6 Electrical Connection

The electrical connection can be carried out when the mechanical installation
of inverter is completed. The following operation specification must be followed
when making electrical connection.

Warning

！

●

All the electrical connection must meet local electrical connection
standard.

●

Only qualified electrical personnel can perform the wiring installation
work.

●

Incorrect wiring operation may cause operating casualties or equipment
damage permanently.

●

Ensure that there is no electricity in DC side before the electrical
connection.

●

Grounding correctly, using proper conductor and taking necessary
Short-circuit protection to ensure the safe operation of inverter.

●

Don’t try to close any breaker before all the electrical connection is
finished.
