The incorrect connection of the earth lines to a terminal other than the earth terminal may cause
irremediable damage to the whole equipment.
The incorrect connection of the power supply line to the output terminals intended for the load may cause
irremediable damage to the whole equipment.
5.3
Earth Connection
The earth connection must be made with cable lugs tightened as shown in Figure 2.

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.
