If the network operator stipulates a residual-current protective device, you must use a
residual-current protective device that triggers in the event of a residual-current of 100 mA or more.
Connection of a second protective conductor
In some installation countries, a second protective conductor is required to prevent a touch current in
the event of a malfunction in the original protective conductor.
For installation countries falling within the scope of validity of the IEC standard 62109, you must install
the protective conductor on the AC terminal with a conductor cross-section of at least 10 mm²Cu.
Or install a second protective conductor on the earth terminal with the same cross-section as the original
protective conductor on the AC terminal
Load disconnection unit
You must install a separate three-phase miniature circuit-breaker or other load disconnection unit for each inverter
in order to ensure that the inverter can be safely disconnected under load.

Measure the public grid voltage and frequency (Voltage: 400Vac; Frequency: 50Hz/60Hz; in 3-Phase);

Open the breaker between the PV inverter and utility;
