1. Introduction
The information provided in this manual covers single phase 6000 – 10000 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 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. 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)
The following UPS models are available
Backup time with internal batteries Recharge time to 90% capacity
UPS 6000VA
4 hours
UPS 10000VA
4 hours
Note the battery backup times are approximate and could vary depending on battery life and
temperature configuration.
Additional External Battery Cabinets are available if more back-up time is needed.
3. Safety information
Information presented here is vital to all personnel and please also read the UPS safety manual.
Storage and Transportation
Please handle with extreme caution since a high amount of energy is contained with the batteries.
Always keep the unit in position as marked on the packaging and never drop the unit.
If flammable substances such as gases or fumes are present or if the room is airtight, a safety
hazard situation exists, in which no electrical equipment should be operated.
The instructions in this manual explain how to install the UPS safely. Not acknowledging such
electrical hazards may be fatal, so keep this manual for all future reference.
It is strongly advisable not to open the UPS cabinet as the components have very high
voltage and touching them may be fatal. Only a technician from the manufacturer or an
authorized agent may service the unit. This UPS unit’s output receptacles carry live
voltage even when not connected to a power supply as it has its own energy source.
User’s operations - The only operations that users are permitted to do are:
Turning the UPS unit on and off
Operating the users interface
Connecting data interface cables
All such operations are to be performed exactly as instructed in this manual. The greatest care
possible must be taken for any of these operations and any change thereof may prove very
hazardous to the operator.
4. Storage

6. Computer and alarm connections
At the back of the UPS is an interface allowing direct communication with your computer
system, the location of which can be found in figure 4. There is a RS232 serial data interface,
one USB data interface and an emergency power off switch supplied. However, the RS232 port
cannot be used when the USB interface is in use, as USB port has the absolute priority than
RS232. In addition there is an optional interface slot that allows you to install different
communications cards. It can be used parallel with either the RS232 or USB ports. Currently
there are two cards available for the optional interface slot. An SNMP/WEB card allows
management and monitoring over a network or internet, and the AS/400 card allows voltage free
relay contacts. Your local dealer will have more information about these option cards.
Connecting the UPS to a Computer
The communication device for the UPS and PC comes as a complete package with power
management software. Only the communication cable provided with UPS may be used to
connect to your computer, which is accomplished through the UPS RS232 port. Also ensure that
the operating system on your computer is supported. Instructions provided in the power
management software will help with this installation. Other advanced power protection solutions
such as SNMP are provided by your dealer.
RS-232 Standard Interface port
The RS-232 interface uses a 9-pin female D-sub connector, consisting data about utility, load
and the UPS. The interface port pins and their functions are identified in the following table.
Fig. 4
USB port (option)
Connecting the UPS to your computer is accomplished through the USB port on the back of
your computer. USB compliant hardware and operating system will be necessary including
installation of a UPS driver. The serial port cannot be used when using the USB port. The USB
cable is standard and can be bought separately.
6.1 EPO port (emergency power off)
A customer-supplied switch located remotely can be used to open the EPO connection and
allows UPS output receptacles to be switched off. Since the EPO shuts down the equipment
immediately, orderly shutdown procedures are not followed and not by any power management
software. The UPS will have to be manually restarted in order to regain power to the outlets.

8. Maintenance
With a minimal amount of maintenance, you can expect the UPS to application, otherwise
consider changing the batteries. have a long life free of trouble. The most critical issues for the
reliability of the UPS are environmental issues. Ensure that the temperature and humidity are
always according to specifications and keep the area around the unit clean and dust free.
At a temperature of 25°C, the typical battery lifetime is 4 years.
Pay special attention on UPS air apertures and make sure the apertures and holes are not blocked
or covered by dust.
Also check at regular intervals of 6 to 12 months whether the back-up time of the battery is
adequate for its
Batteries may cause electrical shock or burn from high short circuit currents. Please
observe the following precautions: 1. Remove jewelry and metal objects such as
watches and rings. 2. Use tools that have insulated handles. 3. Keep tools and other
metal objects from contacting and away from the batteries.
ELECTRIC ENERGY HAZARD. Do not attempt to rewire, alter, or change any
battery wiring or connectors. Attempting to make such alterations can cause injury.
Replace the batteries with the same number and type as originally installed batteries.
DO NOT DISCONNECT the batteries while UPS is in Battery mode.
