Three--phase power to the 9/440HR must be 324-528 V AC, 50/60 Hz.
The drive power is used to supply the drive portion of the 9/440HR the
voltages necessary to power the axis modules and the servo motors.
All power connectors on the 9/440HR power strip accept AWG 12 gauge
solid wire. Refer to local codes for required wire type and gauge.
