Changing batteries, charging batteries
The batteries of the explosion-proof units may be changed only outside of
hazardous areas. The company operating the system and the units is
responsible for performing battery replacements with the necessary care
and for adhering to the safety measures included into the design, i.e. the
correct fixing of the battery using the securing screw. You may never
GB separate batteries from the unit in hazardous areas. Charge the batteries
only outside of the hazardous areas. Use only the special charger
Tischladegerät FC1 S Ex, part no. 50 1018 1001 combined with its
dedicated plug-in power supply unit. The use of other chargers or plug-in
power supply units is strictly forbidden as the batteries may overheat and
be damaged.
Use of bag; explosion-proof units with and without a clip

areas, you may use two alternatives:
• Use of an explosion-proof unit with the clip mounted, combined with the
bag, manufacturer's part number 50 1011 7500
• Use of an explosion-proof unit without the clip mounted, carried in the
bag with the manufacturer's part number 50 1011 7501
Note: Explosion-proof units without the clip mounted may only be taken
in hazardous areas for operation, when beeing carried using the bag with

In addition the following requirements must be fulfilled:
1 Only specialists with a profound understanding of explosion protection
are allowed to dismount or mount the clip of an explosion-proof unit.
2 Explosion-proof units without the clip mounted must be inserted into their
bags with the manufacturer's part number 50 1011 7501 prior to be
carried into the hazardous areas.

withdrawn from their bags, manufacturer's part number 50 1011 7501

These bags are available as accessories. The use of other protective bags
is forbidden as they may represent an explosion hazard.
