3 INTRODUCTION

An Uninterruptible Power Supply (UPS) provides the power for critical loads that need a reliable, continuous, disturbance free 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.

SG Series 400 & 500 is a true double conversion VFI (Voltage Frequency Independent) UPS system where the Load is continuously supplied by the Inverter through the Rectifier.

In case of trouble on the Inverter 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.

Key features:

• More Critical equipment supported Rated at 0.9 Power Factor, SG Series 400 & 500 delivers more real power than other UPS in the

market. With today’s trend toward power factor corrected loads, SG Series 400 & 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.

• No single point of failure Redundant Parallel Architecture (RPA) is an exclusive GE technology.

With RPA, SG Series 400 & 500 UPS are controlled in a true peer-to-peer configuration where all critical elements and functions (including Bypass) are redundant. SG Series 400 & 500 is designed to be the most reliable power protection system available on the market today.

• High Efficiency Using IGBT technology and Space Vector Modulation (SVM) strategy, SG Series 400 & 500 offers low

output voltage distortion and provides efficiencies up to 93%.

• Fully digital Digital Signal Processor (DSP), Flash memory and SVM strategy, are the technology corner stones of new age of power quality and power reliability.

• Extremely flexible Tailor made power protection to meet your individual installation requirements; SG Series 400 & 500 offers various options like input harmonic filters and our comprehensive GE Power Diagnostic software suite for mission control and data protection to cover all your application needs.

4 DESCRIPTION

4.1 BLOCK DIAGRAM AND MAIN ELEMENTS

Fig. 4.1-1 Block diagram

The SG Series 400 & 500 system can be divided into the following main elements:

Control System

SG Series 400 & 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 standard Rectifier consists of a 6-pulse SCR-bridge, which converts the 3-phase Utility Voltage into a controlled and regulated DC-voltage. This regulated DC-voltage is used to supply power to the Inverter, and to provide charging power to the Battery.

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 SG Series UPS's are equipped with an automatic system for the protection against voltage back feeding towards Utility, through the Bypass (Applied Standard IEC 62040-1). This protection works automatically by opening contactor K6 and eventually K7, and acts in case of internal defects of the system, or due to wrong manipulations on the Manual Bypass Q2 (option).

Manual Bypass (option)

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 accepted tolerances.

OPM_SGS_USM_M40_M50_2US_V010.doc User Manual SG Series 400 & 500 UL S2

4.2 OPERATION MODES

4.2.1 Normal operation mode

During normal operation, the Rectifier converts input AC power to DC. The DC power provides input power for the Inverter and charging power for the Battery. The Inverter converts the DC power to continuous and regulated AC power, which supplies the critical load. The control panel reports the Battery charge status and the expected backup time with the actual load.

Fig. 4.2.1-1 Block diagram normal operation mode

4.2.2 eBoost™ operation mode (option)

eBoost™

e high efficiency (up to 99%) Boost fast power transfer (< 4ms)

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.

Fig. 4.2.2-1 Energy flow in eBoost™ Operation Mode

When the Utility recovers, the Load returns to the Automatic Bypass after a variable time defined by the control unit.

The eBoost™ Operation Mode can be configured directly by the user for scheduled activation, 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 7.4

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 displays the estimated time the Battery can support the critical Load. Prior to the Battery completely discharging, the "stop operation" alarm (shutdown 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 parallel operation

With a parallel system for power capacity (see Section 4.3)

• With the Bypass Utility power available, a low Battery 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 low Battery 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 recharged enough 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 parallel operation

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 recharged enough 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.

OPM_SGS_USM_M40_M50_2US_V010.doc User Manual SG Series 400 & 500 UL S2

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 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.

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.

Fig. 4.2.5-1 Block diagram Automatic Bypass

In case of parallel operation

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.

4.2.6 Manual Bypass (option)

The Manual Bypass circuit consists of Q1 and Q2 manual switches, which permits transfer of the Load directly to the unconditioned AC power without interruption, leaving the UPS available for maintenance.

4.3 PARALLEL SYSTEM OPERATION

4.3.1 Introduction to the 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 SG Series 400 & 500 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+1

out of n redundant paralleled modules must be equal to or greater

than the required Load power. The Load will be equally shared by the n

units connected on the output bus.

Should one of the n

paralleled units trip Off-line, the remaining (n+1) 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 SG Series 400 & 500 Parallel System is designed to provide a complete Redundant Parallel Architecture, and is free from common equipment.

Not only the Inverters are redundant, but also the Bypass functions are designed with redundant modular concept.

