PRODUCTION DATA
For a device with operational isolation, the continuous working voltage that can be applied across the device in normal operation must be less than 42.5 VRMS or 60 VDC.
Do not use the device as an element of a safety isolation system that exceeds the SELV limit.
If the device is expected to function correctly with more than 42.5 VRMS or 60 VDC applied continuously across the isolation barrier, then the circuitry on both sides of the barrier must be regarded as operating at an unsafe voltage, and further isolation or insulation systems must form a barrier between these circuits and any user-accessible circuitry according to safety standard requirements.
