FC1 Ex – Safety Instructions
Instructions and regulations
• All units and batteries carry the CE mark of conformity. In hazardous
areas, only explosion-proof units with the associated explosion-proof
batteries may be used. These units and batteries are provided with an
Ex marking.
• The present instructions will not replace the operating instructions to be
prepared by the operating party.
• The chargers are not explosion-proof and may therefore be
installed and operated only outside of hazardous areas!
Use of units in hazardous areas
Only such units may be operated in hazardous areas which
" "
comply with the basic requirements on safety and health as
defined in regulation 94/9/EC. Explosion-proof units meeting these require-
ments carry the CE mark of conformity, followed by the identifier of the
referenced agency supervising the quality assurance system, and the
explosion-proof symbol
Hazard degree of hazardous areas
There are hazardous areas (zones) with different hazard degrees. The
units may be operated only in those zones where the hazard degree is not
higher than the one the manufacturer has specified on the unit as unit
group and category. The company operating the units and the system is
responsible for defining these zones.
Batteries for explosion-proof units
Operate explosion-proof units only with suitable explosion-proof batteries
which are approved for the unit! Allowed combinations of units and
batteries can be identified by the information on the unit housing. The use
of other batteries which are not expressly approved is strictly forbidden as
otherwise the operating permit for those units in hazardous areas will
cease due to the lack of explosion protection and the unit will therefore
represent a safety risk!
Allowed combination:
Explosion-proof units may only be operated with the allocated explosion-
proof rechargeable battery. Follow the reference to the battery pack,
written on the housing of the FC1 Ex.
