Test point 1
(Fault voltg. 0V/
housing)
A grounded nominal input
results in anearth circuit.
Therefore ensure that the 0V
and ground line are short and noise immune
To prevent earth circuits,
the measuring voltages should not be grounded.
If it must be grounded,
ensure that the line is short and noise immune.
