The shelf-mount version of the APC (APL) consists of the standard MTA (Modular

Transformer Assembly) which rests on a mounting plate (SM). The mounting plate

and MTA can then be installed into an enclosure such as the PED- M, PWE or

UPE. The shelf-mount option also includes an input AC power extension cable

(APC model only) and an APC - SPI adaptor.

NOTE: BEFORE INSTALLING THE APC, ENSURE THAT ALL OPTIONS HAVE

BEEN INSTALLED AND PROPERLY CONNECTED. REFER TO SECTION 2.11

OPTIONS, FOR INSTALLATION INSTRUCTIONS.

Procedure: Photos 2.6.a, .b, .c

1. Place the modular transformer assembly (MTA) onto the shelf-mount (SM)

by fitting the slot on the top of the MTA over the tab on the SM bracket.

2. Locate the captive screw on the opposite side of the shelf-mount adaptor

(next to the terminal block). Fit this captive screw into the threaded portion

of the MTA and tighten.

3. Place the assembled shelf-mount bracket and modular transformer

assembly into the shelf of the enclosure (PED-M, PWE or UPE). Place one

of the key-slot holes over the threaded screw hole in the enclosure’s shelf.

Install a 8-32 x 1/2” long screw and tighten. NOTE: Only one of the screw

holes is used to mount the SM onto the enclosures shelf. To install

additional APC-SM’s into the enclosure, you will need to drill and tap

another mounting hole.

4. Connect the AC input power extension cable to the AC power cable on the

unit. Connect the plug of the extension cable into the enclosures AC

receptacle.

NOTE: The APL model is connected to the utility power via the terminal block on the

MTA

5. Output connection to the plant is accomplished via the terminal block or by

using SPI the APC - SPI adaptor cable.

6. The APC (APL) is now ready for the utility connection (see section 3.1

START-UP AND TEST).
