INSTALLING YOUR UPS SYSTEM
HARDWARE INSTALLATION GUIDE
1. Battery charge loss may occur during shipping and storage. Before using the UPS, it’s
strongly recommended to charge batteries for five hours to ensure the batteries’ maximum
charge capacity. To recharge the batteries, simply plug the UPS into an AC outlet.
2. When using the included software, connect either the serial or the USB cable between the
computer and the corresponding port on the UPS. Note: If the USB port is used, the serial
port will be disabled. They cannot be used simultaneously.
3. Connect your computer, monitor, and any externally-powered data storage device (Hard
drive, Tape drive, etc.) into the outlets only when the UPS is off and unplugged. DO NOT
plug a laser printer, copier, space heater, vacuum, paper shredder or other large electrical
device into the UPS. The power demands of these devices will overload and possibly
damage the unit.
4. To protect a fax machine, telephone, modem line or network cable, connect the telephone
or network cable from the wall jack outlet to the jack marked “IN” on the UPS and connect
a telephone cable or network cable from the jack marked “OUT” on the UPS to the modem,
computer, telephone, fax machine, or network device.
5. Press the ON/OFF switch to turn the UPS on. If an overload is detected, an audible alarm
will sound and the UPS will continuously emit one beep per second. For resetting the unit,
unplug some equipment from the outlets. Make sure your equipment carries a load current
within the unit’s safe range, (refer to the technical specifications).
6. This UPS is equipped with an auto-charge feature. When the UPS is connected to an AC
outlet, the battery will automatically charge, even when the unit is switched off.
