General Description

Reliability and Quality Standards

Congratulations on your purchase of the PW8000DPA ST.
Using a unique modular construction, the PW8000DPA ST represents a completely new generation of medium power, 3
phase UPS-Systems, incorporating the latest technological developments in power engineering. High reliability, upgrade
ability, low operating costs and excellent electrical performance are only some of the highlights of this innovative UPS
solution.
Uninterruptible Power Supplies Ltd specialises in the design, building, installation and maintenance of Uninterruptible
Power Systems. This compact and powerful UPS is just one example of our wide range of state-of-the-art power
protection devices and will provide your critical equipment with a steady and reliable power supply for many years.
The criteria and methods which are used in the design, manufacture, and maintenance of Uninterruptible Power Supply
systems are certified to International Standard ISO 9001/EN 29001 and ISO 14001. A full UPS Specification is given in
Chapter of this manual.

2.2

PW8000DPA ST System

PW8000DPA ST is a truly modular system based on 10kVA or 20kVA UPS modules which can be connected in parallel to
form a redundant-module system.
The UPS modules are assembled in a range of purpose-designed free-standing cabinets containing up to six UPS
modules, batteries and system switch-gear.
Cabinet-mounted systems are rated according to the maximum number of 20kVA modules that can be housed – i.e.
40kVA, 60kVA, 80kVA, 120kVA and 200kVA (see Figure 2.1). The 40kVA and 60kVA cabinets also contain the UPS
batteries whereas these must be located externally in the 80kVA, 120kVA and 200kVA cabinets.
Key Point: All the modules fitted within a cabinet must be of the same rating – i.e. it is not possible to mix 10kVA
and 20kVA modules in the same parallel system.

2.3

System Configuration

The illustrations in Figure 2.1 show the available cabinets fully populated with either 2, 3, 4, 6 or 10 UPS modules;
however each of the systems shown can operate with as little as a single module fitted.
Thanks to the advanced PW8000DPA ST system design, if a cabinet is not fully populated it is possible to add further
modules, as required, to increase the system capacity without the need to power-down the system or in any way disrupt
the load. This ‘hot-swappable’ design also means that individual modules can be exchanged while the equipment is
running without the need to transfer the load to the bypass supply (depending on system redundancy and demanded
load).

Advanced Design Features

2.4.1 Input booster technology
The UPS module’s inbuilt advanced booster technology results in a perfect sinusoidal input power quality at 0.99 input
power factor with a harmonic content of 3% THD(i). This leads to a more reliable total system operation and savings in
generator and transformer sizing as losses in the windings are minimised. It also means that traditional harmonic filters
are no longer required.
The high power factor presented by the UPS on the incoming mains supply minimises cabling and fusing costs due to the
resulting lack of reactive power consumption. This, together with the accompanying low harmonic currents, provide the
following benefits:
•
•
•
•
•
•

No additional losses in wires and cables.
No extra heating of transformers and generators.
No over sizing of generators.
No false circuit breaker tripping and malfunction.
No erratic operation of computers, telecommunication, monitors, electronic test equipment etc.
No resonance with power factor correction capacitors.

2: General Description

2.4.2 Flexible battery management
This equipment employs a flexible battery management which avoids premature deterioration of battery life by advanced
management of battery charging and preventive failure diagnostics.
The major benefits are:
•
•
•
•
•
•
•
•

AC-ripple free battery charging due to a dc-dc charger separated from the rectifier and inverter.
Wide range of number of battery blocks (24-50 blocks of 12V; depending autonomy times).
UPS's wide input voltage operating window extends the battery life due to fewer discharge cycles.
Battery discharge protection caused by load jumps.
Proactive battery protection from false manipulations and inadequate charging voltages.
Proactive battery failure detection thanks to Advanced Battery Diagnosis (ABD) - Algorithm.
User selectable battery tests.
Optional temperature compensated charging to enhance battery life.

2.4.3 Decentralized Parallel Architecture (DPA)
The PW8000DPA ST system features DPA paralleling technology that provides n+x redundancy without introducing a
single-point-of-failure. The modules utilizing the DPA technology are completely autonomous be means of individual
power units, bypasses, CPUs, control panels and separate battery configuration.

