The following procedures are divided into three distinct areas depending on whether you
are (1) adding a DPFU at the time of the initial SLC-2000 installation, (2) changing out a
DPFU that has failed or (3) adding a DPFU to an in-service system. Select the procedure
that meets your situation.
This procedure involves the adding of a DPFU, on an out-of-service basis, to operate with
a SLC-2000 Remote Terminal Bay (RT) or a SLC-2000 Central Office Terminal Bay (COT)
both of which utilize dual power feeds.
Step 1: This unit is provided with removable mounting brackets that can be positioned
in one of two positions on each side of the shelf depending on the type of
framework used. For rear access, rear mounting applications (COT) the brack-
ets would be in the rear position for a flush mount arrangement. Adjust brack-
ets as required.
Step 2: For a COT mount the DPFU from the rear of the bay (flush mounting), with the
hardware provided (.12-24 X 1/4"), at the top of the bay using mounting holes
#77 and #78 respectively.
Step 3: Locate the NE00675-31, G3 green/yellow ground strap shipped with the
DPFU. Connect one double lug securely to the rear of the DPFU with the lug to
the left, as viewed from the rear. The other lug will be attached to the top of the
frame using the same holes used for the bay ground cable. Remove the two
12-24 thread forming screws holding the bay ground cable in order to refasten
the same and the DPFU ground lug. Lugs should be positioned in an overlap-
ping manner with wires going in opposite directions.
