1.2 How to Install the Junction Box (SC-701)
The junction box can be mounted on the floor, bulkhead, on a desk/console or on the
underside of a desk.
Mounting considerations
Select a mounting location, keeping the following points in mind:
• Locate the SC-701 away from heat sources. Heat can build up inside the unit, caus-
ing damage to electrical parts.
• Locate the SC-701 away from areas prone to vibrations. The mounting location
should have minimal vibrations.
• Locate the SC-701 away from areas prone to water splash and rain.
• Make sure to connect the unit’s ground to the ship’s ground.
• Leave sufficient space around the unit to allow access for maintenance. See the
outline drawings at the back of this manual for the recommended maintenance
space.
• A magnetic compass will be affected if the junction box is placed too close to the
magnetic compass. Refer to the compass safe distances at the front of this manual
when selecting a mounting location.
• The power switch has a small light which lights up when the unit is turned on.
Note 1: For wall/bulkhead mounted junction boxes, the cabling entrance indicated in
the figure below must be oriented to face downwards, to avoid water entering the unit.
Note 2: For floor/desk mounted (top or bottom) junction boxes, select a location where
water will not reach the cabling entrance indicated in the figure below.
1. Referring to the outline drawing at the back of this manual, drill four pilot holes for
the fixing screws.
2. Fasten two self-tapping screws (I20, supplied) at the location for the top fixing
holes. Leave approximately 5 mm of thread exposed.
3. Hang the SC-701 on the two screws using the two top fixing holes.
4. Fasten two self-tapping screws (I20, supplied) to the bottom fixing holes.
5. Fasten all screws to secure the SC-701 in place.
