2.1.3 Battery MINI-EX-_ _ _
The explosion-proof battery type MINI-EX-_ _ _ is destined for the supply of portable,
intrinsically safe devices (e.g. radio transmitters) in hazardous areas. It has the duty to
restrict current to < 1,1 A in case of a short-circuit of the feeder clamp.
For the discharging process the battery is inserted in a corresponding battery compartment
of the operating device to be supplied. The battery should never be changed within the
hazardous area.
The spare battery can be taken into a hazardous area, but the operator has to keep it safe
at all times.
The battery must only be charged in HETRONIC battery chargers specially marked with EX,
type MINI UHC-2-AC-EX or MINI UHC-2-DC-EX and ONLY outside hazardous areas.
The battery housing consists of a black polyester moulding material. The non-antistatic
projected surface of the batteries is < 20 cm². The contacts of the EX-batteries are
interchanged to those of the standard batteries, in order to avoid operation of the intrinsically
safe device with wrong batteries.
Rechargeable battery packs are hazardous waste! Use a specialist
disposal company for recycling or disposal! Defective battery packs can
also be disposed of directly through HETRONIC!
