Hi all,

As far as I am concerned, 89Cxx series have great tendency to be SW crashed when working under electricaly dirty environments. Even an irrelevant circuit breaker or a contactor under heavy load next to your system run by 89Cxx, can easily be reason to a crash for your circuit.

My question is, what preventive methods or precoutions should be taken at your circuit for a safe operation while working at dirty environments.

Thanks to all returns.
