Caution
Do not allow anything to be placed upon the power supply case; the perforated top is for
ventilation and must not be obstructed.
Try to select a location as close to the lamphouse as practical. Many users install the power supply
adjacent to the searchlight where space is available and local codes permit.

the unit. Turn off all power when adjusting or servicing the power supply.
