Connecting auxiliary services

11. Connecting auxiliary services
INFO
If the unit incorporates the Auxiliary Services kit by default, the connections indicated in this section are not
necessary.
To find the different components listed below, consult Section "2.6. Location of components".
Refer to Section "Important safety instructions" and the safety paragraph in this section before operating the
equipment.
These units have alternating current to power certain of the unit´s elements, like the fans, power sources or
motorized DC switch.
This auxiliary voltage must be 220 V 50/60 Hz between phase and neutral.
This chapter explains the requirements and process for wiring the auxiliary wiring to the unit.
Read carefully before starting the connection process.

11.1. Safety instructions for connecting auxiliary services

DANGER
Before starting the connection process, press the emergency stop button and keep it interlocked until all the
connections required for the unit to operate correctly have been made.
Make sure there is no voltage present on the unit before carrying out any connections. Once the inverter is
switched off, wait at least 10 minutes until internal capacitances are fully discharged.
After connecting the ancillary services, do not switch on the power until you have made all other connections and
the unit has been closed.
Failing to apply the correct tightening torques to the connection terminals causes a risk of overheating and fire.
Use the Personal Protective Equipment specified in section "Personal Protective Equipment".
CAUTION
In order to keep the nuts and bolts of the unit in good condition it is important to make sure there is no dirt or
shavings in the threads when screwing them in and apply a suitable lubricant.
Ingeteam accepts no liability for any damages caused by an incorrect connection.

11.2. Connection area

The terminal block for making the auxiliary AC connections is -XAUX located in DCAC connections module.
The thermomagnetic breaker -Q2 protects the auxiliary AC connection.
During connection, make sure that the thermomagnetic circuit breaker -Q2 is in the OFF position. To check correct
operation, return to the ON position. Upon performing this step, the display lights up and the inverter's electronics
starts. It is now possible to communicate with the inverter.

11.3. Wiring requirements for connecting ancillary services

• The wiring gauge for ancillary services must be 12 AWG.
• All cables must withstand temperatures greater than +194 °F (+90 °C) and comply with the National
Electrical Code ANSI/NFPA 70.

11.4. Ancillary services connection process

1. To locate the wiring access towards the interior of the unit see section "2.19. Description of cable inlets".
2. Strip the cables.
