3. Installation
3.1 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
•The relative humidity should be less than 95 percent, noncondensing.
•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.
3.2 Connecting to Power
Use redundant DC terminal block power inputs or
3.2.1 12-VDC Jack
Step 1: Connect the supplied AC to DC power adapter to the receptacle on the top side of the switch.
Step 2: Connect the power cord to the AC to DC power adapter and attach the plug to a standard AC outlet with the appropriate AC voltage.
3.2.2 Redundant DC Terminal Block Power Inputs
There are two pairs of power inputs for use with redundant power sources. You only need to have one power input connected to run the switch.
Step 1: Connect the DC power cord to the pluggable terminal block on the switch, and then plug it into a standard DC outlet.
Step 2: Disconnect the power cord if you want to shut down the switch.
