EN

Danger due to ac­id, gases and va­pours

Batteries contain acid which is harmful to the eyes and skin. During charging, gases and
vapours are released that may be harmful to health and are highly explosive in certain cir­cumstances.

- Only use the charger in well-ventilated areas to prevent the accumulation of explosive
gases. Battery rooms are not deemed to be hazardous areas provided that a concen­tration of hydrogen of less than 4% can be guaranteed by the use of natural or forced
ventilation.

- Maintain a distance of at least 0.5 m (19.69 in.) between the battery and charger dur­ing the charging procedure. Possible sources of ignition such as fire and naked flames
must be kept away from the battery

- The battery connection (e.g. charging terminals) must not be disconnected for any
reason during charging

- Do not inhale any of the gases and vapours released under any circumstances

- Make sure the area is well ventilated

- To prevent short circuits, do not place any tools or conductive metals on the battery

- Battery acid must not get into the eyes or onto the skin or clothes. Wear protective
goggles and suitable protective clothing. Rinse any acid splashes thoroughly with
clean water and seek medical advice if necessary.

General informa­tion regarding the
handling of bat­teries

- Protect batteries from dirt and mechanical damage.

- Store charged batteries in a cool place. Self discharge is kept to a minimum at approx.
+2 °C (35.6 °F).

- Every week, perform a visual inspection to ensure that the acid (electrolyte) level in
the battery is at the Max. mark.

- If any of the following occur, do not start the device (or stop immediately if already in
use) and have the battery checked by an authorised workshop:

- uneven acid levels and/or high water consumption in individual cells caused by a

possible fault.

- overheating of the battery above 55 °C (131 °F).

Protecting your­self and others

While the charger is in operation, keep all persons, especially children, out of the working
area. If, however, there are people in the vicinity,

- warn them about all the dangers (hazardous acids and gases, danger from mains and
charging current, etc.),

- provide suitable protective equipment.

Before leaving the work area, ensure that people or property cannot come to any harm in
your absence.

Safety measures
in normal opera­tion

- Chargers with a ground conductor must only be operated on a mains supply with a
ground conductor and a socket with a ground conductor contact. If the charger is op­erated on a mains supply without a ground conductor or in a socket without a ground
conductor contact, this will be deemed gross negligence. The manufacturer shall not
be held liable for any damage arising from such usage.

- Only operate the charger in accordance with the degree of protection shown on the
rating plate.

- Never operate the charger if there is any evidence of damage.

- Arrange for the mains cable to be checked regularly by a qualified electrician to ensure
the ground conductor is functioning properly.

- Any safety devices and parts that are not functioning properly or are in imperfect con­dition must be repaired by a qualified technician before switching on the charger.

- Never bypass or disable protection devices.

- After installation, an accessible mains plug is required.

EMC Device Clas­sifications

Devices in emission class A:

- Are only designed for use in industrial settings

- Can cause line-bound and radiated interference in other areas

Devices in emission class B:

- Satisfy the emissions criteria for residential and industrial areas. This is also true for
residential areas in which the energy is supplied from the public low-voltage mains.

EMC device classification as per the rating plate or technical data.

EMC measures In certain cases, even though a device complies with the standard limit values for emis-

sions, it may affect the application area for which it was designed (e.g. when there is sen­sitive equipment at the same location, or if the site where the device is installed is close to
either radio or television receivers).
If this is the case, then the operating company is obliged to take appropriate action to rectify
the situation.

Data protection The user is responsible for the safekeeping of any changes made to the factory settings.

The manufacturer accepts no liability for any deleted personal settings.

Maintenance and
repair

Under normal operating conditions, the device requires only a minimum of care and main­tenance. However, it is vital to observe some important points to ensure it remains in a us­able condition for many years.

General information

Principle

The main feature of the new Active Inverter
Technology is intelligent charging. This me­ans that the charging behaviour adapts its­elf automatically to the age and state of
charge of the battery. This innovation ex­tends the battery life and reduces the
amount of maintenance required, while at
the same time improving cost-effective­ness.

Active Inverter Technology is based on an
inverter with active rectification and an intel­ligent safety cut-out. The charging current
and voltage are held constant by a digital
control that is not affected by any fluctua­tions in the mains voltage.

Device concept The compact design reduces space requirements and makes portable use considerably

easier. Add to this the fact that the active inverters can be used "on-board". In addition to
its many existing features, the charger has a modular design that makes it easy to upgrade;
it is therefore ideally equipped for future requirements. A wide range of options is available.

Warning notices
on the device

A number of safety symbols can be seen on the charger's rating plate. The safety symbols
must not be removed or painted over.

Do not use the functions until you have read all the operating instructions.

Possible sources of ignition, such as fire, sparks and naked flames, must be kept
away from the battery.

Risk of explosion! Oxyhydrogen is generated in the battery during charging.

Battery acid is corrosive and MUST be kept away from eyes, skin and clothes.
