Operating a Basic Line Module from an insulated network (IT system)
When the device is operated on an isolated-neutral network (IT system), the connection
bracket to the noise suppression capacitor must be removed (e.g.: see "1" in figure below).
The interface overview in the section "Interface description" shows the position of the
connection bracket on the different frame sizes.
