Controller I/O Wiring
Minimizing Electrical Noise
Because of the variety of applications and environments where controllers are
installed and operating, it is impossible to ensure that all environmental noise will
be removed by input filters. To help reduce the effects of environmental noise,
install the MicroLogix 1400 system in a properly rated (for example, NEMA)
enclosure. Make sure that the MicroLogix 1400 system is properly grounded.
A system may malfunction due to a change in the operating environment after a
period of time. We recommend periodically checking system operation,
particularly when new machinery or other noise sources are installed near the
MicroLogix 1400 system.
