3. To connect to transformers with the low-voltage winding in delta or to transformers without the neutral
accessible, it is necessary to change the position of a wire in the -CCU. Connect the cable going to -J10.1
(labeled as N on the card) from the -CCU in J10.2.

16.4.1. Wiring and terminal requirements for the AC connection
If using wiring for the AC connection, it must meet the following requirements.
Wiring
• The correct dimensioning of the AC wiring is the installer’s responsibility, depending on the plant
specifications and inverter characteristics.
• The wire gauge must be based on each unit’s continuous currents. Incorrect dimensioning can lead to
overheating and fires.
• Only copper or aluminum cable must be used.
• The cables for connection to the unit grid must withstand at least the phase voltage and 1000 V between
a phase and ground.
• If the inverter and the grid connection point are far enough apart to require the use of longer cables, an
external distribution box must be used close to the investor to make this connection.
Terminals
• For AC connections, compression terminals must be used. The terminals used can be with 1 or 2 holes.
