Electrical connections
The power supply
has to be connected
to
and
.
is considered as
system ground.
The same ground reference has to be used for
the
M-SENSE III unit
and for any connected device!
Unless different transformers are used, special
precautions need to be taken.
PLEASE NOTE! The M-SENSE III signal and power supply
grounds are common.
PLEASE NOTE!
The same ground reference has to be used for
the M-SENSE III unit and for the control system!
