RISK OF SHOCK. Before performing any procedure, you must disconnect the power to the charging station at the service panel. Follow local code to de-energize the applicable circuit and lock out/tag out the disconnect before proceeding. Use a multimeter to test that power is off. Keep power off for the circuit until all cover panels are correctly reinstalled and the work is complete. FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN SERIOUS INJURY, LOSS OF LIFE, AND/OR PROPERTY DAMAGE.
Use low torque settings when working with power tools during installation or servicing. Over-torquing can damage the equipment.

Remove the Charging Cable

To remove the charging cable, complete the following steps:

  1. Turn off power to the station at the circuit breaker.

  2. Lift the faceplate off by pulling down on the two tabs located on the bottom of the faceplate, then pulling the faceplate away from the charging unit.

  3. Use a coin to unlock the wire cover.

    To avoid damage to the wire cover, do not use a screwdriver.

  4. Lift the wire cover off.

  5. Push up on the charging cable to relieve tension then slide the cable clip out. If it is difficult to remove, try sliding the coin under the cable clip and simultaneously sliding the clip out over the coin.

  6. Lift the three levers on the right side of the terminal block to remove the green, red, and black wires, and unplug the 4-pin connector.

    Do not lift or remove the three left-most levers and wires. Only the three right-most levers and wires, along with the 4-pin connector, are being lifted and replaced.

  7. Slide the charging cable out through the hole at the bottom of the station. You might need to squeeze the black wire harness that holds the three wires together, along with the 4-pin connector.

If you intend to revert from a NACSClosed North American Charging Standard cable back to a J1772 cable, store the original J1772 cable securely for future use.

Replace the Charging Cable

To replace the charging cable, complete the following steps:

  1. Unwrap the new charging cable.

  2. Remove the cable clip from the cable. Squeeze the wires and black wire harness and, along with the 4-pin connector, insert them into the opening on the lower right side of the station, pushing up until the cable collar is flush against the enclosure.

    Ensure that the guide pin on the cable collar goes into the corresponding hole on the bottom of the enclosure.

  3. Insert the green wire in the third from right terminal; the red wire in the second from right terminal; and the black wire in the right-most terminal of the output block; then insert the 4-pin plug into the connector to the right of the terminal block.

  4. Push the cables up until the silver conductors are no longer visible.

  5. Snap the white levers all the way down on each wire.

    The levers snap shut with great force. Keep fingers away from underneath the levers.
    6. Ensure each wire is fully inserted into the connector with no bare wire exposed before pressing it into place with the white lever.

  6. Push up on the charging cable to relieve tension then slide the cable clip in. This secures the cable and provides strain relief.

Attach the Wire Cover and Faceplate

To attach the wire cover and faceplate, complete the following steps:

  1. Replace the wire cover over the exposed wiring.

  1. Use a coin to lock the wire cover in place.

    To avoid damage to the wire cover, do not use a screwdriver.

  2. Snap the faceplate onto the charging station.
