Installing an NT6D82 Power System

QBL15, QCA13
DC-powered systems generally require one AC-input receptacle per rectifier
within 1.8 m (6 ft) of each rectifier. The input receptacles required are
determined by the number and type of rectifiers used.
Note: Depending on the distance between the input receptacle and the
pedestal, a junction box may be required if the column is equipped with
a vintage AA or DA NT7D10 PDU. A junction box may be used with the
NT7D67CB PDU, but it is not required.
For information on customer-supplied power equipment, refer to Appendix
D: "Customer supplied power equipment" on page 471.
The NT6D82 Power System can be used with all system options, but it is
optimized for options 71 and 81 (and larger option 61 and 61C
configurations).
The NT6D82 Power System is an enclosed, front-access power distribution
and control panel that supports from one to three 100-amp rectifiers per rack.
One to three racks can be paralleled in a single configuration. The maximum
capacity of three fully equipped racks is 900 amps.
The rectifiers in an NT6D82 operate on single-phase, 60 Hz, AC service and
can be strapped for either 120, 208, or 240 V nominal input. The NT6D82
Power System requires one 50-amp power feed per rectifier.
To install an NT6D82 Power System, follow the instructions provided with
the NT6D82 equipment.
