SC 4812ET/SC 614 BTS DC Power Sharing
The SC 614 MUST NOT be connected to an AC source in
this configuration. As shown in Figure D-1, AC should
ONLY be connected to the SC 4812ET Power Cabinet. To
ensure that accidental AC connection cannot occur to the
SC 614, the four AC Power cables that connect from the
SC 614 AC Load Center to each of the Power Supply units
should be removed. Failure to do this could result in
damage to the SC 614 Power Supplies and misoperation of
the entire system.
Due to the reduction in load capacity of the power cabinet, the
battery/rectifer configuration and number of sector–carriers that can be
supported in the SC 4812ET RF Cabinet are changed compared to the
standard SC 4812ET documentation.

The objective of this procedure is to connect the DC power cable from
the Power Cabinet to the SC 614 BTS.
Battery Power must be removed from the system until all
connections are made to the BTS.
