as with any electronic device, you should place the switch where it will not be subjected to extreme temperatures, humidity, or electromagnetic interference. specifically, the site you select should meet the following requirements:

    the room temperature should be between 32 and 104 degrees fahrenheit (0 to 40 degrees celsius).

    the relative humidity should be less than 90 percent, non?condensing.

    surrounding electrical devices should not exceed the electromagnetic field (rfc) standards for iec 801?3, level 2 (3v/m) field strength.

    make sure that the switch receives adequate ventilation. do not block the ventilation holes on the side of the switch or the fan exhaust port on the rear of the switch.

    the power outlet should be within 6 feet (1.8meters) of the switch.
