Connecting Inverter to AC Grid
Danger to human life due to high voltage existing inside the inverter!
Make sure that all the DC and AC cables to the inverter are not live before
you start the electrical work.
Do not turn on the AC side circuit breaker until all inverter electrical
connections have completed.
Step 1 Disconnect AC circuit breaker and prevent it from reconnection
inadvertently.
Step 2 Loose the six screws on the lower connection cabinet.
Step 3 Strip off AC cables as shown below.
For flexible cables (stranded wires), use cold pressing terminal lugs
(plastic sleeves).
The cross-section of the AC cable conductor must be sized in order to prevent
accidentally disconnections of the inverter from the grid due to high impedance of
the cable that connects the inverter to the power supply point.
