9.1. Safety instructions for the AC connection

DANGER
Make sure there is no voltage present in the unit and that the DC connection has not been made before starting
the AC connection.
Do not switch on the powerto the unit until you have successfully made the rest of the connections.
Use the Personal Protective Equipment specified in the section
Respect the polarity of the AC wiring.
CAUTION
Ingeteam accepts no liability for any damages caused by an incorrect connection.
The communications for this inverter are also powered from the AC section.

9.2. Wiring requirements for the AC connection

To guarantee the safety of persons, for the unit to function correctly and comply with the applicable standards, the
unit must be connected to the ground of the installation.
If the inverter and the grid connection point are far enough apart to require the use of cables with a larger gage, an
external distribution box should be used close to the inverter to make this connection.
The AC connection must be made using single-pole wires. A total of five cables are used: three phases, neutral
(optional) and ground. The conductor material may be copper or aluminum.
Wiring
Single-pole 5 single-pole cables (L1, L2, L3, PE, N
Optional, the inverter is able to operate without the neutral connection.

CAUTION
If using aluminum cables, the installer must provide the necessary means to prevent galvanic coupling (bipolar
terminals, bimetallic interfaces, etc.).
The dimensioning of the ground wiring will be the responsibility of the installer and must meet applicable
regulatory requirements in the installation.
