36 Installing the Absolute Shaft Module
Connect the DeviceNet cable to the terminal base unit as shown.
The devices are shipped from the factory with the network node address
(MAC ID) set to 63. The network node address is software settable. You can
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.
To preclude this possibility, even unintentionally, it is
recommended that DeviceNet V+ be left unconnected.
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 web site (http://www.odva.org).
