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 two DC switches on the SUN2000 are set to OFF.
Failure to do so may result in electric shocks.
When the SUN2000 operates in grid-tied mode, do not to 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 lower than or equal to 1500 V
DC.
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 SUN2000.
