1 SAFETY RULES
With this document, GE gives to the user all the necessary information about the correct
installation and connection with the UPS units.
Please carefully read this User Manual before installing or operating the equipment.
If any problems are encountered with the procedures contained in this User Manual, please
contact the nearest Service Centre before you proceed.
All UPS installation, maintenance and service work should be performed by qualified service
personnel only.
KNOWLEDGE and FULL compliance of the safety instructions and the warnings
contained in this manual are
THE ONLY CONDITION
to avoid any dangerous situations during installation, operation, maintenance work,
and to preserve the maximum reliability of the UPS system.
NOTE !
“IEMi - Intelligent Energy Management integrated” is available if
enabled at the factory.
Otherwise, only a GE GLOBAL SERVICES FIELD ENGINEER can make
it available on field installations.
In this case, the site upgrade may require the COMPLETE
SHUTDOWN of the UPS system.
Please refer to the “Safety Rules” included in the “User Manual” &
“Installation Guide” of the UPS.
Please read carefully the UPS “User Manual” & “Installation Guide” before
installing or operating the equipment.
If any problems are encountered with the description of this installation
guide, please contact the nearest Service Centre before proceeding.

2 DESCRIPTION
Fig. 2-1 Functional diagram of a Parallel System RPA in IEMi Operation Mode
GE Digital Energy offers the IEMi - Intelligent Energy Management integrated option to optimize
energy cost while maintaining the highest possible reliability for Parallel Redundant Uninterruptible
Power Supply units (max 6).
For Parallel System installations, secured with Redundant Parallel Architecture™ (RPA™), IEMi Operation
Mode saves energy by dynamically utilizing the UPS units as needed to meet the required load without
compromising the power quality to the critical load.
The software will calculate the number of UPS units which are needed for load supply based on
following:
• Redundancy (N+1 or N+2) • System Load • Rectifier status
• Inverter operating time • IEMi Operation Mode programming
Particularly, the UPS control logic determines the minimal set of UPSs required to maintain a reliable
supply to the critical load.
Then, an efficiency optimization algorithm determines the best UPS configuration in order to maintain
the running UPS in their highest efficiency operating region.
Energy losses are reduced by switching the inverter section of one or more units to a stand-by state.
The critical load is fed by the remaining units operating in double-conversion.
As load increases, other units are gradually switched on-line in order to maintain the required
redundancy level.
The IEMi - Intelligent Energy Management integrated option is only available on parallel installations.
It is clear that in order to enjoy the benefits of IEMi operation a system programmed for N+1
redundancy requires a parallel installation of at least three UPSs, while four UPSs are required for N+2
redundancy.
IEMi - Intelligent Energy Management integrated is an option, and it is available only if introduced at the
factory, or if introduced in field installations by a GE GLOBAL SERVICES FIELD ENGINEER.
Benefits of IEMi - Intelligent Energy Management integrated include:
• Higher efficiency (reduced losses) in low-load conditions (efficiency optimization)
• No compromise on power quality (double-conversion operation)
• No compromise on system reliability (redundant operation)

3 SETUP
3.1 CONTROL PANEL – GRAPHIC DISPLAY
Fig. 3.1-1 Control panel – graphic display: UPS functioning in IEMi Operation Mode
Key to switch the Inverter ON ( I )
NOTE !
When IEMi Operation Mode is enabled, control of Inverter status
and selection of the feed path is done autonomously by the UPS
control logic.
Therefore, Inverter ON / Inverter OFF commands are disabled
when IEMi Operation Mode is enabled.
Key for Inverter shutdown ( O )
Press the key to transfers the Load to Utility/Mains.
Keep pressed for 5 seconds to shutdown the Inverter.
This key is also used as the EPO (Emergency Power Off) reset.
NOTE !
Inverter OFF command is disabled when IEMi Operation Mode is
enabled. Furthermore, all functions associated with the ( O ) key
are disabled – including the EPO reset.

The LCD screen, after 5 minutes of inactivity, shuts down the backlight.
To reactivate it, it is sufficient to press any pushbuttons.
If the keypad remains inactive for 5 minutes or longer, during the viewing of a screen such as
MEASURES, ALARMS, SETUP or COMMANDS, the LCD screen returns automatically to the main screen.
It is possible to view any pushbutton functional description by pushing the button for more than 3
seconds.
Pushing the key “METER” (1st button) and “ALARM” (2nd button) together automatically sets the LCD
communication language for “ENGLISH”.
