This chapter explains the requirements and process for wiring the DC wiring to the unit.
Read carefully before starting the connection process.

9.1. Safety instructions for the DC 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.
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.

9.2. Wiring requirements for the DC connection

9.3. DC connection process

1. Relative to the installation characteristics, use one or two couplings. For each input, 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.
