Turn On the Back-UPS

Press the POWER ON/OFF button located on the front panel of the Back-UPS. The Power On/Off LED will illuminate and a single long beep will be audible to indicate that the Back-UPS is providing protection for the connected equipment.
The Back-UPS battery charges to capacity during the first 10 hours while connected to the utility power. The Back-UPS battery will charge while the Back-UPS is turned on or off as long as it is connected to utility power.
Do not expect the battery to run for its expected capacity during the initial charge period.

Voltage regulation

The Back-UPS will switch to battery power if the utility input voltage level becomes too low or too high, or if the utility power is experiencing voltage fluctuations.

Setup Guide

Setting up the APC BX2000UXI is straightforward.

First, connect the UPS to a wall outlet and set it on a level platform.
Connect other devices to the surge-protected outlets and your essential gadgets to the battery-backed outlets.
To adjust settings including alert preferences and shutdown choices, use the LCD display.
Lastly, use APC's PowerChute software to enable extensive monitoring and control by connecting the UPS to your computer via a USB or serial cable.

Safety and General Information

Inspect the package contents upon receipt. Notify the carrier and dealer if there is any damage.

This UPS is for indoor use only.
Do not operate this UPS in direct sunlight, in contact with fluids, or where there is excessive dust or high humidity.
Do not operate the UPS near open windows or doors.
Be sure the air vents on the UPS are not blocked. Allow adequate space for proper ventilation.
Note: Allow a minimum of 20 cm clearance on all four sides of the UPS.
Environmental factors impact battery life. Elevated ambient temperatures, poor quality utility power, and frequent discharges will shorten battery life. Follow the battery manufacturer recommendations.
Connect the Back-UPS power cable directly to a wall outlet. Do not use surge protectors or extension cords.

Electrical safety

Connection to the branch circuit (mains) must be performed by a qualified electrician.
The protective earth conductor for the UPS carries the leakage current from the load devices (computer equipment). An insulated ground conductor is to be installed as part of the branch circuit that supplies the UPS. The conductor must have the same size and insulation material as the grounded and ungrounded branch circuit supply conductors. The conductor will be green and with or without a yellow stripe.
The UPS input ground conductor must be properly bonded to protective earth at the service panel.
If the UPS input power is supplied by a separately derived system, the ground conductor must be properly bonded at the supply transformer or motor generator set.

Hardwiring safety

Verify that all branch circuit (mains) are deenergized, and locked out before installing cables or making connections, whether in the junction box or to the UPS.
Wiring by a qualified electrician is required.
Check national and local codes before wiring.
Select wire size and connectors according to national and local codes.
Strain relief is required for all hardwiring.
All openings allowing access to UPS hardwiring terminals must be covered. Failure to do so may result in personal injury or equipment damage.
