Heater Connections
1).
All heater elements are designed to operate on 120 V.A.C.
2).
Switch and supply leads must be sized to accommodate a 10
amp load.
3).
As shown in the appropriate schematic in Figure 2, all heater
elements are connected in parallel.
4).
When installing the interconnecting supply wiring to the trunnion
bolts and the rack, be sure to allow enough slack for both
azimuth and elevation movements of the searchlight head to its
limits.
5).
Connections made to the heater elements at the searchlight
(outside the waterproof junction box) must be suitably protected
from weather and sea conditions.
6).
An appropriate indicator light or switch is recommended to alert
the operator that the heaters are energized. Mount the caution
plate near the switch or indicator light.
7).
To prevent over-heating the searchlight, operate heaters only
when ambient temperature is below freezing.
