DIN V VDE V 0884-10 (VDE V 0884-10) INSULATION CHARACTERISTICS
These isolators are suitable for reinforced electrical isolation only within the safety limit data. Maintenance of the safety data is ensured by
means of protective circuits.
Note that the * marking on packages denotes DIN V VDE V 0884-10 approval for 846 V peak working voltage.
