1. MOUNTING
1.1 Network Sounder
1.1.1 Mounting considerations
The network sounder can be installed on the deck or on the bulkhead. When selecting a
mounting location, keep the following points in mind:
•
The temperature and humidity of the mounting location should be moderate and stable.
•
Locate the unit away from exhaust pipes and vents.
•
The mounting location should be well ventilated.
•
Do not install the equipment where it may get wet from rain or water splash.
•
Mount the unit where shock and vibration are minimal.
•
Keep the unit away from electromagnetic field-generating equipment such as motors and
generators.
•
Leave slack in cables for maintenance and servicing ease.
•
For mounting on a bulkhead, be sure the mounting location is strong enough to support
the weight of the unit (5.6 kg, 12.3 lbs) under the continued vibration normally
experienced onboard the vessel.
•
Observe the following compass safe distances to prevent disturbance to a magnetic
compass: standard compass, 1.7 m, steering compass, 1.1 m.
1.1.2 Mounting procedure
