This chapter explains the requirements and process for connecting the AC wiring to the unit.
Read carefully before starting the connection process.
INFO
Consult section "Important safety instructions"

8.1. 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 power to the unit until you have successfully made the rest of the connections and the unit
is closed.
Use the Personal Protective Equipment specified in section
While connecting the inverter, make sure of the proper installation of the cables on the unit´s terminals so that
parts of accessible wires do not remain live.
Respect the polarity of the AC wiring.
CAUTION
Ingeteam accepts no liability for any damages caused by an incorrect connection.

8.2. 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 gauge,
an external distribution box should be used close to the inverter to make this connection.
The AC connection must be made using single-pole cables. A total of four cables are used: three phases and
ground. The conductor material may be copper or aluminum.
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.
The AC input admits a cable section of between 70 mm
diameter is 12 to 28 mm. The cables must finish in an M12 spade terminal. The maximum width of the spade
must not exceed 40 mm.

8.3. AC connection process

INFO
The unit is equipped with different cable entry systems to facilitate the installation with any cable section
chosen by the installer.
1. Access the lower compartment of the inverter.
2. Remove the polycarbonate guard.
3. The elements to use vary depending on the cable diameter. The possible cases are explained below.
