IMPORTANT
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 to one of the Chassis
GND terminals on the XM-720 terminal block and not at
the transducer. Any of the Chassis GND terminals on the
XM-720 terminal block provides a grounding point for the
cable shield.
IMPORTANT
The internal transducer power supply is providing power to
the IEPE accelerometer.
