Connect Equipment

battery for a limited period of time when a power outage, or brownout condition occurs. Help to provide protection from

power surges or spikes.

| Connect a computer, monitor and other essential peripheral devices that need to remain on during power outages or AC

problems.

Surge Protection Outlets| Help to provide protection from power surges or spikes.| Connect non-essential peripheral devices (such as printer, scanner, etc.) that do not need to remain on during power outages or AC

problems.

Turn On the Back-UPS

Press the POWER button. It will illuminate green and a single short beep indicates that the Back-UPS is on and helping to provide protection for connected equipment. The Back-UPS battery will charge regardless of whether the Back-UPS is switched on or off as long as it is connected to AC power. The UPS will have full runtime capability after the initial 24-hour charging period, connected to AC power. If the Building Wiring Fault indicator (located on the end near the power cord) is illuminated red, your building wiring may present a shock hazard that should be corrected by a qualified electrician.

Turn Off the Back-UPS
Press the POWER button for at least 2 seconds. At the first beep, release the button and the UPS will turn off. A 2 second delay has been added to mitigate unintentional contact with the POWER button.

Quick Mute
User correctable audible alarms such as On Battery can be temporarily muted. Short press (less than 2 seconds) the POWER button to temporarily mute the audible alarm until the condition is reset. A short double beep confirms that Quick Mute is been activated. Pressing the POWER button for more than 2 seconds will turn off the UPS. Other critical events such as Battery replacement and Charger notification can not be temporarily muted. In such cases, the unit must be turned off.

On Battery Indicator Modes

Press and hold the POWER button till a third beep is heard while the UPS is turned ON, to configure the On Battery Indication mode. At the third beep, POWER button will illuminate red and green alternately. Release the POWER button and the illumination color indicates the mode in which the UPS is in. Press the POWER button again to cycle through each mode. Refer the table below for the details of each mode selection color. Once the mode is selected, wait for 5 seconds to set the configuration.

Mode| Visual Indicator| Audible Indicator| Mode Selection Color
---|---|---|---
Quiet Alarm (default)| The POWER button is solid green and flashes twice every 2 seconds until Low Battery notification where it will flash green in rapid succession.| No alarm until Low Battery notification where the alarm beeps twice every 30 seconds| Flashing green
No Alarm| No alarm while the UPS is On Battery| Flashing red
Full Alarm| Alarm sounds 4 beeps every 30 seconds until Low Battery notification where the alarm beeps every half second. As the UPS shuts down, it sounds one beep every 4

seconds

| Flashing amber

Voltage Sensitivity Adjustment (optional)

The Back-UPS detects and reacts to line voltage distortions by transferring to battery backup power to help protect connected equipment. In situations where either the Back-UPS or the connected equipment is too sensitive for the input voltage level it is necessary to adjust the transfer voltage.

1. Turn off the UPS while connected to a wall outlet.
2. Press and hold the POWER button for 10 seconds. The POWER button will illuminate green and red alternately to indicate that the Back-UPS is in Program mode.
3. The POWER button will flash either green, amber, or red to indicate the current sensitivity level. Refer to the table for an explanation of the transfer voltage sensitivity levels.
4. To exit Program mode wait five seconds and all LED indicators will extinguish. Program mode is no longer active.

LED

Flashes

| Sensitivity Setting| Input Voltage Range (AC Operation)| Recommended Use
---|---|---|---
Green| LOW| 88 Vac to 142 Vac| Use this setting with equipment that is less sensitive to fluctuations in voltage or waveform distortions.
Red| MEDIUM| 92 Vac to 139 Vac| Factory default setting. Use this setting under normal conditions.
Amber| HIGH| 96 Vac to 136 Vac| Use this setting when connected equipment is sensitive to voltage and waveform fluctuations.

| None| Constant tone| Back-UPS is turned off

Troubleshooting

The Back-UPS will not turn on
The Back-UPS is not connected to AC power, there is no AC power available at the wall outlet, or the AC power is experiencing a

brownout or over voltage condition.

| Be sure the power cord is securely connected to the wall outlet, and AC power available at the wall outlet.Where ever applicable, be sure that

the wall outlet is switched on.

The Back-UPS is on, the POWER button illuminates green and red alternately and the unit emits a constant tone
•   The battery is disconnected.

•   The battery is near the end of useful life and should be replaced.

| •   Remove AC power and refer to the section

“Connect the Battery” on page 2.

•   Refer to the section “Battery Replacement” _on page 8_for details.

Connected equipment loses power
A Back-UPS overload condition has occurred.| Remove all nonessential equipment connected to the outlets. Reconnect equipment one at a time to the Back-UPS.

Charge the battery for 24 hours to make sure it is fully charged. If the overload condition still persists, replace the battery.

The Back-UPS battery is completely discharged.| Connect the Back-UPS to AC power and allow the battery to recharge for eight hours.
Connected equipment does not accept the step-approximated sine waveform from the Back-UPS.| The output waveform is intended for computers and peripheral devices. It is not intended for use with motor driven equipment.
The Back-UPS may require service.| Contact SEIT Technical Support.
The POWER button illuminates green and flashes twice every 2 seconds.
The Back-UPS is operating on battery power.| The Back-UPS is operating normally on battery power. Save all open files, and shutdown the computer. When AC power is restored the

battery will recharge.

The POWER button flashes green in rapid succession.
The Back-UPS battery has approximately two minutes of remaining runtime.| The battery is near a total discharge state. Save all open files, and shutdown the computer.

When AC power is restored the battery will recharge.

The Building Wiring Fault LED illuminates red
The building wiring presents a shock hazard that must be corrected by a qualified

electrical.

| Do not operate the Back-UPS. Call a qualified electrician to correct the building wiring fault.
The Back-UPS has an inadequate battery runtime
•   The battery is not fully charged.

•   The battery is near the end of useful life and should be replaced.

| Leave the Back-UPS connected to AC power for eight hours while the battery charges to full capacity.

As a battery ages, the runtime capability decreases. See “Battery Replacement” on _page 8_to order replacement batteries.

The alarm is on with a constant tone; outlets are normal but POWER button illumination is not bright.
The UPS is on AC power but the power of the connected equipment exceeds the rated power of the UPS. If a power disruption occurs the UPS may not be able to power the connected equipment. Power to the outlets will be uninterrupted as long as AC power is present.| Disconnect devices from the UPS until the load is less than the rated output of the UPS.
Problem and Possible Cause| Solution
---|---
The alarm is on with a constant tone and the UPS is off.
The UPS was on battery and the connected load exceeded the rated load of the UPS.| Turn off the UPS. Disconnect all devices. Turn on the UPS and reconnect the devices one at a time.

Wall Mount Installation

• Horizontal installation, use 2 screws 7.63” (194 mm) apart.
• Allow 5/16” (8 mm), of the screw to protrude from the wall.
