1.
Verify the inverter matches the grid-voltage.
2.
Release main circuit breaker and make
precautions to prevent reconnection.
3.
Open the front cover.
4.
Insert the cable through the AC gland to the
terminal blocks.
5.
The three mains wires (L1, L2, L3) and the Neutral
wire (N) are mandatory and must be connected
to the 4-pole terminal block with the respective
markings.
6.
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.
7.
All wires must be properly fastened with the
correct torque. See
4.6 Torque Specifications for
Installation
.
8.
Close the front cover, and remember to verify
that both front screws are applied with the
correct torque (6-8 Nm) to obtain PE connection.
9.
Close main circuit breaker.
CAUTION
For safety, check all wiring. Connecting a phase wire to the
neutral terminal may permanently damage the inverter. Do
not remove the short-circuit bridge at (1).
