1. Introduction
Providing an intense bright inspection light beam, the intrinsically
safe rechargeable handlamp type H-4 DC A is certified for use in
Ex-hazardous areas classified as either Zone 1 or 2 and also Zone
21 or 22 according to IEC/CENELEC.
2. Safety information
Safe operation of the equipment is maintained providing that all
instructions and warnings contained in this manual are fully
observed. In case of doubt (due to translation and/or printing
errors) reference should be made to the original German
instruction manual.
3. Faults and damage
If there is any reason to suspect that the safety of the unit has
been affected then it must be immediately withdrawn from use and
precautionary measures taken in order to prevent any further use
of in the hazardous area.
The safety and integrity of the unit may be compromised by, for

• External damage to the housing
• Exposure to excessive loads
• Incorrect storage of the unit
• Damage sustained in transit
• Correct certification is illegible
• Functioning errors occur
• The permitted limitations are exceeded

4. Safety regulations
The use of the intrinsically safe H-4 DC A meets the requirements
of the regulations providing that the user observes and applies the
requirements as laid down in the regulations and that improper
and incorrect use of the unit is avoided.
• The device must not be opened within the Ex-hazardous area.
• Batteries must only be changed outside of the Ex-hazardous
• area.
• The use of additional batteries whilst in the Ex-hazardous area is
• not permitted.
• Only batteries of type R20 and LR20 according to IEC
• regulations are permitted.
• The use of any other type of battery is strictly forbidden in that it ·
· will invalidate the Ex-Data certification and presents a safety risk.

7. Operating instructions
7.1. Handlamp
Please read through the following operating instructions in order to
help enable the optimisation of all functions of the handlamp type
H-4 DCA.
For your own information and safety please read the advice on the

(with batteries)
and 0,5 Ampere,
Type H-141
7.3. Opening
Warning: Do not open the handlamp within the Ex-hazardous area.
Before opening, switch to OFF. The handlamp head is removed by
turning anticlockwise from the main casing – please note, that as
the handlamp head is fitted with a high integrity seal, this action
14
can be difficult to start. To replace the handlamp head, reverse the
procedure – ensuring that the handlamp head is screwed fully
closed.
7.4. Bulb replacement
With the handlamp head removed the bulb is accessed by unscrewing - in an anticlockwise direction - the bulb retention socket.
Please ensure that only correctly specified bulbs are used.
7.5. Battery replacement
When the battery power is becoming exhausted all of the batteries
should be replaced. Only those batteries of the corresponding permitted types can be used.
With the handlamp head removed the batteries can be accessed
and removed from the cavity of the main casing.
Replace in reverse procedure – ensuring that all the contacts are
clean.
8. Repairs
The general terms and conditions of ELEX V apply to repair work.
The manufacturer must carry out the repair work in order to check
for the safe functioning of the protective circuits.
9. Cleaning
The equipment should only be cleaned using a cloth or sponge
dampened with water. The use of cleaning solutions or scouring
agents is not advised.
