Chapter 1 Install the XM-124 Standard Dynamic Measurement Module
Connect the DeviceNet cable to the terminal base unit as shown.
Connect To Terminal
Red Wire DNet V+ 26 (optional—see note)
White Wire CAN High 23
Bare Wire Shield (chassis) 10
Blue Wire CAN Low 24
Black Wire DNet V- 27
IMPORTANT The DeviceNet power circuit through the XM module interconnect, which is
rated at only 300 mA, is not intended or designed to power DeviceNet loads.
Doing so could damage the module or terminal base.
If the module is configured to operate in Normal mode (fully ODVA compliant),
DNet V+ must be connected.
Refer to Connecting Power on page 30 .
ATTENTION: You must ground the DeviceNet shield at only one location.
Connecting the DeviceNet shield to terminal 10 will ground the DeviceNet
shield at the XM module. If you intend to terminate the shield elsewhere, do
not connect the shield to terminal 10.
ATTENTION: The DeviceNet network must also be referenced to earth at only
one location.
Connect DNet V- to earth or chassis at one of the XM modules.
ATTENTION: The DNet V+ and DNet V- terminals are inputs to the XM module.
Do not attempt to pass DeviceNet power through the XM terminal base to
other non-XM equipment by connecting to these terminals. Failure to comply
may result in damage to the XM terminal base and/or other equipment.
IMPORTANT Terminate the DeviceNet network and adhere to the requirements and
instructions in the ODVA Planning and Installation Manual - DeviceNet Cable
System, which is available on the ODVA website (
http://www.odva.org ).
WARNING: If you connect or disconnect the DeviceNet cable with power
applied to this module or any device on the network, an electrical arc can
occur. This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
