All interfaces are realized with altogether 4 Phoenix combicon connectors, type MSTBT 2,5/ 3-ST.
By this an easy replacement of the unit is possible. Use 24VDC as control signal. ATTENTION: As
a PWM (puls width modulation) is used to realize the speed control, it is absolutely necessary
to use shielded cables for connecting the motors in order to prevent disturbance due to
harmonic waves. Take care that the shielding of the cable is connected only on one side of the
cable: either on driver or on motor side. This is to prevent ground loops. We recommend to
connect the shield to 'PE'-Pin of the DC-driver and isolate shield on motor side. The following
table shows the pin description of the motor drivers:

The circuit breakers disconnect the mains from the units build to the control cabinet. Every circuit
breaker is labeled with the unit it is connected to.
Warning: In case of switching off all the circuit breakers it is still voltage available at the mains
terminals!
