4.1.2 AC Power Installation

1. The AC power option includes a 120 VAC to 16 VAC step down

transformer. The transformer should be mounted inside a user-

supplied junction box according to local electrical codes.

Dangerous electrical accidents may be avoided by locating the

transformer remotely and burying a low voltage line to the station.

The low voltage will carry up to 500 feet on an 18 AWG power

cable.

2. Shut off 110 VAC power at the main breaker. Connect the primary

leads of the transformer to 110 VAC following instructions provided

with the transformer. Connect a two-conductor cable to the

secondary terminals of the transformer. Route the cable from the

transformer to the ET Enclosure according to local electrical codes.

3. Splice the incoming two-conductor cable to the power cable

provided with the station. Use the direct burial splice kit when

splices are in a valve box or buried.

4. Connect the power plug to the connector marked “Power” on the

back of the enclosure.
