Mounting Racks
The duct work shown in the following diagram is not used for mounting the
Racks. Although optional, this duct work can be used to house the wires from the
I/O Units that run along the sides of the Racks, keeping the wires from becoming
entangled. This figures illustrate the correct way to mount the Racks.
