5.4 Installing DC Input Power Cables
Precautions
● 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 inverter DC SWITCH is
OFF. Failing to do so may result in electric shocks.
● When the inverter is operating, it is not allowed to work on the DC input power
cables, such as connecting or disconnecting a PV string or a PV module in a PV
string. Otherwise, electric shocks may occur.
● If no PV string connects to a DC input terminal of the inverter, do not remove
the watertight cap from the DC input terminals. Otherwise, the protection level
of the inverter will be
aected.