When one UPS needs maintenance or service, the Load is powered by the other units supplying the Load bus.

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 it's own function and operational status and communicates with all other modules, in order to act or react if necessary, adapting it 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 later 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 inserted between the unit’s output and the Load common bus bars.

However, it is recommended that a disconnect or isolation switch be inserted.

4.4 RECTIFIERS PARALLELED ON THE SAME BATTERY

NOTE !

A parallel system with a Common Battery for two or more Rectifiers, requires a particular installation and adequate setting of some parameters, (accessible only through password), and can therefore only be done by a qualified engineer from GE.

Usually each Rectifier-Inverter Unit runs with its own Battery. In case of parallel units are running with a Common Battery (max. 4 UPS - see Fig 4.4-1), the sharing circuit between individual Rectifier 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 a special parameters setting, so they must be

prepared in advance before the installation.

• The installation must be performed only with the UPS system must be completely shut down.

• The AC Rectifiers input power (5) 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 / MCCB (7) on each line connecting the Rectifiers to the common

Battery for maintenance / safety reasons.

• In case one must be powered down for maintenance, switch-OFF the concerned unit before open

the DC fuses / MCCB on the Battery line (7).

• It is mandatory to connect an external NO free contact “Battery Fuses” to the UPS and to enable the

function by setting the parameter (see Section 4.1 of the “Installation Guide”).

• If an emergency generator set supply 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 having the Rectifiers on Common Battery.

• Do not connect the temperature sensor for automatic battery floating voltage compensation.

• Do not enable the function Boost charge (parameter 87).

Modem screen 1

Enabled

You can enable/disable with Y/N the remote control through modem calls by using this parameter. For modem connection, the default setting is for serial port J3 on Customer Interface.

Init

This parameter presents the modem initialization string. It can be 40 characters long.

When editing this parameter the UPS considers that a blank character terminates the string. If no blank character is found then all 40 characters are used.

Alarm call This Y/N parameter controls the automatic events signaling through modem. If this parameter is set to Y (Yes) the UPS itself will call the remote location when a new event occurs

Delay This parameter controls the delay between the occurrence of a new event and the modem dialing. It is useful because since the events typically do not occur isolated but in certain sequences, you can eliminate the need for multiple dial-outs for such a sequence of events.

Tel 1 This parameter specifies a first telephone number to be used for modem dial-out. The telephone number has a maximum 40 characters and cannot contain blanks. If the desired number is shorter than 40 characters, the string will finish with blanks.

Tel 1 enabled This parameter Y/N specifies if the first telephone number (Tel 1) will be used for dial-out.

PRINTER

Baud Rate : 2400 Parity : 0 Bits : 8 Handshake : XON

Printer setup screen

The UPS is capable of communicating to a serial printer, to printout disparate information. Please be sure to have a serial printer with a serial RS232 interface. This is the only printer-interface supported by the UPS.

Baud Rate

This parameter controls the baud rate used for data transmission.

Parity This parameter controls the parity used for data transmission.

Odd (O) even (E) and “No Parity” (NO) can be selected. In case “No Parity” (NO) has been set, automatically the parameter “8 bits“ is used, independently of the value of “Bits“ set.

Bits This parameter controls the length of the data word on the serial line during data transmission.

Handshake This parameter is used to determine the communication protocol used when printing.

Valid values are “XON” standing for the XON/XOFF protocol or “NO” standing for any protocol.

NOTE !

Please configure your printer with the following parameters: 2400/8/N (2400 bauds/sec, 8 bits, no parity).

Enabled (Y / N / Wait)

Y/N

This parameter (values Y/N) enables or disables the

eBoost™ Operation Mode. If the value is Y and the current time is in the interval for the current day, the eBoost™ Operation Mode is active.

Wait The eBoost™ Operation Mode configuration is being

updated.

In case of Parallel System

If eBoost™ Operation Mode is currently disabled (N) and Q1 is closed, when programming it to enable (Y) the selected configuration will automatically be propagated to all units in the 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 Operation Mode must be programmed during the week (the Y/N parameter is automatically disabled if this condition is not satisfied). In case this minimum time in VFI Operation Mode is not respected, the eBoost™ Operation Mode will be disabled.

If the value is N, the UPS is normally operating in VFI / double conversion mode at all times.

Status of the Home Page with UPS functioning in eBoost™ Operation Mode.

DAY OF WEEK (d1 ÷ d7): Enabling time in function of weekdays

Note: the configuration of the activation schedule can only be updated when eBoost™ Operation Mode is disabled (Enabled: N).

