Part 1. Site Requirements

When planning the installation of the DCS system, choose a site that meets the following require-
ments:
•
Select a location for the key service unit (KSU) that has enough space for easy installation and
has adequate lighting (Figure 1–1).
•
Select a location that minimises cable lengths. See the Cable Requirements table below.
•
The equipment should not be exposed to direct sunlight, corrosive fumes, dust, constant vibration
or strong magnetic fields such as those generated by motors and copying machines.
•
A direct commercial AC power outlet is required. Do not use extension cords. Preferably, a dedi-
cated circuit should be used to minimise the risk of other electrical equipment being connected
that could adversely affect system operation.
•
Ensure that all wires and cables going to and coming from the KSU are properly routed. Do not
cross fluorescent lights or run parallel with AC wires.
•
The equipment must be located in an environment that will maintain a temperature range of 0° –
40°C and a humidity range of 10%–90% non-condensing.
•
Allow at least 150 mm clearance on both sides and 150 mm clearance on top of the KSU to en-
sure proper ventilation.
•
Do not install within a 2-mile radius of a broadcasting antenna or in close proximity to a fire
sprinkler head or other source of water.
Meeting these requirements will help to ensure proper performance and greater life expectancy of the
system.
