4.5.2 Procedure
1. UEL-1-150 steady burning light
The following table instructs you on how to install the UEL-1-150 on a 60 mm O.D. conduit:
a) Before installing the light, prepare a two-core cable with plug, making sure that a sufficient length of cable is available
above the conduit elbow or cover plate. Connect the plug of the two-core cable to the receptacle of the cable coming
from the transformer.
Note
The transformer receptacle rests in the upper part of the conduit elbow or the cover plate.
CAUTION
Do not tape the plug/receptacle assembly in order to allow for quick disconnection in case of impact.
b) Install the breakable coupling on the conduit elbow or cover plate, and the conduit on the breakable coupling.
CAUTION
Make sure that the conduit is perfectly vertical, using the screws of the breakable coupling for adjustment.
Tighten the counter-nuts.
c) Remove the optical cartridge (1) 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 the conduit,
without tightening the bracing clamp (5).
d) Clamp the cable into the stress reliever (6).
Note
In case of a top light, the two cables should be clamped into the cable stress reliever.
e) 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.
f) Adjust the position of the light unit, see §
Orientation and elevation settings
.
g) Once the position of the light is correct, put the optical cartridge back in place.
h) 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.
i) Close the light fitting.
2. UEL-1-120 flashing light
The following table instructs you on how to install the UEL-1-120 on a 60 mm O.D. conduit:
a) Before installing the light, make sure that a sufficient length of 5-core cable coming from the FCU cabinet is available
above the conduit elbow.
b) Install the breakable coupling on the conduit elbow or cover plate, and the conduit on the breakable coupling.
WARNING
The conduit must be perfectly vertical, using the screws of the breakable coupling for adjustment. Tighten the
counter-nuts.
