5.4 Connecting an AC Output Power Cable
Precautions
An AC switch should be installed on the AC side of the inverter. To ensure that the
inverter can safely disconnect itself from the power grid when an exception occurs,
select a proper overcurrent protection device in compliance with local power
distribution regulations.
● 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 specications 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.
Each inverter shall be equipped with an AC output switch. Multiple inverters shall
not connect to the same AC switch.
The inverter is installed with an integrated monitoring unit for residual current.
When the inverter detects that residual current exceeds the permitted value, it
disconnects from the power grid quickly.
