Step 2: Mounting the Rack
Screw the rack to the base.
Is the base material a grounded metal plate or a grounded equipment plate?
If so: Establish a low-impedance connection between rack and base material.
With painted and anodized metals, for example, use a suitable contact agent or
special contact washers.
If not: No special measures are required.
