1. INSTALLATION
1-13
1.4 Control Unit
The control units can be installed on a desktop or flush mounted in a console. For the
desktop installation the unit can laid flat or tilted.
Installation considerations
Keep in mind the following points when selecting a location.
• Select a location where the control unit can be operated easily.
• Locate the unit 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.
• Leave sufficient space for maintenance and service, referring to the outline draw-
ings at the back of this manual.
Note: The outline drawing number for RCU-024 and RCU-025 is different depend-
ing on the serial number, as shown below:
For RCU-024:
• “199999” or earlier: See “C4473-G02” to “C4473-G04”.
• “200001” or later: See “C4473-G18” to “C4473-G20”.
For RCU-025:
• “199999” or earlier: See “C3607-G01” to “C3607-G03”.
• “200001” or later: See “C3607-G05” to “C3607-G07”.
• Determine the location considering the length of the signal cable between the con-
trol unit and the processor unit.
• A magnetic compass will be affected if the control unit is placed too close to the
magnetic compass. Observe the compass safe distances in the SAFETY IN-
STRUCTIONS to prevent interference to the compass.
• Be sure to connect the ground wire (between the earth terminal on the chassis and
the ship’s earth).
• Fasten the USB cable with the cable
tie.
