3.2.3 Switching the inverter on and off
The inverter switches on and off automatically in AUTO mode. Manual switching on and off is possible in
both TEST mode and AUTO mode.
The control electronics and control panel of the inverter are switched off temporarily in order to save
energy. When the inverter is in this state, it cannot be operated via the panel. However, you can switch
on the control electronics and control panel for maintenance and commissioning purposes. To do so,
open the cabinet door and press the Fast ON button inside the inverter. Once you have switched on the
panel, you can switch the inverter on and off as described below.
To switch off the inverter during operation, briefly press the OFF button on the operator panel (less than 3

3.2.4 Local/Remote selector switch
If the selector switch is set to Local, errors can only be acknowledged locally and the inverter can be
started manually. Remote access is blocked in this switch position.
In the Remote position, errors can also be acknowledged and the inverter started by a plant monitoring
system (such as WinCC). In this position, the inverter can also be operated locally and started manually.
