To remove the ACCB cover:

Place the loose screws and washers somewhere safe where they will
not be lost.

If the ACCB is already installed on the inverter, then slide the cover
away from the inverter before lifting, to remove the ACCB cover tabs
from the inverter slots.
To replace the ACCB cover:

If the ACCB is already installed on the inverter, then first insert the
three cover tabs into the appropriate slots on the AC side of the
inverter.

from the front and tighten into place.
3. Torque the #12 Phillips screws to 26-28 in-lbs.
