VDE 0884 INSULATION CHARACTERISTICS
This isolator is suitable for basic electrical isolation only within the safety limit data. Maintenance of the safety data must be ensured by
means of protective circuits.
An asterisk (*) on the physical package denotes VDE 0884 approval for 560 V peak working voltage.
