A restricted access area is one in which service personnel can only gain access using a special tool, lock, key or other means of security and access is controlled by the authority responsible for the location.
Ensure that the area where you install your S4048–ON switch meets the following safety requirements:
  • Near an adequate power source. Connect the switch to the appropriate branch circuit protection as defined by your local electrical codes.
  • Environmental temperature between 32° to 113°F (from 0° to 45°C).
  • The switch operating ambient temperature range is from 10° to 35°C (from 50° to 95°F).
  • Operating humidity is from 5 to 85 percent non-condensing.
  • Storage humidity is from 5 to 95 percent non-condensing.
  • In a dry, clean, well-ventilated and temperature-controlled room, away from heat sources such as hot air 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, rear, and sides of the S4048–ON for proper ventilation and access.
