It is not necessary to protect the measuring voltage inputs. But it is recommended to
use a 2A fuse for the supply input (terminals 1 and 3).
The transducer is protected against ESD (electrostatic electricity), and further special
protection against this during the mounting of the transducer is not necessary.
The below diagram illustrates how to connect a TAS-331DG in 2W3 configuration with
a TAS-331DG in 2var3 configuration.
