Note: Wire type not specified by the manufacturer. Some types of wire may not fit within the constraints of the
conduit entry and bend radius inside the drive.
4.2.3 Considerations for Control Wiring
Control wiring refers to the wires connected to the control terminal strip. Select control wiring as
follows:
•
Shielded wire is recommended to prevent electrical noise interference from causing improper operation
or nuisance tripping.
•
Use only UL recognized wire.
•
Wire voltage rating must be at least 300 V for 230 Vac systems. It must be at least 600 V for 460 or
575 Vac systems.
See Table 4-2 below for a summary of power terminal control wiring specifications.
4.3
Input Line Requirements
4.3.1 Line Voltage
See “Power and Current Ratings” on page 4 for the allowable fluctuation of AC line voltage for your
particular X4 model. A supply voltage above or below the limits given in the table will cause the
drive to trip with either an overvoltage or undervoltage fault.
Exercise caution when applying the X4 AC drive on low-line conditions.
