Safety Precautions 1

1. SAFETY PRECAUTIONS

1.1 Dos 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 andother objects or walls.

The UPS must be well grounded to the buildings grounding system with a conductorthat has a current carrying capacity that matches the rating of the UPS.

If the unit contains an external battery cabinet, periodically check the groundingconnection between the external cabinet and the main UPS cabinet. (The batteryscabinet body must be connected with the grounding screw located on the electroniccabinet 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 attempt 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 Donts 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.

Do not connect or disconnect the cable to the battery cabinet before the battery circuitbreaker is turned off

Do not turn on the battery circuit breaker when the battery cabinet is disconnectedfrom the UPS.

General Features2

2. GENERAL FEATURES

The PS Series 3/1 Phase Uninterruptible Power Supply (UPS) employs Pulse Width Modulation(PWM) and is controlled by a high performance RISC1 micro-controller, to provide reliable,sophisticated protection for every type of line fluctuation, including interruption of the ac input .

Figure 1: Block diagram of the UPS's major components

Note: Maintenance bypass is available in models 20K and higher, or at customer request.

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, provides voltages of 3 380, 3 400, or 3 440V at a stabilized 50 or 60 Hz frequencydepending upon your configurationto any practicalload.

When backup service is provided (when the ac power mains fail), the UPS is powered bybatteries and maintains a constant output voltage supply. The system informs the operator, bymeans 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 powersurges, 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 communicationsport. 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:

1Reduced Instruction Set Computing

7/28/2019 _PS-SP

9/57



General Features 3

Electronic Cabinet that contains all electronic components: charger, inverter, staticswitch, 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 isshared 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 voltageis not interrupted even if one of units is faulty. If the parallel system is equipped with aGamatronic Static Switch unit, the output voltage is not interrupted even if more than one UPSunit is faulty.

The Gamatronic parallel UPS system contains the following features:

Each UPS is equipped with its own battery set

Each UPS can be equipped with an optional output choke

2.1 Parallel Operation

The PS Series 3/1 Phase UPS can accommodate parallel operation with either of two options,centralized or decentralized.

With a decentralized parallel system, each UPS has its own static switch in which case twosystems 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 thisconfiguration, two to ten UPS units may be connected in parallel.

2.2 Major SubsystemsThe device consists of the following modules:

2.2.1 Charger

The charger supplies a stabilized dc voltage to the device at 432 V 2 V.

2.2.2 Batteries

The batteries are always connected to the charger output and they supply voltage to the inverterduring power failures. During normal operation, the batteries are in standby mode. Batteries arehoused 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.

General Features4

2.2.4 Static Switch

In case the inverter can't supply the load with the correct voltage (i.e. because of overload, inrushcurrent on connecting the load, inverter malfunction, etc.), the ST.SW/Bypass automaticallytransfers the load from the inverter to the mains without voltage interruption or disturbance. Whenthe 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 outputvoltage returns to normal.

The inverter is synchronized with the mains in both frequency and phase to ensure correctoperation of the static switch. The static switch includes PC690/PC920 boards and RA101 -RA103 contactors.

2.2.5 Control System

The control system performs the following functions:

Tests input, bypass, inverter, battery voltage, output current, input/output signalfrequency, and temperature.

Controls the inverter and the bypass contactorRA101and manages the staticswitch and charger voltage during battery tests.

Controls the ALARM interface.

Reads the panel keyboard and sends messages to the front panel LCD display.

Communicates with devices via the RS232 interface.

The control system includes the PC801 control board, PC074/PC075 panel board, PC873 powersupply, current, and temperature sensors. Measured voltages and currents are connected to thecontrol board via the PC800 interface board.

2.3 Control PanelThe UPS is equipped with one of three models of control panels (PC074, PC075, or PC085). Thecontrol panel includes an LCD display screen and a touch pad control panel that enables the userto effectively manage the UPS. Once the UPS is installed, the control panel serves as the usersprimary interface with the system. Messages, warnings and error conditions are relayed to theuser through the control panels LCD display and through audible alarms.

See Figure 2, Figure 3, and Figure 4below.

General Features6

2.4 Power-on Self TestsThe 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 MeasurementThe user can receive real time information regarding the units operation and condition simply bypressing the appropriate status button. The real time results are displayed on the front panel.

2.6 Real TimeThe system includes a real time clock and calendar that sequentially manage the log file andprovide historical data to the user. This information is accessible via the LCD display or,optionally, through the RS232 communications port.

2.7 CommunicationsThe UPS relays all the measured data and events of the log file through an RS232communications port to a host computer or, using a modem connected to a telephone line, to aremote location, or via GMAC or GMACi, 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 duringoperation. This data is written to the log file and can be accessed easily at any time through thedisplay panel or computer (optional). This information is very useful for maintenance andanalyzing performance statistics.

2.9 Ease of UseThe UPS includes an on-line help feature that explains the systems features and describes eachof the LCD control buttons.

2.10 Battery CheckThe unit automatically and continuously checks the battery status and the battery cabinetconnection with the UPS.

2.11 Service ModeThe UPS has a technicians SERVICE MODE that is password protected. Access to the servicemode is only permitted after the technician successfully enters an assigned password.

General Features 7

2.12 ConnectionsFor 60 kVA: All connectionsconnection panel, input, output, and ST. Switchesare located onthe lower front of the UPS, behind the front door.

For 10-50 kVA: Switches and terminals are located on the UPS rear panel.

2.13 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 preventcirculation of energy between the UPS units and to isolate the faulty unit from the common powerbus. In addition, an active current sharing circuit changes the output voltage of each UPS toprovide proportional load sharing between the units.

One of the system's units takes on the function of Master. This unit is synchronized to the mainspower. The other units are Slaves and follow the Master. The function of Master is not dedicatedto one of the units. Any normally functioning UPS can be the Master.

2.13.1 Centralized vs. Decentralized Static Switch

The UPS employs a Static Switch for functional override. In parallel mode there are two possibleoptions 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 theload 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 theother UPS. To avoid such a hazard in decentralized mode, the Static Switches are synchronizedusing a special Gamatronic-supplied cable. Figure 6 on page 9 shows a cabling diagram forparallel decentralized operation of multiple UPSs.

For additional security, a second option is available as a centralized Static Switch. As illustratedin Figure 5 on page 8, in centralized parallel operation there is only one Static Switch (in aseparate housing) for the entire system. Local static switches are inhibited. This methodsignificantly increases system reliability, because the output voltage is constant even if bothUPSs are disconnected. Up to ten units can be connected in parallel.

2.13.2 Decentralized Parallel Mode of OperationThe PS SP UPS uses a simple master/slave hierarchy, where one unit at any given time isdesignated 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, andtransmits the phase and frequency information to the Slave UPSs, which synchronize themselvesaccordingly.

When the Master UPS fails, the next UPS in line becomes the Master, and is now responsible fortransmitting phase and frequency information to the Slave UPSs.
