The reset depends on the temperature.Figure 21: Motor-starter combination: DS7-SWD and PKE￫ Only PKE trip blocks (PKE-XTUWA-32, PKE-XTUA-…) should beused for motor protection in combination with DS7 soft starters.PKE trip block PKE-XTUCP-… for system protection must not beused in combination with a soft starter DS7! In combinationwith SmartWire-DT this can cause false tripping.M3 ~1L13L25L32T14T26T3L1L2L3PEQ1Q21BG1, BG2M1I > I > I >SWD4-8SF2-5+ 15V
