Introducon
The informaon provided in this manual covers single phase 700VA, 1000VA, 1500VA, 2000VA, and 3000VA un-
interrupble power systems, their basic funcons, operang procedures, opons available and emergency situa-
ons. It also includes informaon on how to ship, store, handle, and install the equipment. Only detailed require-
ments of the UPS units are described herein, and installaon must be carried out in accordance with this manual.
Electrical installaon must also carefully follow local legislaon and regulaons. Only qualied personnel should
conduct these installaons as failure to acknowledge electrical hazards could prove to be fatal.
Product Descripon
Many dierent kinds of sensive electrical equipment can be protected by an Uninterrupble Power Supply (UPS)
including computers, workstaons, process control systems, telecommunicaons systems, sales terminals, other
crical instrumentaon, etc. The purpose of the UPS is to protect these systems from poor quality ulity power,
complete loss of power, or other associated problems.
Electrical interference exists in many forms, causing problems in AC power, from lightning, power company ac-
cidents and radio transmission motors, air condioners, and vending machines. Protecon of sensive electrical
equipment is vital to protect against power outages, low or high voltage condions, slow voltage uctuaons,
frequency variaons, dierenal and common-mode noise, transients, etc.
To prevent power line problems from reaching crical systems causing damage to soware, hardware, and equip-
ment malfuncons, the UPS maintains constant voltage, isolang crical load output and cleaning the ulity AC
power.
Double Conversion Online Technology
A double conversion on-line technology UPS provides completely isolated, clean, uninterrupted single- phase
power to your crical systems, while maintaining the baeries for their maximum potenal. In the event that the
power failure lasts longer than the UPS backup me, the UPS will shut down avoiding baery damage. When the
input AC voltage returns, the UPS will automacally return online to recharge the baeries.
As shown in block diagram:
• An input lter reduces transients on the incoming ulity.
• To maintain full baery charge, the AC input power is reced and regulated in the recer feeding power
to the baery converter and inverter.
• DC power is converted to AC in the inverter, passing it on to the load.
• Power is maintained from the baery during a power failure.
• The converter increases voltage appropriately for the inverter.

Diagnosc Tests
When the UPS is started, a diagnosc test is automacally executed, checking the electronics and baeries, report-
ing any problems on the LCD display.
System Conguraon
The UPS device and the internal baeries make up the system. Depending on the site and load require-
ments of the installaon, certain addional opons are available for the soluon.
Planning a UPS system, the following should be taken into consideraon:
• The total demand of the protected system shall dictate the output power rang (VA). Allow a margin for
future expansion or calculaon inaccuracies from measured power requirements.
• Backup me required will indicate the baery size needed. If the load is less than the UPS nominal power
rang, then actual backup me is longer.
• The following opons are available:
o Connecvity Opons – Web/SNMP Card, Relay Card, Modbus Card
o Baery packs, bypass switches
See the Specicaon secon of this manual for addional model informaon.
Please comply with all warnings and operang instrucons in this manual strictly. Save this manual prop-
erly and read carefully the following instrucons before installing the unit. Do not operate this unit be-
fore reading through all safety informaon and operang instrucons carefully.
Transportaon
• Please transport the UPS system only in the original package to protect against shock and
impact.
Preparaon
• Condensaon may occur if the UPS system is moved directly from cold to warm environment.
The UPS system must be absolutely dry before being installed. Please allow at least two
hours for the UPS system to acclimate the environment.
