Table 5: Connecting the 4 - 20 mA pressure sensor
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 ( 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.
