a. The rp54xx has been designed to operate within the above specific temperature and relative
humidity operational limits. In general, operating any electronic equipment within the
recommended ranges of temperature and humidity will produce optimal reliability.
b. Temperature ranges stated above are at sea level. Maximum operating temperature is
derated (reduced) by 2
meters.
Operating ranges refer to the ambient air temperature and humidity measured at the cabinet
