The CyberPower CP685AVR / BF685 and CP800AVR / BF800 are uninterruptible power supply (UPS) systems designed to provide comprehensive power protection for electronic devices. These units safeguard against inconsistent utility power, offering surge protection and battery backup to ensure continuous operation during power outages and voltage fluctuations.
The primary function of these UPS units is to deliver stable and clean power to connected equipment. They incorporate Automatic Voltage Regulation (AVR) to automatically adjust incoming utility voltage to a consistent, computer-safe 110V/120V level. This protects sensitive electronics from damaging voltage sags (brownouts) and surges. In the event of a complete utility power loss, the UPS seamlessly switches to battery backup, providing temporary power to allow users to save open files and safely shut down their computer systems. The units also feature robust surge protection, rated at 890 Joules, to shield connected devices from power spikes and electrical noise.
The UPS units are designed for straightforward installation and operation. Upon receipt, it is recommended to recharge the internal batteries for at least 16 hours to ensure maximum charge capacity, although the unit can be used immediately.
For setup, users connect their computer, monitor, and any externally powered data storage devices (such as Zip drives, Jazz drives, or tape drives) to the battery power-supplied outlets. Peripheral equipment like printers, scanners, and speakers should be plugged into the full-time surge protection outlets. It is crucial to avoid plugging high-demand electrical devices such as laser printers, paper shredders, copiers, space heaters, or vacuums into the UPS, as this can overload and potentially damage the unit.
Network connections can also be protected by connecting a network cable from the wall jack to the UPS's "IN" jack, and then another network cable from the UPS's "OUT" jack to the network device. The UPS itself plugs into a standard 2-pole, 3-wire grounded wall outlet. Users must ensure the wall outlet is protected by a fuse or circuit breaker and does not serve other high-demand equipment. The use of extension cords, outlet strips, or surge strips with the UPS is prohibited by the warranty.
Once connected, the unit is turned on by pressing the power switch, which illuminates the power-on indicator light and triggers a single beep. If an overload is detected, an audible alarm will sound with a long beep. To rectify this, the UPS should be turned off, and at least one piece of equipment should be unplugged from the battery power-supplied outlets. After waiting 10 seconds and ensuring the circuit breaker is depressed, the UPS can be turned back on.
The units include four battery-powered/surge-protected outlets, ensuring uninterrupted operation during power failures, and four full-time surge suppression outlets for continuous protection. A "Power On Indicator" LED illuminates when the utility condition is normal and the UPS is providing surge-free power. An "Electrical Wiring Fault Indicator" LED warns users of wiring problems, such as bad ground, missing ground, or reversed wiring, advising them to disconnect all equipment and have an electrician inspect the outlet.
Communication protection ports are integrated to safeguard standard modem, fax, telephone lines, broadband networks, or Ethernet connections. A circuit breaker, located on the side of the UPS, provides overload and fault protection.
For computer communication, the UPS features USB and DB-9 serial ports, allowing connection to a PC. These ports enable the UPS to communicate its status to the included PowerPanel™ Personal Edition software, which automatically saves open files and shuts down the computer during a power loss. The software is compatible with Windows® 2000 and Windows® XP.
The units also offer a vertical use stand, allowing them to be placed on their end, preferably next to a wall. Four outlets are spaced to accommodate AC power adapter blocks without blocking adjacent outlets. Coax/Cable/DSS surge protection ports are included to protect cable modems, CATV converters, or DSS receivers.
To maintain optimal battery charge, the UPS should remain plugged into an AC outlet at all times. For extended storage, the unit should be covered and stored with a fully charged battery, with recharging recommended every three months to ensure battery life.
Battery replacement is a key maintenance feature. Users are advised to follow strict safety precautions, including removing metal objects, using insulated tools, avoiding contact with battery terminals, and wearing rubber gloves. The replacement process involves turning off and unplugging all connected equipment and the UPS itself, then turning the UPS upside down to access and remove the battery compartment cover. After disconnecting the old battery wires, the new battery is installed by connecting the red wire to the positive terminal and the black wire to the negative terminal. The battery compartment cover is then reattached, and the unit is recharged for 4-8 hours. Old batteries are considered hazardous waste and must be disposed of properly, with most retailers collecting used lead-acid batteries for recycling.
Troubleshooting guidance is provided for common issues. If full-time surge protection outlets stop providing power due to a tripped circuit breaker, users should turn off the UPS, unplug equipment, wait 10 seconds, reset the breaker, and turn the UPS back on. If the UPS does not perform as expected runtime, the battery may not be fully charged (requiring recharging) or may be worn out (requiring replacement). If the UPS does not turn on, it may be due to the on/off switch design (requiring a 10-second wait before turning back on), the unit not being connected to an AC outlet, a worn-out battery, or a mechanical problem. If the PowerPanel™ Personal Edition software is inactive, users should check the USB/serial cable connection, ensuring it is connected to the correct port on both the UPS and the computer, and that the correct CyberPower cable is used.
