22 Installing the XM-720 Machine Monitor
Connecting an IEPE Accelerometer
The following figure shows the wiring of an IEPE accelerometer to the
XM-720 back panel.
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.
IMPORTANT
Using the XM Serial Configuration Utility, make certain the
IEPE Power parameter is enabled. Refer to Transducer
Parameters on page 44.
IMPORTANT
A jumper from terminals 5 to 6 on the XM-120/121/122
terminal block is required for channel 1 buffered output. A
jumper from terminals 22 to 6 on XM-120/121/122
terminal block is required for channel 2 buffered output.
Refer to Setting the Buffer Range for the Transducer on
page 20.
