1.2 Processor Unit
1.2.1 Mounting considerations
When selecting a mounting location, keep in mind the following points:
∙The processor unit must be mounted horizontally.
∙DO NOT place any item on the top of the processor unit.
∙Locate the unit out of direct sunlight and away from heat sources because of heat that can build up inside the cabinet.
∙Locate the equipment away from places subject to water splash and rain.
∙Be sure the mounting location is strong enough to support the weight of the unit under the continued vibration which is normally experienced on the ship. If necessary reinforce the mounting location.
∙Determine the mounting location considering the length of the following cables:
a)Signal cable from the antenna unit
b)Power cable from the ship's mains
c)Monitor cable from the monitor
d)Control cable from the control unit
∙Leave sufficient space on the sides and rear of the unit to facilitate maintenance. Also, leave a foot or so of "service loop" in cables behind the unit for servicing ease.
∙A magnetic will be adversely affected if placed too close to the processor unit. Observe the following compass safety distances to prevent deviation of a magnetic compass: Standard compass, 1.70 m, Steering compass, 0.90 m.
