5.5 Installing the DC Input Power Cable

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 affected.
