6.3 Grid Connection
The connection procedure will vary depending on the grid configuration.
The following table provides an overview of the compatible grid configurations, of
which voltage limit, frequency limit and conductors have to be connected to the
inverter to comply with the grid configuration.
CAUTION!
The installer is responsible for providing overcurrent protection.
To reduce the risk of fire, connect only to a circuit provided with 63A
maximum branch-circuit overcurrent protection in accordance with
the National Electrical Code, ANSI/NFPA 70.
