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.
