IMPORTANT SAFETY INSTRUCTIONS
This manual contains important safety instructions that must be followed to avoid fire, property damage, personal injury, or death. The warnings, precautions, and
instructions mentioned in this manual cannot cover all possible conditions and situations that may occur. The operator must understand that common sense and
caution are factors which cannot be built into this product, but must be supplied by the operator. Failure to heed these warnings may affect the warranty.
CAUTION! TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS:
 Plug the UPS into a 2-pole, 3-wire grounded receptacle (wall outlet). Make sure the wall branch outlet is protected by a fuse or circuit breaker and does not service
equipment with large electrical demands (e.g., air conditioner, refrigerator, copier, etc.). Do not use if the supply cord or plug is damaged. Always unplug the power
cord by the plug, never by tugging at the cable. Do not use with extension cords, an accessory surge protector, into its own output, or “daisy-chain” in serial fashion
with other power strips, UPS, surge protectors, or extension cords.
 Do not remove the cover except to service the battery. When replacing the battery, use the same number and type of battery. No user serviceable parts inside
except for battery. Servicing of user replaceable batteries should be performed or supervised by personnel knowledgeable about batteries and required precautions.
Do not attempt to add external batteries to the UPS.
 Although the UPS may be unplugged from the utility power, hazardous voltage may still be present through the battery. Always turn off the unit and unplug it from
the AC power source before servicing the battery.
 Place the UPS at least 20 cm (7.8 in.) away from other objects to give it adequate airflow around the unit. Do not cover the UPS' cooling vents and avoid exposing
the unit to direct sunlight or installing the unit near heat emitting appliances such as space heaters or furnaces. Do not allow the UPS to be exposed to moisture,
rain excessive heat, or direct sunlight. Do not allow liquids or any foreign object to enter the UPS. Do not place beverages or any other liquid-containing vessels (i.e.,
aquariums) on or near the unit. Condensation from liquids can cause the unit to short circuit.
 Install in a temperature and humidity controlled indoor area free of conductive contaminants. Keep on a flat stable surface. If wall mounting, install in a vertical
position to the side of a wall, desk, table, or other stable surface to avoid overheating.
 In the event of an emergency, press the OFF button and disconnect the power cord from the AC power.
 Do not dispose of batteries in a fire, the battery may explode. Do not open or mutilate batteries. Released material is harmful to the skin and eyes and may be toxic.
 Do not attach non-computer-related items, such as medical, life-support, or nuclear equipment, microwave ovens, or vacuum cleaners to UPS. Do not use in any
circumstance that would affect operation or safety of any life support equipment or with any medical applications or patient care.
 Always adhere to all local and national electrical codes.
 Risk of suffocation, choking, or electric shock. Do not allow people with reduced sensory, physical, or mental capacity, children, or pets play with the plastic bag,
packaging material, or battery that was included with your unit.
 Do not use the UPS on any transportation such as airplanes or ships. Shocks or vibrations caused during transit and the damp environment can cause the unit to
short out.
 Do not use the UPS other than its intended use.
 Use tools with insulated handles and wear rubber gloves and boats when servicing. Do not handle any metallic connector before power has been disconnected
when servicing. Always remove metallic objects such as wristwatches and jewelry such as rings when replacing the battery.
 Recycle used batteries in accordance with local ordinances or regulations. Do not dispose battery with regular household waste; batteries are considered hazardous
waste. Remove the battery from the UPS before disposal. Check your local recycling center or waste disposal center to locate your nearest recycling location.
INSTALLING YOUR UPS SYSTEM
OVERVIEW
Thank you for purchasing the Micro UPS Series from Maruson. The Micro UPS provides battery backup during power outages, surge protection, and protection from
power sags. The built-in automatic voltage regulation (AVR) function adjusts minor voltage fluctuations instead of switching over to battery mode for the battery
backed outlets. In the event of a power outage, the UPS will provide temporary power to connected equipment plugged into the Battery-Backed Outlets.
UNPACKING
Inspect the package contents upon receipt. Notify your local dealer if there is any damage. The box should contain the following: (1) UPS and (1) User. Select
models will include (1) Power Cord and/or (1) USB Communication Cable. Power management software for select models can be downloaded online at
www.MarusonUSA.com.
USE GUIDE
 Make sure that the total Volt-Amp (VA) requirements of your computer, monitor, and peripheral equipment does not exceed the rated capacity. There are many
factors that can affect the amount of power that your computer system will require. For optimal system performance keep the connected load below 80% of the
UPS’s rated capacity.
 Ensure that the equipment plugged into the battery power-supplied outlets does not exceed the UPS unit's rated capacity. If rated unit capacities are exceeded, an
overload condition may occur and cause the UPS unit to shut down and/or the circuit breaker to trip.
 Your new UPS may be used immediately upon receipt. However, recharging the battery for at least eight (8) hours when first receiving the new unit is recommended
to ensure that the battery's maximum charge capacity is achieved. Charge loss may have occurred during shipping and storage. To recharge the battery, simply
leave the unit plugged into an AC outlet. Your UPS is equipped with an auto-charge feature. When the UPS is plugged into an AC outlet, the battery will
automatically recharge.
 With the UPS unit off and unplugged, connect the computer, monitor, and any equipment into the battery power supplied outlets. Never plug a laser printer,
copier, space heater, vacuum, paper shredder or other large electrical device into the battery power supplied outlets. The power demands of these devices
will overload and possibly damage the unit or connected device, which will not be covered under warranty.
 To maintain optimal battery charge, leave the UPS plugged into an AC outlet at all times. To store your UPS for an extended period, fully charge the battery before
storing. Recharge the battery every three months to ensure battery life.
 Battery life and runtime will vary based on battery age, maintenance, altitude, ambient temperatures, power quality of AC power, and frequency of shorts to the UPS.
