RPA™ - Redundant Parallel Architecture™ Parallel System
GE’s Critical Power provides a unique technology called Redundant Parallel Architecture™ (RPA™) that
can parallel Uninterruptible Power Supply (UPS) modules with true redundancy.
With RPA™, there is no need for external electronics or switches to control the UPS modules in the
parallel system.
One of the UPS modules in the system arbitrarily takes a leadership role, while the other UPS modules
have access to all control parameters.
If one UPS fails to operate, the load is automatically redistributed among the others.
If the lead UPS fails to operate then a different UPS automatically takes on the leadership role.
The RPA™ systems are designed to have no single points of failure, ensuring the highest level of power
protection for critical loads.
Extremely flexible
Tailor made power protection to meet your individual installation requirements; TLE Series 225 - 500

Fig. 4.1-1 Block Diagram TLE Series 225 - 500
4.1 BLOCK DIAGRAM AND MAIN ELEMENTS
The TLE Series 225 - 500 system can be divided into the following main elements:
Control System
TLE Series 225 - 500 is designed with microprocessor-controlled signal processing circuits.
The interface between the operator and the unit is provided by the monitoring system on the front
panel.
This monitoring system consists of an active mimic diagram, a keyboard and a backlit display.
Rectifier
The Active IGBT Rectifier converts the 3-phase utility voltage into a controlled and regulated DC-voltage,
supplying the inverter and to charge the battery through the battery-charger.
Thanks to modulation strategy applied to IGBT Bridge, the rectifier provides clean input power in terms
of low THDi and unity power factor.
Inverter
The Inverter converts the DC voltage into a three-phase AC-voltage with constant amplitude and
frequency, which is completely independent and isolated from the AC-input voltage.
Automatic Bypass
The Automatic Bypass consists of a static semiconductor-switch (SSM: Static Switch Module), used to
provide an uninterrupted transfer of the Load from Inverter to Utility.
Back-feed Protection
All TLE Series 225 - 500 UPS's are equipped with an automatic system for the protection against voltage
back feeding towards Utility, through the Bypass (UL 1778 and CSA C22.2 no. 107.3).
This protection works automatically by opening contactor K6 (in series with the thyristors of the static
switch) and eventually K7, and acts in case of internal defects of the system, or due to wrong
manipulations on the Manual Bypass Q2.
Manual Bypass
The Manual Bypass consists of a pair of manual switches (Q1 and Q2), which removes the UPS from the
Load for maintenance, while still supplying the Load with power directly from the Utility.
Battery
The Battery supplies the DC power to the Inverter when the Utility is out of acceptable tolerances.

Under normal conditions the Load is
permanently powered by the inverter with
constant amplitude and frequency.
The Rectifier, powered by the Utility, supplies
the inverter and the battery-charger keeps the
battery fully charged.
The inverter converts the DC voltage in a new
AC sine wave voltage with constant amplitude
and frequency independently from the input
Utility Power.

eBoost™
e High efficiency (up to 99%)
Boost Fast power transfer (< 2ms)
When the eBoost™ Operation Mode is
selected, and the Utility Power is available,
the Load is normally powered through the
Automatic Bypass.
When the Utility Voltage is detected out of the
prescribed tolerances, the Load is
automatically transferred to the Inverter.
When the Utility recovers, the Load returns to
the Automatic Bypass after a variable time
defined by the control unit.
Fig. 4.2.2-1 Block diagram eBoost™ Operation Mode
The eBoost™ Operation Mode can be used for single units or the RPA Parallel System, for up to 6 UPS
modules, with all units individually able to supply power through a redundant communication bus.
The eBoost™ Operation Mode can be configured directly by the user for higher efficiency, considering
the Utility reliability and criticality of the Load.
The selection between the two operation modes “VFI mode and eBoost™ Operation Mode”, or switching
between operation modes at required time, can be done through the UPS control panel (see Section 6.4
/ eBoost).
NOTE !
The eBoost™ Operation Mode is available only if enabled at the factory or by a GE
GLOBAL SERVICES FIELD ENGINEER.

