Before connecting the DC input power cable, ensure that the DC voltage is within the safe
range (lower than 60 V DC) and that the three DC switches on the inverter are set to OFF.
Failure to do so may result in electric shocks.
When the inverter operates in grid-tied mode, do not perform maintenance or operations
on the DC circuit, such as connecting or disconnecting a PV string or a PV module in the
PV string. Failure to do so may cause electric shocks or arcing, which may also cause fire.
The open-circuit voltage of each PV string must always be 1500 V DC or lower.
The polarities of electric connections are correct on the DC input side. The positive and
negative terminals of a PV module connect to corresponding positive and negative DC
input terminals of the inverter.
