2.9 Modular Transformer Assembly (MTA)

2. INSTALLATION

The APC and APL’s modular transformer assembly is designed for quick installation

and removal. A captive screw in the baseplate secures the MTA into the enclosure.

BEFORE PROCEEDING WITH THE INSTALLATION OF THE MTA, THE

ENCLOSURE MUST BE MOUNTED, AND UTILITY / CABLE LINES SHOULD BE

WIRED AS PREVIOUSLY DESCRIBED IN THE MANUAL.

2.9.1 Pole-mount (PM) and Wall-mount (WM) Photo 2.9.1

Procedure:

1. Place the Modular Transformer Assembly onto the baseplate. Make sure

that the slot in the MTA fits onto the tab on the top of the baseplate unit.

2. Secure the MTA using the captive screw on the lower portion of the

baseplate. Tighten the screw.

3. There are three (3) white connectors located on the left-hand side of the

MTA, (two 2-pin and one 3-pin). Each connector is attached to a black and

white wire harness. Two (2) of the 2-pin connectors are free and the one (1)

3-pin connector will contain a shorting plug for the TDR/M option. Do not

remove this shorting plug, refer to the options section of this manual.

Connect one of the free 2-pin connectors to the output connector attached

to the baseplate.

NOTE: The APL contains only one (1) 2-pin connector. This is the output connector

and must be mated to the enclosure’s VSF output connector.

2.9.2 Pedestal-mount (PED) Photo 2.9.2

The pedestal-mount enclosure utilizes the same modular transformer assembly as

the pole-mount units. The PED model uses the Universal Bracket 1 (UB1) instead

of the baseplate which is similar in appearance with the exception of an additional

mounting bracket

Procedure:

1. Position the slot on the extended portion of the universal bracket over the

stud located on the lower inside rear portion of the pedestal unit. The top of

the UB1 is secured using a wing-nut that is placed on the provided carriage

bolt installed on the PED near the top of the enclosure.

2. Place the MTA on the Universal Bracket by carefully sliding it

downward.

The slot in the top of the MTA fits over the tab on the UB1.

3. Secure the MTA using the captive screw on the lower portion of the

universal bracket assembly, and tighten screw.

4. Refer to step 3., paragraph 2.9.1, above.

NOTE: The APL contains only one (1) 2-pin connector. This is the output connector

and must be mated to the UB1’s VSF output connector.
