3. Check that all installation work is completed and carry out appropriate tests and safety checks before
applying power.
Replacing the power cable
If you replace the supplied power cable, the new
cable must be listed, adequately dimensioned for the
current requirements and suitable for the installation
environment, particularly with regard to water,
pollution, thermal and UV resistance. Use Hypalon
or neoprene rubber-jacket cable rated to 90° C (194°
F) minimum. The conductor size must be 1.5 mm
2
or
16 AWG minimum.
To install a new power cable:
1. Lock out power to the installation and allow the
fixture to cool for at least 20 minutes.
2. Loosen the dome nut in the power cable gland
and then unscrew the gland from the rear cover.
3. See Figure 8. Remove the rear cover retaining
screws (arrowed) and remove the rear cover.
4. Disconnect the existing cable from the power
terminals, then remove it together with the old
cable gland.
5. Pass the new cable through a new cable gland
and through the rear cover.
6. See Figure 9. Connect the
conductors in the new cable to the
spring-loaded power terminals in
the rear cover as follows:
- Connect the ground (earth) wire
to the terminal marked
- If using a
single-phase system
,
connect the power cable’s neutral
wire to terminal
N
and connect
the power cable’s live wire to
terminal
L
.
Important! Do not
connect the live wire to
terminal L2 as there is
electrical continuity between
this terminal and terminal N
(see Figure 10).
