Installation & Operation Manual
4. Operation Modes
Uninterruptible Power Supplies (UPS) most important function is the protection of critical and sensitive loads
from the irregular mains voltage conditions. They are used to supply uninterruptible energy to these loads
in such irregular mains voltage conditions and provide regulated energy supply to the equipment present in
the IT room, industrial workshop, hospitals and oces.
KEOR T EVO UPS during Online mode operation provides stable pure sine wave not aected by input voltage
uctuations. This helps to extend the life time of your sensible loads. Power factor of the current consumed
from mains is nearly one. This allows perfect adaptation to upstream generator or isolation transformer
supply. The reactive power consumption decreases.
During mains voltage failure, the energy needed for the load is provided by the internal battery (or installed
in external battery cabinet/s). These batteries are charged by an intelligent battery charging circuit when
mains voltage is within the limits. Batteries are lead acid battery (VRLA) and do not require any maintenance
until the end of their life time.
In case of long overload or inverter failure situation, UPS transfers the load supply to bypass line, and load is
supplied by mains . When the condition turns back to normal, UPS will continue to supply the load through
inverter.
UPS control and management is done by Digital Signal Processor (DSP) which is 200 times faster than
standard microprocessors. This helps to make your UPS smarter. DSP uses all the sources on optimum
conditions, observes the failure conditions, and communicates with your computer system.
UPS can be operated in one of the following operational modes depending on the condition of mains
voltage, battery, load, UPS status or user preference.
You may see the block diagram of UPS in Appendix-6 Description of UPS and Block Diagram.
4.1. Online Mode
Energy is drawn from the mains voltage input. Loads are supplied through the rectier and the inverter. The
AC voltage at the input is converted to a DC voltage by the rectier. The inverter converts this DC voltage to
an AC voltage with a stable sinusoidal waveform, amplitude and frequency. Output voltage and frequency
can be set via front panel. Output voltage is sinusoidal and has a regulated amplitude and frequency. It is
independent from the input voltage. The loads are not aected by the disturbances of the mains voltage.
If the mains voltage and frequency are in an acceptable range, Online Operation is possible.
Check Appendix-4 Technical Specications for Online Operation mode mains voltage limits.
The upper limit of mains voltage is independent from the load percentage and it is Ph-N: 270V. UPS switches
to Battery Operation mode when the mains voltage is over Ph-N: 270V. The mains voltage is required to
decrease below Ph-N: 260V for UPS to return Online Operation.
Online Operation Conditions;
• In case Online Operation is set as operation mode of UPS, the mains voltage is within the limits and/or if there
is no abnormal condition (overheat, overload, failure…etc.) UPS operates in Online Operation. Except for
failures, as soon as the abnormal conditions are eliminated, UPS switches to Online Operation automatically.
• In case Bypass Operation is set as operation mode of UPS and the voltage and frequency is out of the bypass
limits but within the rectier limits, UPS switches to Online Operation.
10
4.2. Battery Mode
In this operation, energy is drawn from the batteries. The loads are supplied via inverter. Output voltage is
sinusoidal and has a regulated amplitude and frequency.
Battery voltage should be in acceptable limits and the inverter should be enabled for the UPS to operate
in this mode.
UPS operates in Battery Operation in the following cases:
• While UPS is operating in Online Operation; if frequency/waveform/rms value of mains voltage go beyond
the rectier limits,
• While UPS is operating in Bypass Operation, if frequency/waveform/rms value of mains voltage go beyond
Bypass limits,
• If Inverter enabled: “YES”, Rectier enabled: “NO” are selected through the front panel (Authorisations
Menu for authorized Service Sta).
KEOR T EVO UPS operates with one or several parallel strings of 1 x 60pcs 12VDC battery with common
neutral.

