EC motors require 230 V AC 50 Hz supply voltage. 0-10 V DC or PWM signal is
required for for RPM regulation. Multiple EC motors can be wired in parallel in
regards to supply voltage and control signal.
DAMAGE TO THE UNIT!
If multiple motors are installed in one unit, alarm signals must be tapped off for
each motor separately if a control system provided on-site is used. The error
signal is ground-referenced and a serial interconnection of multiple outputs can
cause motor damage. An overload of malfunction-report outputs can also
cause motor damage.
