Connecting Dc Power Cabinet Approved Ground; Connecting Ac Power To Dc Power Cabinet; Connecting Ground Wires For Dc Power Systems - Avaya G650 Installing

3
At the DC power cabinet, connect the wire to the ground discharge bar.
4
Route the wire through one of the holes in the side of the cabinets and terminate it on the ground
connection terminal in the DC battery cabinet.

Connecting DC power cabinet approved ground

To connect to the DC power cabinet approved ground:
1
At the DC power cabinet, connect a 1 AWG (#70) (44 mm
bar. See callout 2,
2
Route the ground wire out of the cabinet and terminate it on the approved ground. The approved
ground must be identified with a grounding tag (FORM 15657NR or equivalent). See the job aid
titled Approved Grounds (555-245-772) for more information.

Connecting AC power to DC power cabinet

1
Be sure the associated circuit breakers at the AC power panel are OFF.
2
Have an electrician connect AC power leads to the rectifiers using the instructions provided with
the rectifiers in the DC power cabinet. Each rectifier should have its own branch circuit.
Terminate leads on the AC INPUT terminal block of each rectifier.

Connecting ground wires for DC power systems

To connect ground wires for the DC power systems:
1
Connect a 6 AWG (#40) (16 mm
block.
2
Route the wire to the AC mains single-point ground block and connect.
3
Connect a 6 AWG (#40) (16 mm
terminal block. See callout 11,
page 81.
4
Route the wire(s) to the AC mains single-point ground block and connect.
5
Connect a 6 AWG (#40) (16 mm) wire to the DC battery cabinet. See callout 10,
Typical power and ground for a DC power cabinet,
6
Route the wires to the AC mains single-point ground block and connect. See callout 11,

NOTE:
The wire must be at least as large as the largest distribution wire in the MCC1 Media
Gateway (required by UL). In this example, 1 AWG is used.
Figure 34, Typical power and ground for a DC power cabinet,
CAUTION:
Power is present in the cabinet even if the AC power cable is unplugged. Turn off the main
circuit breaker on the front of the cabinet when procedures require ALL power to be
removed from the cabinet.
CAUTION:
Do not connect any ground wires between cabinets. All ground wires must be terminated
at the single-point ground block (not daisy-chained) at the main AC supply (AC mains).
