Environmental
Temperature
Operating -40 °C to 70 °C
Storage -40 °C to 85 °C
Notice If the ambient temperature is 56 °C to 70 °C, you must mount the chassis
on a thermally conductive material. For information about how mounting
configuration can affect the accuracy of C Series modules, visit ni.com/info and

enter the Info Code rdcriotemp. Measure the ambient temperature at each side of
the CompactRIO system, 63.5 mm (2.5 in.) from the side, and 25.4 mm (1 in.) from
the rear cover of the system
Ingress protection IP40
Operating humidity 10% RH to 90% RH, noncondensing
Storage humidity 5% RH to 95% RH, noncondensing
Pollution degree 2
Maximum altitude 5,000 m
Indoor use only.
Hazardous Locations
Explosive atmospheres rating Ex nA IIC T4 Gc
CCC certificate number 2021312310000318

Caution Do not remove modules unless power has been switched off or the area is
known to be nonhazardous.
Caution Substitution of components may impair suitability for Zone 2.
Caution You must make sure that transient disturbances do not exceed 140% of
the rated voltage.
Caution The system shall only be used in an area of not more than Pollution
Degree 2, as defined in IEC/EN 60664-1.
Caution The system shall be mounted in a CCC-certified enclosure with a
minimum ingress protection rating of at least IP54 as defined in GB3836.1.
Caution The enclosure must have a door or cover accessible only by the use of a
tool.

Installing the Controller on the Chassis
Complete the following steps to install the controller on the chassis.
1. Make sure that no power is connected to the controller or the chassis.
2. Align the controller with the chassis.
3. Slide the controller onto the controller slot on the chassis. Press firmly to ensure the
chassis connector and the controller connector are mated.
4. Using a number 2 Phillips screwdriver, tighten the two captive screws on the front of the
controller to 1.3 N · m (11.5 lb · in.) of torque.
Installing C Series Modules
Verify that power is not connected to the I/O connector(s) on the C Series module.
Removing C Series Modules
Verify that power is not connected to the I/O connector(s) on the C Series module before you
remove a module from the chassis.
