Input magnetic protection devices shall have D characteristic.

*Load leakage currents are added to those generated by the UPS. If loads with high leakage currents are
present, adjust this value accordingly. It is recommended to adjust the protective device after measuring
the total leakage current with the UPS installed and operational with the intended load.

During transitory phases (power failure, return and voltage fluctuations) short leakage current peaks may
occur. Make sure that the protection is not activated in such cases.

If the loads have a nonlinear characteristic, the current on the mains input, separate by-pass
mains 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 accordingly.

Separated by-pass mains input connection (optional)

Bring the circuit breaker on the distribution panel to “OFF” or “0” position before making the
connections

Connect the phases to bypass (X3) L1, L2 and L3 terminals.

Make sure that the phases have the same sequence with the input supply.

Connect neutral to N terminal of X3.

2.1.1.1

External Battery Connection

Do not put the battery fuses into the fuse holder (F5) before operating the equipment and seeing
the “NORMAL” message on the LCD.

Devices with internal batteries may have dangerous voltages on the battery terminals

To connect external batteries, do the following:

 Switch the circuit breaker of the external batteries to “OFF” or “0” position.

 Connect the (-) pole of the external batteries to the battery (-) terminal,

 Connect the (+) pole of the external batteries to the battery (+) terminal,

 Connect the midpoint of the external batteries to the battery N terminal.

Danger of explosion and fire if batteries of the wrong type are used.

2.1.1.1

Output Connection

To enable the short circuit protection feature of the UPS, each load shall be fed over a separate

circuit breaker chosen according to the load current. This may provide quick disconnection of the
short circuited load and operation continuity of the other loads. To obtain maximum protection,
the rating of each individual load circuit breaker shall have the minimum value, which is enough

to carry the full load current continuously.

Rated apparent and active power of the loads shall be less than the UPS power ratings.

Connect the loads to output (X4) Line and N terminals.

2.1.1 Communication Interface Connections

Related information is given in “communication” section.

12

3 Modes of Operation

There are three operation modes, which differ in the path of the energy flow.

UPS block diagrams and the energy flow path in each operation mode is shown below:

When UPS has no separate bypass mains input, bypass line is also fed from the mains input. Thus, if such
a device is in question, mains input shall be comprehended when the bypass mains input is referred in the
following sections of the manual.

UPS behavior at the start-up is different from the usual operation. The UPS can only operate in bypass
mode during start-up. So, in order for the UPS to start-up, frequency/waveform/rms value of the bypass
mains voltage shall be in acceptable limits and bypass shall be enabled.

13

After start-up, the following applies:

Operation mode depends on the priority, inverter, rectifier and bypass preferences made by the user and
mains, separate by-pass mains and battery voltages.

Priority and inverter, rectifier and bypass preferences can be set by using the COMMANDS and extra
commands (EXTCMNDS) menus.

If operation in any of these modes is impossible, output voltage will not be present. In this case, loads will
not be fed, and “VSECFLR” message is shown on the LCD instead of operation mode.

3.1 Bypass Mode

Devices without separate bypass mains input, energy is drawn from the mains. In devices with separate
bypass mains input, energy is drawn from the separate bypass mains.

Loads are fed via static bypass line.

Output voltage has the same amplitude, frequency and waveform as the input voltage.

Current drawn by the loads are only limited by the thermal/magnetic switches over the energy flow path.

Voltage, frequency and waveform of the bypass supply shall be within their tolerance limits, and bypass
shall be enabled for the UPS to operate in this mode.

When the upper provisions are met, the UPS works in bypass mode in the following conditions:

 During the start-up

 If the bypass priority is selected

 If the inverter is disabled or blocked

 In case of a prolonged overload

ECO Mode

You can save energy by selecting the bypass priority. Efficiency in bypass mode is higher than the
efficiency in normal mode. If the bypass priority is selected, the UPS will operate in bypass mode
whenever the frequency/waveform/rms value of bypass mains voltage is within their tolerance limits. If
the bypass voltage goes beyond these limits, the UPS switches into normal operation.

Bypass mode does not provide perfect stability in frequency/waveform/rms value of the output
voltage like in normal mode. Thus, the use of this mode should be carefully executed according to
the level of protection required by the application.

