This is the guaranteed value for startup. (3-phase only)
A. 3-Phase (340 VAC or over to 576 VAC or lower)
For less than 340 VAC, it is possible to use with output voltage at
28.5 VDC or lower and load rate 60% or lower.
B. 2-Phase (380 VAC or over to 576 VAC or lower, and output voltage
26.4 VDC or lower)
C. 2-Phase (360 VAC or over to 380 VAC or lower, and output voltage
26.4 VDC or lower)
For 340 VAC or over to less than 360 VAC, it is possible to use with
output voltage at 26.4 VDC or lower, and whichever is the smaller of
the load rate 60% or lower or the value of C.

F. 2-Phase (Over 480 VAC to 576 VAC or lower)
For 340 VAC or over to less than 380 VAC, it is possible to use with
output voltage at 26.4 VDC or lower, and whichever is the smaller of
the load rate 60% or lower or the value of F.
