-34C to +74C (100LFM or more Fan or Blower equipped Enclosure
Operating)
-40C to +85C (Type Tested to +85C for 16 hours)
Note: If the unit is powered on at subzero temperatures it could take up to 12
minutes to complete the booting process. This is due to the internal heaters
that heat up the devices to safe operating temperature.
