Attach connector 8 of J5 on the 1st inverter to connector 7 of J5 on the 2nd inverter. Repeat the operation for all inverters
in the chain (use the shielded cable).
• Wire in a jumper between connector 8 and 10 of J5 on the last inverter to close the chain.
Figure 9 provides the wiring diagram for this procedure.

Caution: always use shielded cable to connect the sensors.
To enable use, the current pressure sensor must be configured via software, parameter PR in the installer menu;
refer to paragraph 6.5.7. Otherwise the unit may not run, with error BP1 (pressure sensor not connected).
2.2.3.2 Connecting the flow sensor
The flow sensor is supplied with its own cable. One end of the cable must be connected to the sensor and the other end to the relative
inverter flow sensor input, marked "Flow 1"; see Figure 7.
The cable has two different terminals with compulsory direction of insertion: connector for industrial applications (DIN 43650) on the
sensor side and 6-pole connector on the inverter side.
The body of the flow sensor and ratiometric pressure sensor (0-5V) have the same type of DIN 43650 connector,
and therefore take care to ensure that the correct sensor is connected to the correct cable
.
