Safety Precautions 1

1. SAFETY PRECAUTIONS

1.1 Do’s

• Read this manual carefully before operating the UPS.

• Review the safety precautions described below to avoid damaging

users or equipment.

• Install the UPS in a clean and well-ventilated location.

• Leave at least 20 cm of clearance space between the ventilation holes

of the UPS and other objects or walls.

• The UPS must be well grounded to the building’s grounding system

with a conductor that has a current carrying capacity that matches the

rating of the UPS.

• If the unit contains an external battery cabinet, periodically check the

grounding connection between the external cabinet and the main UPS

cabinet. (The battery’s cabinet body must be connected with the

grounding screw located on the electronic cabinet or directly to the

grounding circuit.)

• Use the UPS only for its intended purpose.

• Allow only qualified technicians to service the UPS. There are no user-

serviceable components. Do not try to repair it yourself!

WARNING

Appropriate precautions should be taken during inspection and servicing; there

is a risk of lethal electric shock. The battery cabinet contains 12-Volt batteries

that provide high voltage even when the UPS is not connected to the mains.

1.2 Don’ts

• Do not open the cover under any circumstances.

• Do not insert any objects through the ventilation holes.

• Do not put objects on the UPS.

• Do not move the UPS while it is operating.

• Do not turn the UPS upside down during transportation.

General Features 2

2. GENERAL FEATURES

The

PS Series 3/3 Phase Uninterruptible Power Supply (UPS) employs Pulse Width

Modulation (PWM) and is controlled by a high performance RISC

micro-controller,

to provide reliable, sophisticated protection for every type of line fluctuation,

including interruption of the AC input .

Figure 1: Schematic Diagram of the Operation of the UPS

In the event of a power failure, the UPS provides backup power for a specific period

of time.

The system is user friendly. Its operation is simple and requires no previous technical

knowledge. The UPS operates on-line and once activated, the unit provides a voltage

of 3 × 208VAC at a stabilized 60 Hz frequency to any practical load.

When backup service is provided (when there is a power breakdown in the mains), the

UPS is powered by batteries and maintains a constant output voltage supply. The

system informs the operator, by means of LED indicators and audible signals, when a

power failure occurs.

The UPS is equipped with a Static Switch that enables the load(s) device(s) to

continue normal operation when the inverter is unable to supply exceptionally heavy

loads, such as during power surges, or in case of inverter failure, for any reason.

An LCD display on the UPS front panel provides real time, current operational status

of the UPS, providing the user with complete up-to-date information.

Similar status information may be viewed on a computer monitor via an RS232

communications port. The system can also be connected to the service center via a

modem and a telephone line, or to a computer network via an SNMP/WEB agent.

The unit consists of two major subsystems:

Reduced Instruction Set Computing

Gamatronic Electronic Industries Ltd. User Guide

µPS-SP 3:3, 3x220 in, 3x208 60 Hz out

General Features

• Electronic Cabinet that contains all electronic components: charger,

inverter, static switch, microprocessor board, panel, etc.

• Battery Cabinets that contain batteries and circuit breaker.

The unit can operate in parallel with similar Gamatronic UPS units. In this case, the

load is shared between the units. The parallel UPS system is the most reliable energy

source for any critical load. If the system uses N+1 UPS units (the redundant parallel

system), the output voltage is not interrupted even if one of units is faulty. If the

parallel system is equipped with a Gamatronic Static Switch unit, the output voltage is

not interrupted even if more than one UPS unit is faulty.

2.1 Parallel Operation

The

PS-SP UPS can be operated in parallel with similar UPSs. Up to 10 units can be

connected in parallel to feed and backup the same load. Two topologies are

supported: centralized and decentralized.

With a decentralized parallel system, each UPS has its own static switch in which

case two systems can be connected in parallel, to provide full redundancy.

With a centralized parallel system, the static switch is external instead of inside each

UPS. In this configuration, two to ten UPS units may be connected in parallel. See

“Parallel Operation” beginning on page 8.

2.1.1 Advantages of Parallel Operation

Redundancy

Parallel operation of the UPS provides redundancy in the event of a UPS failure.

Parallel operation is appropriate where the devices supported by the UPS are of

critical importance and higher MTBF is required.

