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.

8.1. Safety instructions for the AC connection

Consult section "Important Safety Instructions" and the following instructions before working on the
unit.
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.
Ingeteam accepts no liability for any damages caused by incorrect connection.
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.

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 size of the ground cable 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.

8.3. AC connection process

The wiring must be routed inside the unit via a conduit, which is inserted through a coupling in order
to maintain the unit's protection class.
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. Remove the threaded cap of the input hole and install the coupling using its insulating seal and nut.
2. Insert the plastic pipe that routes the cable through the coupling. Make sure the coupling is closed,
following the manufacturer's instructions.
3. Route the cable to the corresponding terminals using the guides provided in the unit.
