Before connecting the inverter to the grid, ensure the grid voltage and frequency comply with
requirements, for which, refer to
"Technical Date"
. Otherwise, contact the electric power
company for help.
AC Circuit Breaker
An independent three or four-pole circuit breaker must be installed on the output side of the
inverter to ensure safe disconnection from the grid.

AC circuit breakers should be installed on the output side of the inverter and the
grid side to ensure safe disconnection from the grid.
•
Determine whether an AC circuit breaker with greater overcurrent capacity is re-
quired based on actual conditions.
•
Do not connect any local load between the inverter and the AC circuit breaker.
•
Multiple inverters cannot share one AC circuit breaker.
Residual Current Monitoring Device
With an integrated universal current-sensitive residual current monitoring unit included, the
inverter will disconnect immediately from the mains power once a fault current with a value
exceeding the limit is detected.
However if an external residual current device (RCD) is mandatory, the switch must be trig-
gered at a residual current of 300 mA (recommended), or it can be set to other values ac-
cording to local regulations. For example in Australia, the inverter can use an additional 30
mA(type A)RCD in installations.
6.5.2 Assembling the AC Connector
The AC terminal block is on the bottom side of the inverter. AC connection is the three-
phase-four-wire grid + PE connection (L1, L2, L3, N, and PE).
step 1 Unscrew the swivel nut of the AC connector.
