Dangers from
mains current
and charging cur-
rent
Anyone working with chargers exposes themselves to numerous dangers e.g.:
- Risk of electrocution from mains current and charging current
- Hazardous electromagnetic fields, which can risk the lives of those using cardiac
pacemakers
An electric shock can be fatal. Every electric shock is potentially life threatening. To avoid
electric shocks while using the charger:
- Do not touch any live parts inside or on the outside of the charger.
- Under no circumstances touch the battery poles
- Do not short-circuit the charging lead or charging terminals
All cables and leads must be secured, undamaged, insulated and adequately dimen-
sioned. Loose connections, scorched, damaged or inadequately dimensioned cables and
leads must be immediately repaired by authorised personnel.
Dangers from ac-
id, gases and va-
pours
Batteries contain acid which is harmful to the eyes and skin. During charging, gases and
vapours are released that can harm health and are highly explosive in certain circumstanc-
es.
- Only use the chargers in well ventilated areas to prevent the accumulation of explosive
gases. Battery areas are not deemed to be hazardous areas provided that a concen-
tration 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 battery and charger during
the charging procedure. Possible sources of ignition, such as fire and naked lights,
must be kept away from the battery
- The battery connection (e.g. charging terminals) must not be disconnected for any
reason during charging
- On no account inhale any of the gases and vapours released
- 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, onto the skin or clothes. Wear protective gog-
gles and suitable protective clothing. Rinse any acid splashes thoroughly with clean
water, and seek medical advice if necessary.
General informa-
tion regarding the
handling of bat-
teries
- 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 occurs, 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.
- heating of the battery over 55 °C (131 °F).

EN
Protecting your-
self 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 opera-
tion
- 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 op-
erated 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 con-
dition 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 Clas-
sifications
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 sen-
sitive 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.

10
Maintenance and
repair
Under normal operating conditions, the device requires only a minimum of care and main-
tenance. However, it is vital to observe some important points to ensure it remains in a us-
able condition for many years.

The device can be set up and operated in dry, closed areas that comply with degree of pro-
tection IP20. Exposure to wet conditions should be avoided.
The device may only be operated in a hori-
zontal position.
The air surrounding the charger must be kept free from battery acid vapour as far as pos-
sible. You should therefore avoid mounting the device directly above the battery that is to
be charged.
Cooling air
The charger must be set up in such a way that the cooling air can flow unimpeded through
the vents in the housing that are provided for that purpose. Ensure that there is always a
minimum clearance of f 0.2 m (7.874 in.) around the air inlets and outlets. The surrounding
air must be free from
- excessive dust
- electrically conductive particles (carbon black or swarf)
- heat sources
Cooling air is drawn in and flows out as indicated by the arrows in the following illustrations.
NOTE!
Air inlets and outlets must never be covered, not even partially.
If several chargers are set up one behind the other, they should be offset.
16 kW: 60 cm (1 ft. 11.62 in.)
8 kW: 30 cm (11.81 in.)

16
If the chargers are arranged in a line one behind the other without being offset, the space
between the chargers must be as follows:
- Selectiva 8 kW: Minimum distance 30 cm (11.81 in)
- Selectiva 16 kW: Minimum distance 60 cm (1 ft. 11.62 in.)
