LUMINAIRE INSTALLATION
1. Remove diffuser by unscrewing the two screws.
2. Hinge the gear tray open by pushing apart the two retaining clips.
3. Screw fix the base to the chosen mounting surface using the two
screw fixing points in the base moulding at 240mm centres. These
should be drilled to a size to suit the fixing screws.
Note: It is responsibility of the installer to ensure these fixing
points are sealed to ensure the IP65 rating is maintained. The
use of a silicone sealant is recommended.
4. Select one of the available cable entry points on the base (one on
either end, on one side, or through the bottom) & drill to suitable size
to suit IP65 rated (or better) cable entry gland (not provided).
5. Install cable entry gland.
6. Depending on which variant of the product you have, determine your required function & route the appropriate power
supply cable to the terminal block & terminate as shown.

off M4 screws aligned with the tapped holes on the brackets of the frame.
