provides for the safe installation, startup and use of the EDP70 PLUS Uninterruptible Power System (UPS). The Company recommends that the equipment be installed and regularly maintained by a Chloride Authorized personnel. DO: - DO NOT: 1.2 read the User Handbook before operating the EDP70 PLUS UPS. keep a log of all incidents. protect the batteries from damage. Batteries leak acid; avoid contact with skin, clothes or eyes. - operate the control switches. - operate the EDP70 PLUS UPS with any covers removed. - obstruct the ventilation grilles. Summary of the equipment The EDP70 PLUS Uninterruptible Power System (UPS) totally isolates the load from voltage drops, spikes, transients frequency variations in the utility supply. In the event of failure or brownout of the AC utility supply, an internal audible alarm sounds and an LED on the control panel illuminates, the EDP70 PLUS UPS will continue to provide safe, clean continuous power, without interruption, from the battery, for a duration dependent on battery capacity and output load. The audible alarm alerts the user to start a safe orderly shutdown of the load. When the AC utility supply returns to normal, the EDP70 PLUS UPS automatically recharges the battery ready for any future power failure. The microprocessor display panel provides access to very detailed information regarding the status of the supplies and EDP70 PLUS UPS. Refer to current publication for detailed specification. The block diagram, shows the main functional sub-assemblies of the EDP70 PLUS UPS. The AC three phase utility supply is rectified to provide direct current, which maintains the battery in a fully charged state and also supplies the inverter, which provides the three phase output via an electronic static switch. Normally the supply of the reserve line is taken from the AC utility input, but special units, with a separate reserve input supply, are available. This allows the inputs to be supplied from independent three phase sources. Provided the reserve supply is within limits, the inverter will match the output frequency with the reserve supply frequency. The inverter has its own internal crystal control to stabilize the output frequency if the reserve supply frequency is out of limits. The electronic static switch switches the output from the inverter to the reserve supply, without interruption, to meet any load current surges, or to supply the load if the battery is discharged during an AC utility supply failure. Maintenance and testing can be carried out on the EDP70 PLUS UPS without interrupting the output, by switching the load from the reserve supply to the maintenance bypass circuit. This work should only be carried out by Chloride-trained personnel. 1.3 Block diagram page 6 -- MI00/10056 rev.1--05/2001 24kVA - STANDARD CONFIGURATION S3 S2 Reserve Supply 208Y/120V Maintenance By-pass 3 S1 5 290 150 AC Supply S4 208 4 1 Battery Contactor IN THE ABSENCE OF A SEPARATE RESERVE SUPPLY THE RESRVE IS DERIVED FROM THE AC UTILITY INPUT WITH THE JUMPER CONNECTED AS INDICATED 2 144 Cells (Internal) 36kVA - STANDARD CONFIGURATION S3 Maintenance By-pass S2 Reserve Supply 208Y 208Y 250 480 AC Supply 5 3 S1 S4 208Y 4 1 Battery Contactor IN THE ABSENCE OF A SEPARATE RESERVE SUPPLY THE RESRVE IS DERIVED FROM THE AC UTILITY INPUT WITH THE JUMPER CONNECTED AS INDICATED 240 Cells (External) 2 36kVA - 480V/208V CONFIGURATION S3 Maintenance By-pass S2 Reserve Supply 208Y 480V AC Supply 5 3 S1 250 480 4 1 IN THE ABSENCE OF A SEPARATE RESERVE SUPPLY THE RESRVE IS DERIVED FROM THE AC UTILITY INPUT WITH THE JUMPER CONNECTED AS INDICATED S4 208Y Battery Contactor 240 Cells (External) 2 Figure 1 – Block diagrams – 24/36kVA MI00/10056 rev.1--05/2001-- page 7 S3 Reserve Supply Maintenance Bypass S5 S2 480V 480Y/277V 5 3 S4 S1 208Y/120V AC Supply 1 4 Battery Contactor IN THE ABSENCE OF A SEPARATE RESERVE SUPPLY THE RESERVE IS DERIVED FROM THE AC UTILITY INPUT WITH THE JUMPER CONNECTED AS INDICATED 240 Cells (External) 2 Figure 2 – Block diagram – 50/80kVA The uninterruptible power system consists of the following: 1 2 3 4 5 1.4 - RECTIFIER/INVERTER BATTERY BACKFEED PROTECTION INVERTER STATIC SWITCH RESERVE STATIC SWITCH S1 = Equipment ON/OFF switch S2 = Equipment Reserve switch S3 = Equipment By-pass switch S4 = Equipment OUTPUT switch (INVERTER OUTPUT switch for 50/80kVA only) S5 = RESERVE OUTPUT switch for 50/80kVA only Functions RECTIFIER / BATTERY CHARGER The rectifier/battery charger transforms the alternating current of the mains supply to direct voltage to maintain the battery in a fully charged state and also supply the inverter. BATTERY The battery is an energy reserve that is used by the inverter and the load whenever the mains supply fails. INVERTER The inverter changes the direct voltage from the rectifier or from the battery into a three phase sinusoidal alternating voltage for the external supply. ELECTRONIC STATIC SWITCH The function of the electronic static switch is to select one of the two sources of alternating voltage and to supply it to the external load. The two sources of voltage supplied to the static switch are the output of the inverter and the reserve supply. In normal working conditions, the static switch supplies the load from the inverter. SWITCHES The switches permits maintenance and repair of the UPS, without interrupting the supply to the load. page 8 -- MI00/10056 rev.1--05/2001 1.5 Operational modes S3 Maintenance By-pass S2 S1 LOAD AC Supply S4 Battery Contactor 24/36kVA Ratings S3 Maintenance By-pass S2 S5 480Y/277V LOAD S4 S1 208Y/120V AC Supply Battery Contactor 50/80kVA Ratings Figure 3 – Normal operation During normal operation the load is supplied by the mains through the rectifier and inverter.

