1. INSTALLATION
1-18
• Determine the location considering the length of the cable between the transceiver
unit and the antenna unit and the cable between the transceiver unit and the power
supply unit.
• A magnetic compass will be affected if the transceiver 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).
How to mount the transceiver unit
Fix the unit to the mounting location with M8 bolts or

8 coach screws. See the outline
drawing for mounting dimensions.
1.8 Sensor Adapters (option)
Installation considerations
When you select a mounting location, keep in mind the following points:
• Locate the adapter 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.
• Be sure to connect the ground wire (between the earth terminal on chassis and the
ship’s earth).
• Leave sufficient space at the sides and rear of the unit to facilitate maintenance.
• A magnetic compass will be affected if the adapter is placed too close to the mag-
netic compass. Observe the compass safe distances in the SAFETY INSTRUC-
TIONS to prevent interference to a magnetic compass.
• Select the location considering the number of sensor adapters connected.
A maximum of eight MC-3000S can be connected to a sensor network.
A maximum of 10 sensor adapters (MC-3010A/3020D/3030D) can be connected to
a MC-3000S. However, note that five MC-3010A can be connected.
• For the MC-3000S, use a Cat5 cable.
• Select the location so that the length of the cables among the sensor adapters (MC-
3000S, 3010A, 3020D and 3030D) is less than 6 m. If the length is more than 6 m,
the adapters may not work properly.
How to install the sensor adapter
1. Unfasten four pan head screws to remove the cover from the sensor adapter.
2. Fasten four self-tapping screws (

4

20, supplied) to fix the sensor adapter.
3. Reattach the cover.
