3 INTRODUCTION
The TLE Series 160 - 500 Uninterruptible Power Supply (UPS) provides the energy supply for critical loads which need a reliable, continuous free from voltage disturbances and frequency fluctuations supply.
In case the power provided by the Utility Fails , or exceeds the permitted tolerances, the power to supply the Load is provided by the Battery for the specified time at the rated Load (or longer at a reduced Load ) or until the Utility power returns.
TLE Series 160 - 500 is a truly VFI double conversion Uninterruptible Power Supply
(UPS), equipped with automatic bypass, where the Load is normally supplied by the
Inverter .
If the Inverter is not able to supply the required Output Voltage , or when overload or short-circuit on the output occur, the Load is instantly transferred to the Utility via the Automatic Bypass .
The UPS automatically returns to normal mode when the failure condition is restored.
TLE Series 160 - 500 can be configured, if chosen, for the eBoost™ Operation Mode
(Option - High efficiency: up to 99% / Fast power transfer: <2ms) permitting maximum energy saving.
KEY FEATURES :
More Critical equipment supported
Rated at 1 Power Factor, TLE Series 160 - 500 delivers more real power than other UPS in the market.
With today’s trend toward power factor corrected loads, TLE Series 160 - 500 can support more total
Load than any other UPS available, allowing you to support a greater number of today’s enterprise computing Power Factor Corrected (PFC) equipment.
High Efficiency
Thanks to type Advanced Neutral Point Clamped three level IGBT technology, TLE Series 160 - 500 guarantees a high overall performance.
Intelligent Energy Management (IEM) combined with RPA , results in the most cost efficient and reliable
UPS solution in the industry.
Fully digital
Digital Signal Processor (DSP) , Flash memory and Advanced Neutral Point Clamped are the technology corner stones of a new age of power quality and power reliability.
RPA™ - Redundant Parallel Architecture™ Parallel System
GE 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 160 - 500 offers various options like EMC filter and our comprehensive software for mission control and data protection to cover all your application needs.

4.1
BLOCK DIAGRAM AND MAIN ELEMENTS
Fig. 4.1-1 Block Diagram TLE Series 160 - 500
The TLE Series 160 - 500 system can be divided into the following main elements:
Control System
TLE Series 160 - 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 160 - 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.
Battery
The Battery supplies the DC power to the Inverter when the Utility is out of acceptable tolerances.

OPERATION MODES
4.2.1
Normal VFI Operation Mode (Voltage Frequency Independent)
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

4.2.2
eBoost™ Operation Mode (option)
Fig. 4.2.1-1 Block diagram normal VFI Operation Mode 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
Fig. 4.2.2-1 Block diagram eBoost™ Operation Mode defined by the control unit.
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 .

4.2.3
Utility Failure Operation
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.
4.2.4
Utility Recovery Operation
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.

4.2.5
Automatic Bypass
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 shortcircuit 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 Fig. 4.2.5-1 Block diagram Automatic Bypass the Inverter .
If the UPS is unable to return to normal mode following an automatic transfer to Bypass mode , an alarm condition will be initiated.
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 .

RPA PARALLEL SYSTEM OPERATION
4.3.1
Introduction to the RPA Parallel System
Fig. 4.3.1-1 Block diagram RPA Parallel System operation
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).

4.3.2
Features of RPA Parallel System
The TLE Series 160 - 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.
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.

IEMi Operation Mode (option)
NOTE !
IEMi and eBoost Operation Mode are mutually exclusive; they cannot be simultaneously available on a system.
Fig. 4.3.6-1 Functional diagram of a Parallel System RPA in IEMi Operation Mode
GE 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) • Rectifier status
• Inverter operating time
• System Load
• 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).

UPS PARALLELED ON THE SAME BATTERY
NOTE !
A Parallel System with a Common Battery for two or more UPS (max. 4 units), requires a particular installation and adequate setting of some parameters, (accessible only through password), and can therefore only be done by a GE QUALIFIED ENGINEER.
Usually each UPS Unit runs with its own Battery .
In case of parallel units running with a Common Battery (max. 4 UPS - see Fig. 4.4-1 ), the sharing circuit between the individual UPS is integrated in the communication bus of the system in order to assure an equal sharing of the Rectifiers output currents.

