A CE compliant system must have noise-reducing components as part of
its emergency stop wiring. When connecting E-stop to a 9/Series, place
the ferrite suppressor core as close to the control as possible, as shown in
these drawings:

*Important: If your control has terminal 8,
then connect it to chassis ground. If
terminal 8 is not present on your control,
then this type of grounding is not
necessary.
