Huawei SUN2000 MB0 Series User Manual

WARNING
● Do not connect loads between an inverter and an AC switch that directly
connects to the inverter. Otherwise, the switch may trip by mistake.
● If an AC switch is used with specications beyond local standards, regulations,
or the Company's recommendations, the switch may fail to turn o in a timely
manner in case of exceptions, causing serious faults.
CA UTION
Each inverter must be equipped with an AC output switch. Multiple inverters
cannot connect to the same AC switch.
The inverter is installed with an integrated monitoring unit for the residual
current. When the inverter detects that the residual current exceeds the permitted
value, it disconnects from the power grid quickly.
NO TICE
● If the external AC switch has residual current protection, its rated leakage
tripping current must be greater than or equal to 300 mA.
● If multiple inverters are connected to the master leakage protection device
through their AC switches, the rated leakage tripping current of the device
must be greater than or equal to the number of inverters x 300 mA.
● The AC switch cannot be a knife switch.
Procedure
Step 1 Connect the AC output power cable to the AC connector.
