Connect the low-current wires from the input side of the contactor to the AC_LINE inputs on the EFSE board. Connect the low-current wires from the output of the contactor to the AC_TEST inputs. Connect the contactor coil terminals to the DC relay outputs on the EVSE board. Connect the green ground wire from the EVSE board to the ground bar.

Connect the 2-pin connector from the current sense toroid to the 2-pin header on the EVSE board marked A_CT. Connect the 4-pin connector from the GFCI toroid to the header marked G_CT. The orange test wires go on the inside, next to the power supply block.

Connect the pilot wire (usually purple) from the EV cable to the terminal connector on the EVSE board. The EV cable may have an unused wire, which should be cut flush with the outer insulation. Verify all connections are correct and secure, then fasten with cable ties. The contactor armature must be completely free to move.

Slide the power cables through the cable glands and drop the assembled base plate into the polycarbonate box. Fasten the plate to the box in several positions using the supplied sheet-metal screws. Tighten the cable glands so that they grip the cables firmly.

Using a meter, verify all power connections. Ground on the input cable should connect to the ground bar and to the ground socket on the J1772 plug. L1 and L2 should connect through to the appropriate pins on the J1772 plug when the contactor is closed by hand, and should not be shorted together or to ground.
