Table 5: Connecting The 4 - 20 Ma Pressure Sensor; Figure 8: Connecting The 4 - 20 Ma Pressure Sensor - DWT WaCS PWM Serie Instrucciones De Instalación Y Mantenimiento

To enable use, the current pressure sensor must be configured via software, parameter PR in the installer
menu; refer to paragraph 6.5.7.
Multiple inverter connection:
Multiple inverter systems can be set up with a single 4-20mA current pressure sensor, but the sensor must
be wired on all inverters. To connect the inverters, a shielded cable must be used (sheath + 2 wires).
Proceed as follows:

Connect all earthing terminals of the inverters.

Connect terminal 18 of J5 (GND) of all inverters in the chain (use the sheath of the shielded cable).

Connect terminal 1 of J5 (GND) of all inverters in the chain (use the sheath of the shielded cable).

Connect the pressure sensor to the first inverter in the chain.
