AC Side Circuit Breaker
An independent two-pole circuit breaker for the inverter must be installed at the
output side to ensure that the inverter can be securely disconnected under load.

y
It is not allowed for several inverters to use the same circuit breaker.
y
It is not allowed to connect loads between the inverter and the circuit
breaker.
Residual Current Device
With an integrated universal current-sensitive residual current monitoring unit
inside, the inverter is able to distinguish the fault current from normal capacitive
leakage current. The inverter will disconnect immediately from the mains when a
fault current out of the limit value has been detected.
However if an external RCD or residual current breaker is mandatory, the switch
must be triggered at a failure current of 300mA or higher.
5.4.2 Assembling AC Cables to Connector
Inverter is equipped with water-proof direct plug-in connectors for AC connection,
which match AC terminals at the bottom of the inverter.
“L”, “N” and “PE” should be equipped with correctly colored cables for
distinguishing. Please refer to related standards for specific wiring color.
