Data Sheet
IEC 60747-5-2 (VDE 0884, PART 2):2003-01 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 IEC 60747-5-2 (VDE 0884, Part 2) approval.
