Seals and cable glands

To maintain the luminaire’s resistance to dust and moisture, it is important to replace
silicone seals carefully after removal. The seals should maintain their sealing ability for the
life of the luminaire, but examine them when servicing the luminaire and replace any seal
that is cracked, torn, brittle, or inflexible. Replacement seals may be ordered from Martin
Architectural. For part numbers, see Table 3 on page 62.
The seals must extend 0.5 - 1 mm (1/64 - 1/32 in.) beyond the outside of the casing. If you
can feel the seal when you run a finger across the joint, that’s enough. Seals will be
effective if they are flush with casings, but if they are below the casing’s edge, they can
collapse into the luminaire and let water in.
The recommended procedure for closing all covers is the same:
1. Ensure that the seal and mating surfaces are clean.
2. Place the cover and seal firmly against the housing. Adjust the straight sides of the
seal so that they stick out a little, just enough so that you can feel the edge of the seal
when you run a finger across the joint.
3. Cross-tighten (i.e. tighten diagonally) retaining screws gradually and evenly to the
torque settings specified in Table 3 on page 62.

Provision is made for cables to enter the luminaire through IP68-rated cable glands that
accept:
• power cable with an external diameter of 8 - 13 mm (0.32 - 0.5 in.) and
• data cable with an external diameter of 5.5 - 10 mm (0.22 - 0.39 in.)
The cable glands must be replaced with suitably dimensioned items if the diameter of
cable used is not within this range.
Replacement glands, available from electrical suppliers, must have the following
characteristics:
Temperature range
-20° to +90° C (-4° to 194° F) or better
Ingress protection rating
IP67 minimum
Minimum entry thread
length
8 mm