Bypass mode does not provide electronic short circuit protection like in normal mode. If a short
circuit occurs on the output during bypass operation, the thermal/magnetic protection will act

and all loads will be de energized – load will be stopped.

Prolonged overloads may cause the thermal/magnetic protection to act. In this case, all loads will
be de energized – load output will be stopped.

14

3.1Normal Mode

Energy is drawn from the mains input.

Loads are fed via the rectifier and the inverter. The AC voltage at the input is converted to a DC voltage
by the rectifier. The inverter converts this DC voltage to an AC voltage with a stable sinusoidal waveform,
amplitude and frequency.

Output voltage is sinusoidal and has a regulated amplitude and frequency. It is independent from the input
voltage.

The inverter is synchronized in frequency with the bypass mains input to enable load transfer to the
bypass supply without any interruption, in case of an overload or inverter failure.

Voltage and frequency of the mains input shall be within their tolerance limits, and both the rectifier and
the inverter shall be enabled for the UPS to operate in this mode.

When the upper provisions are met, the UPS works in normal mode in the following conditions:

 If the inverter priority is selected.

 If the bypass priority is selected but bypass is disabled or frequency/waveform/rms value of

bypass mains voltage is not within acceptable limits.

3.1 Battery Mode

Energy is drawn from the batteries. Loads are fed via the inverter.

Output voltage is sinusoidal and has a regulated amplitude and frequency. It is independent from the
battery voltage.

Battery voltage shall be within acceptable limits and the inverter shall be enabled for the UPS to operate in
this mode.

When the upper provisions are met, the UPS works in battery mode in the following conditions:

 If rectifier is disabled.

 If the rectifier is disabled or frequency/waveform/rms value of mains voltage is not in acceptable

limits.

5 Operating Procedures

This chapter defines the operating procedures to be followed to activate, deactivate and manage the UPS.
The instructions shall be applied in the sequence in which they are written only – do not alter or miss a
step – to do so may cause a fault or failure.

5.1 Commissioning

Make the connections according to the installation section.

Switch the circuit breaker on the input distribution panel “ON” / “I”.

Switch the circuit breaker on the by-pass distribution panel “ON” /”I”.

If the by-pass mains input is separate, bring the by-pass circuit breaker (F4) to “ON”/ “I” position.

Bring the input circuit breaker (F6) and inrush circuit breaker (F1) to “ON”/ “I” position.

Bring the output circuit breaker ( F2 ) to “ON” / “I” Position.

Wait for the LCD to start up. Set the date and time.

Wait to see the “NORMAL” message on the LCD.

Bring the circuit breaker of the external battery cabinets to “ON”/ “I” position.

Bring the battery circuit breaker (F5) to “ON”/”I” position.

The UPS starts up in bypass mode and automatically switches to normal mode. “NORMAL”
message will not be displayed, until the UPS switches to normal mode.
Frequency/waveform/rms value of the bypass mains voltage shall be within acceptable limits and

bypass shall be enabled for the UPS to start-up. Voltage and frequency of the mains input shall be

within their tolerance limits, and both the rectifier and the inverter shall be enabled for the UPS

to operate in normal mode.

5.2 Decommissioning

Bring the output circuit breaker (F2) to “OFF”/”0” position.

Bring the input, inrush and manual by-pass circuit breakers (F1, F6 and F3) to “OFF”/”0” position.

If the by-pass mains input is separated, bring the by-pass circuit breaker (F4) to “OFF”/”0” position.

Bring the battery circuit breaker (F5) to “OFF”/”0” position.

Bring the circuit breaker of the external battery cabinets to “OFF”/”0” position.

Switch the circuit breaker on the input distribution panel “OFF” / “0”.

Switch the circuit breaker on the by-pass distribution panel “OFF” / “0”.

In the event of an extended period of UPS inactivity, the batteries must be charged periodically
in order to prolong battery life. The charge period, which depends on the temperature, is given
in the “storage” section of the manual.

22

5.3 Switching into manual by-pass during operation

Manual by-pass enables the user to isolate the electronic circuitry of the UPS from the mains and the load
without interrupting the load operation by connecting the loads directly to the bypass supply.

