GENERAL DESCRIPTION

1.1 Introduction

EL-300 series Emergency lighting inverter, are being manufactured with the state-of-the art PWM and IGBTtechnology, produce microprocessor controlled pure sine wave output to critical loads. EL-300 seriesinverterss install between the critical load and the mains.

The advantages of using Inverter:

Power blackout protection:If the mains power fails, the EL-INVERTER continues to power the critical load from its battery source,leaving the load immune from power disturbances.

Increased power quality:The EL-INVERTER has its own internal voltage and frequency regulator circuits, which ensure that itsoutput is maintained within close tolerances when supplying the load.

Features :

Pure sine waveoutput.

PWM and IGBT technology.

2 Microprocessors in each EL-INVERTER

Microprocessor controlled main controller board.

Microprocessor controlled rectifier board.

Static (STS) and maintenance by-pass.

LCD (Liquid Crystal Display) display.

Alarm history (Memory for max. 64 alarms.)

High quality maintenance-free lead-acid type batteries.

High nonlinear load capacity, special for computers.

Automatic and Manual Battery Test System:

After all the pre conditions ensured, the battery test is made periodically by itself.

Nonlinear loads driving capability

Facility of connection with the PC:

In case of failure, alarms of the Inverter (Battery low, mains control or general) is shown by the dry relaycontacts and RS232, to the user. The relay interfaces are specially produced for the server systems (IBMAS400 and Microsoft Windows NT).

Accessories:o Optional Inverter monitoring software ( RUPS, RUPSII, UPSILON) SNMP devices, compatible

to any operating system.oRemote Monitoring Panel (RMP) available: You can observe the EL-INVERTER status and parameters

1.2 Design Concept

S1 : Inverter input power switch

S2 : Static by-pass input power switch

S3 : Maintenance by-pass power switch

S4 : Output switch

S5 : Battery circuit breaker (optional)

RECTIFIER:The first conversion stage (from AC to DC) uses a 3 phase, fully controlled rectifier to convertthe incoming mains supply into a regulated DC BUS BAR. The DC BUS BAR produced by the rectifierprovides both battery charging power and power to the inverter section.

BATTERY GROUP:It keeps as an reserve DC power supply, for the inverter in case of mains failure.

INVERTER: It is made by utilizing the latest technology of power transistor (IGBT) and pulse widthmodulation (PWM). Inverter converts dc bus voltage into (second conversion) an alternative voltage like linevoltage. And provides this voltage and frequency being fixed.

STATIC TRANSFER SWITCH (STATIC BY-PASS): The static transfer switch of the unit contains anelectronically controlled switching circuit, which enables the critical load to be connected either to inverteroutput or to utility power source via the static by-pass line.The load is switched between the utility supply and the inverter output depending on the operation mode endavailability of the power source.

MECHANIC TRANSFER SWITCH (MAINTENANCE BY-PASS): A second, manually controlled,maintenance by-pass supply is also incorporated into the EL-INVERTER. Its purpose is to enable the criticalload to be powered from the mains (by-pass) supply while the unit is shut down for maintenance ortroubleshooting purposes.The load is unprotected against mains power supply disturbances or failure when itis connected to the maintenance by-pass supply.

BATTERY CIRCUIT BREAKER:There is a fuse loadbreak switch (externally mounted) between the Inverterand the batteries. The battery is connected to the DC BUS BAR through a fuse link. This circuit breaker isclosed manually.

BATTERY GROUP (CABINET): The batteries associated with the Inverter are generally housed in apurpose-built cabinet located along-side the main Inverter equipment. For a long-term efficiency from the

batteries, keep them in room temperature (20C).

