*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 adequately.
According to EN 62040-1-2, the user shall place a warning label on the input distribution panel
and the other primary power isolators, in order to prevent the risk of electric shock caused by a
fault voltage on the UPS. The label shall carry the following wording:
Isolate uninterruptible power supply before working on this circuit
2nd5 Connections
Connections shall be done by authorized technical staff only.
When the UPS is brought from a cold place to a warmer place,
humidity of the air may condensate in it. In this case, wait for
two hours before beginning with the installation.

2nd5.1.2 Input Connection
Bring the circuit breaker on the distribution panel to “OFF” or “0” position before making the
connections
Connect the phases to input (X2) L1, L2 and L3 terminals.
A definite phase sequence is needed for the UPS to operate. If you encounter “IN SEQ FLR” alarm at
start up, decommission the UPS, make the protection devices on the input distribution panels “0”/”OFF”
and interchange any two phase cable.
Connect neutral to N terminal of X2.
2nd5.1.3 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.
2nd5.1.4 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 the batteries of the wrong type are used.

14
2nd5.1.5 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.
2nd5.2 Communication Interface Connections
Related information is given in “communication” section.

15
3Modes 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.

16
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.
3rd1 Bypass Mode
Devices without separate bypass mains input, absorb energy 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 in 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
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 in their tolerance limits. If the
bypass voltage goes beyond these limits, the UPS switches into normal operation.
Bypass mode doesn’t 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 doesn’t provide electronic short circuit protection like in normal mode. If a short
circuit or occurs on the output during bypass operation, the thermal/magnetic protection will act
and all loads will be deenergized.
Prolonged overloads may cause the thermal/magnetic protection act. In this case, all loads will be
deenergized.

17
3rd2 Normal 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 in 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 in acceptable limits.
3rd3 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 in 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.
