HARDWARE INSTALLATION
1. Your new UPS may be used immediately upon receipt.
However, recharging the battery for at least four hours is
recommended to insure that the batteries are fully
charged. Charge loss may occur during shipping and
storage. To recharge the battery, simply leave the unit
plugged into an AC outlet. The unit will charge in both the
on as well as the off position.
2. If you wish to use the software, connect the
enclosed serial interface cable to the serial port
on the UPS and an open serial port on the
computer. If you would like to use USB interface,
please connect the USB adapter with the serial
cable then connect the USB adapter to your
computer.
3. With the UPS unit off and unplugged, connect your
computer, monitor, and any other devices into the battery
power supplied outlets. 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.
