General Description

2.1 Introduction

Congratulations on your purchase of the PW1000 1-3kVA UPS.

High reliability, low operating cost and excellent electrical performance are just some of the highlights of this innovative
UPS solution.

Uninterruptible Power Supplies Ltd. specialises in the installation and maintenance of Uninterruptible Power Systems; and
this UPS is just one example of our wide range of state-of-the-art power protection devices that will provide your critical
equipment with a steady and reliable power supply for many years.

2.1.1 Advanced design features

By using the latest technological developments in power engineering, the PW1000 1-3kVA represents a new generation of
transformerless UPS-System. Its advanced double conversion Voltage and Frequency Independent (VFI) topology
responds fully to both the highest availability and environmentally friendly requirements, compliant with IEC 62040-3 (VFI­SS-111) standards. A full UPS specification is provided in Chapter 8 of this manual.

Following, are some of this unit’s advanced design features:

• True online technology continuously supplies your critical applications with stable, regulated, transient-free pure

sine-wave AC power.

• High-Frequency Transformerless technology and tower-convertible enclosure enables the UPS to be integrated

into even the most difficult environments with space constraints.

• User-friendly design that permits simple and trouble-free installation. All units are supplied with input and output

power cables as standard.

• Smart battery management system which extends the battery life span.

• Highly efficient PWM sine-wave technology yields excellent UPS efficiency. The high crest factor of the inverter

handles peak inrush current loads and so avoids a need to upgrade to a UPS with a higher power rating.

• Compliant with various stringent international EMC standards for electromagnetic interference & protection.

• Selection of output voltages (200/208/220/230/240) available to match the UPS to local supply specifications or

specific load voltage requirements.

• A selectable bypass voltage tolerance (low/high sensitivity) restricts the range of voltages that can be applied to the

load when the UPS operates on bypass. The ranges are ±15% (low sensitivity) and ±10%V (high sensitivity). For
example, if the output voltage setting is 230V the bypass sensitivity Low range is 230V ±15%.

• Selectable 50Hz or 60 Hz operation.

• Fully digitized control logic for better functionality and enhanced power protection. Digital signal processing (DSP)

also provides efficient communication capabilities for enhanced remote control and monitoring flexibility.

• Active power factor correction (PFC) control function constantly maintains the UPS input power factor to >0.99 at

100% load, with resulting outstanding energy efficiency.

• Wide input voltage tolerance, from 110V~300V, allows the UPS to operate normally without draining the battery

unnecessarily during significant mains voltage dips, which helps extend the battery service life.

• DC-start function permits the UPS to be started during a utility power failure if required.

• Overload protection system automatically switches the UPS to bypass mode if an overload occurs and

automatically switch back to inverter mode once the overload condition ceases. Should the output become short­circuited, the UPS puts the system in stand-by mode, provides visible and audible alarms, and turns off the output
supply automatically until the short circuit situation is resolved manually.

2.1.2 PW1000 1-3kVA Model range

The PW1000 1-3kVA UPS range comprises 1 kVA, 2 kVA and 3 kVA models, each of which is designed as a self­contained UPS comprising a rectifier, battery charger, inverter, static switch and battery pack. All the models in this range
are easy to install, and supplied with suitably terminated power cables.

The PW1000 1-3kVA operates as a stand-alone UPS module and can be mechanically configured as a floor-standing
tower unit or installed in a standard 19 inch rack. An accessory pack which contains all the parts necessary to configure
the unit for either type of installation is supplied with the UPS.

Optional external battery cabinets are available to increase the UPS autonomy time. The battery cabinet design
compliments the UPS cabinet and the two cabinets can be mechanically connected together to form a single unit when
installed as a tower system – see chapter 3 (Installation) for mechanical configuration details.

2.2 UPS Operating principles

2.2.1 Basic block diagram

Figure 2.1 UPS Functional block diagram

EMI Filters

The UPS has an input and output EMI filter to reduce the effects of electromagnetic noise generated by the UPS on other
adjacent equipment – e.g. reduces external radio interference.

Battery charger

A regulated battery charger, power from the AC Input supply, charges the battery whenever the input supply is available.

DC/DC Boost converter

In times of AC Input supply failure, the DC/DC Boost Converter turns on and boosts the battery voltage to a level suitable
for use by the inverter. It provides a regulated DC output for the inverter while the battery voltage decays during discharge
and includes voltage and current monitoring and overload protection.

