Many CyberPower UPS units have two sets of outlets. One set is labeled “Battery/Surge” and one set is labeled “Surge”. The outlets labeled “Battery/Surge” are the outlets that will receive battery power during a power failure. You should plug your computer and monitor into these outlets and any externally powered critical data storage device.
Items such as printers, speakers, scanners, and faxes should be plugged into the outlets labeled “Surge.” These outlets are intended for low priority electronics that are not essential to the PC’s main operation.
