3.3.2 Interconnected Chassis Installed in Rack or Cabinet
Systems mounted in racks or cabinets at the factory are to be placed in position and then bolted
to the floor or wall, as appropriate, to secure the equipment in place. The type of hardware used
will depend upon the surface type to which the rack or cabinet is being mounted. Because of this,
mounting hardware is not supplied with the rack or cabinet.
3.3.3 Interconnected Chassis Mounted on Shipping Rails
For delivery, equipment is mounted on shipping rails. To remove the shipping rails and mount
the equipment in a rack or cabinet, proceed as follows:
1.
Place the equipment as close to the front of the rack or cabinet as possible, with the rear
panels of the equipment facing the front of the rack or cabinet.
2.
Remove all the screws securing the shipping rails to the equipment.
3.
Slide the equipment into the rack or cabinet.
4.
Install and tighten screws to all panels to secure the equipment in place.

Ventilation
The specified operating temperature range for HPS/RFL GARD Pro system equipment is -20
o
C
to +70
o
C (-4
o
F to +158
o
F). Operation at higher temperatures may affect system reliability and
performance. Systems installed in enclosed cabinets should be ventilated to keep the temperature
inside the cabinet within limits.
CAUTION
Improper wiring can cause false trips
Normal system operation switching of relay contacts can produce voltage spikes. These spikes
can travel down the relay output leads and induce currents in other leads. These induced
currents can result in false trips. To reduce this possibility, use a shielded twisted pair for each
input lead, and ground the shield at the HPS/RFL GARD Pro system chassis
only.
As an added
precaution
,
do not bundle input, output, and power leads into the same harness, and keep them
as far apart as possible.
