DANGER Danger to life due to fire! You must protect each SMILE-B3-PLUS with an individual AC circuit breaker in or-der to ensure that the system can be disconnected safely.

MOUNTING 29

Do not connect loads between the SMILE-B3-PLUS and the grid breaker. For load switching, please use dedicated circuit breakers with load switch function. The selection of the AC circuit breaker rating depends on the wiring design (wire cross section area), cable type, wiring method, ambient temperature, inverter current rating, etc. Derating of the AC circuit breaker rating may be necessary due to self-heating or if exposed to heat.
The maximum AC current of SMILE-B3-PLUS can be found in the following table. We recommend the following AC circuit breaker for AC connection.

NOTICE
For Australia and New Zealand installation site, the neutral cable of grid side and backup side must be connected together, otherwise backup output function will not work.
Residual Current Protection The inverter is equipped with an all-pole sensitive residual current monitoring unit (RCMU) with an integrated differential current sensor which fulfills the requirement of DIN VDE0100-712(IEC60364-7-712:2002). Therefore, an external residual current device (RCD) is not required. If an external RCD needs to be installed because of local regulations, a RCD type A or type B can be installed as an additional safety measure. The all-pole sensitive residual current monitoring unit (RCMU) detects alternating and direct differential currents. The integrated differential current sensor detects the current difference between the neutral conductor and the line conductor. If the current difference increases suddenly, the inverter will disconnect from the grid. The function of the all- pole sensitive residual current monitoring unit (RCMU) has been tested according to IEC62109-2.
