INSTALLATION SEQUENCE
It is recommended that the fitting is
assembled prior to screwing to the top of the
post.
Housing Assembly
1. Remove the fitting from the
packaging (be careful separating the
cardboard inserts as the driver
housing sits loose inside).
2. Connect the two pole plugs.(Fig. 6,
Step 3)
3. Attach the driver housing to the lamp
housing. Ensure the gasket seal is
free from dirt and debris prior to
tightening the M6 screws to a torque
of 2Nm. Make sure the rubber o-
rings are attached to each
screw.(Fig. 6, Step 4/5)
Wiring
4. Strip back supply cable (not
included) as shown. Cores should
be 1.5-2.5mm

5. Feed cable through gland, push live
and neutral wires into the screw
terminals and tighten.(Fig.3)
6. Snap terminal plug into gland before
tightening around cable.(Fig.4)
7. Connect the mains flex connector to
the driver housing connector and
secure using bayonet feature.(Fig.5)
Mounting to column
8. Pull the mains flex and connector
out of the base of the driver housing.
(Fig. 6, Step 1)
9. The housing comes with an insert for
a 60mm diameter post which should
be in place and fixed with the M6 x
24mm grub / blind set screws.(Fig.7)
10. For a 76mm pole remove the insert,
taking care not to lose the nuts that
the screws fasten to (these are not
held captive in the housing) and re-
fit with the M6 x 16mm screws. For
each variant screws should be
tightened to a torque of 6Nm.(Fig.7)
Specification
If the product is to be
installed on fibreglass
poles, the LED circuit can
develop very high electrical
potential that would
damage the luminaire.
Therefore in this case it is
recommended to carry out
equipotential bonding
between the fixture’s metal
frame and the ground
terminal.
