Connecting via separate power and data cables

Connecting to power
To connect the fixture to AC mains power you must use correctly dimensioned cable that is suitable for
the installation environment (with regard to UV resistance, weatherproofing, temperature rating etc.)
and that has an external diameter of 8–12 mm (0.32–0.47 in.).
To connect to AC mains power in a single-phase system or using one phase of a three-phase, four-
wire system:
1. Lock out power to the installation.
2. Strip approximately 50 mm (2 inches) of the power cable's outer jacket. Strip approximately
12 mm (half an inch) of insulation from each of the three wires in the cable. Crimp a ferrule onto
the end of each wire. The ferrules must be long enough to pass fully into the terminals but there
must be no exposed metal outside the terminals.
3. See illustration below. Release the four Allen screws in the connections compartment cover on the
back of the fixture and remove the cover. Loosen the compression nut A on the cable gland shown
and remove the sealing plug B from the gland. Pass the power cable through the cable gland.
4. See illustration on right:
a) Loosen the two
screws (arrowed) in
the detachable
mains power
terminal block and
remove the block
from its base inside
the fixture.
b) Fasten the green
wire (US system) or
yellow/green wire
(EU system) into the terminal marked
c) Fasten the white wire (US system) or blue wire (EU system) into the terminal marked N
(neutral).
d) Fasten the black wire (US system) or brown wire (EU system) into the terminal marked L (live
or one phase of a three-phase system).
e) Re-insert the detachable mains power terminal block into its base and fasten it in place with its
two screws.
5. Either continue installation work by connecting the data cable as described later in this chapter or
re-install the connections compartment cover, checking that the seal in the back of the fixture is
clean, dry and in perfect condition.
