Figure 2.28 Two IEPE Accelerometers and a Non-Contact Sensor Wiring
Connecting a Velocity Sensor and Two Non-Contact Sensors
Figure 2.29 shows the wiring of a velocity sensor and two non-contact sensors
to the terminal base unit. The velocity sensor is wired to channel 1. The first
non-contact sensor is wired to channel 2, and the other non-contact sensor is
wired to the tachometer input signal.

IMPORTANT
Figure 2.29 shows the wiring to the XM-122 module
revision D01 (and later). If you have any earlier revision of
the module, refer to Appendix D for wiring information.
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).
