The CP1500AVR from CyberPower is a sophisticated uninterrupted power supply or UPS. The unit connects to mid-range to high-end computer systems to provide continuous power in the event of a power failure. A battery within the unit remains at constant charge to take over for the primary power source, if it fails. The UPS also provides line conditioning to help control brownouts and power surges and displays continuous diagnostic information on an LCD screen of the front of the unit. To ensure your CP1500AVR is operating at peak performance, change the batteries when they are worn out.
Switch off and unplug all equipment connected to the CyberPower 1500AVR unit. Switch the unit off and unplug it from the power source. Put on your rubber gloves and shoes.
