NJ00675A-2 Dual Power Feed Unit Installation Procedure
Installation Procedure
Description
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.
DPFU Added Out-of-Service (New
Installation)
Description
This procedure involves the adding of a DPFU, on an out-of-service basis, to operate with
a SLC-2000 Remote Terminal Bay (RT) which utilizes dual power feeds.
Shelf Installation
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 front access, front mounting applications (RT) with
extended mounting, the brackets would be located in the forward position.
Step 2:
Mount the unit from the front of the bay (extended mounting), with the hard-
ware 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. For a RT the cable
is attached to the bay on same side as the equipment mounts. In this case the
cable must be passed through the oval, grommeted hole in order to reach the
front side. Remove the two 12-24 thread forming screws holding the bay
