In the case of interference from the power supply side the use of appropriate interference
filters is recommended. Bear in mind that the connection between the filter and the unit
should be as short as possible and the metal housing of the filter must be connected to
the earth with the largest possible surface. The cables connected to the filter output must
not be run with cables with interference (e.g. circuits controlling relays or contactors).
Connections of power supply voltage and measurement signals are executed using the
screw connections on the back of the unit’s housing.
