Temperature Requirements
The switch requires an operating temperature of 32 to 104 degrees Fahrenheit (0 to 40 degrees Celsius). If
the switch is not operating, the temperature must be between –40 to 158 degrees Fahrenheit (–40 to 70 degrees
Celsius).
Humidity Requirements
Buildings in which the climate is controlled by air-conditioning in the warmer months and by heat during the
colder months usually maintain an acceptable level of humidity for the switch equipment. However, if the
switch is located in an unusually humid location, use a dehumidifier to maintain the humidity within an
acceptable range.
Altitude Requirements
This switch is rated to operate at altitudes from 0 to 10,000 feet (0 to 3,048 meters). If you operate this switch
at a higher altitude (low pressure), the efficiency of forced and convection cooling is reduced and can result
in electrical problems that are related to arcing and corona effects. This condition can also cause sealed
components with internal pressure, such as electrolytic capacitors, to fail or to perform at a reduced efficiency.
