● If the external AC switch provides the leakage protection function, the rated
residual operating current must be greater than or equal to 300 mA.
● If multiple inverters are connected to the master leakage protection device
through their external AC switches, the rated residual operating 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.
● Ensure that the cable jacket is inside the connector.
● Insert the exposed core wires completely into the holes.
● Connect the AC output cable securely. Otherwise, the device may fail to operate
properly or the AC connector may be damaged.
● Ensure that the cable is not twisted.
Strip the insulation layers of the AC output power cable by the recommended
length (17–19 mm) to ensure that the cable conductors are completely inside the
conductor insertion points and no insulation layer is pressed into the conductor
insertion points. Tighten the cable conductors to a torque of 2.8–3.2 N·m.
Otherwise, the device may fail to run properly or be damaged during operation.
