Connection of the Differential Pressure Sensor
The MCE-22/C accepts two types of differential pressure sensor: ratiometric with full scale value 4 bar or ratiometric with full scale
value 10 bar. The cable must be connected at one end to the sensor and at the other to the pressure sensor input provided on the
inverter, marked "Press 1" (see Figure 3)
The cable has two different ends with obligatory direction of connection: connector for industrial applications (DIN 43650) on the sensor
side and 4-pole connector on the MCE-22/C side.
