5.3.2 Connecting the PV Input Power Cable
Prerequisites
The output wiring terminals of PV modules or connected optimizers may have hazardous
voltages. Touching the terminals may cause electric shock. Before connecting PV input
power cables, ensure that the DC SWITCH of the SUN2000 is OFF and that the DC input
terminals of the SUN2000 have no voltage.
When the SUN2000 is running, operations on the PV input power cable, such as
connecting or disconnecting a PV string or a PV module in a PV string, are not permitted,
due to the risk of electric shock.
If no PV string is connected to a DC input terminal of the SUN2000, do not remove the
waterproofing bolt from the DC input terminal. Otherwise, the IP rating of the SUN2000
will be affected.