Load Sharing

The

PS SP UPS includes a high-speed microcontroller to manage the process of load

sharing between the units connected in parallel. The microcontroller also ensures

synchronization of the phase and frequency of the output of all of the UPSs.

2.2 Major Subsystems

The

PS SP UPS consists of the following modules:

2.2.1 Rectifier

The rectifier supplies a stabilized DC voltage to the device at 216V ± 2V.

User Guide Gamatronic Electronic Industries Ltd.

µPS-SP 3:3, 3x220 in, 3x208 60 Hz out

General Features 4

2.2.2 Batteries

The batteries are always connected to the rectifier output and they supply voltage to

the inverter during power failures. During normal operation, the batteries are in

standby mode. The batteries for all models are housed in separate battery cabinets.

2.2.3 Inverter

The inverter receives a DC voltage from the charger or batteries and supplies a

regulated, frequency-stabilized, AC voltage (power). The inverter incorporates an

IGBT transistorized bridge, driver, (PC968 board), an L-C filter circuit, isolated

output transformer circuit, current transformer, PC906 board, and a PC801 control

board.

2.2.4 Static Switch

In case the inverter cannot supply the load with the correct voltage (for example:

because of overload, inrush current on connecting the load, inverter malfunction,

etc.), the ST.SW/Bypass automatically transfers the load from the inverter to the

mains without voltage interruption or disturbance. When the UPS is in BYPASS

mode, the load draws power directly from the mains, bypassing the inverter. The

ST.SW automatically switches the load back to the inverter when inverter's output

voltage returns to normal.

The inverter is synchronized with the mains in both frequency and phase to ensure

correct operation of the static switch. The static switch includes the PC690 board and

the RA101 - RA103 contactors.

2.2.5 Bypass Isolation Transformer (option)

For customers requesting this option, the UPS includes an isolation transformer

connected to the Bypass AC input. The function of this transformer, together with the

Inverter isolation transformer, is to create a condition of complete galvanic isolation

between the input and output of the UPS.

2.2.6 Control System

The control system performs the following functions:

• Tests input, bypass, inverter, battery voltage, output current,

input/output signal frequency, and temperature.

• Controls the inverter and the bypass changeover contactor—RA101—

and manages the static switch and charger voltage during battery tests.

• Controls the Alarm interface.

• Reads the panel keyboard and sends messages to the front panel LCD

display.

Gamatronic Electronic Industries Ltd. User Guide

µPS-SP 3:3, 3x220 in, 3x208 60 Hz out

General Features

• Communicates with devices via the RS232 interface.

The control system includes the PC801 control board, PC075/PC085 panel board,

PC873 power supply, current, and temperature sensors. Measured voltages and

currents are connected to the control board via the PC800 interface board.

2.3 Control Panel

The UPS is equipped with an LCD display and touch pad control panel that enables

the user to effectively manage the UPS. Once the UPS is installed, the control panel

serves as the user’s primary interface with the system. Messages, warnings and error

conditions are relayed to the user through the control panel’s LCD display and

through audible alarms.

µPS-SP 3:3, 3x220 in, 3x208 60 Hz out

General Features 6

2.4 Power-on Self Tests

The UPS automatically performs the following series of diagnostic tests when

initially powered on:

• LED test. All LEDs are lit individually for the operator to monitor.

• Real-time clock

• EEPROM. Memory (setup, calibration and events log) is tested.

2.5 Measurement

The user can receive real time information regarding the unit’s operation and

condition simply by pressing the appropriate status button. The real time results are

displayed on the front panel.

2.6 Real Time

The system includes a real time clock and calendar that sequentially manage the log

file and provide historical data to the user. This information is accessible via the LCD

display or, optionally, through the RS232 communications port.

2.7 Communications

The UPS relays all the measured data and events of the log file through an RS232

communications port to a host computer or, using a modem connected to a telephone

line, to a remote location, or via GM

C or GM

Ci, proprietary SNMP agents, for

network access.

2.8 Event Logs

The system compiles a listing of up to 256 extraordinary events of the mains, unit and

load during operation. This data is written to the log file and can be accessed easily at

any time through the display panel or computer (optional). This information is very

useful for maintenance and analyzing performance statistics.

2.9 Ease of Use

The UPS includes an on-line help feature that explains the system’s features and

describes each of the LCD control buttons.

2.10 Battery Check

The unit automatically and continuously checks the battery status and the battery

cabinet connection with the UPS.