Pay attention to the following recommendations:
• The units delivered for this functioning mode needs special parameters setting, so they must be prepared in advance before the installation.
• The installation must be performed only with the UPS system completely shut down.
• The AC Rectifiers input power (4) must be the same, with clockwise phase rotation for each unit.
• Each Rectifier must be set for the same floating DC voltage and the same Battery current limitation.
• It is mandatory to install the fuses / MCB (6) on each line connecting the Rectifiers to the common
Battery for maintenance / safety reasons (see Installation Guide to Section 4.8.2
).
• In case a unit must be powered down for maintenance, switch-OFF the concerned unit before open the DC fuses / MCB on the Battery line (6).
• It is recommended to connect an external NO free contact “Battery Fuses” to the UPS and to enable the function by setting the parameter (see Section 9.1
).
• If an emergency generator set supplies the UPS, and the free contact “Generator ON” is connected to the Customer Interface , connect a separate NO free contact on each parallel unit.
• The parameters enabling the Battery test , both manual and automatic, must be set in the same mode on all the units sharing a Common Battery .
• Do not connect the temperature sensor for automatic battery floating voltage compensation.
• Do not enable the function Boost charge .

Description
K6 open despite a closing command being issued.
Signaled by auxiliary contact.
The Load cannot be supplied by Automatic Bypass.
K6 closed despite an opening command being issued. Signaled by auxiliary contact.
A faulty current has been detected in the staticswitch causing the opening of the contactor K6 for
10 seconds.
After 3 times K6 remains definitively open.
Only a GE Service Technician can reset the alarm.
The Utility Bypass Voltage is out of the tolerances ( ±
10%).
K6 opens, synchronization with Utility is inhibited and transfer to Utility is blocked.
K3 open despite a closing command.
Inverter is switched OFF.
It can be restarted manually after recovery of the alarm condition.
K3 not open despite an opening command.
Be aware the DC Capacitors could remain charged.
The Load supplied by Utility exceeds the Inverter power.
The Load remains supplied by Utility until the alarm stays ON.
The Fan Control Board indicates a malfunction of one or more ventilators.
Load is locked on Utility because 3 transfers on
Utility have been detected in a short time (default 30 sec.).
The transfer will be free after a time defined in parameter (default 30 sec.).
Load is transferred to Utility because the error detector detected a disturbance on the output voltage.
Alarm after detection of an “EPO - Emergency Power
Off” from an external safety device connected on
Customer Interface Board.
Consequently K4, K6, K7 open, Rectifier, Inverter and
SSM are switched Off.
The UPS system is in an overload condition > 105% on Inverter, or > 150% on Utility.
With Utility unavailable, a sequence of “stop operation” starts.
Time out depends on degree of overload.
With Utility Bypass supply available and Load
> 115%, the Load is transferred on Utility.
Load will be transferred again automatically on
Inverter when Load < 100%.
The voltages of Utility and Inverter are not synchronized, which causes the opening of K6.
The propagation of the eBoost / IEMi configuration to other units in a Parallel System failed.

8 OPTIONS
8.1
CONNECTIVITY OPTIONS
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 shut-down 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 Service 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.
8.2
OPTIONS IN UPS CABINET
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.
IEMi Operation Mode
High efficiency operating mode for RPA installations operating in low load conditions, where the efficiency is maximized by switching one or more units to a stand-by state, thereby driving the on-line units towards their higher efficiency operating region.
RPA Kit
Redundant Parallel Architecture
Up to 6 units parallel possible for redundancy or capacity in RPA configuration.

9 MAINTENANCE
WARNING !
All maintenance and service works must be performed by A GE Service Technician.
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 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 a GE Service Technicians .
We therefore recommend you sign a Maintenance and Service contract with the local GE 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 Service 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 GE Service Center for preventive maintenance work.
NOTE !
Never ignore a Service Check alarm!
Failure to perform mandatory preventative maintenance on components documented in the UPS product manual may result in thermal damage to the equipment, its surroundings, and an increased risk of personnel injury.
Refer to Section 9.1.2 to 9.1.6 for this important detail.
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.

Battery
NOTE !
Perform mandatory battery maintenance per battery’s manufacturer product manual. This includes electrical and thermal measurements, inspection, cleaning, replacement and re-torque of connections.
Failure to perform proper maintenance on the battery, per the battery manufacturer’s recommendation, including scheduled battery replacement, may result in thermal damage to the equipment and an increased risk of personnel injury.
GE declines any responsibility for any damage to the system and the surrounding caused by battery when the battery maintenance program is provided by other than
GE itself and GE authorized partners.
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 & Manual 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.
NOTE !
Ask to your local GE Service Center to submit the form of Preventive Maintenance
Contract suitable for your specific needs.
