Pre-Installation

Installing or Removing the Blockoff Plates

The unit is shipped with both upper and lower blockoff plates installed. If you are installing a single-inverter system, remove the upper blockoff plate only. If you are installing a dual-inverter system, then remove the lower blockoff plate also.

If a TX Autotransformer is to be installed in the lower position, remove the rectangular knockout in the lower blockoff plate. Do not remove the lower blockoff plate from that position.

Store the unused blockoff plates in a safe place, where they can be easily retrieved and reinstalled in the event that the inverter is removed for service.

WARNING: Shock Hazard

Be sure to disconnect all DC and AC power before removing the inverter and installing the blockoff plates.

Align the holes on the Blockoff Plate behind the holes provided from the inside of the ACCB-L chassis.

Secure with the eight 6x32 phillips screws provided.

Torque to 9-10 in-lb.
