Maintenance must only be carried out in a safe area and with the supply
disconnected
Repairs, maintenance and bulb changing only to be undertaken in a by trained personnel to the
requirements of EN60079-14, Electrical installations in hazardous areas (other than mines) and EN60079-17
Inspection and maintenance of electrical installations in hazardous areas (other than mines) .
To replace the bulb
Ensure that the bulb has cooled. Remove the lock screw on the front face of the lamp lens ring, the screw
can be seen through hole in hexagonal rubber shroud.
The rubber shroud and lens ring assembly complete can then be unscrewed from the leadlamp body in an
anti clockwise direction. Care must be taken not to damage the threads on the lens assembly as this is the
critical joint of the flameproof enclosure. There is a screw securing the bulb to the bulb holder, remove screw
and disconnect the male spade terminal from the switch wire. Replace with correctly rated bulb and re-
assemble.
To replace the reflector
Remove the lens assembly by undoing the wire clip on the outside diameter of the reflector. Caution, the
spring is under tension and may recoil with some force. Safety glasses should be worn. Please note the
glass lens cannot be replaced as this is permanently set into the lens ring.
Assembly is the reverse of the above, ensure threads are not crossed and the sealing “O” ring is fitted.
Switch replacement
To replace the switch remove lens assembly as above, unscrew switch plate securing screws (x2) and de
solder wire connections. Note which terminals are connected to which wire. The switch actuating rod can be
taken out when the circlip on the end of the shaft is removed. Ensure the “O” ring on the shaft is in good
condition. There should be no sign of wear on either the bore or the shaft.
Fitting / Replacement of Cable
Remove the two screws on the cable clamp on the Ex cable entry gland. Unscrew the cable clamp (small
hexagonal nut) from the gland body, to loosen the rubber-sealing washer, so that cable can be pulled
through. The gland does not need to be disassembled.
Unscrew the three socket screws securing the handle. Slide handle back over cable. The Increased Safety
cable terminals are now accessible to fit the cable. Replacement cable MUST be suitable for the operating
voltage / current and for the environment it is to be used in. Assembly is reverse of above. Ensure cable
gland seal is in good condition. Do not over tighten socket screws for the handle this may distort and stress
the moulding.

The Flameproof Lead Lamp meets all relevant provisions of the 2014/34/EU (ATEX Equipment) Directive.
The lamp output is a bright focused halogen beam powered from 12V, 24V or 42V AC/DC, depending on model.
The lamp housing is made of aluminium alloy, the handle is made from high impact thermoset plastic. It is fitted
with a protective glass lens and a hexagon rubber shroud guards it against impact damage. The lamp is supplied
complete with leather carrying strap and a bulb. Cable can be supplied on request.
The Lamp can be used in Zone 1 and 2 Hazardous Areas for inspection, maintenance, cleaning and other work
tasks and in association with shot blasting and recoating of tanks, boilers, pressure vessels and silos.
Copies of BVS Certificate number BVS03ATEXE279 are available upon request.
Users and Maintainers should consult EN60079 Selection and Installation of Electrical Apparatus for use in
potentially explosive atmospheres, and classification of industrial Hazardous Areas.
If a lamp becomes damaged, it should be withdrawn from service and thoroughly checked over, and repaired, as
necessary before being put back into service.
Maintenance and Repair must only be carried out by a competent technician or electrician familiar with Certified
Electrical Apparatus in accordance with European guidelines EN60079-17 codes of practice and these
maintenance instructions, using only factory supplied spare parts.
LAMPS MUST NOT BE OPENED IN A HAZARDOUS AREA.
All maintenance activities must be carried out in a safe non-hazardous area.
