Warning Assembly of a Electric Vehicle charging station requires wiring Alternating Current (AC) components that will be exposed to voltages from 100 to 250v. If you do not have the experience and knowledge required to safely work with AC voltages please consult with an experienced electrician for assistance and inspection of your work.

Note Regularly inspect your charging station. Pay special attention to excess heat, components, handles, and wiring will be warm but they should not be HOT...

Always Disconnect your charging station from power before performing an inspection and/or maintenance

  2. Position the plate with the 4 holes for the OpenEVSE controller up top-left. Mount hex standoffs to the top side of the plate with 6 mm screws. Tip - use blue LOCTITE on each screw to ensure it remains tight.
    • Position the plate with the 4 holes for the OpenEVSE controller up top-left.

    • Mount hex standoffs to the top side of the plate with 6 mm screws.

    • Tip - use blue LOCTITE on each screw to ensure it remains tight.

    • Mount the Struthers-Dunn relay using 2 - 1/2" self threading screws.

    • Mount ground bar to the plate with 1 - 1/4" self threading screws.

  3. Attach the relay coil harness. Mount plate in enclosure with 6 coarse threaded 6mm screws. Install the cable glands.
    • Attach the relay coil harness.

    • Mount plate in enclosure with 6 coarse threaded 6mm screws.

    • Install the cable glands.

  4. Insert EV Cable through the Cable Gland on the right and tighten. Connect the ground wire to the ground block. Route the ground, pilot and coil wires low in the enclosure to avoid crossing any high voltage wires or components.

    • Connect the ground wire to the ground block.

    • Route the ground, pilot and coil wires low in the enclosure to avoid crossing any high voltage wires or components.

    • Thread ALL hot and neutral lines through the 4 wire GFCI coil with the orange self test loop.

    • Do not thread the ground wire or pilot wire through.

    • Thread EITHER hot OR neutral through the Current Measurement Coil.

    • Tip - zip tie smaller wires together near the top and bottom to keep them neat and out of the way.

  5. Screw the ring terminals on the EV cable power conductors to the relay along with the wiring harness. Connect the longer lead on the harness to the bottom position and the shorter the top position.
    • Screw the ring terminals on the EV cable power conductors to the relay along with the wiring harness.

    • Connect the longer lead on the harness to the bottom position and the shorter the top position.

    • Tip - run the top power wire in the middle of the enclosure with the smaller low voltage wires on the bottom. Ensure they is plenty of clearance.

    • Tip - run the bottom power wire high in the enclosure and angled away from the top power wire. Ensure there is plenty of clearance.

  6. Insert the input cable through the left gland. Connect the ground wire to the ground block. Screw the ring terminal on the EV cable power conductor to the top position of relay along with the red wire on the wiring harness.
    • Insert the input cable through the left gland.

    • Connect the ground wire to the ground block.

    • Screw the ring terminal on the EV cable power conductor to the top position of relay along with the red wire on the wiring harness.

    • Screw the ring terminal on the EV cable power conductor to the bottom position of relay along with the black wire on the wiring harness.

    • Tip - run the top power wire in low in the enclosure.

    • Tip - run the bottom power wire high in the enclosure and angled away from the top power wire. Ensure there is plenty of clearance.
