Next you will need to attach the Power Supply Unit (PSU) to the wall directly under
the wall mount bracket. The wall mounted PSU is attached via four fixing points
located on the inside of the casing.
4.2.5 Wiring and transformer layout
Remove the fascia of the PSU by removing the two screws in the front to gain access
to the fixing points on the inside.
* Different models have varying transformers. Picture for illustration purposes only.
Note: End user requirement may need you to rotate the PSU 90 degrees left or
right depending on where the user wants the power switch to be located
Align the rear half of the PSU to be true on the wall then mark the locations for the
fixings. Remove the PSU, drill holes for the fixing points and then move the PSU back
into position and insert appropriate fixings.
Feed the cable from the bottom of the light down through the bottom of its wall
mount bracket and feed the cable into the PSU through one of the grommet knock-
outs. Connect the light and the isolated mains to the correct locations within the
PSU.
Connect the low-voltage cable to the 3-way ‘LEN’ terminal block wired to the low-
voltage output from the transformer.
The power-supply module requires an earthed
230V AC electrical supply fed into it via a switched fused spur.
Fasten the module’s earth-bond wire to the fascia plate’s earth stud and re-attach
the plate of the PSU using the two screws previously removed.
WARNING: this light operates from a low-voltage supply produced by a
transformer in the PSU, fed through the suspension arm. On NO
ACCOUNT should this unit be connected directly to mains electricity.