1.2.1 The Operating Modes of the Emergency lighting nverter

A. CHANGEOVER MODE: All relevant power isolators and circuit breakers are closed (exceptmechanical transfer switch). The load is powered from the incoming utility supply. At the sametime the battery charging is performed. In case of a utility power supply failure, the load istransferred to inverter output without interruption. During this operation the inverter converts DCpower (from batteries) to AC power. Critical loads are supplied until the batteries are fullydischarged. At the end of the discharge time, the unit first gives A7 BATTERY LOW alarm. Ifthe batteries are fully discharged, it A5 BAT. AUT END message and shutdown. When themains is restored, the EL-Inverter returns back to normal operation (changeover mode)

B. INVERTER MODE: All relevant power isolators and circuit breakers are closed. (exceptmechanical transfer switch) The load is powered from the well regulated nverter output with

stable voltage and frequency. Rectifier stage supplies both the inverter and performs batterycharging at the same time.In case of a utility power supply failure, the load is still supplied by the inverter which uses theDC power from the batteries this time, to produce AC power.

C. MAINTENANCE BYPASS: In this mode, the EL-Inverter is shutdown, and the load is supplieddirectly by the mains through the maintenance bypass switch.

III. OPERATING INSTRUCTIONS

3.1 Introduction

The operating intructions will be considered in two parts :1- CHANGEOVER MODE2- INVERTER MODE

3.1.1 OPERATION INSTRUCTIONS FOR CHANGEOVER MODE

1- Make sure that all the switches and fuses (S1,S2,S3,S4 and S5) are in off position.

Note : It is useful to connect an external battery circuit breaker in series with S5, since thebatteries should only be connected following the rectifier start up. Otherwise excessivecapacitor charging current may flow through the battery links.

2- Turn on S2 switch (static bypass) into 1 (ON) position.

3- Turn on the S1 switch (inverter input), into 1 possition. By turning on S1, all lights on the frontpanel will be lit for abaout 4 seconds (lamp test) and then, the following messages will appear onLCD.

RECTIFIER START : Rectifier is operating and static bypass input (utility supply)supplying the output.

INVERTER START : Inverter starts operating and static bypass input continues tosupply the output.

STATUS NORMAL : Normal operation of the supply, the output is still supplied bythe bypass input if the unit is in the CHANGEOVER Mode.

The load is supplied by the inverter if the unit is in INVERTERMode.

Note :Make sure that Changeover Mode has been selected in the settings menu.

4- Turn on S5 (and/or the external battery circuit breaker, if exsits) by inserting the battery fuse link.Now the backup battery bank is connected to the unit.

5- Turn on S4 (output switch) to supply the loads connected to the output of the unit.

3.2 OPERATION AND TEST OPTIONS OF THE UNIT IN THE CHANGEOVER MODE IN ANEMERGENCY LIGHTING SYSTEM

1) UTILITY SUPPLY FAILURE : If the Inverter is in CHANGEOVER MODE the output is supplied by

incoming utility supply. In case of a failure in this supply, the output is connected to the static inverteroutput. This transfer operation is performed internally by the control logic of the Inverter.

2) An external phase failure device, via external phase fail terminals (Terminals 3 and 4 on the ELC02Board ) can also be used to externally monitor a phase which is not supplying the machine. Terminals 3and 4 should normally be kept shorted under normal operating conditions. When the external phasefailure device opens these terminals, the output is switched to inverter.

3) A N/C momentary test button can be connected across the terminals 5 and 6 on the ELC02 board,providing an immediate test that the system is working OK by forcing the load on to the inverter and de-energizing the none-maintained contactor if fitted. (The NC contacts of the contactor should be used forconnecting the load to the Inverter outputs.) The operation of the extrenal test switch is indicated on theLCD with A17 TEST EXT. Message.

4) Terminals 7 and 8 on the ELC02 Board are for connection to an external switch so the end user cancontrol the output of the system (i.e. the lights are on or off) if a NC none-maintained contactor is used inseries with the Inverter output. For maintained operation this switch (connected across 7 and 8 ) shouldbe open and for non-maintained operation it should be closed. The none maintained contactormentioned above should have a coil voltage of 24V DC, and this voltage is available across theterminals 9 and 10 on the ELC02 Board (max 3 Amps). Even if this switch is closed for non-maintained operation, the non-maintained contactor is deenergized and the lights are turned onin case of power failure.

