Switching the unit on and off
Read the information in Chapter "Safety information (Page 13)" before you switch on the
unit.
Automatic startup
Depending on parameter settings and connection of external control devices, the inverter
can start up automatically when the mains voltage is connected. The motor and coupled
machine can start moving unexpectedly. This can result in death, serious injury or material
damage.
Confirm whether or not your system is capable of automatic starting and, if appropriate,
take measures to ensure personal safety and operational readiness at the driven machine.
Startup
1. If your inverter is supplied with an external control voltage from an external or auxiliary
power supply, then switch this supply on first.
2. Switch on the line voltage.
3. Start up the inverter using the control command <On> or enter the On command via an
external control device (if one is connected).
Shutdown
1. Stop the inverter using the control command <Off> or enter the Off command via an
external control device (if one is connected).
2. If you want to isolate the inverter and bring it into a no-voltage condition, then disconnect
the line supply and any connected external or auxiliary power sources.
