Transducer Grounding
Make certain the transducers are electrically isolated from earth ground. Cable
shields must be grounded at one end of the cable, and the other end left
floating or not connected. It is recommended that where possible, the cable
shield be grounded at the XM terminal base (Chassis terminal) and not at the
transducer.
DeviceNet Grounding
The DeviceNet network is functionally isolated and must be referenced to
earth ground at a single point. XM modules can not be used with an external
DeviceNet power supply. Connect DeviceNet V- to earth ground at one of
the XM modules, as shown in the illustration below.
Grounded DeviceNet V- at XM Module
For more information on the DeviceNet installation, refer to the ODVA
Planning and Installation Manual - DeviceNet Cable System, which is
available on the ODVA web site (http://www.odva.org).
ATTENTION
Use of a separate DeviceNet power supply is not permitted. See Application
Technique “XM Power Supply Solutions”, publication ICM-AP005A-EN-E, for
guidance in using XM with other DeviceNet products.
