Specifications .
The illustration shows the stripping of insula-
tion of all 5 wires of the AC cable. The length
of the PE wire must be longer than the mains
and neutral wires.
1. Verify L-N and L-L grid voltages.
2. Release main circuit breaker and
make precautions to prevent recon-
nection.
3. Open the front cover.
4. Unscrew the cap on the AC gland and
slide it over the cable.
5. Insert the cable through the AC
gland to the terminal blocks.
6. Loosen the screws in the terminal
block to allow the wires to be inser-
ted. Fasten the screws to secure the
wires.
7. The three mains wires (L1, L2, L3)
and the Neutral wire (N) are manda-
tory and must be connected to the 4-
pole terminal block with the respec-
tive markings.
8. The Protective Earth wire (PE) is
mandatory and must be connected
directly to the chassis PE terminal.
Insert the wire and fasten the screw
to secure the wire.
9. All wires must be properly fastened
with the correct torque to ensure
strain relief.
10. Fasten the AC gland to the inverter.
11. Close the front cover, and remember
to verify that both front screws are
applied with the correct torque to
obtain PE connection.
12. Remove precautions.
