QCA RPE CABINET INSTALLATION
STEP PROCEDURE
1 Transport the cabinet as close as possible to its final location.
2 Transport the remaining equipment to a convenient safe dry location.
3 Unpack and inspect the cabinet.
4 Remove cabinet from pallet and place on floor.
5 If casters are provided, tilt the cabinet and replace the levellers on the cabinet with four
casters.
6 Adjust floor levellers or casters when in final location. When casters are provided,
ensure that they are locked in position when the cabinet is in its final location.
7 Remove the front and rear cabinet covers.
8 If required, install additional shelves as described in Chart 2-2.
9 Install but do not connect a 6 AWG wire between the approved building ground and
the ground lug identified by a ground symbol (Fig. 2-1) at the rear of the cabinet.
10 At the building ground end of the wire, connect the 6 AWG wire to the approved
building using at least two fastening devices and insulate the connections with
electrical tape. Install a DO NOT DISCONNECT tag on the connection.
11 With an ohmmeter, measure the resistance between the ground pin on the ac power
cord plug and the ground lug at the rear of the cabinet (Fig. 2-1). The resistance should
be
0 . If greater than 0 , check power cord connections at rear of cabinet.
12 Ensure that the AC BRKR breaker on the faceplate of the -48 V rectifier in the cabinet
is set to OFF.
13 Connect the power line cord to the commercial ac power supply.
14 Measure the resistance between the system ground wire and the ground lug at the rear
of the cabinet (Fig. 2-1). If the resistance is greater than 5 , check the building ground
and ac panel connections.
15 Disconnect the power line cord from the commercial ac power supply.
16 Connect the 6 AWG building ground wire to the ground lug identified by a ground
symbol at the rear of the cabinet (Fig. 2-1).
