1) Pay attention to derating curve (

section 8.4.4 "Reduced output current due to line voltage").
2) FLA – Full-load current , maximum current for the entire line 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 short-circuit current in the grid
6) The use of an SK TU4-MSW(-…) module, limits the permissible short circuit in the grid to 10 kA
7) "inverse time trip type" in acc. with UL 489
a) 6.7 A when using a suitable fan
