Fully disconnecting the device from the line voltage
Risk of fire and electric shock
The on/off button and on/off switch do not fully disconnect the device from the line voltage.
If the device is switched off with the on/off switch, the electric shock hazard and fire hazard
remain, for example, if the device or connection cables are damaged or if the device is
used improperly.
Always fully disconnect the device from the line voltage, as described below, before
performing work on the device or when the device will not be used over an extended period
of time.
If the device was not installed in a control cabinet:
● Shut down the operating system and unplug the power plug from the rear of the device.
If the device was installed in a control cabinet:
● Shut down the operating system and switch the AC circuit breaker to "Off".
The device is switched off and fully disconnected from the line voltage. No trickle current is
flowing.
Hardware reset
You can perform a hardware reset to switch off the device when the operating system no
longer responds to input from the keyboard or mouse. The operating system is not safely
shut down in this case.