2: General Description

AC/DC Converter

As its name suggests, the AC/DC Converter converts the AC Input supply into a controlled DC supply that is suitable for
use by the inverter. The converter uses a leading-edge switched-mode technique which produces an input power factor of
almost unity over its full operating range (0.99 at full rated linear load) and thereby maximises the UPS efficiency.

The converter can satisfy the inverter DC power demands over an AC Input voltage range of between 110V~300V which
means that the battery is not called upon during power dips (brownouts), thereby maximising battery life and availability.

DC/AC Inverter

The inverter converts the DC voltage connected to its input, from the AC Input supply via the AC/DC converter or from the
battery via the DC/DC converter, and produces a regulated AC Output voltage that is suitable to power the connected load
equipment. The control logic associated with the Inverter power block is substantial, and in addition to the controlling the
output sine wave voltage it also provides various levels of overload protection, frequency regulation and synchronisation,
and output voltage error detection.

Static switch

The static switch provides a means of connecting the UPS AC Output (load) to the inverter output or the bypass line,
which is connected directly to the UPS AC Input. The control logic within this power block will transfer the load to the
bypass supply in the event of overload or UPS (inverter) malfunction. The load can also be transferred between the
inverter and bypass line manually if required. Note that a controlled transfer can take place only if the inverter and bypass
line are synchronised in frequency and phase.

2.3 Operator control panel

The UPS is controlled from the operator control panel located on the front of the unit.

The user-friendly UPS control panel comprises three areas:

Figure 2.5 Operator control panel

2.3.1 LED Indicators

Input mains supply status

This led is permanently ON if the mains supply is within in the normal operating range of 160~300 VAC, and
flashes if the supply falls to 120~159 VAC. If the led is OFF it indicates a mains supply failure.

Programmable outlet status

The programmable outlets are normally connected to less critical loads which can be shed when the utility
power fails. This reduces the load on the battery as it discharges and thereby increases the back-up time for
the more critical loads which are connected to the unswitched UPS outlet(s). The indicators are permanently
ON when the outlets are live.

Bypass supply status

This led is permanently ON when the UPS is operating in the ECO mode and flashes when the load is
transferred to bypass – either manually or due to a detected fault.

UPS fault indication

This LED illuminates to indicate the presence of a fault condition within the UPS that needs attention. It is
usually accompanied by an audible alarm.

2.4.1 Communication Ports

Several communication options can connected to the PW1000 1-3kVA. These are described briefly below with further
details provided in Chapter 7 (Options).

USB port (Figure 2.7 item 3)

A USB type B socket is provided to allow the UPS to be connected to a PC using a standard USB peripheral interface
cable. The USB communication protocol complies with USB version 1.0 (1.5 Mbps) and USB HID version 1.0. This facility
can be used in conjunction with UPS monitoring and shut down software (not supplied).

RS-232 Interface port (Figure 2.7 item 2)

The RS-232 port allows the UPS to be connected to a PC and provides the same functions as the USB port.

Emergency power off (EPO) (Figure 2.7 item 1)

If an external emergency power off (EPO) facility is required, the external circuit must be connected to the two pin plug
located on the rear panel. A plug-in connector with screwed terminal connections is supplied ready fitted to the EPO
socket to simplify the connection of the external cable if the UPS is located in a confined space, such as when it is rack
mounted. The EPO input requires a normally-open contact which closes to active the EPO function. If the UPS is shut
down by the EPO input (closed), it has to be restarted manually after the EPO input is removed (opened).

Optional interface cards (Figure 2.7 item 4)

An optional SNMP/ CS141 interface card can be fitted in the card slot to enable the UPS to be integrated into a network
monitoring and control system.

ON BYPASS

This mimic is displayed if the UPS develops a fault, or is overloaded, whereupon the
LOAD is transferred to the bypass line and connected directly to the utility supply
(INPUT). The battery will remain on charge if the UPS battery charger is healthy.

Maintenance

5.1 Introduction

The UPS does not contain any user-serviceable parts, so the day-to-day maintenance requirements are minimal other
than to ensure that the environment in which the UPS is installed is kept cool and dust free. A clean, controlled operating
environment will help maximise the useful working life and reliability of both the UPS and its batteries.

