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.
