Data Sheet
DIN EN 69747-5-2 (VDE 0884 TEIL 2) INSULATION CHARACTERISTICS
These isolators are suitable for reinforced electrical isolation only within the safety limit data. Maintenance of the safety data is ensured by
the protective circuits. The asterisk (*) marking on packages denotes DIN EN 69747-5-2 (VDE 0884 Teil 2):2003-1 approval.
