WARNING!
Connecting terminals carry electrical potential from the
attached sensors/actuators.
Before coming into contact with the connections, ensure
the power is off. Check for any voltages at the connecting
terminals when the attached sensors have varying degrees
of electrical potential or when they have high electrical
potentials with earthing, for example, when measuring elec-
trical current for a mains voltage phase.
Differences in electrical potential between two channels of
a module can not be determined from the measurement
data.
