ATTENTION
The -F version of the product is not suited for 3-wire connection. It has separate
grounds for power supply and analogue output. Connecting both grounds together
might result in incorrect measurements. Minimum 4 wires are required to connect
-F type sensors.
The -G version is intended for 3-wire connection and features a ‘common ground’.
This means that the ground of the analogue output is internally connected with
the ground of the power supply. For this reason, -G and -F types cannot be used
together on the same network. Never connect the common ground of -G type
articles to other devices powered by a DC voltage. Doing so might cause permanent
damage to the connected devices.
