Connection information
WARNING
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 follows 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.
