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 XM-123
terminal base and not at the transducer. Any convenient
Chassis terminal may be used (see Terminal Block
Assignments on page 18).
IMPORTANT
Make certain the IEPE Power parameter for channel 1 is
enabled so power is provided to the accelerometer. Refer
to Channel Transducer Parameters on page 50.
IMPORTANT
The internal transducer power supply is providing power to
the non-contact sensor.
