How to Install
connecting one end of the screen to earth via a
100 nF capacitor (keeping leads short).
e. Cables for serial communication
Eliminate low-frequency noise currents between
two frequency converters by connecting one end

connected to earth via an internal RC link. Use
twisted-pair cables for reducing the differential
mode interference between the conductors.
