The DC power and AC power of the device will back each other up immediately when one of the power sources fails.
Before connecting the DC power cable to the DC power input socket on the Switch, the DC power cable must be
properly connected to DC source at your facility by a qualified
licensed electrician. The DC power cable’s wire gauge
must be 18 AWG. Connect the DC power cable to a DC main circuit breaker rated no greater than 15 A.
If you are installing a DC-powered switch, you must ground the chassis before connecting the Switch to the DC power
source, using the following instructions:
Use a minimum of 18 AWG stranded copper wire. The wire should be long enough to reach from the Switch to
the facility ground point.
Torque screwdriver with a 1/4-inch flat blade.
Ground additional hardware appropriately to the earth ground connection at your site.
