5.5 Connecting 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 two DC switches on the SUN2000 are OFF.
Failing to do so may result in electric shocks.
When the SUN2000 is grid-tied, it is not allowed to work on DC circuit, such as
connecting or disconnecting a PV string or a PV module in a PV string. Failing to do so
may cause electric shocks or arcing (which may further cause fire).
Ensure that the following conditions are met. Otherwise, the SUN2000 will be damaged, or
even become a fire hazard.
The open-circuit voltage of each PV string is always lower than or equal to 1100 V DC.
The positive and negative terminals of a PV string are connected to corresponding positive
and negative DC input terminals of the SUN2000.
