3-2 Installation
• Check that the temperatures within the vicinity of the units are
between -10 to 50 degree C (14 to 122 degree F). In case of
8720MC-RPS190, however, the ambient temperature must be
between -10 to 40 degree C (14 to 104 degree F).
• Check that the relative humidity is between 5 and 95% without
condensation.
• Do not install the units above 1,000 meters (3,300 feet) without
derating output power. For every 300 meters (1,000 feet) above
1,000 meters (3,300 feet), derate the output power 4%. When
you need to install the units above 1,500 meters (5,000 feet),
contact The Allen-Bradley Company.
In case of Model 8720MC-RPS190BM and 8720MC-RPS190BS,
it is possible to ship the units from the factory after mounting each
of these units in a cabinet together with the required peripheral
devices and installing wiring in the cabinet. When the user
purchases from The Allen-Bradley Company the units mounted in
the cabinet, the above-mentioned guidelines should be considered
for selection of the installation site.
Required Total Area
Overall unit dimensions are shown in Figures 3.1 and 3.2. Figure
3.1 illustrates the dimensions of Model 8720MC-RPS027 and
8720MC-RPS065 units, and Figure 3.2 shows the outline
dimensions of 8720MC-RPS190 unit. Also as an aid in calculating
the required total area, Figures 3.3 and 3.4 show the required
distance between two adjacent units in case of two or three
paralleled units of Model 8720MC-RPS027 and 8720MC-RPS065,
and Figures 3.5 and 3.6 show the required distance between two
adjacent units in case of two or three paralleled units of Model
8720MC-RPS190 unit installed in a cabinet provided by the user.
