Figure 26 - IEPE Accelerometer and Non-contact Sensor Wiring
Connect Two Accelerometers and a Non-Contact Sensor
The following figure shows the wiring of two IEPE accelerometers and a non-
contact sensor to the terminal base. The IEPE accelerometers are wired to
channel 1 and channel 2. The non-contact sensor is wired to the tachometer
input signal.

WARNING: 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 27 ).
IMPORTANT Make certain the IEPE Power parameter is enabled for both channel 1 and
channel 2 so power is provided to the accelerometers.
Refer to Transducer
Object (Class ID 328H) on page 154 .
IMPORTANT Transducer DC bias is monitored on all signals.
