5. Connect the
conductors in the
power input cable as
follows:
• Connect the
ground (earth) wire
to the screw
terminal marked
close to the
power terminals.
• Connect the
neutral wire to the
spring-loaded
power terminal
marked
N
• Connect the live
wire to the spring-
loaded power
terminal marked
L1 .
6. If power is to continue to another luminaire, pass power output cable
through a cable gland as described in “ Cable entry ” on page 15 and
prepare the end of the cable for connection. Each spring-loaded terminal
has two holes. One hole now contains a conductor from the input cable
and one is available for a conductor from the output cable. Using the
spare holes, connect the conductors in the power output cable as
described under point 5. above.

If you are supplying luminaires with power from a 3-phase system, the live
conductor in the power input cable that you connect to terminal
L1 will be
one of the phases. Connect one of the remaining phases to terminal L2 and
the last remaining phase to terminal L3 .
To distribute the load evenly over the 3 phases, connect phase 1 to terminal
L1 on one-third of the luminaires in the installation, phase 2 to terminal L1
on one-third of the luminaires, and phase 3 to terminal L1 on the remaining
one-third of the luminaires. Terminals L2 and L3 do not supply power to the
luminaire and are provided simply to allow phase conductors in separate
lengths of power cable to be joined.
To avoid confusion, each time you install a power output cable to take power
to the next luminaire, connect each phase conductor in the power
output
cable to the terminal used for that phase conductor in the power input cable.
