1.5 Distribution Box
The distribution box can be mounted on the deck or on a bulkhead.
Consider the following points when selecting a mounting location.
•
Select a location which is both well ventilated and low in humidity to keep the unit cool.
•
The unit weighs 12 kg. For bulkhead mounting, be sure the mounting location is strong
enough to support the weight under the continued vibration normally encountered on the
vessel.
•
A magnetic compass will be affected if the distribution box is too close. Observe the
compass safe distances to prevent disturbance to the magnetic compass.
Fasten the distribution box with four tapping screws (6X30, supplied).
Refer to the outline drawing at the end of this manual for mounting dimensions.
For bulkhead mounting;
1. Tighten lower tapping screws so there is 5 mm clearance between bottom of screw head
and bulkhead.
2. Screw slots of the unit with the tapping screws tightened at step 1.
3. Fasten the unit with upper tapping screws.
1.6 Terminal Box (option)
The terminal box forms a joint among the display unit, digital indicator, distance indicator and
distribution box. Two digital indicators/distance indicators may be connected by installing an
additional terminal box as follows.
•
A magnetic compass will be affected if the terminal box is too close. Observe the compass
safe distances to prevent disturbance to the magnetic compass.
