!

Let the inverter reach room temperature before connecting and operating it. This may take several hours!

• Only operate the inverter in a moderate climate, never in a tropical climate.
  For more information on acceptable environmental conditions, see the chapter "Technical Data".
• Never overload the inverter. In spite of comprehensive protective circuits, a defect or damage to the inverter or the connected devices cannot be fully excluded.
• The inverter is not approved for operation in connection with life-supporting medical devices.
• Disconnect the inverter from the voltage/current supply when you do not need it anymore. Keep it in a dry, cool, dust-free place that is inaccessible to children.
• In schools, training centres, hobby and self-help workshops, the use of the product must be supervised by responsible trained personnel.
• In commercial institutions, the accident prevention regulations of the Employer's Liability Insurance Associations for Electrical Systems and Operating Materials are to be observed.

6. CONNECTION TO THE VOLTAGE SOURCE

Before connecting the inverter and taking it into operation, read the entire operating instructions; specifically observe the chapter "Safety Notes".

- Check if the input voltage indicated on the inverter matches the voltage of the cigarette lighter socket used by you.

Also observe that the polarity of the cigarette lighter plug matches that of the cigarette lighter socket used. The middle contact of the cigarette lighter plug is the plus pole (+), the outer contact is the minus pole (-).

If this is not the case, the inverter must not be connected to the cigarette lighter socket.

• After the above inspection, plug the cigarette lighter plug of the inverter into the cigarette lighter socket completely to the stop.
• The inverter is now ready for operation, the "Power" LED must be lit.

For most vehicles, voltage is only applied to the cigarette lighter socket when the ignition of the vehicle is switched on.

The connection cable with cigarette lighter plug is firmly installed to the inverter. If an extension cable is used, it must have a sufficiently sized line cross-section. If the line cross-section is too small, the connection cable may grow hot. There is a danger of fire!

Very strong overheating may also cause a defect to the insulation of the connection cable, which may cause short circuit. There is a risk of explosion by the rechargeable battery.

The following applies: The larger the line cross-section and the shorter the cable, the lower the voltage drop on the line.

A too-high voltage drop on the line may cause premature undervoltage deactivation of the inverter.

Secure or attach the inverter and all cables, e.g. when using them in a vehicle, so that proper operation of the vehicle is ensured and the inverter cannot come loose.

Which consumers that are operated with mains voltage (230 V/AC, 50 Hz) can be connected to a inverter?

Generally, all consumers can be operated on a inverter.

However, many consumers have a higher power consumption at the moment of switching on than their rating plate says. This does not have any great importance when connecting to the public mains, since there are always the corresponding power reserves.

The inverter is limited in its output. However, it may supply a peak output briefly to balance out the high consumption at the moment of activation of the consumer.

If the consumption at the moment of activation of the consumer is higher than the peak output of the inverter (or if it takes too long), the overload protection of the inverter will be activated. The consumer cannot be connected and operated at the inverter.

Examples:

• A small compressor-operated refrigerator with a rated power of approx. 50 W may have ten times the power consumption (500 W) for three seconds after activation, since the electrical motor starts.
• A light bulb rated power of approx. 60 W may have ten times the power consumption (600 W) for one second after activation, since the low-impedance spiral-wound filament heats up. Only as the temperature rises will the electrical impedance increase as well so that the power consumption drops to rated output.

Due to the many different electrical consumers, it is not possible to provide a precise list of where problems are to be expected.

For example, consumers with integrated electrical motor, capacitors in mains units, devices with inductive load or light bulbs or heating radiators are problematic.

After connection of the inverter to the voltage source (e.g. a car battery), you may take the inverter into operation:

• When connecting the inverter to a cigarette lighter socket, observe chapter 6.
• The "Power" LED of the inverter lights up and indicates readiness for operation.

For most vehicles, voltage is only applied to the cigarette lighter socket when the ignition of the vehicle is switched on.

If the ignition is on and the “Power” LED does not light up, read the chapter “Removal of interferences”.

- Connect a consumer to the mains socket of the inverter.

The rated power of the consumer (see rating plate on the consumer or in its operating instructions) must not exceed the output of the inverter.

The consumer is ready for operation.

• The "Fault" LED will light up at overload, overtemperature or undervoltage recognition.
• If you want to terminate operation of the inverter, disconnect the consumer from the inverter and then pull the cigarette lighter plug of the inverter from the cigarette lighter socket.

Using a USB output socket:

This connection may be used, e.g., to charge a smart phone or tablet computer.

The USB output socket supplies a voltage of 5 V/DC and a current of up to 2 A. For this, the inverter must be connected to the voltage/current supply (“Power” LED is lit).

a) Undervoltage protection

The inverter emits an alarm sound when the input voltage drops below a specific value:

12 V inverter: Voltage drops below 10.5 V/DC (tolerance ±0.5 V/DC)

24 V inverter: Voltage drops below 21.0 V/DC (tolerance ±0.5 V/DC)

If the input voltage drops further, the inverter and the connected consumer are switched off. This protects, e.g., a car battery that is used to operate the inverter, from harmful deep discharge.

12 V inverter: Voltage drops below 10.0 V/DC (tolerance ±0.5 V/DC)

24 V inverter: Voltage drops below 20.0 V/DC (tolerance ±0.5 V/DC)

→ The “Fault” LED will light up if the inverter recognises undervoltage.

Terminate operation of the inverter; disconnect the consumer from the inverter and then pull the cigarette lighter plug of the inverter from the cigarette lighter socket.

If the undervoltage protection is activated, the USB output may not switch off in some circumstances. Disconnect thus the load which is connected to the USB output from the inverter after activating the undervoltage protection.

b) Overvoltage protection

The inverter switches itself and the connected consumer off once the input voltage is too high.

12 V inverter: Voltage rises over 15.0 V/DC (tolerance ± 0.5 V/DC).

24 V inverter: Voltage rises over 30.0 V/DC (tolerance ± 0.5 V/DC).

→ The “Fault” LED will light up if the inverter recognises overvoltage.

Terminate operation of the inverter; disconnect the consumer from the inverter and then pull the cigarette lighter plug of the inverter from the cigarette lighter socket.

Check the voltage source.

c) Overload protection

The inverter switches itself off temporarily if the consumer connected to the output draws too much power. If the power consumption is reduced, the inverter will switch on again automatically.

The "Fault" LED will light up at overload.

Terminate operation of the inverter; disconnect the consumer from the inverter and then pull the cigarette lighter plug of the inverter from the cigarette lighter socket.

Remove the cause of the overload.

d) Overtemperature protection

The conversion of input voltage to mains voltage and the resulting conversion loss produces heat due to the working principle. An integrated fan helps to cool the electronics of the inverter.

Depending on the power intake of the connected consumer or the ambient temperature, the inverter may overheat.

In this case, the inverter will switch itself off. After the inverter has cooled off sufficiently, it will switch on again.

The “Fault” LED will light up if the inverter recognises overtemperature.

e) Polarity reversal protection

If the polarity of the input is swapped when connecting, the inverter will not work and cannot be switched on.

Always observe the correct polarity (plus/+ and minus/−) for connection. The middle contact of the cigarette lighter plug is the plus pole (+), the outer contact is the minus pole (−).

The polarity of the cigarette lighter plug must match that of the cigarette lighter socket used.

9. FUSE REPLACEMENT

If the fuse in the cigarette lighter of the inverter has tripped, it must be replaced as follows:

• Disconnect the consumer from the inverter, pull the mains plug of the consumer from the socket of the inverter.
• Pull the cigarette lighter plug of the inverter from the cigarette lighter socket.
• Remove the cause that tripped the fuse. This may be a connection with swapped polarity or a consumer connected to the inverter with a too-high power consumption.
• Open the cigarette lighter plug by unscrewing the knurled nut at the tip of the plug.
• Replace the defective fuse by a new one of the same build. Observe the print on the fuse or the chapter “Technical Data”.
• Screw together the cigarette lighter plug, tighten the knurled nut by hand.
• The inverter can now be put into operation again.

10. MAINTENANCE AND CLEANING

The product does not require any maintenance. You should never take it apart.

The product should only be repaired by a specialist or specialist workshop or it may be damaged. Furthermore, the CE approval and the guarantee/warranty will expire.

Before cleaning, switch off the product and disconnect it from the voltage/current supply. Disconnect any connected consumer as well.

Only clean the product with a soft, clean, dry and lint-free cloth. Never use any cleaning agents, since this might damage the surface of the casing and label.

Dust can be removed using a clean, soft brush and a vacuum cleaner.

Inverter does not work, "Power" LED is not lit.

• For most vehicles, voltage is only applied to the cigarette lighter socket when the ignition of the vehicle is switched on.
• The cigarette lighter plug is not completely inserted into the socket or the plug does not make contact. Pull the cigarette lighter plug from the cigarette lighter socket and plug it back in.
• The fuse in the cigarette lighter plug has tripped. Check the fuse and replace it if required.
• The fuse in the cigarette lighter socket in the vehicle has tripped. Check the fuse and replace it if required.
• The polarity of the cigarette lighter socket does not match that of the cigarette lighter plug of the inverter.

The middle contact of the cigarette lighter plug is the plus pole (+), the outer contact is the minus pole (-).

The inverter works only with a consumer with a lower power consumption.

- The connection cable is too long or the line cross-section is too low (e.g. when an extension cord is used). Replace the connection cable by a shorter one; use a cable with a larger line cross-section.

Try operating the inverter without an extension cord.

- The consumer's power consumption is too high for the inverter.

- The consumer's power consumption is too high when starting up.

The connected consumer is not working and the "Fault" LED is lit.

• The consumer's power consumption is too high for the inverter; overload protection has been activated.
• The consumer's power consumption is too high when starting up; overload protection has been activated.

An alarm sounds.

- Undervoltage recognition has been activated. The rechargeable battery that is used for voltage/current supply of the inverter is flat.

Terminate operation of the inverter; disconnect the consumer from the inverter and then pull the cigarette lighter plug of the inverter from the cigarette lighter socket.

Charge the vehicle battery again or connect the inverter to another, fully charged battery.

- The overtemperature protection has been activated.

Terminate operation of the inverter; disconnect the consumer from the inverter and then pull the cigarette lighter plug of the inverter from the cigarette lighter socket.

Let the inverter cool off sufficiently.

Check if the inverter is sufficiently ventilated.
