EXTERNAL REPO BUTTON
REPO input is the screw terminal pair at the rear next to the RS232 connector. The function of the REPO input
can be programmable from ADJUST MENU. The selectable options are:
Function Description
NO contact If REPO input terminals are shorted emergency power off will applied
NC contact If REPO input terminals are opened emergency power off will applied
This isolated input is used to turn off the UPS remotely in case of emergency.
The UPS is supplied from the factory with REPO terminals open-circuited ( see “View of the UPS connections”)
if those two (NO) terminals are shorted, UPS shuts-down the output voltage.
In case of emergency ,by activating the stop device, the UPS enters to stand-by mode and powers-off the load
completely.
The REPO circuit is self-powered ,no external power supply voltage is therefore required. If the external REPO
switch is pressed (at least 1 second) UPS turns off its output.
WIRING PROCEDURE
1. Remove the metal guard on the input/output terminal group and connect phase ,neutral and earth input
cables. During connection match phase cable to phase input ,neutral cable to neutral input , earth cable to
earth input.
Input Power Connections
2. For output connections you have three outlets at the back of the UPS
- Two IEC output sockets are available. You can directly plug the load cable into anyone of these outputs.
- If the output will be connected to the load distribution system directly, you can use screw terminal outputs.
During connection of the load, match phase cable to phase output, neutral cable to neutral output, earth
cable to earth output terminals.
Reassemble the metal guard removed previously.

11
Output Connections
3. If external batteries are used , turn off the battery fuse and plug on the battery cable to the external battery
socket on the rear panel of the UPS.
External battery connection
4. Also proper control and signal wire connections (alarm relays, REPO etc.) should be made through the
screw terminal block shown in figure 11.
Note :These auxiliary cables must be shielded and double insulated. (Recommended cross-section =1mm
2
)
PROTECTIVE EARTH
The protective earth cable must be connected to the earth connection terminal and bonded to each cabinets in
the system and also the earthing and neutral bonding arrangements should be in accordance with the local
laws. Proper grounding considerably reduces problems in systems caused by electromagnetic interference.
ATTENTION!!! Failure to follow adequate earthing procedures can result in electric shock
hazard to people or risk of fire.

III. OPERATION
DESCRIPTION
The purpose of the UPS is to provide constant power which is in predefined limits. While the input voltage is in
acceptable tolerances, UPS converts the AC mains input voltage to DC voltage , then inverter stage will
convert to AC output voltage again. If the mains input voltage is no available or out of tolerated limits, the UPS
uses the DC power from batteries and generates stable AC output voltage.
So the inverter stage always produce stable AC voltage and frequency for supplying critical loads connected to
the UPS output.
On the other hand, a static bypass system keeps an AC supply (bypass supply) ready to apply immediately to
the output in case of overloads or UPS failures.
PROTECTIONS INSIDE THE UPS
OUTPUT SHORT CIRCUIT PROTECTION
In the event of a fault on the load , like short circuit, UPS shuts-down the output voltage and do not transfer the
load to bypass to protect the bypass source. To restart after a short circuit ,find out the short circuit on the load
side and disconnect it from the output of the UPS. Then restart the UPS again.
OVERLOAD PROTECTION
An electronic overload protection system is available in the UPS. This protection system has 3 levels:
100%-125% load UPS operates for 10 minutes then transfers the load to bypass (adjustable time)
126%-150% load UPS operates for 1 minute then transfers the load to bypass (adjustable time)
If the load is greater then 150% UPS immediately transfers the load to bypass
FUSES
There are some fuses on the UPS:
Power supply fuse (on-board glass fuse)
Static bypass fuse (on-board glass fuse)
Mains input fuse (S2-MCB)
Battery fuse (S3-MCB)
Output fuse (S1-MCB)
OPTIONAL bypass input fuse (S4-MCB)
BATTERY PROTECTION
Deep discharge protection.
Battery charge current limit (adjustable)
