(c) Fixing the Cable
Fix and ground the cable shield using a piece of conductive metal.
• Example of Cable Clamp
(d) Shield Box
A shield box, which is a closed metallic enclosure, should be used for shielding magnetic interference. The
structure of the box should allow the main body, door, and cooling unit to be attached to the ground. The box
opening should be as small as possible.