This feature is useful while performing maintenance or service and shall only be executed by authorized
technical service personnel.

Maintenance and service may only be performed by authorized technical personnel

Bring the manual bypass circuit breaker (F3) to “ON”/ “I” position.

Make sure that the UPS switches into bypass mode (see “BYPASS” message on the LCD). Voltage,
frequency and waveform of the bypass mains shall be in limits, and bypass shall be enabled for the UPS to
operate in bypass mode.

Bring the input and inrush circuit breakers (F1 and F6) to “OFF”/”0” position.

If the by-pass mains input is separated, bring the by-pass circuit breaker (F4) to “OFF”/”0” position.

Bring the output and battery circuit breakers (F2 and F5) to “OFF”/”0” position.

LCD and buzzer will stop operation in a few minutes.

During manual bypass operation, loads are fed directly from bypass mains. Therefore no
protection against mains disturbances or interruptions is present.

Although all switches except F3 are “OFF” during manual bypass operation, hazardous voltages

are present on the terminals, EMC filters and measurement circuits.

5.4 Returning from manual bypass to UPS

Bring the output circuit breaker (F2) to “ON”/”I” position.

Bring the input and inrush circuit breakers (F1 and F6) to “ON”/ “I” position.

If the by-pass mains input is separated, bring the by-pass circuit breaker (F4) to “ON”/ “I” position.

Bring the manual bypass circuit breaker (F3) “OFF”/”0” position.

See the “NORMAL” message on the LCD.

Bring the battery circuit breaker (F5) to “ON”/ “I” position.

5.5 Connection to a generator

If the input power is supplied by a generator, set the digital input “GEN ON” high. This ensures
generator friendly operation by smoothing the increment of the current drawn from the generator, during
transition from battery mode to normal mode.

When this is done, “GEN ON” alarm will be shown. Connection details are given in the
“communication” section.

6 Operating Procedures for Parallel Systems

6.1 Introduction

EVO DSP UPS Systems are designed according to high MTBF figures with increased reliability
but in case of necessity, a second ( or more ) EVO DSP UPS’s can be connected in parallel redundant
configuration for supplying the very critical load to increase reliability. Maximum of 4pcs of identical
power and specification EVO DSP can be connected in parallel.

If power demand increases in a certain UPS application exceeding the power rating of an already
installed stand-alone UPS, then a second (or more) UPS of the same model and power rating can be
added in parallel to the existing UPS to increase the output power capacity.

The AC inputs of all UPS’s in the parallel system are connected to the same mains, and all the AC
outputs are connected to each other. Each UPS has its own battery group. The critical load is connected
to the common output of the parallel system. There are also some signal cable connections between the
UPS units necessary for parallel operation, and will be described later.

6.2 Procedure for Commissioning and Start Up ( First Installation )

1) If the UPS’s will be converted to parallel systems on site, after installing the parallel kit to each UPS,
calibration of them should be made in single mode initially.

2) Before switching on the UPS’s, make sure that electrical connections have been made as shown in
diagram below:

( OUTPUT CONNECTION OF PARALLEL UPS SYSTEMS )

24

3) The Communication of parallel systems is made through CANBUS. Before starting up the UPS’s, make
the connection of communication cables between UPS’s as per below diagram:

( COMMUNICATION CABLE CONNECTION BETWEEN PARALLEL UPS’s )

CAUTION: Do not remove the communication cables between the UPS’s during parallel operation.

25

In case this communication cable is removed or damaged during parallel operation and the
communication is lost then the slave UPS which can not communicate with the master UPS shall
disconnect its output and maintain the OFF position. The other UPS’s shall continue their normal
operation. In such a case, this UPS should be turned off completely in order to insert its communication
cable again and then switched on again. Do not try to insert the communication cable while it is operating.

3) All switches ( F1, F2, F3, F4(optional), F5 and F6 ) should be in “OFF” (“0”) position.

