c. Power Supply and General Electrical Installation.
WARNING
The Power Supply and optical assembly contain very high voltage and current which
are hazardous to human life. Extreme caution must be exercised when
servicing the XR Series 500 watt marine searchlight. Prior to performing any service
on this part, turn circuit breaker off. Open access door and wait a minimum
of 30 seconds before attempting service.
WARNING
The Power Supply unit is heavy and should be handled and installed
by two or more persons.
(1) The Power Supply for the XR Series Model 9304 500 Watt xenon searchlight is supplied in a
NEMA electrical enclosure measuring 20-1/4 inches high by 16-1/4 inches wide by 9-1/4 inches deep.
Three inches minimum should be allowed around the two ends and the back for adequate ventilation. 30
inches should be allowed in front of the Power Supply to allow service personnel adequate access to the
interior components and necessary service.
(2) The Power Supply should be mounted in a location protected from weather, approximately 24
to 36 inches above the floor. In any event, it should be mounted no nearer than 6 inches to the floor. The
Power Supply should be attached to its mounting surface with four 3/8 inch bolts through the four corner
holes provided in the Power Supply cabinet.
(3) Figure 2-1 shows the 115 VAC Power Supply connection requirements. Install a disconnect near
the Power Supply to disconnect the ship’s power from the searchlight Power Supply. This is a safety
requirement since power to the Power Supply is not disconnected when the Power Supply door is opened.
Prepare and install a 3 conductor power cable from the customer supplied disconnect to the Power
Supply (hot to Terminal 1 of TB3. neutral to Terminal 2 of TB3, and ground to the enclosure”.
