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 (S1-40°C)
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) Fan cooling, temperature-controlled: ON= 55°C, OFF= 50°C,
After-run time when 50°C limit undershot and enable removed: 2 minutes
6) Maximum permissible short-circuit current in the grid
7) "inverse time trip type" in acc. with UL 489
