Mounting Racks
Section 3-3
When mounting the PC in a control panel, mount the Racks to an intermediate
plate. Holes for mounting the Racks to the intermediate plate should be drilled at
intervals shown in the following diagram. Completely ground the intermediate
mounting plates. Use conductor-plated plates to improve noise immunity.
