Whenever possible, use wiring conduit to hold the I/O wiring. Standard wiring
conduit should be used, and it should be long enough to completely contain
the I/O wiring and keep it separated from other cables.

Mounting Requirements
The system consists of from one to four CPUs and, if more than one CPU is
used, a Link Adapter. The Units may be mounted horizontally or vertically, as
desired. Do not mount a Unit on its side. The Unit should be mounted with
the printing on the front panel oriented as it would normally be read. The PC
can be mounted using DIN Track or mounted directly to any sturdy support
meeting the environmental specifications listed in Appendix B Specifications.
Track Mounting
The PC may be mounted using DIN Track if desired. Use DIN Track 35 mm
wide. There is a groove on the back of the Unit that is used to attach it to the
DIN Track. When mounting to DIN Track, be sure to remove the mounting
screws.
