NOTE: The ambient upper limit of 35 C is only good up to 1524 m (5000 ft) elevation. There is a 1 C per 304.8 m (1000 ft) derating above 1524 m (5000 ft). So, at 3,048 m (10,000 ft), the upper ambient air temperature limit is 30 C. ● For cabinet installation, ensure adequate cabinet ventilation and ensure that the ambient temperature within the cabinet does not exceed specified limits. ● Never restrict the incoming or outgoing airflow of the workstation by blocking any vents or air intakes as shown in the following figure.
