DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 INSULATION CHARACTERISTICS
This isolator is 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 component designates DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 approval for
a 560 V peak working voltage.