Battery Management and Battery Back-Up Time
When UPS operates in Online or Bypass Operation; it continuously calculates and displays the remaining
back-up time.
Autonomy time depends on battery type, quantity, capacity, situation and load level. UPS stops supplying
the loads if the battery voltage decreases under a specic value.
Battery life depends on some parameters such as battery type, charge-discharge cycle, and depth of discharge, ambient temperature, conditions. Please check Technical Specications for the ideal environmental
conditions for the batteries. Using the batteries outside this temperature range will decrease battery operation time and battery life.
11
KEOR T EVO
Installation & Operation Manual
4.3. Bypass Mode
UPS transfers the loads automatically to the mains voltage in order to protect them during abnormal conditions.
While UPS operates in Online Operation, UPS switches to bypass automatically (in case the mains voltage
and frequency is within the limits of bypass) in the following conditions;
• During start-up
• Bypass Priority
• Inverter Fault
• Prolonged Overload, output short circuit
• High Heatsink Temperature
After these conditions are eliminated, the UPS automatically returns to inverter.
Bypass Operation Voltage Range
The mains voltage is required to be in certain range for Bypass Operation. Voltage tolerance is set 18% of
the output voltage in the factory. For instance; if the output voltage is Ph-Ph: 400V, the tolerance range of
bypass voltage would be Ph-Ph: 328V – 472V. In case the input voltage decreases below Ph-Ph: 328V or increases above Ph-Ph: 472V; if UPS runs in Bypass Mode UPS switches to Online Mode Operation; if UPS runs
in Online Mode Operation it cannot switch to Bypass Mode Operation even if a fault occurs. If the batteries
and the inverter are suitable to supply the loads, UPS switches to Battery Mode Operation.
Bypass Mode Operation voltage tolerance limit can be adjusted in certain ranges depends on the customer’s request on site by Legrand UPS Technical Service Personnel.
To return to Bypass Mode Operation; the mains voltage should turn back to +5V above of lower limit, -5V
down of upper limit of bypass limits. Default settings are Ph-Ph: 333V – 465V for Ph-Ph: 400V UPS.
Prolonged overloads in Bypass Operation may cause the thermal/magnetic protection act. In this case, all loads will be de energized.
12
4.4. Eco Mode
Eco Mode Operation can be chosen through the Commands Menu.
The purpose of using this mode is to increase the eciency up to 98% and to provide energy saving; since
the loads are supplied by the mains voltage directly, the loads are unprotected against any possible future
risks. (e.g. surge voltage, etc.). In devices with auxiliary mains supply; energy is drawn from the auxiliary
mains supply.
As long as the mains voltage and frequency within the limits, the load is supplied by the auxiliary voltage
in a controlled manner; double conversion chain is on standby while ensuring the recharge of the batteries.
Eco Mode Operation does not provide perfect stability in frequency/waveform/rms value
of the output voltage as in Online Operation. Thus, the use of this mode should be carefully
executed according to the level of protection required by the application.
This procedure may only be executed by trained Personnel.
During Maintenance Bypass operation; in case of any mains voltage interruption occurs,
all loads on the output will be deenergized. Maintenance Bypass Operation should not be
preferred for long time use.
4.7. Operation with External Maintenance Bypass (Optional)
The external manual maintenance bypass may be installed in the general distribution panel where
KEOR T EVO is installed, or in an external bypass panel that is supplied on request.
This operating mode enables the user to isolate the electronic circuitry of the UPS from the mains voltage
and the load without interrupting the load operation by connecting the loads directly to the bypass utility
supply. This feature is useful while performing maintenance or service and should only be executed by
trained Personnel.
Maintenance Bypass enables the user to isolate the electronic circuitry of the UPS from the mains voltage
and the load without interrupting the load operation by connecting the loads directly to the bypass utility
supply. This feature is useful while waiting service sta and should only be executed by trained Personnel.
UPS switches to another mode in case the mains voltage or frequency goes beyond the Bypass limits.
UPS returns to Eco Mode Operation when the auxiliary voltage returns to the limits.
Eco Mode Operation does not provide electronic short circuit current limitation. If a
short circuit occurs downstream distribution panel supplied by the UPS, the magnetic
protection o the Bypass line MCCB may act if not selective with downstream protection
and all loads will be de energized. Check discrimination applies between upstream and
downstream switchboard.
4.5. No Operation
This mode is used to make settings through Front Panel or by Service Software. To start-up UPS in No
Operation mode; all the circuit breakers must be at “0” position except Q1 Input circuit breaker and Q4
Bypass circuit breaker. In this mode UPS does not apply output voltage to supply the loads. After all settings
done during No Operation Mode, UPS should be restarted for the new service settings to be saved and
valid. It is not necessary to restart UPS for user settings to be valid.

Leakage Current Protection ***
Minimum 300 mA delayed (Type-B). When
used, the residual current earth leakage
protection system must be common for the
two AC inputs (common & auxiliary mains) and
installed upstream.

KEOR T EVO
Installation & Operation Manual
*Rectier protection alone should only be considered in the event of separate inputs; if the bypass and
rectier inputs are combined, the general input protection rating (bypass + rectier) must reect the
recommended bypass or general protection rating.
*Recommended discrimination of UPS downstream distribution with inverter short-circuits current (battery
mode).
**Cables must be selected 1.2 times larger than the recommended size for parallel topologies.
***Must be selective with residual current circuit breakers downstream of the UPS connected to the UPS
output. If the bypass network is separate from the rectier circuit, or in the event of parallel UPS, use a single
residual current circuit breaker upstream of the UPS.
If the loads generates high rate of third harmonic current ( THDI > 33% ), the
current on the common mains supply voltage and auxiliary mains supply voltage
input and output neutral conductors may have a value that is 1.5-2 times the
phase value during operation. In this case, size the neutral cables and the input/
output protection adequately.

6. Installation
When the UPS is delivered, examine the packaging and product carefully to see if any damage occured during transport.
If either possible or ascertained damage is found report it immediately to:
• The carrier;
• LEGRAND Technical Assistance Center.
Make sure that the unit received corresponds to the material specied on the delivery document. The UPS KEOR T EVO
packaging protects the equipment against mechanical and environmental damages. For greater protection it is also
wrapped in a transparent lm.
Check if the following are provided with the equipment:
• Battery fuses (three pieces)
Before the installation, please check if your UPS is customized following your special
requirements (if any).
