Mounting Requirements

Your installation must meet the following requirements for cooling and cabling clearance.

Allow 25.4 mm (1.00 in.) on all sides of the cRIO-903x for air circulation, as shown in the following figure.

Allow the appropriate space in front of C Series modules for cabling clearance, as shown in the following figure. The different connector types on C Series modules require different cabling clearances. For a complete list of cabling clearances for C Series modules, visit ni.com/info and enter the Info Code crioconn.

Measure the ambient temperature at each side of the cRIO-903x, 63.5 mm (2.50 in.) from the side and 38.1 mm (1.50 in.) forward from the rear of the cRIO-903x, as shown in the following figure.