This will be indicated on the UPS front panel display and the Remote Alarm Unit (if fitted). The standby time available depends both on the capacity of the battery and on the size of load. It is possible to extend autonomy by reducing the output power by disconnecting non-important loads. In all cases, the alphanumerical display shows the residual autonomy.

If the overload is temporary, the system will re-transfer from reserve to inverter as soon as the it ceases. This allows for the initial start-up of loads with high or excessive switch-on currents. page 10 -- MI00/10056 rev.1--05/2001 2.0 SAFETY Read all instructions carefully before installing or operating the equipment. 2.1 General safety The procedure described in these instructions is intended for use by persons experienced in the operation of Uninterruptible Power Systems and ancillary equipment.

The heat, dissipated by the UPS (indicated on figure 7), is extracted by internal fans and then dissipated into the air. The heat can be removed from the UPS room by a forced cooling ventilation system or, alternatively, an air conditioning system. The required air changes per hour will depend on the UPS rating and this heat loss and on the cooling air temperature. To calculate the required air flow for the dissipated power, the altitude and the cooling air temperature, the following equation can be used: • Pd V = 2770 - - - - - - • e (0.125 h Tk / T0 ) Tr - Tk with: V = Pd Tr air flow [mc/h] = total dissipated power [kW] = max. temperature allowed into the room [104°F = 40°C = 313°K] Tk T0 = Temperature of input cooling air = 273 °K h = altitude above the sea level [km] page 24 -- MI00/10056 rev.1--05/2001 5.0 CONNECTION Protection devices to be installed by the customer according to the information shown on page 23 L1 UTILITY L2 INPUT L3 N A B C N A B C N Neutral not present on 50 and 80kVA ratings L1 L2 OUTPUT L3 N (Neutral separately derived on 50 and 80kVA ratings) EXTERNAL BATTERIES 1 2 3 4 5 6 G Remove link to connect remote E.P.O.

This allows a remote E.P.O. to be installed, in series with the standard one installed inside the UPS. (See Para. 9.1) Warning: To avoid unauthorized stopping, it is strongly recommended that some form of security switch be used.. b) Battery charge inhibited By removing the link between terminals 3 and 4, the battery charge will be inhibited, and a warning message will be displayed. Possible uses of this could be one, or more, of the following: • connect the above terminals to a contact which will be opened if there is Hydrogen within the battery compartment(s). In this way the cause of hydrogen generation will be stopped, and a warning about the operating status of the system will be displayed. • connect the above terminals to a contact which will be opened when the UPS is supplied by a Generator (it should be an auxiliary contact of the Line <-> Generator changeover). In this way it will be possible to limit the power supplied by the Generator to the only value required to supply the critical loads, and not to charge the battery until the mains supply returns. In this way it is possible to use a Generator having a power rating less than the maximum input power of the UPS. Also in this case a warning about the operating status of the system will be displayed. c) Thermostick connector (50/80kVA only) This connection provides the customer with remote control over the output transformer Overtemperature Alarm (TCORE = 180°C). NOTE: If more than one of the above applications (or similar) are installed, the contacts MUST be connected in series. page 38 -- MI00/10056 rev.1--05/2001 6.0 CONTROLS 6.1 User Controls The user controls are situated on the front panel, see Figure 25.