5.2 Scheduled maintenance

The UPS system and batteries should receive regular preventative maintenance from a trained engineer to maximise both
the useful working life and system reliability. If the UPS is commissioned by a Uninterruptible Power Supplies Ltd. service
engineer, the engineer will leave a service record book with the UPS which will be used to log its full service history.

We recommend that the UPS system is maintained every six months by an Uninterruptible Power Supplies Ltd. trained
engineer or approved service agent, who will complete the following. Preventative maintenance inspections form an
integral part of all Extended Warranty Agreements (maintenance contracts) offered by Uninterruptible Power Supplies Ltd.

5.2.1 Preventative maintenance inspection

During a preventative maintenance inspection a trained Uninterruptible Power Supplies engineer will check and validate:

• Site environmental conditions

• Integrity of the electrical installation

• Cooling airflow

• Load characteristics

• Integrity of alarm and monitoring systems

• Operation of all installed options

• All stored event logs

5.2.2 Battery maintenance and testing

The batteries should be inspected and tested every six months, depending on the ambient temperature.

The battery test takes approximately two minutes to complete and can be performed only if:

• There are no alarm conditions present.

• The battery is fully charged.

• The UPS input mains supply is present.

The battery test procedure can be carried out from the UPS front panel and performed irrespective of the UPS operating
mode (ON-INVERTER or ON-BYPASS/ECO) and whether or not the load is connected.

WARNING: Do not remove the covers from the UPS case. If you remove a cover from the UPS case you will
be exposed to potentially lethal voltages.

Troubleshooting

6.1 Introduction

If the UPS shuts down due to a fault condition, caused by an internal malfunction or severe overload, it might need to be
reset to bring it back into operation – see paragraph 6.6. Depending on the nature of the fault, the UPS may either shut
down entirely and disconnect the load supply or transfer the load to the internal bypass.

6.2 Fault identification

Unless there is a total UPS failure, the UPS will generally:

• illuminate the red FAULT LED

• display a Buzzer Code (error code) number on the LCD screen – the code indication may be steady or flashing

depending on other factors

• sound the audible warning alarm – the audible warning may be cancelled by pressing the ON button briefly

• illuminate the warning symbols at the top of the LCD screen if applicable

The UPS output is overloaded

Service:

The UPS is operating in its service mode

Alarm:

An alarm condition is present. This remains active after the audible alarm is reset if the alarm still exists.

Buzzer Code Possible Solution

05 / 39

Battery problem:

1. When applicable, check that the external battery connections have been made correctly.

2. Measure the battery voltage to ensure it is charged and in good condition.
Recharge battery for 8 hours if necessary.

3. Simulate a utility supply outage to establish that UPS is able to provide DC back-up.

4. Seek advice from your local service agent if you find no problem with the above.

06

Emergency Power Off (EPO):

1. If the external EPO mechanism has been intentionally operated, investigate the reason and rectify any external
problems before you restore the UPS operation.

2. If the external EPO mechanism has not been intentionally operated, investigate the external EPO circuit to trace
the source of the erroneous EPO command. The external circuit applies a short circuit to the EPO connector on
the back of the UPS to effect an EPO shut down.

3. If the external EPO circuit is not faulty, seek advice from your local service agent.

Overload:

1. Disconnect any non critical loads from the UPS output until the overload ceases.

2. Check the condition of the output cables and connectors to determine that they are undamaged and the insulation
is sound. Replace the output cables if necessary.

3. Seek advice from your local service agent if you find no problem with the above.

11

UPS Over temperature:

1. Remove any objects obstructing the ventilation louvres.

2. Check to ensure that the cooling fans are working properly (see also buzzer code

6.4 Troubleshooting an operational problem

6.5 UPS Fault handling

ON INVERTER overload

The UPS is equipped with an electronic overload protection feature which switches the load to the bypass line after 30
seconds if the UPS load rises to between 105% ~ 120% of its rated capacity. This is reduced to 10 seconds for loads
between 121% ~ 150%, with an instant transfer taking place for loads greater than 150%.

If the load transfer is due to starting a load with a high inrush current, the overload will be short-lived, and once the current
being drawn from the bypass falls below <105% of rated load, the UPS will switch back to inverter mode automatically.

If the UPS appears to be repeatedly momentarily overloading, it could be due to the inrush currents being produced as
various multiple loads are started.