When the Utility is no longer within acceptable tolerances,
the Battery will provide the DC power to the Inverter.
The Inverter will maintain continuous AC power to the
Load until the Battery Voltage reaches the lower limit of
the Inverter operation capability.
During the discharge, the LCD screen shows the estimated
time the Battery can support the critical Load.
Prior to complete Battery discharge, the "stop operation"
alarm (shut-down imminent) warns the operator that the
Battery is almost discharged and the UPS is about to shut
down.
Fig. 4.2.3-1 Block diagram Utility Failure operation
In case of RPA Parallel System
With a Parallel System for power capacity (see Section 4.3)
With the Bypass Utility power available, a “Battery low” warning on any unit will cause the Load
to be transferred to Utility (after a selectable time delay).
With Bypass Utility power not available, a “Battery low” warning on any unit will start the “stop
operation” timer (adjustable).
The Load will shut down at the end of the “stop operation” time period.
With a Parallel System for redundancy (see Section 4.3)
When a Battery low warning occurs on a unit not necessary to support the present Load, this unit
will shut down after a timeout period (selectable).
The Load is shared between the other units.
As the warning occurs on one unit necessary to support the present Load, the system starts the
"stop operation" timeout (selectable).
The Load will shut down at the end of the “stop operation” time period.
As soon as the AC input power recovers, the Rectifier will
start automatically, supplying DC power to the Inverter
and recharging the Battery.
If the Inverter was previously shut down due to low
Battery, the Load will be initially powered by Utility
through the Automatic Bypass.
When the Battery is sufficiently recharged to ensure a
minimum time of operation with the present Load, the
Inverter will start automatically and the Load will be
transferred back to the Inverter.
Fig. 4.2.4-1 Block diagram Utility recovery operation
In case of RPA Parallel System
When the AC input power recovers, the Rectifiers will start-up sequentially, according to their
number in the Parallel System. This minimizes the initial inrush current.
The Inverters will start-up automatically, but only when the Battery has been sufficiently recharged
for a minimum runtime with the present Load.
When enough Inverters to supply the Load have been restarted, the Load will be transferred from
the Automatic Bypass back to the Inverter output.

In normal operation, the Load is supplied by the
Inverter.
When the control system detects a fault in the
Inverter, an overload condition or a short-circuit
condition, the Automatic Bypass will transfer the
critical Load to the Utility without interruption.
When the Inverter recovers, or the overload or
short-circuit condition is corrected, the Load will
be automatically transferred back to the Inverter.
Fig. 4.2.5-1 Block diagram Automatic Bypass
If the UPS is unable to return to normal mode following an automatic transfer to Bypass mode, an
alarm condition will be initiated.
A Manual Bypass (operator initiated) will not be considered as an alarm condition.
In case of RPA Parallel System
Each unit has its own internal Bypass.
These units are continuously exchanging information, enabling all of the internal Bypass circuits in a
Parallel System to operate simultaneously.
If the Inverter of a unit fails, its Bypass circuit remains available to the Parallel System.
It is excluded only if the unit is separated from the common bus by opening its output switch Q1.
The Manual Bypass circuit consists of manual
switches Q1 and Q2, which permits transfer of
the Load directly to the unconditioned AC power
without interruption, leaving the UPS available
for maintenance.

4.3 RPA PARALLEL SYSTEM OPERATION
4.3.1 Introduction to the RPA Parallel System
Two or more equal power units can be paralleled to increase the output power (paralleling for capacity)
or to improve the overall reliability of an UPS system (paralleling for redundancy).
The outputs of parallel units are connected to a common power bus, and in normal operation the units
connected on the parallel bus share the Load equally.
The modular concept of TLE Series allows parallel operation of up to 6 units, without using paralleling
switchgear, external bypass circuits or common control circuitry (see Fig. 4.3.1-1).
Parallel units for power capacity
Several units can be paralleled in order to achieve output power greater than the maximum power of a
single unit.
The maximum total power shared between the paralleled units is equal to the total installed nominal
power.
In the event of a failure of one unit, the power supplied by the UPS system becomes insufficient and the
Load will be transferred to the Utility Bypass source.
Parallel units for redundancy
The nominal power rating of the n out of n+1 redundant paralleled modules must be equal to or higher
than the required Load power.
The Load will be equally shared by the n+1 units connected on the output bus.
Should one of the n+1 paralleled units trip Off-line, the remaining (n) modules will supply the Load,
maintaining conditioned power to the critical Load.
From this results higher reliability and security for the Load plus a higher MTBF (Mean Time Between
Failures).

