5.2.4 Connecting the Inverter to Grid
High voltage inside the inverter!
Ensure all cables are voltage-free before electrical connection.
Do not connect the AC circuit breaker until all inverter electrical
connections are completed.
Step 1 Disconnect AC circuit breaker to prevent it from inadvertently
reconnecting.
Step 2 Loosen the six screws

on the lower connection
cabinet.
Step 3 Strip off AC cables as shown below.
For flexible cables (stranded wires), use crimping lugs.
The cross section of the AC cable conductor must be sized in order to prevent
accidental disconnections of the inverter from the grid due to high impedance of
the cable that connects the inverter to the power supply point.
