1		Connect Battery
		For safety, the Back-UPS ES is shipped with one battery wire disconnected. The UPS will not operate until the wire is connected to the touch-safe
		battery terminal. NOTE: Small sparks may occur during battery connection. This is normal.

1	Turn the Back-UPS ES over and press in the
	release tab. Slide the plastic battery cover

off of the Back-UPS.

2	Connect the battery wire firmly to the
	battery terminal.

3	Insert the battery back into the compartment.
	Slide the plastic battery cover until the release

tab locks into place.

Connect Equipment
	Battery Back-up + Surge Protection

These outlets are powered whenever the Back-UPS ES is switched ON. During a power outage or other utility problems (brownouts, over-voltages), these outlets will be powered for a limited time by the Back-UPS ES. Plug your computer, monitor, and other peripheral devices into these outlets.

Surge Protection

These outlets provide full-time protection from surges even if the Back-UPS ES is switched OFF. Plug your printer, fax machine, scanner, or other peripherals that do not need battery power into these outlets.

3Turn on the Unit

Press the ON/OFF switch to turn on the unit.

A single short beep and the green “Power On” indicator confirms the Back-UPS ES is on and ready to provide protection.

The Back-UPS ES should charge for at least 16 hours to ensure sufficient runtime. The unit is being charged whenever it is connected to utility power, whether the unit is turned ON or OFF.

If the red Building Wiring Fault indicator (located on the end near the power cord) is lit, your building wiring presents a shock hazard that should be corrected by a qualified

4electrician.

Transfer Voltage and Sensitivity Adjustment

(Optional)

In situations where the Back-UPS, or connected equipment, is too sensitive to the input voltage, it may be necessary to adjust the transfer voltage. To adjust the transfer voltage:

1.Plug the Back-UPS into the utility power source. The Back- will be in “Standby mode” (no indicators are lit).

2.Press the ON/OFF push button fully in for 10 seconds. The Online LED will begin glowing in a cyclical order: GREEN- AMBER-RED, indicating it is going into “Program mode”.

3.The Back-UPS will then indicate the current

sensitivity, as shown in the Transfer Voltage and Sensitivity Adjustment table below.

4.To select the LOW sensitivity setting, press the ON/OFF push button until the LED begins

flashing GREEN.

5.To select the MEDIUM sensitivity setting, press the ON/ OFF push button until the LED begins flashing RED.

6.To select the HIGH sensitivity setting, press the ON/OFF push button until the LED begins

flashing AMBER.

7.To exit Programming mode, once sensitivity is set, wait approximately 5 seconds, and all of the LED indicators will be off (unlit).

Place the Back-UPS ES to avoid:

- Direct sunlight - Excessive heat

- Excessive humidity or contact with fluids

Plug the Back-UPS ES power cord directly into a wall outlet; not into a surge protector or power strip.

Connect Modem / Phone / DSL / Fax

The Back-UPS protects a single line (2-wire) phone (including Digital Subscriber Line - DSL), Home Phoneline Networking Association (HPNA) type equipment, modem, or fax machines from surges when connected through the UPS as shown in the drawing below.
