The cable colors shown in figures are for reference only. Select an appropriate cable according to the
local standards.
Before connecting DC input power cables, 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).
