98 HSB Series Chartplotter
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 and generators
(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, but a longer cable can be
used if required: refer
Section 6.6 Cable Runs
.
• 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.
