DANGER! Fuseholders remain live even if the MAINS switch is set to off. Cut
power to the luminaire before changing a fuse.
To gain access to the connections compartment:
1. If the luminaire has been in use, allow it to
cool completely.
2. If you intend to open a main fuseholder, cut
AC power to the luminaire and ensure that
power cannot be reapplied accidentally by
locking it out.
3. See Figure 6. Loosen the screws in the rear
cover plate and carefully remove the plate
and seal.
4. If you intend to alter any connections, shut
down AC power by setting the MAINS switch
to 0 (off). Before you touch any connectors,
use a tester to check that they are not live.
After access to the connections compartment:
1. Check the condition of the rear cover seal. Replace with a new item if the seal is torn,
cracked or brittle.
2. Hold the rear cover plate and seal firmly against the luminaire housing. Adjust the
sides of the seal so that the seal sticks out a little, just enough so that you can feel the
seal when you run a finger across the joint.
3. Cross-tighten the cover plate screws gradually and evenly to 2 Nm (1.5 ft.-lbs.). At this
torque, the seal will be compressed by about one-third and will be waterproof to IP65.
