Installation
This chapter gives step-by-step instructions about how to
install the switch:
Selecting a Site for the Switch
As with any electric 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 ambient temperature should be between 0 to 45
degrees Celsius.
- The relative humidity should be less than 90 percent,
non-condensing.
- Surrounding electrical devices should not exceed the
electromagnetic field (RFC) standards.
- Make sure that the switch receives adequate ventilation.
Do not block the ventilation holes on each side of the
switch or the fan exhaust port on the rear of the switch.
- The power outlet should be within 1.8 meters of the
switch.