User Manual TLE Series 225 - 500 UL S1
NOTE !
It is strongly recommended that no transformers, automatic circuit breakers or
fuses should be installed between the units output and the Load common bus bars.
However, it is recommended that a disconnection or isolation switch is installed in
order to totally isolate a unit if needed.
4.3.2 Features of RPA Parallel System
The TLE Series 225 - 500 Parallel System is designed to provide a complete Redundant Parallel
Architecture, and is free from common equipment.
Not only the Inverters but also the Bypass functions are redundant.
When one UPS needs maintenance or service, the Load is powered by the other units.
The redundant communication bus to which all units are connected keeps each unit informed about the
status of all the other units.
The control panel located on each unit allows controlling and monitoring the status of this unit.
4.3.3 System control
A high-speed redundant, serial communication bus, guarantees the exchange of data and thus the
communication between the CPU's of each unit.
Each module controls is own function and operational status and communicates with all other modules,
in order to act or react if necessary, adapting to the new conditions.
4.3.4 Synchronization
All units are identical, but one unit is arbitrarily selected as the reference and all the other units
synchronize to this unit, which in turn synchronizes to the Utility Bypass voltage, as long as the latter is
within tolerances.
In case of reference failure, another unit in the Parallel System is automatically chosen to take over the
reference role.
The Bypass Input for all the units of the Parallel System must be supplied from the same AC source (no
phase shift allowed between them).
4.3.5 Load sharing
On each unit of the Parallel System, Inverter Output Voltage and Current are measured and applied to a
Load sharing bus.
An eventual difference between the units is therefore automatically equalized.

propagated to all units in the RPA Parallel System.
The activation / deactivation of eBoost™ Operation Mode is indicated each time in the event list.
In order to check the inverter function, at least 1 minute of VFI mode must be programmed during the
week (the Yes/No parameter is automatically disabled if this condition is not satisfied).
In case this minimum time in VFI mode is not respected, the eBoost™ Operation Mode will be disabled.
If the value is “No”, the UPS is normally operating in VFI / double conversion mode at all times.
When the UPS is in eBoost™ Operating Mode the eBoost LED is ON (green

For the weekdays from “Monday to Sunday”, the edit mode (edit day) allows to define time intervals
when the UPS is operating in eBoost™ Operation Mode. The hour is given in 24-hour format.
These intervals are defined by:
Start Time: The hour of the day after which the eBoost™ Operation Mode is enabled.
The eBoost™ Operation Mode is enabled until the following “Stop Time” time is reached
(the “Stop Time” time of the same day if this is later than the “Start Time” time, the “Stop
Time” time of the following day otherwise).
Stop Time: The hour of the day before which the eBoost™ Operation Mode is enabled.
The eBoost™ Operation Mode is enabled starting from the preceding “Start Time” time (the “Start Time”
time of the same day if this is earlier than the “Stop Time” time, the “Start Time” time of the previous
day otherwise).
Identical times for “Start Time” and “Stop Time” maintain the existing mode only in case the previous

3-ph SNMP/WEB plug-in adapter
SNMP - Simple Network Management Protocol
The 3-ph SNMP/WEB plug-in adapter is an interface to the Ethernet
Network, and provides UPS information via the standard SNMP
Protocol (UPS-MIB (RFC-1628); GE Single MIB; GE Parallel MIB).
The UPS can therefore be managed by a Network Management
System (NMS) or by our applications (for instance GE iUPSGuard or
GE Data Protection), which uses this information to determine the
state of the UPS in order to guarantee safe and orderly shutdown of the server, when needed.
GE iUPSGuard
GE’s iUPSGuard is a remote monitoring solution for UPS, providing
status monitoring and alarm notification that supports all GE UPS
product lines, anytime, anywhere.
iUPSGuard provides current and detailed information about UPS
operation, including its configuration, internal alarms and
operating conditions over web.
iUPSGuard notifies personnel of critical alarms and events via
email or SMS, allowing a user or GE technician to make timely
decisions on critical conditions.
In addition, comprehensive data collection and analysis improves
diagnostics capability and enhances response time.
Continuous monitoring and ongoing maintenance help ensure
maximum performance of your UPS equipment as it protects
business critical applications.
GE Data Protection
GE Data Protection software can communicate with the UPS over
RS-232, USB or SNMP to receive status information and
measurement values of the UPS. In case of a critical condition
(time on battery, remaining battery autonomy time or low battery)
for the Load, the software starts a controlled shut-down.
An enhanced alarm management system provides the possibility
to start applications, send messages, and send e-mails for every
upcoming or disappearing alarm.
eBoost™ Operation Mode
High efficiency operating mode, where the load is supplied directly by utility
and automatically transferred to inverter if the voltage is out of prescribed
tolerances.
RPA Kit
Redundant Parallel Architecture
Up to 6 units parallel possible for redundancy or capacity in RPA
configuration.

