Selecting A Location - Raymarine VCM100 Installation Instructions Manual

4.1 Selecting a location

Warning: Potential ignition source
This product is NOT approved for use in
hazardous/flammable atmospheres. Do NOT install in
a hazardous/flammable atmosphere (such as in an
engine room or near fuel tanks).
VCM100 location requirements
When selecting a mounting location it is important to consider a
number of factors.
Ventilation
• Ensure that equipment is mounted in a compartment of suitable
size.
• Ensure that ventilation holes are not obstructed. Allow adequate
separation of equipment.
Mounting surface
Ensure equipment is adequately supported on a secure surface.
Do not mount units or cut holes in places which may damage the
structure of the vessel.
Cables
Ensure the unit is mounted in a location which allows proper routing
and connection of cables:
• Minimum bend radius of 100 mm (3.94 in) unless otherwise stated.
• Use cable supports to prevent stress on connectors.
• The maximum length of cable between the battery and the
VCM100 should not normally exceed 19.6 ft. (6 M). All power
cable lengths should be kept as short as possible.

Water ingress
The VCM100 is splashproof, and suitable for mounting below decks
only.
Electrical interference
Select a location that is far enough away from devices that
may cause interference, such as motors, generators and radio
transmitters/receivers.
Magnetic compass
Mount the VCM100 at least 3 ft (1 m) away from a magnetic
compass.
Power supply
Select a location that is as close as possible to the vessel's DC
power source. This will help to keep cable runs to a minimum.
Radar scanner location requirements
When selecting a location it is important to consider a number of
factors.
Horizontal position
The radar scanner should be positioned as near as possible to your
vessel's centerline.
Height
The radar scanner should normally be mounted as high as practical
above the waterline:
• Mount the scanner above head height out of range of personnel,
to avoid mechanical danger and minimize exposure to
electromagnetic radiation.
• Radar operates at the line-of-sight, so a high mounting position
gives better long range performance.
