*This part may also be used in Pollution Degree 3 environments where the rated mains voltage is ≤ 300 V rms (per DIN VDE 0110).
**Refer to the front of the optocoupler section of the current catalog for a more detailed description of VDE 0884 and other product
safety requirements.
Note: Optocouplers providing safe electrical separation per VDE 0884 do so only within the safety-limiting values to which they are
qualified. Protective cut-out switches must be used to ensure that the safety limits are not exceeded.
