The unit requires a 3-phase balanced Mains Supply to provide the power for the
controlled motor, and a 24VDC supply for the internal control circuitry. The unit will
not operate unless the control supply voltage is within the specified limits.
Note: See “Control Terminal Functions” on
concerning the 24VDC
supply specifications.
