1) Note derating curve ( Section 8.4.4 "Reduced output current due to low 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) Only with "Fan" (standard equipment)
4) for group fuses: maximum fuse size: 30 A
5) Maximum mains short-circuit current, Note: Further restrictions are possible depending on the plug connector which is used (

Section 1.6.1
"UL and CSA approval")
6) "inverse time trip type" according to UL 489