For the weekdays from d1 to d7 (Saturday to Friday) 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: eBoost START: The hour of the day after which the eBoost™ Operation Mode is enabled. The eBoost™ Operation Mode is enabled until the following eBoost STOP time is reached (the eBoost STOP time of the same day if this is later than the eBoost START time, the eBoost STOP time of the following day otherwise).

eBoost STOP: The hour of the day before which the eBoost™ Operation Mode is enabled. The eBoost™ Operation Mode is enabled starting from the preceding eBoost START time (the eBoost START time of

the same day if this is earlier than the eBoost STOP time, the eBoost START time of the previous day otherwise). Identical times for eBoost START and eBoost STOP maintain the existing mode only in case the previous command

was eBoost START and the following command will be eBoost STOP.

HOURS / DAY: The number of eBoost™ Operation Mode hours per weekday (from d1 - Saturday to d7 - Friday) is displayed in the operation mode parameter window (ceiling value).

To better understand the eBoost™ programming modes, some typical examples are shown:

Example 1:

For continuous eBoost™ Operation Mode set the eBoost START times to 00:00 and the eBoost STOP times to 23:59 for all weekdays, but almost 1 day must have 1 minute of VFI programmation: i.e d2 -

Sunday 00:00 to 23:58).

Example 2:

eBoost STOP before eBoost START. eBoost START 18:00, eBoost STOP 06:00 for weekday d4 - Tuesday. Means that on d4 - Tuesday the eBoost™ Operation Mode is active between 00:00 and 06:00 and between 18:00 and 23:59.

Weekday d1 - Saturday d2 - Sunday d3 - Monday d4 - Tuesday d5 - Wednesday d6 - Thursday d7 - Friday

Example 4:

If the eBoost™ Operation Mode must be enabled on Monday (d3) and Tuesday (d4) between 18:00 in the evening and 06:00 of the following morning, on Friday (d7) between 12:00 and 13:00, during all Saturday

(d1) and on Sunday (d2) until 20:00, the corresponding parameters are.

eBoost START

eBoost STOP

In dark color are displayed the times with eBoost™ Operation Mode. The arrows indicate the conditions given by the eBoost START and eBoost STOP times introduced with

the parameters. Note that on day d6 - Thursday the interval has length 0 (zero), therefore the eBoost™ Operation Mode

is not enabled on this day.

8 OPTIONS

8.1 COMMUNICATION 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 Power Diagnostics, GE Data Protection or GE Service Software), 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 Power Diagnostics

GE Power Diagnostics is an anytime, anywhere concept in UPS status monitoring and alarm notiﬁcation that has been successfully implemented in numerous of installations supporting up to multi-hundred UPS. Based on the leading Intelligent Remote Information System IRIS all GE UPS types as well as 3rd party UPS are supported. Accessing the latest site information via Web and being alerted by Email, SMS or Fax, it enables the user to make timely decisions in case of changing critical conditions. With comprehensive data collection and analysis IRIS is not only a remote monitoring & diagnostics (RM&D) system but, the core of the integrated service offering GE Power Diagnostics.

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 shutdown. An enhanced alarm management system provides the possibility to start applications, send messages, and send e-mails for every upcoming or disappearing alarm.

WARNING !

The installation and cabling of the options must be performed by Q U A LIFIED SERVICE PERSONNEL ONLY. Make sure that the UPS installation is completely powered down. Refer to the “Safety prescriptions - Installation” described on Section 1.

8.3.1 Remote Signaling Box (RSB)

The optional Remote Signaling Box allows monitoring of the operation of the UPS, using the potential free contacts fitted on the “P4 - Customer Interface Board“ of the UPS. It can be used by simply putting the box on a desktop or on a wall or, removing the box, it can be surface mounted.

The remote panel contains an internal buzzer and the following status indicators:

• Mimic diagram With LEDs indicating the operation of Rectifier and Inverter, and the power source supplying

the critical Load.

• Alarm Indicating a critical situation on the UPS (LED light and audible alarm).

• Stop Indicating the UPS is preparing to shut down in a short time.

• Mute Push button, resets the buzzer.

• Test Push button checks all the LEDs and the buzzer of the remote panel.

The cable connecting the RSB to the UPS cabinet must be min. 16 wires / 0.25mm2. The plug B is included in the delivery of the option RSB (cable connecting UPS with RSB not included). Maximal allowable length: 985 ft (300 m). It must be wired at one end with a D - female plug- 25 pin (J2 – P4 Customer Interface Board).

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 this test be 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.

9.1.5 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.

9.1.6 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).

9.1.7 Long shut-down periods of the UPS-system

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.
