An independent two-pole circuit breaker must be installed on the output side of the in-
verter to ensure safe disconnection from the grid. The recommended specifications are
as follows.

•
Determine whether an AC circuit breaker with greater overcurrent capacity is
required based on actual conditions.
•
Multiple inverters cannot share one circuit breaker.
•
Never connect a load between the inverter and the circuit breaker.

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
triggered at a residual current of 300 mA (recommended), or it can be set to other val-
ues according to local regulations. For example in Australia, the inverter can use an ad-
ditional 30 mA (type A) RCD in installations.
6.6.2 Connecting the AC Cable
step 1
Disconnect the AC circuit breaker and secure it against reconnection.
step 2
Unscrew the swivel nut and take out the sealing ring.
