Installation - Junction Box Wiring
In order to power the EVCC evSmartPlug and monitor the voltages of the two receptacles/mobile chargers during charging sessions, several wires extending from the EVCC enclosure must be terminated to their applicable counterparts in the contactor junction box.
This section describes the steps necessary to first cut the EVCC whip wires to their proper length and connect the various terminals to their ends, then feed all of the wires (EVCC power, power meter, contactor coil, current transformer) through a 1 inch hole drilled out in the contactor junction box.
Follow These Steps
Follow the steps below to cut and terminate the EVCC whip wires to the proper length, then feed the wires through the contactor junction box top cutout. Beyond that, the wires can be fastened to the various contactor termination points.
For these steps, you will need the EVCC and attached wiring whip, contactor junction box, 2 x 50a contactors, and wire terminals. For tools, you will need a Phillips-head screwdriver, flat head screwdriver, and the wire stripper/crimper.

The EVCC ships with 4ft long whip wires so that the unit can be installed in many configurations such as a within 5 x 5 vinyl lamp post. When installing the EVCC with the indoor receptacle kit, these wires need to be trimmed to about 6 inches each from the bottom of the conduit whip and terminated with the proper connectors as shown in the image above.
Important Note: Notice that each wire is labeled at the top according to its function as shown to the right. Be sure not to strip away the labeled insulation of the wires. The labels are critical to understanding the termination point of each wire.

Using the wire stripper, strip about 5 inches of the outer insulation from each cable (Volt1, Volt2, Con1, Con2, CT1, CT2, Pwr), then strip about 1/4 of an inch of the insulation of each wire.

Using the crimp tool, crimp the provided terminals to the bare ends of each wire as follows:
* Red female connectors (4) -> CT 1 and 2 leads
* Red 6 stud Y terminal s(2) -> Pwr leads (leave ground bare)
* Red 6 stud Y terminals (4) -> Con 1 and 2 leads
* Yellow 8 stud ring terminals (4) -> Volt 1 and 2 leads (leave ground bare)
WARNING: Be sure these terminals are crimped securely to the wires so that a wire cannot break free of the terminal. Loose, bare wires can be dangerous in a high voltage enclosure.

On the EVCC conduit whip, remove the ring fastener screwed onto the conduit connector, then feed all of the EVCC wires through the top 1 inch cutout of the contactor junction box. From there, feed the ring fastener back through the whip wires and screw the fastener tight to the conduit connecter threads.

Pull the Con1, Con2, and the 2 Pwr leads under the DINrail and leaving the Pwr ground (green) alone.
NOTE: all "1" labeled cables should be positioned on the left side of the enclosure while all "2" labeled cables should be positioned on the right side of the enclosure.

With a flat-head screwdriver, tighten all ground wires (green wire: Volt 1, Volt2, Pwr) to the ground busbar of the junction box as shown. Be sure they are fastened tightly.
7
Using the Phillips-head screwdriver, tighten the contactor coil leads (Con 1, 2) to the left and right side coil termination points as shown. The black and white wires can be connected to either side. Perform this step to both the left and right side contactors.
NOTE: Be sure the contactor "L" and "R" are facing the top of the junction box.
