The DVR is connected to an available electrical outlet on a recommended UPS.
The power cord is firmly connected to the DVR’s AC power receptacle.
The power cord is routed appropriately, and is secured out of the way.

1
Plug the AC power cord firmly into the power connector at the bottom of the DVR.
