Always isolate the equipment from the supply when fitting a lamp
See next sheets for fitting aid diagram
Before fitting the lamp:
Loosen and remove five M8 socket bolts with the dubo washer on the underneath of the
-
searchlight, then remove the upper hood off the searchlight & store along with the bolts and
washers in a safe area;
After fitting the lamp,
Replace the upper hood, ensuring the groove aligns correctly with the glass gasket replace
-
the bolts and washers and make sure they are securely fastened.
When fitting the lamp:
Always isolate the equipment from the supply when inserting a lamp;
-
Ensure the circuit is suitably fused;
-
Ensure the lamp is of the correct power rating and type;
-
Check the lampholder is in a good dry condition. Never allow water to collect in the lamp
-
fitting or come into contact with the lamp.
To fit the lamp:
Fit the rear lamp holder lead over the thread of the lamp and then screw into the rear lamp

Testing
Upon correct installation and connection to an electrical supply, the equipment can be tested in
order to ensure its' correct performance. A competent person with some knowledge of electrical
equipment must carry out this work.
Equipment required:
Using the equation P=VI, the approximate power output of the equipment can be calculated in
the following way:
Using the multi-meter, take a voltage reading across terminals 4 & 5 inside the junction
-
box;
Using the ammeter, take an amp reading from the cable in terminal 4 inside the junction
-
box;
Multiply these figures together to give an approximate wattage (Power output).
-
For example:
Using a 300w xenon lamp:
Voltage reading = 20v; Amps reading = 15 amps
Therefore, Wattage = 20 x 15 = 300 watts
