Electrical installation
Install the electrical wiring according to the wiring diagrams showing at pages 11 - 14. Keep the distance
between the power supply and halogen lamp as short as possible. Long wires will increase a voltage drop
near the halogen lamp, which affects the light output.
Cable glands
ØD
Preferred cable diameter D is 7 - 12 mm
Cable too tight!
This gives unwanted stress at the sealing of the
cable gland and water ingress will occur.
Include cable slack at the entering
point of the cable gland
Replacing cable gland
• Use gasket between housing
and cable gland
• Tighten firmly (6Nm) with
wrench
Remove the plug before placing the cable.
If no cable is connected leave the plug in place!
Note
The cable glands on the searchlight prevent water ingress. Do not use (electrical) tape to cover the
cable where it enters the cable gland as this will cause water ingress. Do not use a rubber or shrink-
able cover on the cable gland to improve water tightness.
