1. Introduction
The information provided in this manual is applicable to single phase 500-2100watt uninterruptible power
systems, their basic functions, operating procedures, and emergency procedures. It also includes
information on how to ship, store, handle and install the equipment. This manual also provides detailed
requirements for the safe installation and use of the UPS. Installation must be carried out in accordance
with this manual. Electrical installations must also carefully follow local code and regulations. Only
qualified personnel should install or maintain this equipment as failure to follow safety procedures or
recognize electrical hazards could result in damage to the equipment and property, injury or even death:
Importa nt Notice :
Read the following before proceeding:
a. Read instructions carefully before operating the UPS.
b. UPS power connect instruction should be followed.
c. ELECTROCUITION DANGER! Do not open the case.
d. If the UPS will be stored for a long period, the battery must be charged once every 90 days.
e. Maintain the load within the rating of UPS to prevent faults.
f. Handle unusual events according to the trouble-shooting guide.
g. Keep the UPS clean and dry.
2. System description
Your new UPS (Uninterruptible Power System) will protect your electronic and electrical equipment such
as computers, workstations, process control systems, telecommunications systems, sales terminals and
other critical instrumentation from unstable or otherwise poor quality utility power, power failure, and other
adverse events..
Electrical interference abounds in many forms and can cause unreliable operation of your critical
equipment. Sources of interference include, but are not limited to, utility company generated fluctuations
and noise from such diverse sources as lightning equipment, radio frequency interference from worn or
damaged motor brushes, air conditioners, vending machines, appliances and even arcing across
insulators on utility poles. Additionally, power failures, low or high voltage, voltage surges and
fluctuations, frequency variations, differential and common-mode noises and transients. All must be
addressed to ensure continual and reliable operation of your vital equipment
Your new UPS will help prevent those issues from affecting your systems and causing damage or
malfunction of your critical equipment including computer hardware and sensitive software by maintaining
a consistently clean power source, isolating critical load output if needed, and filtering noise from your
facilities AC power while providing an uninterrupted stream of backup power in the event of a utility power
failure.
2.1 General description
Your new double conversion on-line UPS is able to supply uninterrupted, clean, single-phase power to
your critical systems while keeping batteries continuously charged and provide a back up in the even of
a utility power failure.
If a power failure lasts longer than the rated UPS backup time, your UPS will shut down systematically,
avoiding battery discharge. As soon as utility power is restored, the UPS will automatically switch to
utility power and start recharging the batteries.
As shown in the block diagram, Figure 1:

An input filter reduces transients on the mains
 To maintain full battery charge, AC-power is rectified and regulated in the rectifier feeding power to
the inverter and battery converter.
 DC power is converted to AC in the inverter passing it on to the load.
 Power is maintained from the battery during a power failure.
 The converter increases voltage appropriately for the inverter.
