1.0 INTRODUCTION

1.1 Summary of the manual

This handbook provides for the safe installation, startup and use of the MEPEM Uninterruptible Power System (UPS).

The Company recommends that the equipment be installed and regularly maintained by a Chloride Authorized personnel.

DO: - read the User Handbook before operating the MEPEM UPS.

- keep a log of all incidents.

- protect the batteries from damage. Batteries leak acid; avoid contact with skin, clothes or eyes.

DO NOT: - operate the control switches.

- operate the MEPEM UPS with any covers removed.

- obstruct the ventilation grilles.

1.2 Summary of the equipment

The MEPEM 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 MEPEM 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 MEPEM 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 MEPEM UPS. Refer to current publication for detailed specification.

The block diagram, shows the main functional sub-assemblies of the MEPEM 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 MEPEM 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

Figure 1 – Block diagrams – 20/30kVA page 10 – UPLIT042 rev.4 - 05/2005

Figure 2 – Block diagram – 50/75kVA

The uninterruptible power system consists of the following:

1 - RECTIFIER/INVERTER S1 = Equipment ON/OFF switch 2 - BATTERY S2 = Equipment Reserve switch 3 - BACKFEED PROTECTION S3 = Equipment By-pass switch 4 - INVERTER STATIC SWITCH S4 = Equipment OUTPUT switch 5 - RESERVE STATIC SWITCH (INVERTER OUTPUT switch for 50/75kVA only) S5 = RESERVE OUTPUT switch for 50/75kVA only

1.4 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.

UPLIT042 rev4 - 05/2005-- page 11

1.5 Operational modes

Figure 3 – Normal operation During normal operation the load is supplied by the mains through the rectifier and inverter. The rectifier also supplies the current for recharging and maintaining the battery in a fully charged state.

Figure 4 – Utility Supply failure

When the utility supply voltage is absent or outside the allowed tolerances, the battery supplies the 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.

page 12 – UPLIT042 rev.4 - 05/2005

Figure 5 – Re-establishing the Utility Supply When the utility supply returns within acceptable limits, the UPS returns automatically to normal operation mode as previously described. The rectifier now starts to recharge the battery. However, until recharge has been completed, any further mains failure will result in reduced standby times.

Figure 6 – Transferring the Load onto the Reserve Supply Transfer onto the reserve line is caused by two conditions:

a) inverter stop

b) overload In both instances the load is transferred onto the reserve without interruption. If the overload is temporary, the system will re-transfer from reserve to inverter as soon as it ceases. This allows for the initial start-up of loads with high or excessive switch-on currents.

UPLIT042 rev4 - 05/2005-- page 13

4.4 Ventilation

UPS can work in a continuous environment within 18°F[-10°C] to 104°F [+40°C ] temperature range, although, ideally the ambient temperature should be below 78°F [25°C].

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 T k / T

Tr - Tk with: V = air flow [mc/h]

Pd = total dissipated power [kW]

Tr = max. temperature allowed into the room [104°F = 40°C = 313°K]

Tk = Temperature of input cooling air

T0 = 273 °K h = altitude above the sea level [km]

5.4 Signal connections

a) 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.

b) Thermostick connector (50/75kVA only)

This connection provides the customer with remote control over the output transformer Overtemperature Alarm (TCORE = 175°C).

NOTE: If more than one of the above applications (or similar) are installed, the contacts MUST be connected in series.

8.0 MAINTENANCE BYPASS

The MEPEM UPS is equipped with Manual Maintenance Bypass systems. 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 18, 21 or 20) to ON.

4. Turn off the Primary Input, Reserve Input and UPS Output Switches, see figure 18, 21 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 50/75kVA 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: The MEPEM UPS must not be left operating with the Maintenance Bypass Switch in the ON position.

UPLIT042 rev4 - 05/2005-- page 45

9.0 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 MEPEM should be shut down each evening by using the shutdown procedure.

This will prevent the battery from discharging.

If, on the other hand, the supply to the site is continuous, the MEPEM should be operated 20 hours a day.

page 46 – UPLIT042 rev.4 - 05/2005

10.0 VISUAL AND AUDIBLE ALARMS
