1.5.2 How to install the power supply unit
Use four bolts (M6, local supply) to fix the
power supply unit.
Note: For bulkhead mounting, the open
notches on the unit must face the deck.
1.6 Processor Unit
1.6.1 Installation considerations
Keep in mind the following points when selecting a location.
• Locate the processor unit away from heat sources because of heat that can build
up inside the cabinet.
• Select a location where the vibration is minimal.
• Locate the equipment away from places subject to water splash and rain.
• Make the service clearance of 100 mm in front of the vent hole (left side).
• Leave sufficient space at the sides and rear of the unit to facilitate maintenance.
• Be sure to connect the ground wire (between the earth terminal on the chassis and
the ship’s earth).
• A magnetic compass will be affected if the processor unit is placed too close to the
magnetic compass. Observe the compass safe distances in the SAFETY IN-
STRUCTIONS to prevent interference to a magnetic compass.
• Leave the dummy plate fastened, to prevent the wrong operation of the power
switch. The items behind the plate are for use by the serviceman.
