Note:
This module contains a circuit to protect the DeviceNet power supply from short circuits
in an attached sensor or sensor cable. If you connect a sensor while the module is
powered, the surge current produced by the sensor can cause the module to fault. This
operation is normal. If this occurs, reset the module (page 25).