ON BATTERY overload

When operating ON BATTERY, the UPS overload characteristics are identical to when operating ON INVERTER. The
difference is that, due to the lack of bypass supply, the UPS is unable to transfer the load to bypass if the load capacity/
time characteristic is exceeded, so the UPS will shut down.

Site wiring/earth fault:

1. Check that the utility AC source ‘L’ & ‘N’ have been wired correctly.

2. Check that the earth/ neutral voltage does not exceed the limits specified in chapter 8.

3. Seek advice from your local service agent if you find no problem with the above.

14

Fan error:

1. Verify that the ventilating fans are functioning properly.

2. Contact your local service agent for fan replacement. Do not attempt to replace them yourself.

Other For all other error codes, seek advice from your local service agent.

Symptom Possible Solution

UPS fails to provide battery back-up, or the back-up time
is shorter than its specified performance.

1. Charge the battery for eight hours.

2. If the back-up time remains unsatisfactory after 8 hours of charging,
please contact your local service agent for battery replacement.

UPS operation appears to be normal but there is no
output to load.

1. Check that all output power cords are connected correctly.

2. If the problem is with one of the programmable outlets, seek service
support who will check the programmable outlets settings and recalibrate
them if necessary.

3. If the problem persists, seek advice from your local service agent.

The UPS switches to battery mode then back to on-line
mode, when the connected device is turned on.

Or, the UPS switches back and forth between battery
and on-line mode.

1. Check for a faulty UPS input cable or utility supply wall receptacle and
replace/repair any faulty item found.

2. If the problem persists, seek advice from your local service agent.

Strange noise and/or odour emitted by UPS 1. Shut down the UPS system immediately.

2. Turn off the utility mains supply.

3. Seek advice from your local service agent.

ON BYPASS overload

The UPS bypass line is also equipped with overload protection. Its overload capacity/time characteristics are illustrated in
the table below.

6.5.1 Output load short circuit when the output supply is via inverter

If output load is short circuited while it is being supplied via the inverter:

1. The inverter will immediately shut down and disconnect the supply to the load.

2. The FAULT led will illuminate and the audible alarm will beep continuously.

3. The UPS will not switch on automatically after the short-circuit condition is eliminated. It has to be re-started manually.

6.5.2 Output short-circuit when the output supply via the bypass line

If the output load is short-circuited while the UPS is operating in ON BYPASS mode:

1. The utility supply fuse/breaker will open to prevent the output load from damage.

2. You must replace the fuse with a fuse of the same rating after the cause of the short-circuit condition has been
rectified.

6.5.3 Inverter/internal over-temperature

If the UPS experiences an internal over-temperature when the utility supply is normal it will switch to ON BYPASS mode
and switch back to ON INVERTER mode when the over-temperature situation has been eliminated.

If over temperature occurs when the utility supply is abnormal:

1. The audible alarm will beep continuously.

2. The FAULT led will illuminate.

3. The inverter will shut down and disconnect the load supply.

6.5.4 Inverter over-current and output voltage out of tolerance

If the UPS develops a fault and its inverter delivers an over-current and out-of-tolerance voltage:

1. The UPS will switch to ON BYPASS mode as long as the utility supply is normal.

2. The UTILITY led, BYPASS led and FAULT led will illuminate.

If these fault conditions occur when the utility supply is abnormal:

1. The inverter will shut down and disconnect the load supply.

2. The FAULT led will illuminate.

6.6 UPS System reset

The UPS control system may ‘lock-up’ following a critical abnormal failure condition. If the UPS appears unresponsive to
control operations you can reset it using the following procedure:

1. Note and record the error code shown on the LCD screen, and check the information in this chapter to help analyse
the cause of the UPS problem. This will be useful if you need to contact the service support centre later.

2. Press an hold the OFF button for at least five seconds.

3. Turn off the utility mains power supply and allow one minute for the UPS control power supply to completely shut
down.

4. The UPS control system is now reset and, if the cause of previous fault condition is no longer apparent, you should be
able to turn on the UPS as normal.

5. If you are unable to restart the UPS then please seek service support.

Options

7.1 Communications options

The UPS has several provisions for communicating with external devices and systems, including:

• External Emergency Power Off (EPO) or Remote On/Off (ROO).

• RS-232 and USB ports to provide communication with monitoring software installed on a remote PC.

