5.4.2 Assembling AC Cables to Connector

The inverter is equipped with water-proof connector for AC connection, which
matches the AC terminal at the bottom of the inverter.
Danger to human life due to high voltage existing inside the inverter!
 Make sure that all the AC cables to the inverter are not live before the
electrical work.
 Do not turn on the AC circuit breaker until all electrical connections are
completed.
Prior to connecting to the utility grid, verify whether the grid voltage and frequency
are within the range of inverter output parameters, referred to "12 Appendix".
Consult local grid company for solution, if otherwise.
All AC cables should be equipped with correctly colored cables for
distinguishing. Please refer to related standards about wiring color.
Connecting Inverter to AC Grid
Observe the terminal layout of AC connector. If a phase wire is connected to
the "PE" terminal, the inverter will not function properly.
