5 Electrical Connections
This topic describes the SUN2000 electrical connections. Read this part carefully before
protection ground (PGND) cables, DC input power cables, AC output power cables, and
communications cables for the SUN2000.
Context
Before performing any electrical connection, ensure that the DC SWITCH is OFF. Otherwise,
the high voltage can result in fatal injury.

The cable colors shown in electrical connection schematic drawings are only for reference.
Select cables according to local cable specifications (Yellow-green wires are only used for
grounding).

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.
