ATTENTION
Figure 2.27 shows the wiring to the XM-122 module
revision D01 (and later). Earlier revisions of the module do
not support this wiring configuration. Refer to Appendix
D for information about wiring earlier revisions.
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 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 58.
