FITTING OR REPLACING LED STRIPS OR DAMAGED LAMPLGLASS ASSEMBLIES
1. Remove all eight socket head cap screws from the front of the unit. The hinged lampglass assembly
can then be opened.
2. The LED strips and/or driver assembly can be removed by disconnecting the cables from terminal
block and from the push on terminals on the driver assembly. Remove the retaining screws.
3. Replace the LED strips and/or driver assembly. Fasten in place with the retaining screws and
washers. Connect the cables to the terminal block ensuring all terminal screws are fully tightened
down. Connect the cables from the LED strips to the push on terminals on the driver assembly
ensuring correct polarity.
4. If the lampglass assembly is to be replaced, remove the hinge screws. Replacement is the reversal of
this procedure.
5. Ensure O ring is fitted in place and apply a thin coating of a non-setting grease ( silicone ) to the FLP
surfaces before closing the lampglass assembly.
6. Re-fit all eight socket head cap screws and washers. Fully tighten down all screws.
MAINTENANCE AND INSPECTION.
Frequency of inspection must be determined by the installer, but should be frequent enough to ensure that the
luminaires continue to work in their designed manner. The more onerous the working conditions, the more
frequent the inspection. The interval should never exceed two years.
The following list indicates some of the points that should be given particular attention. Suitable repairs should
be carried out if required:-
a) Clean all flameproof paths using a non-metallic or suitable non-corrosive cleaner and examine the
flameproof paths for signs of damage. Replace damaged parts.
b) Dirty lampglass should be cleaned.
c) Replace cracked or damaged lampglass assemblies.
d) Replace any missing fasteners with items of the correct type and quality.
e) Fit new gaskets, lock-washers, etc as appropriate.
f) Grease all flamepaths and screw threads with a non-setting grease (e.g. silicone )
g) Ensure that blind tapped holes are clear of dirt, etc that could prevent correct closure of joints.
h) Do not over-tighten fasteners on re-assembly.
i) Ensure all mountings are secure and not corroded.
j) Check cable glands for tightness and check the luminaire is efficiently earthed.
k) Check resined joints for deterioration. If damaged then the assembly must be replaced in its entirety.
Resined components cannot be repaired except by the manufacturer.
l) Any mechanically damaged parts must be replaced.
m) A list of spares can be obtained from the manufacturer.
GENERAL
All components that are replaced should be in accordance with the manufacturer’s specification. Failure to use
approved parts invalidates the certification and approval of the luminaire and may make it dangerous.
