Thermal Performance and Considerations
These units are rated for operation from -40°C to +75°C when the proper thermal considerations are taken into
account. Please refer to the following information to maximize the performance of these units when they are
operated under extreme temperatures.
Hot Operating Conditions
These units have many modes of operation which can cause the power consumption and corresponding heat
dissipation to vary greatly. This factor, along with others, can affect the performance and longevity of the unit.
These units are rated for operation up to +75°C in typical applications where the wireless communication (cellular
and/or Wi-Fi) is low to moderate.
The maximum temperature applies to the ambient which is defined as the temperature of the air immediately
surrounding the unit. Though operating with an ambient temperature up to +75°C is allowed, for best performance
and longevity it is recommended to keep the ambient air temperature at or below 60°C if possible. Reduced
wireless performance may occur when operating above +60°C.
Please note that the +75°C ratings are based on low to moderate wireless communications. If your wireless
communications are typically high or frequent then the maximum ambient operating temperature may be reduced.
Here are some recommendations to reduce the ambient temperature around the unit for optimal performance and
to prevent temperature related issues:
•
Make sure other hot devices are not mounted immediately adjacent or below the unit.
•
Use a DIN rail spacer between adjacent units so heat cannot transfer due to direct contact.
•
Use a cabinet fan or other enclosure cooling technique.
