Is it possible to use ATS42/22 with a category 4 circuit?
ATS22 and ATS48
All serial numbers for ATS22 and ATS48
We do not have any safety features implemented in ATS22/48, no any safety validated scheme, certificate etc.
However, one can use a typical category 4 safety scheme where the ATSxx is connected just before the motor:
Safety is based on safety elements (relays, contactors, safety PLC...) and the ATSxx operates like a motor.
ATSxx does store any energy (no capacitors) so safety contactors are doing safety cut-off the ATSxx+motor.
