Precautions

D ANGER

Before connecting cables, ensure that the DC switch on the SUN2000 and all the

switches connecting to the SUN2000 are set to OFF position. Otherwise, the high

voltage of the SUN2000 may result in electric shocks.

WARNING

● The device damage caused by incorrect cable connections is not covered under

any warranty.

● Only certified electricians are allowed to connect cables.
● Operation personnel must wear proper PPE when connecting cables.

NO TE

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 for PE).
