Introduction
Thank you for choosing our high technology E1 series uninterruptible power supply.
Product you purchased was manufactured as per ISO9001 quality assurance system
using most advanced technology.
In order to get highest efficiency from your product and to ensure a safe use, we
recommend that you strictly read and retain this user’s manual for later reference. In
addition, do not hesitate to contact your nearest authorized vendor or technical support
center for more detailed information and/or assistance.

1 Overview
E1 Series Uninterruptible Power Supply (UPS) is a high technology product that
was manufactured to provide uninterruptible energy to fields including but not limited to
industrial facilities, hospital, schools, banks, business centers, and computer and
communication systems. You can use your device, which is equipped with static bypass
system, all necessary protection systems and an online structure with all loads safely.
Because this device was designed double conversion online system basis, it
supplies all connected loads with continuous voltage with stable frequency and stable
amplitude. Therefore, no transition period is necessary when electric power is
interrupted or recovered.
With deployment of a DSP (Digital Signal Processor) based microprocessor in
its design, UPS output voltage is accurately controlled, thereby ensuring stable
operation of devices that are sensitive to voltage fluctuations.
Static bypass unit of the system ensures that the mains voltage is constantly
kept at backup. In case of an overload, this system takes over the load uninterruptedly.
Once overload is recovered, load is transferred back to inverter. In addition, static
bypass unit acts in similar way in cases of UPS failure and prevents power shortage at
the system.
UPS will supply loads from the battery in cases of mains voltage outage. Loads
are supplied from the battery for a backup time that varies depending on the capacity of
batteries used. If mains voltage is recovered during the backup time, UPS will return to
online mode automatically and continue supplying power to loads. Meanwhile, batteries
are charged as well.
When UPS is connected to a computer system using any of a several
communication options, all functions of the device can be monitored by means of
designated software. Connecting to a remote device via modern is possible to transfer
information on device related functions and problems.
System used in E1 series uninterruptible power supply is shown in the following
simple block diagram.

4 Operation Modes
4.1 Online Operation Modes
4.1.1 Normal Mode
E1 Series UPS devices supply all connected loads with continuous voltage with
stable frequency and stable amplitude during online operation. Rectifier and inverter
units run continuously. Load is supplied with a stable sinusoidal voltage generated by
the inverter. Inverter and bypass voltages are synchronized. So, uninterruptable load
transfer can be done in the UPS. Batteries are constantly kept at a buffer charge
voltage. Mimic diagram displayed on the LCD screen is as shown in figure-6 below.
During this operation mode, LED bar is constantly lit in green.
Figure–6 Normal mode
UPS will switch back from this operation mode when any of the following occurs:
 Mains voltage or mains frequency is out of limits
 Overheat or overload
 Battery test procedure
 A failure
4.1.2 Battery Mode
Rectifier unit does not run, inverter unit runs. Inverter unit is supplied from the
battery. Load is supplied a stable sinusoidal voltage generated by the inverter. Batteries
are in discharge position. Mimic diagram is as shown in the figure7. In this operation
mode, LED bar flashes green.
Figure–7 Battery Mode
When any of the following occurs, UPS will switch to this operation mode.
 Mains voltage or mains frequency is out of limits
 Mains phase sequence fault
 Battery test procedure

E1 SERIES USER MANUAL
E1 Series 10-20kVA Rev 1.0.1 Page| 15
4.1.3 Bypass Mode
Inverter and rectifier units do not run. Load is supplied by bypass source over
static bypass unit. Mimic diagram is as shown in the figure-8. In this operation mode,
LED bar is constantly lit in red.
Figure–8 Bypass mode
When any of the following occurs, UPS will switch to this operation mode.
 As soon as UPS is turned on
 Cases of overheat shutdown, overload shutdown or over current inverter
 Stopping the UPS by remote bypass switch
 Any failures in rectifier or inverter stages
4.2 Economic Operation Mode (ECO-MOD)
Load is fed from bypass source instead of energy is produced by the UPS in
this mode. Rectifier and inverter units run in this mode. The Voltage, frequency and
waveform of bypass source are continuously monitored. Inverter voltage is kept ready as
synchronous with bypass source. Mimic diagram is as shown in the figure-9. In this
operation mode, LED bar is constantly lit in red.
Load is transferred to the inverter unit automatically when voltage or frequency
of bypass source is out of limit. Load is transferred to the bypass automatically when
voltage or frequency of bypass source returns to normal limits.
Figure- 9 Economic operation mode
Batteries are kept in charge in this mode. Rectifier unit is stopped, inverter unit
start to feed from batteries and batteries start to discharge when mains voltage is out of
limit. If mains voltages return to normal limits, rectifier will step in and batteries start to
charge.
4.3 System Off Mode
Rectifier, inverter and static bypass units do not run. In this operation mode, LED
bar will be fully off. Mimic diagram is as shown in the figure-10.

E1 SERIES USER MANUAL
E1 Series 10-20kVA Rev 1.0.1 Page| 16
Figure- 10 System off mode
UPS will switch to this operation mode if any of the following occurs.
 Stopping the UPS by ‘EPO’ switch
 Stopping the UPS through a computer (shutdown).
 Bypass voltage and frequency is out of limits during bypass operation mode
 Static bypass switch (SCR) malfunction during bypass operation mode
 Shutdown due to overheat or overload during stop mode
4.4 Manual Bypass Mode
Load is fed from mains in this mode. Load will be transferred to mains without any
problem when steps in operating procedure are carried out. The UPS can be turned off
due to load feed from mains. This operation mode is used for maintenance.
Maintenance and repair of the UPS can be done by authorized personnel without cut the
power.
