5 - Electrical Installation
For safety purposes, only competent personnel should perform the electrical installation. All
equipment should be installed to current Electrical Regulations and Standards.
In order to obtain the maximum light output from the searchlight, it is essential that the full
operating voltage of the lamp fitted be applied to the lampholder contacts.
Method of Electrical Connection
1)
Disconnect the supply before working on the electrical system;
2)
The searchlight must be connected to a fused electrical supply, using suitably sized cable;
3)
If the searchlight is located a considerable distance from the supply, provision must be made in
the cable size in order to overcome the voltage drop.
The Control Gear should NOT be positioned no more then 5 meters away from the
Searchlight.
The following table below indicates the maximum length of cable to be used for the AC supply
cable, from the supply to the searchlight:
