6. Important note: Varistors
Since March 1, 2014, all illuminators of this kind are equipped with additional varistors
serving as a protection against voltage fluctuation and electrical surge. Therefore it is critical
that the illuminators are always properly connected (L1 and N). In case of improper
connection, the varistor will be destroyed!
For this reason and as of March 1, 2014, all illuminators are delivered with a red, bilingual
label attached to the connection cable saying “Caution: Note L1 and N connection!”.
Improper handling of the illuminator will invalidate the warranty!
