9.1  ESC 864 Controller Replacement

The ESC-864 is typically replaced at the module level. Individual board level replacement is not recommended
or discussed in this section.

To replace the module, unscrew the two screws to the immediate right of the ESC-864 front plate. Remove all
connectors from the controller. Mark the connectors to ensure proper reinstalling. Lift the controller housing
directly upward, off of the L-shaped bracket. Reverse the procedure to install a new controller.

9.2  System Driver Board Replacement

Label all wires before removing them from the System Driver Board. Disconnect all wires and connectors at the
Driver Board. Disconnect the connector (with the red and black wires only) at the Power Amplifier(s). Remove
mounting hardware. Replace the board by reversing the procedure.

9.3  Power Amplifier Replacement

Remove the connectors from the Power Amplifiers. Remove the one screw on the ESC-864 front panel,
immediately above the Power Amplifier LEDs. Lift the Power Amplifier upward off of the L-shaped bracket.
Reverse the procedure to install a Power Amplifier.

A Power Amplifier is heavy. Be sure to have a firm grip on it before removing the mounting hardware.

9.4  Battery Charger Replacement

Make sure that the AC power cord is unplugged. Disconnect the cables. Remove four nuts from the back wall of
the charger. Reverse the procedure to install the Charger.

CAUTION

The IPS cabinet is a high-voltage unit. Wait five minutes after turning off AC power and disconnecting the
interconnect battery cable before removing any module. DO NOT allow the battery cable to touch the
aluminum cabinet.
