Power supply connection
8. Power supply connection
This chapter explains the requirements and process for connecting the power supply cabling 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 connecting the power supply
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 section "Personal Protective Equipment (PPE)".
During the connection, 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 power supply wiring.
CAUTION
Ingeteam accepts no liability for any damages caused by an incorrect connection.
8.2. Wiring requirements for connecting the power supply
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 charger 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 charger to make this connection.
The power supply connection must be made using single-pole cables. A total of 3 or 5 cables will be used
depending on if a single phase supply is connected (phase, neutral and ground) or three phase (three phases,
neutral 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 rated current of the switch or terminal block for the connection is 80 A, depending on the model.
INFO
A three phase unit can work as a single phase unit connected to only one phase, neutral and ground, provided
the phase is connected to the unit's R phase.
The dimensioning of the ground wiring will be the responsibility of the installer and must meet applicable
regulatory requirements in the installation.
8.3. Power supply connection process
1.
Insert the wiring through the cable inlets provided in the lower part of the charger.
2.
Establish the connection respecting the polarities according to the type of unit.
