6. Reconnect the P4 plug ground wire to the ground by the M10 bolt.

Take the following precaution when replacing printed circuit boards.

• Disconnect all drive power.
• Leave the replacement board in the anti-static bag until needed.
• Use an anti-static wrist strap, grounded in the low voltage control section.

There are no direct screw/terminal connections on any of the low voltage circuit
boards. All wire/terminal connections plug into the circuit boards. This means
that changing boards only requires the removal of the plugs, minimizing the
chance of mistakes when reconnecting all of the wiring.
