Connect the Battery

The Back-UPS is shipped with one battery cable disconnected. Remove the “Stop!

Connect the Battery” label that covers the outlets. Prior to connecting any equipment

to the unit, connect the battery cable to the unused battery terminal. It is normal for

small sparks to be seen when the battery cable is connected to the battery terminal.

Wall Mount Installation

• Horizontal installation, use 2 screws 5.0" (127 mm) apart.

• Vertical installation, use 2 screws 4.3" (110.4 mm) apart.

• Allow 5/16" (8 mm), of the screw to protrude from the wall.

Connect Equipment

Battery Backup + Surge Protection Outlets

Battery backup outlets provide protection to connected equipment when the

Back-UPS is turned on and connected to utility power.

Battery backup outlets receive power from the Back-UPS for a limited period of time

when a power outage, or brownout condition occurs.

Battery backup outlets provide protection from power surges or spikes.

Connect a computer, monitor and other peripheral devices to the outlets.

Surge Protection Outlets

Surge protection outlets provide protection to connected equipment when the

Back-UPS is connected to utility power, and is switched on or off.

Surge protection outlets provide protection from power surges or spikes.

Connect a printer, scanner or other peripheral devices that do not need to remain on

during power outages, or utility problems to the surge protection outlets.

Connect telephone line

The Back-UPS protects equipment connected to a telephone line from power surges

when connected through the Back-UPS coaxial connectors.

Turn On the Back-UPS

Press the POWER ON button located on the top of the Back-UPS. The Power On/

Replace Battery LED will illuminate and a single short beep will be audible to

indicate that the Back-UPS is providing protection for connected equipment.

The Back-UPS battery charges fully during the first 16 hours while connected to

utility power. The Back-UPS battery will charge while the Back-UPS is switched on

or off and is connected to utility power. Do not expect full battery run capability

during the initial charge time.

If the red Building Wiring Fault LED located on the side of the Back-UPS

illuminates, do not operate the Back-UPS. Have a qualified electrician correct the

building wiring fault.

Voltage Sensitivity Adjustment (optional)

The Back-UPS detects and reacts to line voltage distortions by transferring to battery

backup power to 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. Connect the Back-UPS to a wall outlet. The Back-UPS will be in Standby mode,

no indicators will be illuminated.

2. Press and hold the ON/OFF button for 10 seconds. The OnLine LED will

illuminate alternately green-amber-red, to indicate that the Back-UPS is in

Program mode.

3. The Power On/Replace Battery LED 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 select LOW sensitivity, press and hold the ON/OFF button until the LED

flashes green.

5. To select MEDIUM sensitivity, press and hold the ON/OFF button until the LED

flashes red.

6. To select HIGH sensitivity, press and hold the ON/OFF button until the LED

flashes amber.

7. To exit Program mode wait five seconds and all LED indicators will extinguish.

Program mode is no longer active.

This unit is intended for indoor use only.

Do not operate this unit in direct sunlight, in

contact with fluids, or where there is

excessive dust or humidity.

Connect the Back-UPS power cord directly to

a wall outlet. Do not use a surge protector or

an extension cord.

My ES 350 's LED is flashing red with a constant tone. The battery has only 3V. Is this normal or should the UPS beeps instead?

I have installed a new battery but when plugged in and the button is depressed for 10+ seconds the light does not come on. Do you think it is the unit?
