Step 4
. Remove the bottom cover of the inverter where AC terminals are by unscrewing the 3 screws
that hold it, 2 near the fans and the other in the opposite side (as it is illustrated in the below figure). Due
to the air seal located between the inferior and superior cover, placed to avoid the entrance of liquids in
the system, the extraction of the inferior cover can be difficult, for it, also clears the screws of the
indicated superior cover n the following image and this one will leave with extreme facility.

Step 5
. Insert AC cables through the gland located on the left bottom corner, through rubber bushing,
and AC-output cover. Then, insert Ground through the same enclosure.
Step 6.
The choice of cable together with the way it is routed, the ambient temperatures the inverter
operates at, and other underlying conditions determines the maximum AC fuse protection used for the
inverter.