If a unit requires servicing, the Manual Maintenance Bypass allows the load to be connected directly to the AC supply so that the unit may be serviced in safety. The following instructions must be followed: 1. Ensure that ‘SYSTEM NORMAL’ is displayed on the LCD. (Note: If ‘SYSTEM NORMAL’ is not displayed check that the inverter is not ‘OUT OF SYNC’, see section 10.7. Turning the inverter off under this fault condition will interrupt the load supply.) 2. Turn off the inverter by pressing the inverter shutdown button for more than 2 seconds 3. Turn the Maintenance Bypass Switch (located behind front panel, see figure 14, 17 or 20) to ON. 4. Turn off the Primary Input, Reserve Input and UPS Output Switches, see figure 14, 17 or 20. THE LOAD IS NOW SUPPLIED DIRECTLY FROM THE AC UTILITY SUPPLY AND IS NO LONGER PROTECTED BY THE UPS CAUTION: Some components in the UPS will retain a static voltage even after the switches have been opened. Also, on the 50/80kVA ratings, the isolating transformer and the relative cooling fans are still supplied from the Bypass. To return to the normal operating mode, follow the above procedure in reverse. Note: 9.0 The EDP70 PLUS UPS must not be left operating with the Maintenance Bypass Switch in the ON position. SHUT-DOWN 1. Close down the load in an orderly manner. 2. Push the (inverter shutdown) button for more than 2 seconds. 3. Turn the main switch to OFF. Note: If the electricity supply to the site is switched off outside normal working hours, the EDP70 PLUS should be shut down each evening, by either using the shutdown procedure or wiring in the Emergency Power Off (EPO) function, see figures 14, 17, 19 or 22 (depending on the UPS size). This will prevent the battery from discharging. If, on the other hand, the supply to the site is continuous, the EDP70 PLUS should be operated 24 hours a day. 9.1 Installing the EPO To wire the EPO, open the link between terminal boards 1 and 2 and connect a signal switch: when the switch is enabled, the inverter and rectifier will stop, the battery relay will be opened and the load will be de-energized page 42 -- MI00/10056 rev.1--05/2001 To ensure that the EPO functions correctly, the signal should remain active for a period > 400 msec.

If any Switches are not turned to OFF the equipment and battery may be damaged. It is also essential for safety reasons that the battery connectors be disconnected before removing the fuse F2 (located behind the hinged panel, see figure 23) to interrupt the battery circuit. - Stand on a rubber mat and use insulated tools. - Remove all personal effects, rings, watches, pens, which might cause a short circuit when working on the battery. Batteries are live at all times and short circuits can melt metals and cause injury, damage or fire. - DO NOT smoke or use naked flames, and avoid creating arcs or sparks when working on the equipment; do not wear clothes which may generate static electricity. - The sealed lead-acid batteries contain sulphuric acid. If a battery container is broken any acid leaking will cause burns on contact with skin and attack metal, paint and fabrics. Any area contaminated with acid should be thoroughly washed with large volumes of clean water. Rubber gloves should be worn when handling damaged batteries. i) Remove front panel see figure 10 ii) Remove the battery compartment panel by unscrewing the fixing screws at the front. DO NOT remove the safety ground connection. Battery connections are provided with the UPS. Each battery is provided with fastenings. Internal batteries are housed on three shelves at the bottom of the equipment as shown on figure 23. If the batteries are fitted, starting with the lower shelf first, remove the packaging. Connect the batteries to the UPS using the plug/socket connectors provided. If batteries are not already assembled on the shelves arrange then as figures 24 (depending on the battery size), strapping the batteries to the tray as shown. Starting with the lower shelf, fit and connect the batteries. Ensure that the polarities are correct in accordance with the relevant battery layout diagram. For each shelf make sure that the polarities are correct and the overall battery shelf voltage is at least 108v for the bottom two shelves and 72v for the top shelf. Replace the fuse F2, then connect the intershelves connectors and all panels in reverse order of removal before operating the equipment. page 62 -- MI00/10056 rev.1--05/2001 13.2 EDP70 PLUS/24/18/12 : Optional Battery Cubicle The battery autonomy can be increased by employing either one or two optional battery cubicles.
