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

High humidity can cause moisture to enter the switch. Moisture can cause corrosion of internal components
and degradation of properties such as electrical resistance, thermal conductivity, physical strength, and size.
The switch is rated to withstand from 5- to 85-percent (noncondensing) relative humidity.
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 13,123 feet (0 to 4,000 meters) . If you operate this switch
at a higher altitude (low pressure), the efficiency of forced and convection cooling is reduced and can result