4) Switch on the input Fuse ( F1 ) of the first UPS ( “Master” or “Number 1” labeled UPS) , Inrush Fuse (
F6 ) should be in “OFF” position. ( Note: if the UPS’s are not factory parallel configured, then any of the
UPS’s can be switched on but one should be configured as master and the remaining UPS’s as slave which
will be explained in detail in the following section )

5) Go to the “CONFIGURATION” section from the front panel menu, enter to “MODE” part and
change it from SINGLE to PARALLEL-1 position. This adjustment is made already at factory set UPS’s.
Then please check and control this during commissioning.

6) By using down button on the same Menu, “N” number should be defined. Parallel EVO DSP series
UPS’s operate according to redundancy principle. At the N+1 configurations, the “N” number in this part
is usually - 1 quantity of the parallel operating UPS qty.

On each UPS, this value should be same and correctly entered. Consequently the amount of load that is
allowed to be connected to total system should not be more than ( UPS qty – N ).

“N” can be defined different than “1”. For example it can be defined as 2 at a 4pcs parallel system.

In this case the system will operate as 2+2 redundancy mode and the total load that is going to be
connected to the system can not be more than ( 2x One UPS Power ).

N Value here can be accepted as minimum UPS qty that is required to supply the load where each ups
operates in full load condition. Then ( UPS Qty ) – ( N ) becomes the redundant ups qty in the system.

The system expects to have at least one more ups than N value. Otherwise it shall provide
“REDUNDANCY LOST” alarm. The same alarm shall also appear in case of

Load % x (N+1) / N > 100 situation.

“Redundancy Lost” alarm is just a warning alarm stating that the load amount shared on the

remaining UPS’s is more now, after the failure of one UPS or after a power increase on the load
side. This alarm shall not affect the normal operation of the total system. It indicates that there is not
anymore a redundant UPS in the total system. In case of a failure on one of the remaining UPS’s, the
system will either go to overload, bypass condition or will shut down totally depending on the UPS
quantity in the parallel system.

7) After defining the UPS number and N value from the Configuration Menu, switch off the UPS and
similarly configure the other parallel UPS’s in the system. After this switch off each UPS again. Each UPS
number should be different. Under this menu; Parallel-1, Parallel-2, Parallel-3 and Parallel-4 options are
available. Maximum 4pcs of UPS can be connected in parallel and at the systems where 4 UPS’s operate in
parallel, each UPS’s numbers should be different, defined from 1to 4. (note: if the UPS’s are factory
parallel configured then each UPS’s number has been already defined, please check and control this )

CAUTION: Configuring the parallel UPS’s with same numbers may cause serious damage during
operation. Make sure that each parallel UPS is configured with different numbers.

26

8) After completing the configuration the Numbers of each UPS and N values, switch on the F1 input
fuse then F4 Bypass Fuse ( if the UPS is split bypass version ) and F6 Inrush Fuse respectively on each
parallel UPS’s.

After seeing “Normal” message on the LCD panel, F5 Battery fuse can be switched on.

Then the output fuses can be switched on accordingly.

The system ( all UPS’s in parallel configuration ) will start operating from static bypass initially, then they
will start supplying the load from inverter.

9) The initially started up UPS will operate as master and the remaining UPS’s will operate as slave.
According the numbers defined for each ups, on the LCD panel, MAS ( master ) and SLAVE (1,2,3,4)
messages should be observed. On the master unit, candidate master ups is also shown as CX.

C represents the best available master candidate UPS among the slave UPS’s and X represents the number
of the slave UPS. In case the master UPS fails, then this candidate assigned UPS becomes master.

6.3 Procedure for Transferring to Static Bypass

In case it is required to transfer the system to Static Bypass, then this process can be made from the LCD
panel of any UPS in the parallel system. In case static Bypass is activated on any UPS, all the UPS’s will
pass to Static Bypass mode at the same time.

In order to pass to static bypass mode, from the LCD panel menu, go to Commands Menu – Extcmnd.

Select the SYS. TO BYP : ENBLD from the menu. In order to do this selection, pressing ENTER button
will be enough. If Enter button is pressed again from any UPS in system ( does not need to be done from
the UPS where it was enabled at the first time) , then the selection will be changed to DSBLD ( static
bypass disabled, again inverter operation starts ).

6.4 Procedure for Transferring to ( Maintenance ) Manual Bypass

In case it is required to transfer the system to Manual Bypass, then this process can be made from any
UPS in the system. In case Manual Bypass is activated on any one of the UPS, all the UPS’s will pass to
Manual Bypass mode at the same time.

