Notes:
• Do not ground the outer shield of the cable here since it is grounded at the cable entry.
• Keep any signal wire pairs twisted as close to the terminals as possible. Twisting the
wire with its return wire reduces disturbances caused by inductive coupling.
At the other end of the cable, leave the shields unconnected or ground them indirectly via
a high-frequency capacitor with a few nanofarads, eg. 3.3 nF / 630 V. The shield can also
be grounded directly at both ends if they are in the same ground line with no significant
voltage drop between the end points.
