5.4 Connecting DC Input Power Cables
Connect the SUN2000 to PV strings over DC input power cables.
Prerequisites
PV modules generate electric energy when exposed to sunlight and can create an electrical
shock hazard. Therefore, when connecting DC input power cables, shield the PV modules
with opaque cloth.
Before connecting DC input power cables, ensure that the voltage on the DC side is within
the safe range (lower than 60 V DC) and that the DC SWITCH on the SUN2000 is OFF.
Otherwise, high voltage may result in electric shock.
When the SUN2000 is grid-tied, it is not allowed to maintain DC input power cables, such
as connect or disconnect a string or a module in a string. Otherwise, it may result in
electric shock.
