Chapter 1 Product Introduction

1.1 System Configuration

The Tower UPS is configured by the following part: Rectifier, Charger, Inverter, Static Switch and Manual Bypass Switch. One or several battery strings should be installed to provide backup energy once the utility fails. The UPS structure is shown in Fig. 1-1.

Fig.1-1 UPS Configuration

1.2 Operation Mode

The Tower UPS is an on-line, double-conversion UPS that permits operation in the

following modes:

 Normal mode  Battery mode  Bypass mode  Maintenance mode (manual bypass)  ECO mode  Auto-restart mode  Frequency Converter mode

1.2.1 Normal Mode

The inverter of power modules continuously supply the critical AC load. The

rectifier/charger derives power from the AC mains input source and supplies DC power to the inverter while simultaneously FLOAT or BOOST charging its associated backup battery.

Fig.1-2 Normal mode operation diagram

Page 10

Chapter 1 Product Introduction

HSTP3T 10-40 KE/KEBC/KEBCWOB User Manual

1.2.2 Battery Mode

Upon failure of the AC mains input power, the inverter of power modules, which obtain power from the battery, supply the critical AC load. There is no interruption in power to

the critical load upon failure. After restoration of the AC mains input power, the” Normal

mode” operation will continue automatically without the necessity of user intervention.

Fig.1-3 Battery mode operation diagram

1.2.3 Bypass Mode

If the inverter overload capacity is exceeded under Normal mode, or if the inverter

becomes unavailable for any reason, the static transfer switch will perform a transfer of the load from the inverter to the bypass source, with no interruption in power to the critical AC load. Should the inverter be asynchronous with the bypass, the static switch will perform a transfer of the load from the inverter to the bypass with power interruption to the load. This is to avoid large cross currents due to the paralleling of unsynchronized AC sources. This interruption is programmable but typically set to be less than 3/4 of an electrical cycle, e.g., less than 15ms (50Hz) or less than 12.5ms (60Hz). The action of transfer/re-transfer can also be done by the command through monitor.

Fig.1-4 Bypass mode operation diagram

1.2.4 Maintenance Mode (Manual Bypass)

A manual bypass switch is available to ensure continuity of supply to the critical load

when the UPS becomes unavailable e.g. during a maintenance procedure. (See Fig.1-5).

Page 11

HSTP3T 10-40 KE/KEBC/KEBCWOB User Manual

Chapter 1 Product Introduction

Fig.1-5 Maintenance mode operation diagram

Danger

During Maintenance mode, dangerous voltages are present on the terminal of input, output and neutral, even with all the modules and the LCD turned off.

1.2.5 ECO Mode

To improve system efficiency, UPS rack system works in Bypass mode at normal time,

and inverter is standby. When the utility fails, the UPS transfers to Battery Mode and the inverter provide powers to the loads.

Fig.1-6 ECO Mode operation diagram

Note There is a short interruption time (less than 10ms) when transfer from ECO mode to battery mode, it must be sure that the interruption has no effect on loads.

1.2.6 Auto-restart Mode

The battery may become exhausted following an extended AC mains failure. The

inverter shuts down when the battery reaches the End of Discharge Voltage (EOD). The

UPS may be programmed to “System Auto Start Mode after EOD”. The system starts

after a delay time when the AC main recovers. The mode and the delay time are programmed by the commissioning engineer.

Waring

Once the cover on the maintenance bypass breaker is removed, the system will transfer to bypass mode automatically.

Waring

Before making this operation, confirm the messages on LCD display to be sure that bypass supply is regular and the inverter is synchronous with it, so as not to risk a short interruption in powering the load.

Danger

Even with the LCD turned off, the terminals of input and output may be still energized. If you need to maintain the UPS, wait for 10 minutes to let the DC bus capacitor fully discharge before removing the cover.

4.2.5 Switching the UPS into Normal Mode from Maintenance Bypass Mode

These following procedures can transfer the load from the Maintenance Bypass Mode to inverter output.

1. After finish of maintenance, close the output, bypass breakers and bypass static switch will be turned on in 30S after the LED screen goes on, the bypass indicator goes green and the load is powered through maintenance bypass and static bypass.

2. Turn off the maintenance bypass switch and fix the protection cover, and then the load is powered through bypass static switch.

3. Select the icon of and select

Fault Clear

to turn on the inverter.

4. After 60S, the system transfers to Normal Mode.

Waring

The system will stay on bypass mode until the cover of maintenance bypass breaker is fixed.

4.3 Battery Maintenance

If the battery is not discharged for a long time, it is necessary to test the condition of the

battery.

Enter the menu ，as is shown in Fig.4-3 and select the icon

MaintTest

，the system

transfers into the Battery mode for discharging. The system will discharge the batteries until

the alarm of “Battery low voltage” is given Users can stop the discharging by the “Stop Test”

Parallel system connection

For field installation, please connect the cables according to Fig.4-6 and Fig.4-8. In order to assure that all units are equally utilized and to comply with relevant wiring rules, the following requirements apply:

1. All units shall be of the same rating and must be connected to the same bypass source.

2. The bypass and the main input sources must be referenced to the same neutral potential.

3. Any RCD (Residual Current detecting device), if installed, must be of an appropriate setting and located upstream of the common neutral bonding point. Alternatively, the device must monitor the protective earth currents of the system. Refer to the High Leakage Current Warning in the first part of this manual.