In order to activate the Maintenance Manual Bypass, it is enough to switch on the Maintenance Bypass
switch ( F3 ) on any UPS.

To go back to Inverter operation again, it is necessary to switch off the manual bypass switch of the UPS
which was switched to on position in the first place.

6.5 Procedure for Switching OFF

To switch off the System or one of the UPS’s, follow the procedure below;

1) Switch off the Battery Fuse ( F5 )

2) Switch off the Output Fuse ( F2 )

3) Switch off the Input Fuse ( F1 ) and Inrush Fuse ( F6 )

4) Switch off the Bypass Fuse ( F4 ) if exists

Now the UPS or UPS’s can be separated from the system.

27

7 Features and operating limits

7.1 Mains limits for normal operation

Frequency and rms value of the mains input voltage has to be within acceptable limits for the UPS to
operate in normal mode.

Lower limit of the voltage depends on how much the UPS is loaded and it decreases as the load decreases
until it reaches 80 V phase-neutral.

Frequency lower and upper limits and voltage upper limit are fixed.

Voltage and frequency ranges for normal operation are given in the “technical specifications” section of
the manual.

This feature lessens the need to use the batteries. Thus, it increases the battery life and continuity of the
load power.

7.2 By-pass mains limits for bypass operation

Frequency, rms value and total harmonic distortion of the bypass mains input voltage has to be within
acceptable limits for the UPS to operate in bypass mode.

Different rms voltage upper and lower limits are present for the return from another operation mode to
bypass mode. This provides hysteresis and ensures that the device does not change operation mode very
often when the bypass mains rms voltage is close to one of the limits.

Bypass mains limits are software parameters. They can be changed upon request.

7.3 Battery test

This feature enables the user to obtain information about the battery condition. If the batteries have
approached end of their lives, batteries fail.

Battery life depends on several parameters like the number of charge-discharge cycles, discharge depth
and ambient temperature. Battery life greatly decreases as the ambient temperature increases. Therefore it
is recommended to keep the ambient temperature about 20 °C.

To perform a battery test, enter “START B. TEST” in the COMMANDS menu and wait. The UPS will
switch into battery mode, when the test has started. After about ten seconds, UPS will return to the
operation mode before the test. If the batteries pass the test, no alarm will be shown.

If the batteries fail, you’ll receive BATT FAILED message under the ALR submenu. In this case, make
sure that the battery circuit breaker is “ON”/”I”, charge the batteries for minimum 10 hours and repeat
the test. If the alarm persists, consult Technical Service for replacement.

Make sure that the batteries are fully charged and battery circuit breaker is “ON”/”I” before

starting battery test. Otherwise, the batteries will fail even if they are in good condition.

BATT FAILED message will not disappear until another successful test is performed.

28

7.4 Overload behavior

While operating in normal or battery mode, the UPS can feed overloads for a limited duration which is
given in the “Technical Specifications” section. After that duration, UPS automatically switches into
bypass mode, if the bypass is enabled and frequency/waveform/rms value of the bypass mains voltage is
within limits. If the overload situation continues in the bypass operation, thermal/magnetic protection
devices may activate and protect the circuit. In this case, all loads on the output will be switched off.

Make sure that the UPS is not overloaded to provide a higher quality supply to the loads.

7.5 Electronic short circuit protection

The UPS attempts to force the thermal/magnetic protection devices between the output terminals and the
short circuited load to open, by supplying current to the short circuited load for a limited duration. The
UPS must be working in battery or normal mode, for this feature to work.

To enable the short circuit protection feature of the UPS, each load shall be fed over a separate

circuit breaker chosen according to the load current. This should provide quick disconnection of
the short circuited load and operation continuity of the other loads. To obtain maximum
protection, the rating of each individual load circuit breaker shall have the minimum value, which

is enough to carry the full load current continuously.

If the protection device fails to open the circuit in a limited time, the UPS stops feeding current to the
output. “VSECFLR” message is shown on the upper left of the LCD.

