Chapter 4: Operation

SYSTEM OVERVIEW
This Line-Interactive UPS protects computers, servers, telecom systems, VoIPsystems, security systems, and a variety of electronic equipment from black-outs, brownouts, overvoltages, and surges. The AVR function continuouslycorrects the voltages, in-between the brownout and overvoltage transfer points (90 – 150VAC), to a safe usable level. When the UPS is operating in the AVRmode the audible alarm will remain silent and the AC mode indicator will blinkDuring normal AC operation, the UPS will quietly and confidently protect your system from power anomalies.
The UPS will charge the batteries with the UPS in the on or off position when the UPS is plugged into the wall outlet and there is an acceptable AC voltage present (90 – 150VAC). When a blackout, brownout, or an overvoltage condition occurs; the UPS will transfer to the battery mode, the On Battery indicator will illuminate and the audible alarm will sound once every ten seconds indicating that the commercial power is lost or unacceptable. When the commercial power returns or is at an acceptable level, the UPS will automatically transfer back to the AC mode and start recharging the batteries. During an extended outage when there is approximately two minutes of backup time remaining the audible alarm will sound twice every five seconds. This Low Battery Warning
is informing the user that they should save all open files and turn off their computer. When the batteries reach the predetermined level the UPS will automatically shutdown protecting the batteries from over discharging. Once the commercial power returns and is at an acceptable level the UPS will automatically restart, providing safe usable power to the connected equipment and start recharging the batteries.

Chapter 7: Replacing the Battery

REPLACING THE BATTERY
(QUALIFIED SERVICE PERSONNEL ONLY)
Please read all of the WARNINGS and CAUTIONS before attempting to service the batteries. Typical battery life is 3 to 5 years. Environmental factors do affect battery life. High temperatures, poor utility power, and frequent,short duration discharges have a negative impact on battery life.
WARNING! This UPS contains potentially hazardous voltages. Do not attempt to disassemble the UPS beyond the battery replacement procedure.
This UPS contains no user serviceable parts. Repairs and battery replacement must be performed by QUALIFIED SERVICE PERSONNEL ONLY.
CAUTION: Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes and may be toxic.
CAUTION: Do not dispose of batteries in a fire. The batteries may explode.
The batteries in this UPS are recyclable. Dispose of the batteries properly.
The batteries contain lead and pose a hazard to the environment and human health if not disposed of properly. Refer to local codes for proper disposal requirements or return the battery to the supplier.
CAUTION: The battery system can present a risk of electrical shock. These batteries produce sufficient current to burn wire or tools very rapidly, producing molten metal. Observe these precautions when replacing the batteries:

1. Remove watches, rings, or other metal objects.
2. Use hand tools with insulated handles.
3. Wear protective eye gear (goggles), rubber gloves and boots.
4. Do not lay tools or other metal parts on top of batteries.
5. Disconnect the charging source prior to connecting or disconnecting the battery terminals.
6. Determine if the battery is inadvertently grounded. If the battery is, remove the source of the grounding. Contact with any part of a grounded battery can result in an electrical shock. The likelihood of such shock will be reduced, if such grounds are removed during installation and maintenance.

CAUTION: Replace the batteries with the same number and type as originally installed in the UPS. These batteries have pressure operated vents. These UPSs contain sealed non-spillable maintenance-free lead acid batteries.