4. The outputs of all UPS must be connected to a common output bus.

Parallel system software setting

To change the parallel system setting, please follow the steps below.

1. With the monitoring software from manufacturer, select the page of “Service Setting” as below,

Set “System Mode” to “Parallel”, and set the “United Number” to the number of units in

parallel. For the setting of system ID with a system of 3 units in parallel, for example, set the number from 0 to 2 for these 3 units accordingly. Restart the UPS when finish the setting and press the button of “Set”. Here the software setting is done. Ensure all the output parameters must be set the same.

Parallel system jumper setting

There are different setting of the jumpers on the parallel board and control board for different parallel system. The location of connectors on parallel board is shown in Fig.4-11 and control board in Fig.4-12.

1. Parallel boards settings A. For single UPS, no need parallel board. When a parallel board is installed, connectors of

J33 to J42 should be shorted by the jumpers.

B. For 2 UPS in parallel, short the connectors of J33/J35/J37/J39/J41 by jumpers on each

board, keep connectors of J34/J36/J38/J39/J42 open

C. For 3 or 4 UPS in parallel, keep connectors of J33-J42 open.

2. Control boards settings

The control board is named as PS1203_CT1. For single UPS, keep the J21-J25 shorted by jumpers For parallel, keep all the connectors J21-J25 open. As is shown in Fig.4-12.

Note: The connectors not mentioned keep them untouched.

When all the connection and settings are finished, follow the steps below for the operation of parallel system setup.

1. Close the output and input breaker of the first unit. Wait for the startup of bypass static

switch and rectifier, about 90 seconds later; the system will transfer to normal mode. Check if there is any alarm on LCD and verify the output voltage is correct or not.

2. Turn on the second unit as the same operation with the first one; the unit will join the

parallel system automatically.

3. Turn on the rest units one by one, and check the information on LCD.

4. Verify the load sharing with a certain load applied.

Chapter 5 Maintenance

This chapter introduces UPS maintenance, including the maintenance instructions of power

module and monitoring bypass module and the replacement method of dust filter.

5.1 Precautions

1. Only certified engineers are authorized to maintain the UPS.

2. The components or PCBs should be disassembled from top to bottom, so as to prevent any inclination from high gravity center of the cabinet.

3. To ensure the safety before maintaining, measure the voltage between operating parts and the earth with multi-meter to ensure the voltage is lower than hazardous voltage, i.e. DC voltage is lower than 60Vdc, and AC maximum voltage is lower than 42.4Vac.

4. Wait 10 minutes before opening the cover of the power module or the bypass after pulling out from the Cabinet.

5.2 Instruction for Maintaining UPS

For the maintenance of the UPS, please refer to chapter 4.2.4 for the instruction to transfer to maintenance bypass mode. After maintenance, re-transfer to normal mode according to chapter 4.2.5.

5.3 Instruction for Maintaining Battery string

For the Lead-Acid maintenance free battery, when maintenance the battery according to requirements, battery life can be prolonged. The battery life is mainly determined by the following factors:

1. Installation. The battery should be placed in dry and cool place with good ventilation. Avoid direct sunlight and keep away from heat source. When installing, ensure the correct connection to the batteries with same specification.

2. Temperature. The most suitable storage temperature is 20 ºC to 25ºC. The battery life will be shortened if the battery is used under high temperature or in deep discharging status. Refer to product manual for details.

3. Charging/discharging current. The best charging current for the lead-acid battery is

0.1C .The maximum current for the battery can be 0.3C.The suggested discharging current is 0.05C-3C.

4. Charging voltage. In most of the time, the battery is in standby state. When the utility is normal, the system will charge the battery in boost mode (Constant voltage with maximum limited) to full and then transfers to the state of float charge.

5. Discharge depth. Avoid deep discharging; which will greatly reduce the life time of the battery. When the UPS runs in battery mode with light load or no load for a long time, it will cause the battery to deep discharge.

6. Check periodically. Observe if any abnormality of the battery, measure if the voltage of each battery are in balance. Discharge the battery periodically.

Warning

Daily inspection is very important! Check and confirm the battery connection is tightened regularly, and make sure there is no abnormal heat generated from the battery.

Warning

If a battery has leakage or is damaged, it must be replaced, stored in a container resistant to sulfuric acid and disposed of in accordance with local regulations.

The waste lead-acid battery is a kind of hazardous waste and is one of the major contaminants controlled by government. Therefore, its storage, transportation, use and disposal must comply with the national or local regulations and laws about the disposal of hazardous waste and waste batteries or other standards. According to the national laws, the waste lead-acid battery should be recycled and reused, and it is prohibited to dispose of the batteries in other ways except recycling. Throwing away the waste lead-acid batteries at will or other improper disposal methods will cause severe environment pollution, and the person who does this will bear the corresponding legal responsibilities.
