Guidelines for RF grounding

Grounding the casing in a cubicle
Connect the rear of the casing (individual unit or rack) to the
hinged frame in the cubicle by a braided copper strip (at least
2 cm wide) which should be as short as possible. To prevent cor-
rosion, a Cupal disc (copper-plated aluminium) must be inserted
between aluminium and copper parts.
Connect the ground rail in the cubicle to the plant ground.
The interconnecting cable must have at least the same gauge as
the ground rail in the cubicle.
