Data Collecting Unit - Furuno VR-3000 Installation Manual

1.2 Data Collecting Unit

The DCU is designed for on-deck or bulkhead installation, and should be mounted within the
wheelhouse. Mount it in a place convenient for connection with relevant sensors and associated
devices. For bulkhead mounting, be sure the mounting location is strong enough to support the
weight of the unit under the vibration normally encountered onboard the vessel. Be sure to
mount the DCU in an area with low humidity and away from high temperature materials, as well
as an area with minimal vibration and shock.
Eye bolts are provided at the top of the unit to hoist the unit onboard. Remove them after
installation and plug eye bolt holes with supplied cosmetic caps.
1.2.1 General mounting considerations
Mount the DCU considering the following points.
•
The mounting surface must be flat. If it is not flat, insert a number of washers between the
unit and the mounting surface as necessary.
•
The mounting location should be away from places subject to water splash and rain.
•
Choose the location considering cable lengths, connection of relevant sensors and
associated devices, access to connectors and the unit's door.
•
A magnetic compass will be affected if the DCU is placed too close to a magnetic compass.
Observe the compass safe distances on page ii to prevent deviation of the compass.
•
Observe the recommended service clearances shown in the outline drawing.