Gamatronic Electronic Industries Ltd. User Guide

µPS-SP 3:3, 3x220 in, 3x208 60 Hz out

General Features

2.11 Service Mode

The UPS has a technician’s SERVICE MODE that is password protected. Access to

the service mode is only permitted after the technician successfully enters an assigned

password.

2.12 Emergency Power-Off (EPO)

The system includes a pair of wires linking two Emergency Power-Off terminals,

located together with the other terminals. These terminals are labeled “EMERG.

OFF” or “EPO (N.C.)”

The Emergency Power-Off terminals should be connected by a normally closed, 48V

0.1A mushroom-type pushbutton.

Pressing the pushbutton opens the contact and shuts down the unit. Power to the load

is cut. See also section 5.5, “After Use of the Emergency Power-Off Switch” on page

33.

2.13 Connections

For the 30-60 kVA models: All connections—connection panel, input, output, and

batteries—are accessed via the lower portion of the front of the UPS. The user must

unlock the door with a flathead screwdriver to access these areas.

For the 10-20 kVA models: All connections are made on the rear panel of the UPS.

User Guide Gamatronic Electronic Industries Ltd.

µPS-SP 3:3, 3x220 in, 3x208 60 Hz out

Parallel Operation (option) 8

3. PARALLEL OPERATION (OPTION)

Each UPS can optionally operate in parallel with similar units as part of a modular

UPS system. Up to ten units can be connected in parallel.

Special technical solutions are used to synchronize all the units of the system, to

prevent circulation of energy between the UPS units and to isolate the faulty unit from

the common power bus. In addition, an active current sharing circuit changes the

output voltage of each UPS to provide proportional load sharing between the units.

One of the system's units takes on the function of Master. This unit is synchronized to

the mains power. The other units are Slaves and follow the Master. The function of

Master is not dedicated to one of the units. Any normally functioning UPS can be the

Master.

3.1.1 Centralized vs. Decentralized Static Switch

The UPS employs a Static Switch for functional override. In parallel mode there are

two possible options of Static Switch operation, centralized and decentralized.

In decentralized mode each UPS includes its own Static Switch which works

independently. However, if one UPS were to fail, the Static Switch would instantly be

triggered and supply the load directly from the mains. Two or more units would then

be connected in parallel. This would connect the inverter of the other UPS directly to

the mains which could potentially damage the other UPS. Therefore, to avoid such a

hazard in decentralized mode, the Static Switches are synchronized using a 3-wire

cable. Figure 4 on page 9 shows a cabling diagram for parallel decentralized operation

of multiple UPSs.

For additional security, a second option is available as a centralized Static Switch. As

illustrated in Figure 5 on page 10, in centralized parallel operatoin there is only one

Static Switch (in a separate housing) for the entire system. Local static switches are

inhibited.This m

ethod significanly increases system reliability, because the output

voltage is constant even if both UPSs are disconnected. Up to ten units can be

connected in parallel.

3.1.2 Decentralized Parallel Mode of Operation

The

PS SP UPS uses a simple “master/slave” hierarchy, where one unit at any given

time is designated as the Master UPS and the remaining parallel units are considered

Slave UPSs.

The Master unit synchronizes its output voltage with the bypass phase and frequency,

and transmits the phase and frequency information to the Slave UPSs, which

synchronize themselves accordingly.

When the Master UPS fails, the next UPS in line becomes the Master, and is now

responsible for transmitting phase and frequency information to the Slave UPSs.

Control Panel & Indicators

4. CONTROL PANEL & INDICATORS

The control panel serves as an interface between the UPS and the user. Real time

information is displayed visually and audibly. Textual information is presented on the

LCD display. These messages are often reinforced with audible alerts to alert the user

of extraordinary circumstances.

Because the control panel of the standard cabinet (used for the 10-60KVA models)

differs in appearance from the console of the larger cabinet (an option for the 40-60

kVA models), we discuss two control panels separately, according to cabinet type.

The description of the standard 10-60 kVA control panel begins in section 4.1 on this

page; the control panel on the larger cabinet (option for 40-60 kVA models) is

described beginning in section 4.2 on page 16.

4.1 The Control Panel on the Standard Cabinet

The control panel has 6 round function buttons for controlling the unit and 12 square

information buttons for reporting the status of the UPS.
