1. Introduction
The information provided in this manual covers single phase 1000 – 3000 VA, uninterruptible power
systems, their basic functions, operating procedures, and emergency situations, also including
information on how to ship, store, handle and install the equipment. Only detailed requirements of
the UPS units are described herein, and installation must be carried out in accordance with this
manual. Electrical installations must also carefully follow local legislation and regulations. Only
qualified personnel should conduct these installations as failure to acknowledge electrical hazards
could prove to be fatal.
2. System description
Several different kinds of sensitive electrical equipment stay protected by a UPS (Uninterruptible
Power System) including computers, workstations, process control systems, telecommunications
systems, sales terminals, other critical instrumentation, etc. The purpose of the UPS is to protect
these systems from poor quality utility power, complete loss of power, or other associated problems.
Electrical interference abounds in many forms causing problems in AC power, from lightning,
power company accidents and radio transmissions to motors, air conditioners, and vending
machines, among others. So protection of sensitive electrical equipment is vital to protect against
power outages, low or high voltage, slow voltage fluctuations, frequency variations, differential and
common-mode noises, transients, etc.
In order to prevent power line problems reaching critical systems causing damage to software,
hardware and causing equipment to malfunction, the UPS helps by maintaining constant voltage,
isolating critical load output if needed, and cleaning the utility AC power.
2.1 General description
As a double conversion on-line UPS, it is able to supply uninterrupted, clean single-phase power to
your critical systems while keeping batteries charged continuously, regardless of whether utility

9
power fails or not.
In event that a power failure lasts longer than a UPS backup time, it will shut down avoiding battery
discharge, and as soon as voltage comes back, the UPS will automatically charge up and start
recharging the batteries.
As shown in fig.1 block diagram:
●An input filter reduces transients on the mains
●For maintaining 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.
Fig.1. Block diagram
Efficiency Optimizer function
The Efficiency Optimizer function is a new feature for the UPS adding cost effectiveness,
minimizing power loss and reducing power consumption. Alternating between bypass and on-line
modes is achieved automatically and in accordance with the conditions of the utility power. On-line
mode may be used during times of intermittent power supply, and bypass mode when power flows
smoothly in order to obtain greatest efficiency. Irregularities can be detected in less than a second,
and on-line mode reactivated immediately. Switching back to online mode occurs when input
voltage is outside ±10% or nominal (±15% selectable), when input frequency is outside of ±3Hz or
when no input line is available.

10
Although high efficiency is standard, the default operation is in on-line mode. Bypass can be
activated in the LCD panel, though on-line can be run permanently if preferred.
Free Run Mode
The UPS operates in free run mode when input frequency is outside of the selected input frequency
range. Free run mode is when output frequency does not match input frequency. When starting the
UPS, the frequency regulation detected is 50 or 60 Hz ±0.25Hz. Please refer to chapter 7.2 if you
want bypass available while running in free run mode.
Diagnostic tests
When you start the UPS, a diagnostic test is automatically executed that checks electronics, battery,
and reports any problems on the LCD display.
An advanced battery management system always monitors the conditions of the batteries sends any
forewarnings if replacement is needed. Otherwise every 30 days of normal mode operation, a battery
discharge test is performed and any problems reported on the LCD display.
Except during the first 24 hours after startup while the UPS is in charging mode (please see chapter
7.2), diagnostic tests can be performed manually from the front panel at any time.
2.2 System Configuration
The UPS device and the internal backup battery make up the system. Depending on the site and load
requirements of the installation, certain additional options are available as a tailored solution.
Planning a UPS system, the following should be taken into consideration:
●The total demand of the protected system shall dictate the output power rating (VA). Allow a
margin for future expansion or calculation inaccuracies from measuring power requirements.
●Backup time needed will indicate the battery size needed. If load is less than the UPS nominal
power rating then actual backup time is longer.
●The following options are available:
●External Battery Cabinets
●Transformer cabinets
●Maintenance bypass switches
●Connectivity options (relay card, SNMP/WEB card)

11
The following UPS models are available
Model Backup time
Internal batteries Recharge time to 90% capacity
UPS 1000VA 3~5 min 4 hours
UPS 2000VA 3~5 min 4 hours
UPS 3000VA 3~4 min 4 hours
Additional External Battery Cabinets are available if more back-up time is needed.
