Warning label on the connection clip
A yellow warning label is attached to each connection clip so that it is easier to find.

The warning label must removed from the connection clip (by pulling it off) if the
connection clip is to remain in the unit (operation on a grounded line supply).
•
The warning label must be removed together with the connection clip if the unit is
operated on a non-grounded line supply (IT system).
