Clearance Requirements for Installing a CPU 210
Use the following guidelines as you plan your installation:
S The CPU 210 is designed for natural convection cooling. You must provide a clearance
of at least 25 mm (1 inch), both above and below the units, for proper cooling. See
Figure 1-4. Continuous operation of all electronic products at maximum ambient
temperature and load will reduce their life.
S If you are installing a CPU 210 on a panel, you must allow 75 mm (2.9 inches) for the
minimum panel depth. See Figure 1-4.
S Be sure to allow enough space in your mounting design to accommodate the I/O wiring
connections.