29

8 Communication

All related terminals are on the communication interface board (A1). Connector layout is as following:

8.1 RS232 Communication

Only one of the RS232/RS422 communications can be activated at one time. The selection between
RS232 and RS422 communications can be done by setting the COMM parameter in COMMANDS menu,
as desired.

30

8.3 Digital Inputs (UPS OFF and GEN ON)

Voltage to be applied to the digital inputs is 5V DC. Maximum current drawn by each input is 1 mA.

5V DC supply provided on the communication interface board can be used to supply both digital inputs.

Pay attention to the polarity of the voltages applied to the digital input terminals.

Input Function

UPS OFF

If the UPS OFF input is set high by applying 5V DC voltage on the related
terminals, UPS stops generating the output voltage and stops feeding the load.
When the voltage on the digital input is removed, the UPS starts up according
to the normal procedure.

GEN ON

If the GEN ON input is set high by applying 5V DC voltage on the related
terminals, UPS smoothly increases the current drawn from the generator
during transitions from battery mode to normal mode.

8.4 Free Contact Communication

Free contact relay connection cables shall have a cross-section of 1.5 mm2.

Maximum voltage to be applied to the relay contacts is 42V AC rms (sinus) or 60 Vdc. Maximum

contact current depends on the applied voltage and the load characteristic. Both maximum

voltage and maximum contact current corresponding to the applied voltage shall not be

exceeded.

Maximum allowed resistive contact currents for several voltages are given on the table below:

Applied voltage Maximum contact current for resistive load

Up to 42 V AC 16 A

Up to 20 V DC 16 A

30 V DC 6 A

40 V DC 2 A

50 V DC 1 A

60 V DC 0.8 A

Each relay has both a normally open (NO) and a normally closed (NC) contact. One end of these contacts
is common. Normal states of the relay contacts are shown on the figure at the beginning of the
“communications” section.

Relay functions are described below:

Relay Function

ACFR (AC failure relay)

Contacts change position if the rms value or frequency of the
mains voltage is beyond their limits.

BYPR (Bypass relay)

Contacts change position if the UPS is working in the bypass
mode

BUVR (Battery under voltage relay)

Contacts change position if the battery voltages are critically low
to feed the load and the load power is about to be interrupted

SBFR (secure bus failure relay) Contacts change position, if the output voltage disappears

31

9 Maintenance

Batteries, fans and capacitors shall be replaced at the end of their lives.

Hazardous voltage and high temperature metal parts inside even if the UPS is disconnected.
Contact may cause electric shock and burns. All operations except replacing battery fuses shall
be carried out by the authorized technical personnel only.

Some parts inside the UPS (terminals, EMC filters and measurement circuits) are still energized

during maintenance bypass operation. In order to isolate all UPS parts, circuit breakers on mains

and bypass mains distribution panels feeding the UPS and circuit breakers on external battery

cabinet shall be brought to “OFF/0” position. Internal batteries shall also be isolated from the

system.

9.1 Battery fuses

Bringing the battery circuit breaker to “I”/“ON” position before seeing “NORMAL” message on the
LCD may cause battery fuses to blow out.

Battery fuses shall only be replaced with Gould 22x58 aR 660V ultra fast fuse of same rating or
equivalent.

9.2 Batteries

Battery life strongly depends on the ambient temperature. There are also other factors like the number of
charge-discharge cycles and discharge depth.

Battery life is between 3-10 years if the ambient temperature is between 10 – 20 °C. Performing battery
test can provide you with information about battery condition. (See “battery test” section for more
information on battery test)

Danger of explosion and fire if the batteries of the wrong type or number are used.

Do not dispose of batteries in a fire. The batteries may explode. Do not open or mutilate

batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic.

9.3 Fans

The life of fans used to cool the power circuits depends on the usage and environmental conditions.
Preventive replacement by authorized technical personnel every four years is recommended.

9.4 Capacitors

The life of the electrolytic capacitors on the DC bus and the capacitors used for output and input filtering
purposes depends on the usage and environmental conditions.

Preventive replacement by authorized technical personnel every five years is recommended.

32

10 Troubleshooting

This section gives information about the procedures which shall be performed in case of abnormal
operation. If you fail to fix the problem consult authorized technical service with the following
