ATTENTION: You must ground the DeviceNet shield at only one location.
Connecting the DeviceNet shield to terminal 10 grounds 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 (

WARNING: If you connect or disconnect the DeviceNet cable with power
applied to this module or any device on the network, an electric arc can
occur. This arc could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
