Figure 63: EN Auxiliary Power Supply Wiring Diagram
As shown in Figure 63, the auxiliary logic power connector is accessed through a plastic
punch-out tab located on top of the drive that reads "BUS/AUX". The auxiliary logic power
for each EN drive must be individually transformer isolated from the AC supply. The voltage
range is 127 to 373 VDC, at 21 Watts. This can be accomplished by isolating, rectifying and
filtering 90 to 264 VAC.
