Before proceeding with installation or service, make sure the following conditions are met:
•
Check the lighting circuit is safe

Ensure power lines are not 'live' (NO ELECTRICAL HAZARD)
•
Avoid touching live circuits!
•
Avoid touching any component or any part of the circuitry while the unit is operating. Do not
make adjustments to the unit or wiring with the power on.
ELECTRICAL INSPECTION AND TEST
The inset light is manufactured with a 3 core input fly lead, of default length. One end of the input
cable is molded into the light fixture and the other end is terminated with colour coded ferrules. Refer
to the table below for details on each conductor and their function.
Ferrule Color Coding
To test the light fixture, connect a 24VDC source to the two input power wires in accordance with table
above and apply power, this should result in the light turning on at full (100%) intensity. If dimming
is required, connect a variable 0-10VDC source to the remaining conductor. Dimming occurs in
accordance with the following table.