• Optional card slot that can be used with an intelligent CS141 card for local or area network UPS monitoring and

control, or a Dry Contact relay card to provide volt-free signalling that can be integrated into an external alarm
monitoring or building management system.

All communication ports, including the optional cards, can be active and used simultaneously to monitor the UPS status;
however, only one communication interface at a time can control the UPS. This is determined on a priority basis, with the
higher priority interface gaining control.

The interface control priorities are as follows:

• EPO input port

• Optional interface card

• Optional USB

• Optional RS-232

7.2 RS-232 Computer serial interface

Figure 7.1 RS-232 Serial communications port

Note: The USB port is connected in parallel with RS-232 port and outputs the same data stream.

When used in conjunction with suitable software, the RS-232 and USB ports allow the connected PC to continuously
monitor the input mains voltage and UPS status, and display appropriate operating data and messages.

The RS-232 connector is a 9-pin female D-type and can be connected to a PC using standard serial cable wired as shown
in Figure 7.1. The maximum permitted RS-232 cable length is 15 metres.

7.3 Emergency Power Off (EPO) / Remote ON/OFF (ROO)

Figure 7.2 EPO Connection

The Emergency Power Off (EPO) option allows you to turn off the UPS using an external switch or contact that is wired to
the EPO terminal block on the back of the UPS. The external circuit consists of a ‘normally open’ external contact that will
power-off the UPS when the contact is closed.

When the EPO circuit is activated the UPS output is
shut down, removing power to the load, but the
battery charger remains operational to maintain
battery charging. An EPO alarm is shown on the LCD
display but you can still scroll through and monitor
the UPS input, battery and output metering.

Once the external EPO command is removed, the
UPS must be restarted by pressing the UPS ON
button to restore the UPS to normal operation.

The external EPO connection should be made using
a screened, single pair cable (0.5mm²) with a
maximum length of 100 metres.

7.4 CS141 /SMNP adapters

Figure 7.4 SNMP Adapters

Simple Network Management Protocol (SNMP) is a world-wide, standardised communication protocol that can be used to
monitor any network-connected device via a simple control language and display the results in a browser-based
application. The software agent built in to the CS141 adapter card makes the UPS data available in this SNMP format
which can then be utilized by a number of UPS management software applications.

The card contains a serial interface, which can be connected directly to a computer’s serial port, and an RJ-45 connector
which allows it to be connected to a network using a standard CAT-5 cable. The SNMP adapter can be configured via
Telnet, http (browser) or serial connection. For normal operation, at least one Ethernet network connection is necessary.

7: Options

Once installed, the UPS-Management software agent, which is already installed in the card, monitors the UPS operation
and outputs its data in SNMP format to the connected network. The card enables automated generation of event/alarm
emails, server controlled shut down (with optional licenses) and other tasks, and can also be integrated with BMS software
over a local area network (LAN) for SNMP or Modbus information over IP.

Uninterruptible Power Supplies Ltd. offer monitoring software with SNMP functionality for Novell, OS/2, and Windows that
run both on INTEL and on ALPHA, DEC VMS and Apple.

An optional external SNMP adapter can be connected to the UPS via its RS232 port if the UPS card slot is in use (e.g.
DCE card fitted) but SNMP facilities are still required.

RCCMD

RCCMD (Remote Console Command Module) for ‘multi-server shut down’ is an independent software module intended
for transmitting and receiving ‘remote commands’. Using the ‘RCCMD send’ function, the SNMP adapter can send status
messages to connected users or initiate automatic shut down throughout the whole network. Our CS141 SNMP adapters
are fully compatible with RCCMD.

7.5 AS400 (dry contact) card

The DCE dry contact card provides volt-free
signalling outputs that can be integrated into an
external alarm monitoring panel or building
management system.

All the output connections at pins 1-7 are
switched by relays whose pole contacts are
connected to terminal 8 (common). Figure 7.5
shows an example of the INVERTER ON relay.
Note that all the outputs to terminals 1-7 are link­selectable to be either short-circuited or open­circuited to the common Pin 8 when the
monitored parameter is ‘active’. Details for
configuring the links are provided in the
documentation that accompanies the card.

Terminals 9 an 10 are inputs that can be used to
shut down the UPS when en external voltage of
6-25VDC is applied, as shown.
