please refer to th
esectionSafe Stop I nstallation.
* Terminal 29 and 37, relay 2 are not included in FC 301.
Very long control cables and analog signals may in rare case s, depending on install ation, result
in 50/60 Hz ground loops due to noise from mains supply ca bles.
If this occurs, you may have to break the shield or insert a 100 nF capacitor be tween shield and chassis.
The digital and analog i nputs and outputs must be connected separately to the FC 300 common
inputs (ter
minal 20, 55, 39) to avoid ground currents from both groups affecting other g roups. For
example, switching on the digital input may disturb the analog inp ut signal.
