• b. Pull the battery about half way out, as shown.
• c. Connect the red battery wire to the positive battery terminal.
• d. Push the battery into the battery compartment and re-install the cover, as shown.

Placement / Power

• This UPS is intended for indoor use only.
• Do not operate this UPS in direct sunlight, in contact with fluids, or where there is excessive dust or humidity.
• Be sure the air vents on the UPS are not blocked.
  • Allow adequate space for proper ventilation.
• The battery typically lasts for two to three years. Environmental factors impact battery life. Elevated ambient temperatures, poor quality AC power, and frequent short duration discharges will shorten battery life.
• Connect the UPS power cable directly to a wall outlet. Do not use surge protectors or extension cords.
  • Plug the Back-UPS into a wall outlet, as shown.

Check the Building Wiring Fault Indicator

If the red Building Wiring Fault indicator on the rear panel of the Back-UPS is lit, one of the following conditions exists:

• Open or high resistance ground
• Hot or neutral polarity reversed
• Overloaded neutral circuit

A lit indicator means that a potential shock hazard exists. Improper building wiring should be corrected by a qualified electrician. Do not use the Back-UPS until the condition that caused the fault is corrected.

Note: Improper building wiring will not prevent the Back-UPS from operating, but it will limit its protection capability. It may also result in equipment damage that is not covered by the APC by Schneider Electric Equipment Protection Policy.

Connect Equipment to the Back-UPS

The rear panel of the Back-UPS consists of the following elements:

Battery Back Up Outlets (qty. of 3)
These outlets provide battery back-up, surge protection, and Electro-magnetic Interference (EMI) filtering. In case of power outage, battery power is automatically provided to these outlets. Power (AC or battery) is not supplied to these outlets when the Back-UPS is switched Off. Connect a computer, monitor, and external disk or CD- ROM drive to these outlets.

Surge Only Outlets (qty. of 3).
These outlets are always On (when AC power is available) and are not controlled by the On/Off switch. These outlets do not provide power during a power outage. Connect a printer, fax machine or scanner to these outlets

Black Velcro Straps (qty. of 2 – not shown).
For convenience, two velcro traps have been included and can be used to manage power cords.

Connect the Phone Line to Surge Protection

The telephone ports provide lightning surge protection for any device connected to the telephone line (computer, modem, fax or telephone). The telephone ports are compatible with Home Phoneline Networking Alliance (HPNA) and Digital Subscriber Line (DSL) standards, as well as all modem data rates. Connect as shown.

Status Indicators and Alarms

There are four status indicators (lights) on the front panel of the Back-UPS (On Line, On Battery, Overload, and Replace Battery).

On Line (green) – is lit whenever AC power is powering the Battery Backup outlets.

On Battery (yellow) – is lit whenever the battery of the Back-UPS is powering equipment connected to the Battery Backup Outlets.

• Four Beeps Every 30 Seconds – this alarm is sounded whenever the Back-UPS is running On Battery. Consider saving work in progress.
• Continuous Beeping – this alarm is sounded whenever a low battery condition is reached. Battery run-time is very low. Promptly save any work in progress and exit all open applications. Shutdown the operating system, computer and the Back-UPS
• Overload (red) – is lit whenever power demand has exceeded the capacity of the Back-UPS
• Continuous Tone – this alarm is sounded whenever the Battery Backup outlets are overloaded
• Circuit Breaker – the circuit breaker button located on the rear panel of the Back-UPS will stick out if an overload condition forces the Back-UPS to disconnect itself from AC power. If the button sticks out, disconnect non-essential equipment. Reset the circuit breaker by pushing the button inward.
• Replace Battery (red) – is lit whenever the battery is near the end of its useful life, or if the battery is not connected (see above). A battery that is near the end of its useful life has insufficient run-time and should be replaced.
• Chirps for 1 Minute Every 5 Hours – this alarm is sounded whenever the battery has failed the automatic diagnostic test.

Transfer Voltage and Sensitivity Adjustment (optional)

In situations where the Back-UPS or connected equipment appears too sensitive to input voltage, it may be necessary to adjust the transfer voltage. This is a simple task requiring use of the front panel push button. To adjust the transfer voltage, proceed as follows:

1. Plug the Back-UPS into the AC power source. The Back-UPS will be in a Standby Mode (no indicators lit).
2. Press the front panel push button fully inward for 10 seconds. All indicators on the Back-UPS will flash to acknowledge going into Programming Mode.
3. The Back-UPS will then indicate its current Sensitivity Setting, as shown in the following table.
4. To select the Low Sensitivity setting, press the push button until the yellow indicator is flashing.
5. To select the Medium Sensitivity setting, press the push button until the yellow and red indicators (second and third from the top) are flashing.
6. To select the High Sensitivity setting, press the push button until yellow and both red indicators (bottom three) are flashing.
7. To exit without changing the Sensitivity Setting, press the push button until the green indicator is flashing.
8. Once in Programming Mode, if the push button is not pressed within 5 seconds, the Back-UPS will exit Programming Mode; all indicators will extinguish.
