2.3 Selecting the Equipment Location
Display Unit Mounting Location
The display unit can be mounted using the mounting bracket supplied or
console mounted using the optional flush-mounting kit. The dimensions of the
display units, including the bracket, are shown below in
Figure 2-3 and
Figure 2-4 .
When planning the installation, the following should be considered to ensure
reliable and trouble free operation:
• Convenience: The contrast and colors seen on all LCD displays vary
slightly with viewing angle; this is more noticeable on the left hand side.
Power the unit and select a suitable mounting location prior to installing
the display. 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 3 ft (1m) away from a
magnetic compass.
• Cable runs: The display unit must be located near a DC power source. The
power cable supplied is 4.9 ft (1.5m), but a longer cable can be used if
desired. Refer to
Section 2.4 .
The maximum length of cable between a display and the transducer unit
should not normally exceed 30 ft (10 m). If you need to use a longer cable,
refer to
Section 2.4.
• Environment: Do not restrict airflow at the rear of the display unit.
The display incorporates Cold Cathode Florescent Lamps (CCFL),
which have a reduced light output when the unit is very hot. Ventila-
tion is required to prevent the unit from overheating.
The display should be protected from physical damage and excessive
vibration. Mount the display in a protected area away from prolonged and
direct exposure to rain and salt spray.
