5.4 Connecting DC Input Power Cables
Precautions
D ANGER
● Before connecting the DC input power cables, ensure that the DC voltage is
within the safe range (lower than 60 V DC) and that the DC SWITCH on the
inverter is OFF. Otherwise, the high voltage may result in electric shocks.
● When the inverter is operating, do not perform maintenance or operations on
the DC input power cables, such as connecting or disconnecting a PV string or a
PV module in the PV string. Otherwise, electric shocks may occur.
● If no PV string connects to a DC input terminal of the inverter, do not remove
the waterproof cap from the DC input terminal. Otherwise, the protection level
of the inverter will decrease.
