1. Introduction
2. System Description
The information provided in this manual refers to our single phase, 700VA through 3000VA,
true on-line uninterruptible power supplies. It covers basic functions, operating and installation
instructions, cautionary notes and detail on how to ship, store and handle them. Installation must
be carried out in accordance with this manual as well as local electrical regulations and should
only be performed by qualied personnel to avoid the risk of electric shock or damage to the unit.
Any warranties covering these units will become void if the unit is found to have been incorrectly
connected or tampered with.
2.1 General description
Congured as a true, on-line double conversion unit, this UPS is able to supply seamless, pure
single-phase AC power to critical loads while keeping the batteries charged continuously. In
the event that a power interruption lasts longer than the UPS’s backup time capability, it will
shut down to avoid complete battery discharge. As soon as AC power is restored, the UPS will
automatically restart and begin recharging the batteries.
A block diagram of the UPS infrastructure is shown in Fig. 1:
• An input lter reduces transients, noise and surges on the incoming AC supply
• AC power is rectied and regulated by the rectier supplying power to the inverter and battery
converter. Battery voltage and charge is maintained at optimum levels.
• DC power is converted to AC power by the inverter which passes it on to the load.
• Power is supplied from the battery during a power failure or deep voltage sag.
• The converter increases voltage to an appropriate level for the inverter.
• An integral automatic bypass switch seamlessly circumvents the electronics in the event of a
component failure ensuring continuous power to the load.

Efciency Optimizer
The Efciency Optimizer is a unique feature that reduces long-term cost of ownership by minimizing
power loss and reducing power consumption thereby making the entire system extremely efcient.
Simply put, the UPS automatically alternates between bypass and on-line modes depending upon
the condition of the incoming AC power. The UPS will remain in on-line mode during any type
of power disturbance but unlike traditional on-line systems, will switch to bypass mode when AC
power is within acceptable limits in order to achieve greatest efciency. Power disturbances can
be detected in less than a second, and on-line mode reactivated immediately. Switching back
to online mode occurs when the input voltage is outside of ±10% of nominal (±15% selectable),
when input frequency is outside of ±3Hz or when no AC power is present.
While the default operation is on-line mode, bypass can be activated via the LCD panel. The
Efciency Optimizer can be de-activated and the unit can be run permanently in on-line mode if
preferred.
Free Run Mode
Free run mode is dened as being when the output frequency is xed and not synchronized with
the input frequency. When activated, the output frequency regulation is automatically set to either
50 or 60 Hz and is regulated to within within ±0.25Hz. Please refer to Chapter 7 for instructions on
how to activate bypass mode while the UPS is in free run mode.
Diagnostic tests
Whenever the UPS is turned on, a diagnostic test to check the status of the internal electronics and
battery is activated. Any errors or faults are displayed on the LCD panel.
An advanced battery management system continuously monitors the condition of the batteries and
notifies the user in advance if replacement is needed.
In addition, a battery discharge test is performed every 30 days in normal mode operation, and any
problems are displayed on the LCD panel.
Diagnostic tests can be performed manually from the LCD panel at any time, except during the first
24 hours after startup while the UPS is in charging mode (see Chapter 7).
