Mounting Standard Installations
There are many criteria in determining the appropriate enclosure. Some of these
include:
• Environment
• EMC compatibility/compliance
• Available space
• Access/Wiring
• Safety guidelines
Grounding to the Component Mounting Panel
In the example below, the drive chassis ground plane is extended to the mounting
panel. The panel is made of zinc-plated steel that helps to create a proper bond
between chassis and panel.

IMPORTANT Where TE and PE terminals are provided, ground each separately to the nearest
point on the panel with flat braid.
