Environmental Requirements
This section describes the environmental conditions that are prerequisite to installing
the unit, and heat conditions that are generated by normal operation of the unit.
lists the environmental conditions in which the array is designed to
operate.
Humidity
lists the relative humidity ranges of the controller tray.

*
* If you plan to operate a system at an altitude between 3280 feet to 9842 feet (1000 meters to 3000 meters) above
sea level, lower the environmental temperature 3.3˚F (1.7˚C) for every 3280 feet (1000 meters) above sea level.
