What is the ambient temperature operating range for the Flex58 chassis units?

User-supplied enclosure maximum ambient temperature:
Storage:
-25 to +65 C (+13 to 149 F)
Operation:
-10 to +40 C (+14 to 104 F)
To prevent hot spots in the drive controller, use a stirring fan to circulate the air inside the enclosure. The stirring fan should provide a fan flow rate greater than or equal to 105 CFM. The maximum allowable temperature inside the enclosure is 60 C. Derate the current used by 2.2% per each degree C above 40 C for enclosure ambient temperatures. If there is the possibility of condensation, keep the power supply switched on during periods when the motor is not running, or install thermostatically controlled strip heaters.
Internal heat dissipation of the FLEX58 drives is significantly lower than standard panel mounted drives. See the installation guide for additional details.
