The M4M voltage inputs have a high impedance which decreases power consumption and increases
security due low current flow in the voltage input circuit. However, if the voltage input wirings are
floating, i.e. not connected to a voltage source, the wires may work as an antenna to the surroundings
electric fields which can create a perceived floating voltage. The M4M will not show this floating voltage
in case it is below 40V (below the Voltage measurement range) and in case of a three phase system
with measuring current below starting current (below current measurement range). In all other cases
of floating voltage the M4M display may show a voltage bigger than zero, which depends on installation
conditions. This behavior does not affect the reliability of the M4M in normal conditions with a connected
load.
