5.3 Location
This section provides information affecting the possible location of the unit for
ease of use, access for servicing and its position relative to the power supply.
Selecting the best location
The unit can be mounted using the trunnion (yoke) bracket, or panel mounted
using the optional Panel Mounting Kit.
When planning the installation of your RayChart 420, the following points
should be considered to ensure reliable and trouble free operation:
Convenience: The 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 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 unit to allow cable
connections to the rear panel connectors, avoiding tight bends in the cable.
At least 4cm should be allowed at the right to enable chart cards to be
inserted and removed.
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).
Cable runs: The 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. Power must
be supplied via a 1A quick blow fuse or circuit breaker. Refer to Section 5.6
Cabling.
