Voltage Rating
Easy-Start ES Used For
Voltage Rating Transformer Connections
208/230/460 460V
380/415 380V
If the incoming line voltage is different than the
factory connected rated voltage shown in
previous paragraph, reconnect the multi-voltage
transformer primary and secondary as follows for
Cutler-Hammer transformers:
Primary

oltage Connection Connection Jumper Voltage
208 VAC H5 X3 H1 to H3 & H2 to H5 110 VAC
380 VAC H4 X3 H2 to H3 120 VAC
415 VAC H5 X3 H2 to H3 120 VAC
460 VAC H4 X2 H2 to H3 115 VAC
230 VAC H4 X2 H1 to H3 & H2 to H4 115 VAC
The primary to FU1 is factory connected to H1.
One secondary lead is factory connected to X1.
The X1 and H1 connections remain the same for all line voltages.
