5.5 Installing the DC Input Power Cable
5.5.1 Cable Connection Description
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
SUN2000 is OFF. Failing to do so may result in electric shocks.
● When the SUN2000 is running, 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. Failing to do so may cause electric shocks.
● If no PV string connects to a DC input terminal of the SUN2000, do not remove
the watertight cap from the DC input terminals. Otherwise, the IP rating of the
SUN2000 will be
aected.
