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

Utility input and output electrical connections

The inverters are equipped with 4 inputs and 2 outputs to enable a number of solutions for interface with more
complex installations.
Figure 10 and Figure 11 show examples of two possible configurations of the inputs and outputs.
For the installer it is sufficient to wire the required input and output contacts and then configure the functions
as necessary (see sections 6.6.13 and 6.6.14).
The +19 [Vdc] power supplies to pins 11 and 18 and J5 (18-pole terminal board) can deliver
a maximum of 50 [mA].
