TRANSFORMER INSTALLATION

The Model TE5D transformer powers the DMC3-4 Master

Station. The Model TE2D transformer powers the optional

DMCMP3 CD/MP3 Player. Both transformers are supplied

in a small metal enclosures that mount in the bottom of the

wall housing.

1. Route the existing 120 VAC power cable (including ground) from a

dedicated 15-amp circuit breaker to the wall housing location. The

DMC3-4 requires a dedicated power source to assure there’s no

interference from other equipment. The ground is required for good

radio reception.

2. Slide the transformer enclosure(s) down into the rectangular

transformer mounting knockout(s) on the bottom of the wall housing

(see Figure 4).

3. If installing the second transformer for the CD/MP3 Player option, cut a

1-1/2 foot length of power cable to loop between the two transformers.

Insert an end of the cable into each of the transformer enclosures

through the bottom knockout holes. Use wire nuts to connect the cable

to the TE2D transformer BLACK (HOT) and WHITE (NEUTRAL) input

wires. Connect the GREEN (GROUND) wire to the cable’s ground

conductor (see Figure 5).

4. Route the incoming power cable into the TE5D transformer enclosure

through the bottom knockout hole. Use wire nuts to connect the

incoming power cable to the TE5D transformer BLACK (HOT) and

WHITE (NEUTRAL) input wires (and to the cable going to the TE2D

transformer if installed). Connect the GREEN (GROUND) wire to the

cable(s) ground conductor (see Figure 5).

5. Be sure all power cables entering the transformer enclosure(s) are

secured with cable strain reliefs.

6. Tuck the cables into the transformer enclosure(s) followed by the

transformer on its mounting plate. Secure the transformer(s) and

enclosure(s) to the wall housing with the screws supplied (see

Figure 6).

WARNING

ALL AC ELECTRICAL CONNECTIONS TO THE POWER SOURCE

AND THE TRANSFORMER(S) MUST BE MADE BY A LICENSED

ELECTRICIAN AND MUST OBSERVE ALL NATIONAL AND LOCAL

ELECTRICAL CODES.
