5 - Electrical Installation
Note: ~
When the main power is first applied to the searchlight, the searchlight will carry out a
self-test, it will Pan to the left limit and Tilt down to the limit, once this is complete, the
searchlight will then move to the centre and horizontal, during this please do not try and
operate the searchlight while this test is being carried out. Once the searchlight is back
at centre the searchlight can then be operated normally, by pressing the Panel button on
the control panel.
For safety purposes, only competent personnel should perform the electrical installation. All
equipment should be installed to current Electrical Regulations and Standards.
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 mains supply, provision must
be made in the cable size to overcome the voltage drop.
The following table below indicates the maximum length of cable to be used for the 3
phase 440v AC supply cable to the PSU:
Searchlight 440v 5Kw
Cable Size (mm²) Distance Max
1.5 71 MTRS
2.5 120 MTRS
4 192 MTRS
6 286 MTRS
10 505 MTRS
4) Whenever possible cable terminations should be made below deck and with approved
terminal devices.
5) If a spare auxiliary fuse or circuit breaker is not available, one of the correct type/ratings
should be fitted and connected to a positive supply. It is advisable to locate a bus bar or
main connection and avoid any direct connection to the supply:
6) For AC products, the following colour coding system should be used for the customer
supply cable:
Brown - Live
Blue - Negative
Green/Yellow - Earth
Note: This equipment must be earthed.
