2.1 General safety

DANGER!
- In the event of fire, use a fire extinguisher which is suitable for electrical devices.

WARNING!
- Only use the device as intended.
- Ensure that the red and black terminals never come into contact.
- Disconnect the device from the mains:
– Before cleaning and maintenance
– Before changing a fuse - If you disassemble the device:
- Detach all connections
- Make sure that no voltage is present at any of the inputs and outputs
- The device may not be used if the device itself or the connection cable are visibly damaged.
- If this power cable for this device is damaged, it must be replaced by the manufacturer, customer service or a similarly qualified person in order to prevent safety hazards.
-
This device may only be repaired by qualified personnel. Inadequate repairs may cause serious hazards.
-
People (including children) whose physical, sensory or mental capacities prevent them from using this device safely may not be allowed to operate it without the supervision of a responsible adult.
● Electrical devices are not toys.
Always keep and use the appliance out of the reach of children.
● Children must be supervised to ensure that they do not play with the device.

NOTICE!
- Before start-up, check that the voltage specification on the type plate is the same as that of the power supply.
- Ensure that other objects cannot cause a short circuit at the contacts of the device.
● Store the device in a dry and cool place.
2.2 Safety when installing the device

DANGER!
- Never mount the device anywhere where there is a risk of gas or dust explosion.

CAUTION!
- Ensure that the device is standing firmly. The device must be set up and fastened in such a way that it cannot tip over or fall down.

NOTICE!
- Do not expose the device to a heat source (such as direct sunlight or heating). Avoid additional heating of the device in this way.
- Set up the device in a dry location where it is protected against splashing water.
2.3 Safety when connecting the device electronically

DANGER! Danger of electrocution
● For installation on boats:
If electrical devices are incorrectly installed on boats, corrosion damage might occur. Have the device installed by a specialist (marine) electrician.
- If you are working on electrical systems, ensure that there is somebody close at hand who can help you in emergencies.

WARNING!
● Always use an adequate fuse in the positive line between the device and the battery.
● Make sure that the lead has a sufficient cross-section.
- Lay the cables so that they cannot be damaged by the doors or the bonnet.
Crushed cables can lead to serious injury.

CAUTION!
- Lay the cables so that they cannot be tripped over or damaged.

NOTICE!
- Use ductwork or cable ducts if it is necessary to lay cables through metal panels or other panels with sharp edges.
- Do not lay the 230 V mains cable and the 12 V DC cable in the same duct.
- Do not lay the cable so that it is loose or heavily kinked.
- Fasten the cables securely.
- Do not pull on the cables.
2.4 Operating the device safely

WARNING!
- Only use the device in closed, well-ventilated rooms.
- Do not operate the device in systems with lead acid batteries. These batteries give off explosive hydrogen gas that can be ignited by sparks on electrical connections.

CAUTION!
-
Do not operate the device
– In salty, wet or damp environments
– In the vicinity of corrosive fumes
– In the vicinity of combustible materials
– In areas where there is a danger of explosions. -
Before starting the device, ensure that the power supply lines are dry.
● Always disconnect the power supply when working on the device. - Please observe that parts of the device may still conduct voltage even if the fuse has blown.
- Do not disconnect any cables when the device is still in use.

NOTICE!
● Make sure the air inlets and outlets of the device are not covered.
- Ensure good ventilation.
2.5 Safety precautions when handling batteries

WARNING!
- Batteries contain aggressive and caustic acids. Avoid battery fluid coming into contact with your body. If your skin does come into contact with battery fluid, wash the part of your body in question thoroughly with water.
If you sustain any injuries from acids, contact a doctor immediately.

CAUTION!
- When working on the batteries, do not wear any metal objects such as watches or rings.
Lead acid batteries can cause short circuits which can cause serious injuries.
● Danger of explosions!
Never attempt to charge a frozen or defective battery.
Place the battery in a frost-free area and wait until the battery has acclimatised to the ambient temperature. Then start the charging process.
- Wear goggles and protective clothing when you work on batteries. Do not touch your eyes when you are working on the battery.
- Do not smoke and ensure that no sparks can arise in the vicinity of the engine or battery.

NOTICE!
- Only use rechargeable batteries.
- Prevent any metal parts from falling on the battery. This can cause sparks or short-circuit the battery and other electrical parts.
● Make sure the polarity is correct when connecting the battery. - Follow the instructions of the battery manufacturer and those of the manufacturer of the system or vehicle in which the battery is used.
- If you need to remove the battery, first disconnect the earth connection. Disconnect all connections and all consumers from the battery before removing it.

Quantity Description
1 Converter
1 Operating manual
4 Proper use
The transformers convert a 12 V--- or 24 V--- supply from a car or boat battery to a stable DC voltage:
- DC08 (item no. 9102500055), DC20 (item no. 9102500045), DC40 (item no. 9102500056): 12 V--- input voltage to 14.2 V--- output voltage (charge converter)
- DCDC10 (item no. 9102500057), DCDC20 (item no. 9102500058): 12 V--- input voltage to 27.6 V--- output voltage (voltage converter)
- DCDC20 (item no. 9102500059), DCDC40 (item no. 9102500060): 24 V--- input voltage to 13.8 V--- output voltage (voltage converter)
- DCDC10 (item no. 9102500061): 24 V--- input voltage to 27.6 V--- output voltage (voltage converter)
All the converters can also be use to charge lead batteries.

NOTICE!
Never use the device to charge other battery types (such as NiCd or NiMH).
The charge voltage has an IU charging characteristic with a charge voltage of 13.8 V/27.6 V.
On charge converters, the output voltage is regulated to 14.2 V. This means the battery is charged more quickly.

NOTICE!
Charge converter: Do not charge for longer than twelve hours.
5 Technical description
The light weight and compact construction allows the converters to be easily installed in mobile homes, commercial vehicles or motor and sailing vessels.
The transformers convert a 12 V=== or 24 V=== supply from a car or boat battery to a stable 12 V=== or 24 V=== voltage for connecting to equipment.
The isolation of the input and output voltages means the output voltage can be kept stable without interference from the input circuit.
Because the maximum output current is electronically regulated, the charge converters can be used to charge batteries to generate electricity in cars or on boats.
The devices are equipped with protection against shorting and overloading. If the protective function triggers, the device switches off and then switches on again when correctly connected or when the load has been adequately reduced.
