ATTENTION: You may ground the cable shield at either end of the cable.
Do not ground the shield at both ends. Recommended practice is to
ground the cable shield at the terminal base and not at the transducer.
Any convenient chassis terminal may be used (see
Terminal Block
Assignments on page 27).
IMPORTANT The module does not power the sensor. It measures only the input voltage.
