temperatures such as blankets, pillows and sleeping bags.

WARNING: Electric shock hazard Do not remove cover. No user serviceable parts inside. Refer servicing to qualified service

personnel.

WARNING: Shock and burn hazard A battery can present a risk of electrical shock or burn from high short-circuit current.

CAUTION: Risk of damage to the Backup Power System The unit will not work when connected to any AC load that has its neutral conductor connected

to ground. Such loads include AC distribution wiring and house wiring.

CAUTION: Equipment Damage Do not expose the Backup Power System, to temperatures over 104°F (40°C).

PRECAUTIONS FOR USING RECHARGEABLE PRODUCTS

WARNING: Explosion and Fire Hazard

· Follow all instructions published by the battery manufacturer and the manufacturer of the

equipment in which the battery is installed.

· Make sure the area around the battery is well ventilated.

· Never smoke or allow a spark or flame within the vicinity of the engine or batteries.

· Be careful not to drop a metal object on the battery. Do not allow a metal tool to

simultaneously touch the positive and negative cable ends or battery terminals. It can

create an explosion hazard.

5

· Remove personal metal items such as rings, bracelets, necklaces and watches when

working with batteries. Batteries produce a short-circuit current high enough to weld a ring

or other similar objects to metal, causing a severe burn.

· If you need to remove a battery, always remove the positive terminal from the battery first.

Make sure all accessories are off to avoid risk of hazard.

· Use safety goggles or safety glasses with side shields which comply with current national

standards, or when needed, a face shield. Use as dust mask in dusty work conditions. This

applies to all persons in the work area.

· Make sure there is someone nearby in case of an emergency.

· Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing and

eyes.

· Wear complete eye and clothing protection. Avoid touching your eyes while working near

batteries.

· If battery acid contacts skin or clothing, wash immediately with soap and water. If acid

enters your eyes, immediately flood them with cold running water for at least twenty

minutes and seek medical attention immediately.

· Keep a supply of baking soda on hand when working with the batteries. Baking soda

neutralizes lead-acid battery electrolytes.

Caution: Equipment damage

When unit is supplying backup power from its batteries, its output is a non-sinusoidal modified

sine wave, which is different from pure sine wave utility-supplied electricity. Certain types of

load equipment which require true sine wave power may be damaged.

Most rechargeable battery-operated equipment uses a separate charger or transformer that is

plugged into an AC receptacle and produces a low voltage charging output. However, some

chargers for rechargeable batteries can be damaged if connected to the Backup Power

System.

DO NOT use the following with the Backup Power System:

· Small battery-operated products such as flashlights, electric razors, and night lights that

can be plugged directly into an AC receptacle to recharge.

· Some chargers for battery packs used in power tools. These chargers display a warning

label stating that dangerous voltages are present at the battery terminals.

NOTE: If you are uncertain of compatibility with Backup Power System, contact the equipment

manufacturer to determine the rechargeable product’s compatibility with the modified sine wave

(non-sinusoidal) AC wave form.

Attention: Charge unit before use Charge the Backup Power System immediately after purchase. Recharge after each use and at

least once every 90 days.

CAUTION

· Do not plug surge-protected power bars into the unit’s 120V AC outlets

· Do not connect an AC power source to the 120V AC outlets.

· Do not connect the unit’s AC power cord to its 120V AC outlets.

To install the Backup Power System: 1. Plug the power cord directly into a wall outlet (not into a surge protector, power strip, or

power bar).

2. Connect your AC-powered devices or small household appliances to one or more of the five

AC outlets of the Backup Power System.

3. Turn on the unit by pressing the power button for half a second. The green AC power LED

confirms that the backup power system is ON and ready to provide backup power. When

the battery needs recharging, the LED screen flashes “CHg” two times, then the battery

capacity (%) once. This pattern of flashing continues until the battery capacity reaches

100% and “FUL” appears on the screen.

Important When installing the UBPS, ensure that there is a minimum of 3” (7.5 cm) of space

around the unit for optimal ventilation.

Backup power features The unit’s 120V AC outlets are permanently backed up by the internal battery. To activate the

AC outlets, turn on the unit using the power button. During a power outage or other utility

problem (such as brownouts and over-voltages), the Backup Power System will keep your

AC-powered products, office equipment, or small household appliances powered, depending

on the power draw of your application. When utility power is restored, the unit automatically

recharges its internal battery.

Important: When connected to utility power, the unit automatically provides AC power from its

internal battery when the utility voltage falls outside the 108-127V AC range. The emergency

LED light turns on automatically to illuminate the rear AC outlets.
