• Where a good ground is available on all units, the best shielding is obtained
by grounding all screens at both ends on all units.
• If the cable is terminated where a good ground is not available a noise
suppression capacitor can be used. The screens of the 2 cables must be
connected as shown in the figure, but not connected to the chassis of the
unit.
