Control connections

- We recommend the unilateral screening of all cables for
analog signals to avoid signal distortion.
- Connect the screens of the control cables as follows:
- 8211 - 8214:
On the front FAST-ON connector.
- 8215 - 8218:
On the front metal surface (screw length max.12 mm).
- If the control cables are interrupted (terminal strips, relays),
the screens must be reconnected over the shortest possible
distance.
- Connnect the fixing screw of the setpoint potentiometer to
PE.
