2.2.4 Voltage Inputs
690V Inputs (Standard):
690V inputs are usually used with direct connection. Use any of the
seven wiring configurations shown in Figures 2-5 through 2-11.
120V Inputs (Option U):
120V inputs usually implies use of a potential transformer (PT).
The PT requires use of any of the four wiring configurations shown
in Figures 2-7 through 2-10.
