Operating message via signaling contact X3
After a Voltage Protection Module response or in the event of a temperature error, signaling
contact X3 opens and interrupts the inverter system's pulse enable.
The X3 signal contact automatically closes after t > 120 s or after resetting the temperature
switch.

WARNING
Danger to life when the drive automatically starts to run in an uncontrolled fashion
An uncontrolled automatic start of the drive can result in death or severe injury.
• Take measures to prevent the drive starting automatically in an uncontrolled fashion, as
signal contact X3 restores the pulse enable after 2 minutes.
