8. AC connection.

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

8.1. Safety instructions for the AC connection

DANGER
Make sure there is no voltage present on the unit before starting the 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 the section "Personal Protective Equipment (PPE)".
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.
CAUTION
Ingeteam accepts no liability for any damages caused by 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 gage, an
external distribution box should be used close to the inverter to make this connection.
The AC connection must be made by a multipole conduit with five copper wires (three phases, neutral and ground).
Single-pole cables may not be used because when they go through the packing gland it is not possible to ensure
the protection rating is maintained.
The dimensioning of the ground wiring will be the responsibility of the installer and must meet applicable
regulatory requirements in the installation, with a minimum gage equal to that of phase and neutral. In any case, it
should not be smaller than 6 mm
The entrance allows for a cable section of up to 50 mm

8.3. AC connection process

DANGER
Respect the installation of L, N and ground as described in this section for correct operation and for the safety
of the installation. If the lines L and N are reversed the inverter will not work.
Ingeteam accepts no liability for any consequences of incorrect connection.
1. If the cable used has a diameter of between 16 and 23 mm, use the reducer that comes with the packing
gland. If the cable has a diameter of between 23 and 35 mm, discard this reducer.
2. Pass the cable through the packing gland and guide it to the corresponding terminal.
