1) Note derating curve (

Section 8.4.4 "Reduced output current due to mains voltage").
2) FLA – Full Load Current, maximum current for the entire mains voltage range as stated above (380 V – 500 V) according to UL/CSA
3) FLA (S1-45°C), FLA motor mounting: relates to a motor with fans
4) SK 21xE and SK 23xE devices: For use of safe functions (functional safety: STO and SS1) the restrictions regarding the permissible temperature
range according to BU 0230 must be noted.
5) Maximum permissible mains short circuit current
6) The use of an SK TU4-MSW(-…) module, limits the permissible short-circuit in the mains to 10 kA
7) "inverse time trip type" in acc. with UL 489
