DeviceNet Grounding - XM-124 Module Only
The DeviceNet network is fully isolated from the XM-124 power and ground
circuits. Therefore, DeviceNet network can be powered from any suitable
DeviceNet power supply, and must be grounded at that power supply in
accordance with DeviceNet installation instructions.
Switch Input Grounding
The Switch Input circuits are functionally isolated from other circuits. It is
recommended that the Switch RTN signal be grounded at a single point.
Connect the Switch RTN signal to the XM terminal base (chassis terminal) or
directly to the DIN rail, or ground the signal at the switch or other equipment
that is wired to the switch.
