Mounting 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.
• The vibration should be minimal.
• Locate the equipment away from places subject to water splash and rain.
• Make sure that the ground wire is connected 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 at the front of this manual to
prevent interference to a magnetic compass.
• Select the mounting location considering the numbers of the sensor adapters con-
nected.
Maximum eight MC-3000S can be connected to a sensor network.
Maximum 10 sensor adapters (MC-3010A/3020D/3030D) can be connected to a
MC-3000S. However, note that five MC-3010A can be connected.
• Select the mounting location so that the length of 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 equipment may not work properly.

1. Unfasten a pan head screws to remove the cover from the sensor adapter.