5) A fire Alarm Relay (FAR), with a 24V DC coil is mounted on the ELC02 board and its coil is connectedvia terminals 1 and 2, to the 24V DC control output of the remote Fire Alarm Panel. Under normaloperating conditions this relay is energized and if the external 24V DC supply to terminals 1 and 2 is lost(in case of a fire alarm) the FAR will be de-energized by forcing the load on to the inverter and de-energizing the none-maintained contactor, regardless of the position of the switch connected accrossterminals 7 and 8. That means under fire alarm conditions the load is turned on, anyway. FAR can bekept energized, for test purposes by inserting jumpers J3(-) and J4 (+) on the ELC02 board.

6) There are also two more test options (TEST1 and TEST2) which can be performed using the buttons on

the LCD panel.

a) TEST1 :- Choose and enter the COMMAND menu on the LCD panel.-Choose ENTER TEST1 and press ENTER button. In this case the load is transferred to inverter

and the Inverter stays in this position for a fixed period of time (Approx. 8 seconds) and thentransferred back to utility supply (normal changeover mode) Each time the ENTER button ispressed this test is repeated.

b) TEST2 :-Choose ENTER TEST2 in the COMMAND Menu,-And press the ENTER Button.

In this case, a line failure is simulated for test purposes (autonomy test). In other words the rectifier is turned

off and the load is transferred to inverter, with batteries supplying the system. This test will go on until youpress the ENTER button again, when you seeENTER TEST END on the first line of LCD. This process isindicated on the panel by A20 TEST2. Test 2 is reset aoutomatically if a BAT AUT END (Battery automy end)alarm is produced.

3.2.1 OPERATING INSTRUCTIONS FOR INVERTER MODE

Follow the same procedure given in section 3.1.1, only make sure that the INVERTER Mode hasbeen selected in settings menu.

MODE SELECTION :

Using the UP-DOWN buttons on the front panel, select SETTINGS MENU on LCD and pressENTER When you see MODE display select either CHANGEOVER or INVERTER modeusing (+) and (-) buttons.

After selecting the desired operation mode, press ENTER untill you hear the beep sound.

4.4.3 Battery Installation

ATTENTION!!! Remove the battery fuse before making the connection of the battery circuit breaker boxduring the battery installation.

The batteries associated with the EL-INVERTER equipment are usually contained in a purpose-built batterycabinet, which sits alongside the main equipment. Sealed, maintenance-free batteries are normally used inthis type of installations.

Where battery racks are used, they should be sited and assembled in accordance with the batterymanufacturers recommendations. In general, batteries require a well-ventilated, clean and dry environmentat reasonable temperatures to obtain efficient battery operation.

In general a minimum space of 10 mm must be left on all vertical sides of the battery block. A minimumclearance of 20 mm should be allowed between the cell surface and any walls. A clearance of minimum150mm should be allowed between the top of the cells and the underside of the shelf above (this is necessary formonitoring and servicing the cells). All metal racks and cabinets must be earthed. All live cell connectionsmust be shrouded.

The batteries are connected to the Inverter through a circuit breaker (optional), which is manually closed. If

the batteries are cabinet-mounted this circuit breaker is fitted within the cabinet; however, if the batteries arerack-mounted or otherwise located remote to the main Inverter cabinet then the battery circuit breaker mustbe mounted as near as possible to the batteries themselves, and the power and control cables connected tothe Inverter using the most direct route possible.

1. Unpack each battery and check its terminal voltage. If any battery has terminal voltage less than 10,5 V itmust be charged before continuing.

2. Please check the battery connecting hardware.

3. Start locating the batteries from top to the bottom on the racks.
