2.2.3.1 Connecting the pressure sensor
The inverter accepts two types of pressure sensor:
1. Ratiometric
2. In current 4 - 20 mA
The pressure sensor is supplied with its own cable, and the cable and connection on the board varies
according to the type of sensor used. Unless otherwise specified, the sensor supplied as standard is
ratiometric.
2.2.3.1.1 Connecting a ratiometric sensor
One end of the cable must be connected to the sensor and the other end to the relative inverter pressure
sensor input, marked "Press 1"; see Figure 5.
The cable has two different terminals with compulsory direction of insertion: connector for industrial
applications (DIN 43650) on the sensor side and 4-pole connector on the inverter side.
2.2.3.1.2 Connecting a 4 - 20 mA current sensor
This is a 2-wire sensor terminating with contacts for DIN 43650 type industrial connectors. The cable
supplied for this type of sensor has a DIN 43650 type industrial connector on one end and two crimped
terminals on two red and white wires on the other. The red termination corresponds to the sensor input and
the white corresponds to the output. The two terminations are inserted on the terminal board of inputs J5 and
connected to the board as shown in Figure 6 using a jumper. Terminals 7 and 8 are respectively the input
and output of the current signal. To use this input with a 2-wire sensor, the power supply must be connected,
and for this reason, terminals 10 and 11 must also be used, as well as a jumper.
