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.
