STEP 6 - CONNECT THE WIRING

Refer to the numbers on the previous wiring table and image. The plastic cover over the board has
raised printing on it that names each terminal.
1. Loosen the chassis ground screw terminal (1) with a flathead screwdriver.
2. Insert the ground/earth wire beneath the lug screw from the left side. Torque according to the
wire size:
2
• 2.5-5 mm (14-12 AWG): 4.0 Nm (35 lbf-in)
2
• 6-8 mm (10-8 AWG): 4.5 Nm (40 lbf-in)
3. Pull both high voltage locking tabs on the spring terminal (2) away from the board to open
them.
Note: New tabs can be difficult to close. Close and open each tab once without wires before
installation.
4. Route the positive (+) and negative (-) DC power wires behind the red and black internal DC
wires, and fully insert them into the spring terminal tabs. The left slot is Positive and the right
slot is Negative.
5. Close the locking tabs by pushing them up, so that the tab is flush with the connector. Close
tabs one at a time. Lightly tug on each of the HV wires to ensure it is secure. If any wire must
be removed, pull the locking tab open, then pull out the wire.