WARNING !
All maintenance and service works must be performed by QUALIFIED SERVICE
PERSONNEL.
9 MAINTENANCE
9.1 MAINTENANCE
A UPS system, like other electrical equipment, needs periodic preventive maintenance.
A regular maintenance check of your installation guarantees higher reliability of your safe power supply.
GE’s Critical Power recommends to perform the first service within 12 months from the commissioning
date or within 18 months from delivery date.
Subsequent services to perform every 12 months.
Preventive maintenance work on the UPS can be done only by trained SERVICE TECHNICIANS.
We therefore recommend you sign a Maintenance and Service contract with the local Service Center
organization.
9.1.1 Service check
If this lamp lights up during normal operation, the unit has not been serviced for the last 20,000 hours by
a GE TRAINED TECHNICIAN.
Some components of the UPS which need periodic maintenance, if not replaced, could cause a reliability
reduction of the supply system
We highly recommend that you contact your Service Center for preventive maintenance work.
9.1.2 Fans and ventilation
We recommend a periodic cleaning of the ventilation channels and grids on the UPS system, in order to
guarantee proper air circulation in the unit and in the Battery.
The fans eventually wear out and must be substituted when a UPS alarm is triggered, in order to ensure
the reliability of the UPS
9.1.3 Other components with limited lifetime
Various components, such as the DC and AC filter capacitors and the lithium battery on the “P3 -Control
Panel” (memory saving), must be systematically substituted in order to maintain the UPS’S reliability.
The substitution of these components is signaled by a UPS alarm going off.

User Manual TLE Series 225 - 500 UL S1
NOTE !
Ask to your local Service Center to submit the form of Preventive Maintenance
Contract suitable for your specific needs.
9.1.4 Battery
We recommend a periodic Manual Battery Test, especially if the Automatic Battery Test is disabled, in
order to verify if the Battery can provide the expected backup time in case of Utility Failure.
We recommend that this test is performed at least every 3 months, especially if the Battery is not
sufficiently discharged during normal operation.
The discharge time you use should be at least half of the Battery runtime.
For Automatic Battery Test setting, a special code is required to enter user set-up parameters.
The start-up technician has access to this code and can program this feature during start-up.
Please consider that, if you did a full Battery Test to verify the full runtime of the Battery, the charger
needs at least 8 hours to recharge the Battery up to 90% of its capacity.
Long shut-down periods of the UPS system
To guarantee that the Battery is fully charged, the UPS system should be in operation for at least 12
hours every 3 months.
If not the Battery may be permanently damaged.
9.1.5 UPS room conditions and temperature
The UPS room and the Battery Room have to be maintained clean and free from dust.
A high temperature of the UPS room and of the Battery Room affect the lifetime of several components
inside the equipment.
The Battery is very sensitive to room temperatures above 77°F (25°C).
9.1.6 Preventive maintenance program
a) Cleaning, a visual inspection and a mechanical inspection of the UPS modules.
b) Replacement of defective parts or the preventive replacement of parts with a defined lifetime.
c) “Updating” of the equipment (technical improvements subsequent to the delivery).
d) Check the calibration of DC voltage and Inverter Output Voltage and Frequency.
e) Check of the settings of the electronic regulation, the control and the alarm circuits of the
Rectifier(s) and Inverter(s).
f) Functional checks on Thyristors, Diodes, Transformers, Filter Components, e.g. to ensure that they
are operating within the specified design parameters.
g) Overall performance test including a Utility Failure simulation with and without the Load.
h) Monitoring Battery operation in discharge and recharge mode including any boost charge duties.
