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.
