3–2 System Installation Recommendations
Publication 1747-6.2
The figure below depicts acceptable layouts. Follow the
recommended minimum spacing to allow for convection cooling
within the enclosure. Cooling air in the enclosure must be kept
within a range of 0° C to +60° C (32° F to +140° F).
Important: Be careful of metal chips when drilling mounting holes
for the controllers. Do not drill holes above a mounted
SLC 500 controller.
