The following table instructs you on how to install the UEL-1-150 on a safety approach mast:
a) Before installing the light, install a two-core secondary cable from the transformer to the top of the mast, according to
the instructions of the manufacturer of the mast.
CAUTION
Make sure to provide sufficient slack in the cable so as to cope with possible height adjustment of the mast.
b) Lower the mast.
Remove the optical cartridge by hinging it down and lifting it out of the hinge.
Insert the two-core cable through the housing (3), and install the light without optical cartridge on top of the mast,
without tightening the bracing clamp.
c) Clamp the cable into the stress reliever.
Note
In case of a top light, the two cables should be clamped into the cable stress reliever.
d) Cut the two-core cable in the light fitting to the right length, maintaining sufficient slack to easily connect it to the
lamp with the cartridge hinged down.
Crimp the "fast-on" connectors on the cores of the cable.
Slip the insulation sleeves over the cores of the cable.
e) Adjust the position of the light unit as described in §
Orientation and elevation settings
f) Once the position of the light is correct, put the optical cartridge back in place.
g) Connect the lamp to the fast-on connectors.
CAUTION
To avoid short-circuits, make sure to slip the insulation sleeves over the fast-on connectors .
h) Close the light fitting.
