Connections
For effective protection from electromagnetic noise, all signal cables
must be shielded, or located on conductive trays or in conduits.
Strip wires to  mm from the ends. Use a suitable ferrule for
multistranded wires (do not solder).

Input signals
The PTX800D input circuits are rated category II (suitable for
measurements performed on the low voltage installation). They may
safely be floating with respect to local ground (i.e., subject to common
mode voltages) up to 50 V DC.
