requirements:

Near an adequate power source. Connect the switch to the appropriate branch circuit
protection according to your local electrical codes.
•
Environmental—switch location—continuous temperature range is from 5° to 40°C
(50° to 104°F).
•
Operating humidity is from 5 to 85 percent non-condensing, continuous.
•
In a dry, clean, well-ventilated, and temperature-controlled room, away from heat
sources such as hot cooling vents or direct sunlight.
•
Away from sources of severe electromagnetic noise.
•
Positioned in a rack or cabinet, or on a desktop with adequate space in the front, back,
and sides for proper ventilation and access.
•
Install the switch in Information Technology Rooms in accordance with Article 645 of
the National Electrical Code and NFPA 75.
