Replacing the PLUG
NOTICE
Do not remove or insert a C-PLUG / KEY-PLUG during operation!
A PLUG may only be removed or inserted when the device is turned off.
The device checks whether or not a PLUG is present at one second intervals. If it is
detected that the PLUG was removed, there is a restart. If a valid KEY-PLUG was inserted
in the device, the device changes to a defined error state following the restart.
Inserting the PLUG
1. Turn off the power to the device.
2. Insert the PLUG correctly oriented into the slot.
To ensure this, the housing of the PLUG has a protruding ridge on the long side. The slot
has a groove at this position.
