source. Do not expose UPS to rain or liquids in general. Do not introduce any solid objects.
*Avoid dusty environments or areas where dust of conductive or corrosive materials is present.
*Air outlets of the UPS are on sides, front and back. Leaveat least 75 cm at the front and both
sides and 50 cm at the back for maintenance and ventilation.
5.4.2 Electrical Reguisites
The installation must comply with national installation regulations.

Load leakage currents are added to those generated by the UPS. If loads with high leakage
currents arepresent, adjust this value accordingly.
It is recommended to adjust the protective device after measuringthe 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 protectionadequately.
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 afault
voltage on the UPS. The label shall carry the following wording:
5.5. 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.
Check adequacy and appropriateness of your electrical installation before operating your device.
Check whether your insurance line is inserted at the beginning of the electrical installation and the
fair value . LEGA PLUS Series UPS 3 -phase input ( 380VAC , 50Hz ) is working with mains voltage.
Abnormal fluctuations in the mains voltage value , long-term if not decrease more than 10% , the
device can work at the desired capacity. Connect the plug / cable to the network by the shortest
route possible .
Make sure to ground ! If your device has a protection device against overcurrent . However, use
appropriate insurance value to avoid damaging your network.
Select the cable to power devices in the appropriate section and fuse selection from the table.
(Page 5)
Before starting the installation of all circuit breakers to "OFF" / "0" Make sure the location.
The battery terminals of the device internal battery which can be dangerous voltages.

The unit should be ground to be safe and reliable work . Before connecting other cables PE
grounding plug connectors.
PE terminals of the load will depend on the UPS output to protective earth terminal. If the external
battery cabinet must be grounded through the protective earth terminal of the UPS battery .
5.5.3 Mains ( Input ) Connections;
Mains connection of the UPS will be connected to PE,N,R,S,T terminals. Auto fuse in the distribution
panel where the other side of the cable which will be connected,should be connected to phase and
neutral and it can be disconnected at the same time.
In addition, if there is 30mA leakage relay on the distribution panel, connection should be done on
the mains side of this relay.
Automat should be D-type and its value should be selected in accordance to the maximum current
which shown on the technical specifications.
For life safety, battery automat, input and output automat taken to the ‘0’ position. Firstly the
aoutomat of the loads taken to ‘I’ position one by one.When installing the UPS, follow these steps
carefully.
*When installing the UPS, never switch the battery fuse to “I” position as a first step.
*After finished the all connections, switch the mains input automat to “I” position.
*Please see the DC bus voltage exceed 350 VDC from front panel. This condition shall not exceed 5
seconds, depending on the mains voltage.
*After that switch the battery and output automat to “I” position respectively.
*After completion of these transactions, UPS will be on operate and the loads will begin to be fed
uninterrupted.
*When the UPS is first activated the backup time can be shorter than the calculated. For this reason,
before using the UPS, we recommend to recharge the batteries 10 hours.
When you activated the UPS, please enter the ALARMS menu and check any written alarm.
When the UPS connected to the mains voltage, there will be automatically voltage at the output of
the UPS.

SERIES 10-250 kVA UPS USER MANUEL PAGE 9
5.5.4 Load ( Output ) Connections;
The connection of the loads to the UPS will be connected to R, S, T, N, PE terminals. Loads to be fed
more than one, the appropriate value automats should be choosen for each of these loads.
The cables between the loads and ouput terminals should be appropriate cross-section. To enable
the short circuit protectionfeature 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 minumum value, which is enough to carry the full load current continuously.
You should get power cable of the loads from the distribution panel.
Activate the loads now.
Rated apparent and active power of the loads shall be less than the UPS power ratings.
