In the same way as with active elements, exercise meticulous care to
interconnect inactive metal elements.
Always make sure that you have a low-impedance interconnection between
metal elements (e.g. large and highly conductive contact surface).
The protective insulating finish on varnished or anodized metal elements must
be pierced or removed. Use special contact washers or completely remove the
finish on the point of contact.
Protect your connecting elements against corrosion (e.g. with a suitable grease)
Interconnect moving chassis ground elements (e.g. cabinet doors) with flexible
ground straps. Always use short ground straps with a large surface (the surface
is decisive for the diversion of high-frequency currents).
