       ATEX compliant



       The route to EC Declaration of Conformity for ABB low voltage AC drives and motors (ATEX 2014/34/EU)


                Important note:  This flowchart only applies to standard ABB motors
                              Type testing means thermistor relays are not mandatory but to allow protection against stall
                              conditions they are recommended for a safe installation. Use ATEX approved thermistor measurement.
                              ACS880/ACS580 do not require a contactor as the ATEX approved STO can be used to disconnect.
                              ACS880/ACS580 do not require an external PTC relay, as an internal option can be used.
                                                                                                                                       ABB drive,
