16.1. Safety instructions for the AC connection

DANGER
Before performing the connection, check there is no voltage in the AC wiring.
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 AC 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.
There is a risk of fire when using wiring gauges with a lower permissible current than the maximum possible
current.
Use the Personal Protective Equipment specified in section "Personal Protective Equipment".
CAUTION
In order to prevent damage to the unit, it is mandatory to install the required wiring for the emergency trip
system in the Medium Voltage switchgear, or the equivalent protection upstream of the inverter, is operating.
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.

16.2. Connection area

There are different types of AC connection relative to the installation's requirements. In all these configurations the
power supply can be found in the right of left side of the inverter, depending on the client's requirements in the
order.
The order of the busbars for phases R, S, T for all configurations is the same as that specified in the following
figures, depending on whether they are right-hand side or left-hand side connections.
