6.1 Precautions
When exposed to sunlight, the PV arrays supply DC voltage to the SUN2000. Before
connecting cables, ensure that the two DC switches on the SUN2000 are OFF. Otherwise, the
high voltage of the SUN2000 may result in electric shocks.

The equipment damage caused by incorrect cable connections is beyond the warranty
scope.

Only certified electrician can perform electrical terminations.

Wear proper PPE at all time when terminating cables.

To prevent poor cable connection due to overstress, it is recommended that the cables be
bent and reserved, and then connected to the appropriate ports.
The cable colors shown in the electrical connection diagrams provided in this chapter are for reference
only. Select cables in accordance with local cable specifications (green-and-yellow cables are only used
