Selecting The Display Unit Site - Raymarine RL70C Owner's Handbook Manual

Chapter 8: Installation

8.3 Selecting the Display Unit Site

The display unit can be mounted using the trunnion (yoke) bracket already
fitted, or console mounted using the optional flush-mounting kit.
The dimensions of the display unit, including the bracket, are shown in the
following diagram.
When planning the installation of your display unit, the following points should
be considered to ensure reliable and trouble free operation:
• Convenience: The display unit should be installed in a convenient position,
where it can be viewed straight on or with a viewing angle of less than 35°.
You may wish to apply power before you install the display unit, to
determine the best viewing angle prior to fixing.
The mounting location should be easily accessible to allow operation of the
front panel controls.
• Access: There must be sufficient space behind the display to allow cable
connections to the rear panel connectors, avoiding tight bends in the cable.
• Interference: The selected location should be far enough away from devices
that may cause interference, such as motors, generators and radio transmitter/
receivers (see the EMC guidelines earlier in this section).
• Magnetic compass: Mount the display unit at least 1m away from a
magnetic compass.
• Cable runs: The display unit must be located near a DC power source. The
power cable supplied is 1.5m (4.9 ft), but a longer cable can be used if
required: refer to Section 8.4 Cable Runs.
The maximum length of cable between a master display and the scanner unit
should not normally exceed 20 m (60 ft). If you need to use a longer cable,
refer to the Pathfinder Radar Scanner Owner's Handbook.
• Environment: Do not restrict airflow at the rear of the display unit;
ventilation is required at the rear to prevent the unit overheating.
The display should be protected from physical damage and excessive
vibration. Although the display is waterproof, it is good practice to mount it
in a protected area away from prolonged and direct exposure to rain and salt
spray.
