Procedure
1. Open the cable gland, insert cables through the hole, and connect the cables to the L1, L2, L3, PE, and
N terminals.
ATTENTION: (Australia only) Do NOT connect the PE terminal of the BACK-UP port.
ATTENTION: If the grid cables are not connected correctly, an error “Master Grid Phase Error” will occur.
For details, refer to Chapter 7 “Troubleshooting”. If this error occurs, switch the position of L2 and L3
cables.
