Preparing the Site

•

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).

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 95-percent (nonoperating) and 5- to 90-percent (operating) 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.
