Expansion of Basic System with External I/Os

Vertical Mounting
You can also mount the standard mounting rails vertically and then attach the modules one over the
other. Because heat dissipation by convection is less effective in this case, the maximum ambient
temperature allowed is 40° C (104° F).
Use the same minimum clearances for a vertical configuration as for a horizontal configuration.
You must install a clamp (see Catalog SA 2) on the lower end of the PLC tier to hold the modules in
position.
