DIN V VDE V 0884-10 (VDE V 0884-10) INSULATION CHARACTERISTICS
These isolators are suitable for reinforced isolation only within the safety limit data. Maintenance of the safety data is ensured by
protective circuits. The asterisk (*) marking branded on the package denotes DIN V VDE V 0884-10 approval for a 560 V peak working
voltage.
