Power Source Installation
WARNING: All electrical components and installation practices must meet applicable national and local electrical
codes including installation by a qualied personnel. These codes may require an external junction box mounted on the
cabinet and a circuit breaker in the main wiring having a contact separation of at least 0.120” in the line and neutral poles.
The 120 VAC power source must be turned OFF prior to servicing. The power cable used for connection to the controller
must have an insulation rating of 221°F minimum.
Step 1 – For power source connection, install a 1/2” electrical
conduit from the 120 VAC power source to the MC-E
controller cabinet.
Step 2 – Install an electrical junction box at the transformer to
allow access for future servicing.
Step 3 – Conrm that power has been disconnected at the power
source using a volt meter or voltage detector.
Step 4 – Route 14-AWG insulated solid copper wires for Power
(Black), Neutral (White) and Equipment Ground (Green)
through the conduit and into the junction box.
Step 5 – Strip back 3/8” of insulation from each wire. Using wire
connectors, connect the wires with similar colors together
(Black with Black, White with White, etc.).
Step 6 – Tuck the wires inside the junction box and replace the
cover.
Step 7 – Apply power to the controller.
