13. Connection of the DCAC connections module

If several inverters are connected to the same transformer, you need to synchronize them. Ingeteam recommends
synchronizing inverters even if connected to independent windings.
The inverters have as standard all the necessary elements for synchronization (electronic card and fiber cables).
This chapter explains the requirements and process for wiring the synchronization.
Read carefully before starting the connection process.
INFO
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.

13.1. Safety instructions for the synchronization connection

DANGER
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 wiring, do not switch the power on 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.