2.5

Installation

Introduction

This chapter contains all the information necessary for the correct unpacking, positioning, cabling and installation of the
PW8000DPA ST UPS cabinet.
WARNING: All the operations described in this section must be performed by authorised electricians or
suitably qualified personnel.
Uninterruptible Power Supplies Ltd. will take no responsibility for any personal or material damage caused
by incorrect cabling or operations, or activities which are not carried out in strict accordance with the
instructions contained in this manual.

3.2

Receipt of the UPS

The UPS and accessories are delivered on a specifically designed pallet that is easy to move with a forklift or a pallet jack.
CAUTION: When off loading the UPS always keep it in an upright position.
Do not drop the equipment.
Do not stack the pallets due to the high-energy batteries involved and the heavy weight.
The packing container protects the UPS from mechanical and environmental damage. This protection is further increased
by wrapping the PW8000DPA ST UPS with a plastic sheet.
Upon receiving the UPS, carefully examine the packing container and the UPS for any sign of physical damage. The
outside 'Tip&Tel' (“FRAGILE” and “ARROW”) indicator should be intact if the equipment has been transported in an
upright position. In case of rupture (or if they are suspect) inform the carrier and Uninterruptible Power Supplies Ltd
immediately.
CAUTION: Visible transport damages must be notified to the carrier immediately after receipt!
Other claims for shipping damage must also be filed immediately and the carrier must be informed within 7
days of receipt of the equipment.
Packing materials should be stored for further investigation.
Ensure that the received UPS corresponds to the description indicated in the delivery note.

3.2.1 Site transportation
If you transport the UPS equipment after it has been off-loaded (for example, for storage or moving to a different
installation location) please observe the following precautions.
CAUTION: Transportation:
To avoid the UPS cabinets and/or battery cabinet falling over, use the shipping brackets on the rear and
front to secure the cabinets.
– Do not tilt the cabinets more than 10° from vertical.
CAUTION: Potential dangers:
– If the cabinet has been tilted it might damage the equipment and it should not therefore be connected to
the mains electricity supply.
– The weight of the UPS system could cause serious injuries to persons or anything in the surrounding area.

UPS454-01-02 PW8000DPA User Manual - (01-12-13)

3: Installation

CAUTION: Storage:
– The UPS should be stored in the original packing and shipping carton.
– The recommended storing temperature for the UPS system and batteries is between +5 °C and +40°C.
– The UPS system and the battery sets must be protected from humidity < 90% RF (non-condensing).

3.3

Unpacking
WARNING: The UPS system, the battery cabinet (option) and the batteries are heavy and may tip during
transportation causing serious injury if the unpacking instructions are not followed closely.

If the packages are received in good order (i.e. the ‘tip & tell’ “FRAGILE” and “ARROW” indications on the packing
container are intact) then perform the following steps to unpack the UPS:
1.

If the cabinet is shipped inside a wooden case, remove the screws at the base and sides of the case then carefully
remove the case from the equipment.

Cut the wrappers and remove the packing container by pulling it upwards.

Remove the plastic sheeting covering the UPS.

Remove the UPS from the pallet.

Retain the packaging materials for future shipment of the UPS.

Examine the UPS for any sign of damage.
Notify your supplier immediately if damage is apparent.

Open the cabinet door and ensure that all the UPS modules are correctly and securely fitted in their compartments.
Ensure that a protection cover is fitted to the front of any empty UPS compartments.

3.3.1 Nameplate
The technical specifications of the PW8000DPA ST are provided on the nameplate which is situated at the front (internal
door) of the UPS.
Check that the details on the nameplate corresponds to the purchased material detailed on the delivery note.

3.4

Batteries

The standard batteries connected to the UPS are sealed, maintenance-free batteries which will be mounted either within
the UPS cabinet or an external battery cabinet. The battery will usually be connected when the UPS is commissioned.
Battery life depends very much on the ambient temperature, and optimum battery life will be obtained if the batteries are
operated at a temperature of 20°C.
If the UPS is delivered without batteries, Uninterruptible Power Supplies Ltd is not responsible for any damage or
malfunctioning caused to the UPS by the incorrect storage, installation or connection of batteries by third parties.

UPS454-01-02 PW8000DPA User Manual - (01-12-13)

3: Installation

3.5

Storage

3.5.1 UPS
If you plan to store the UPS prior to use, store it in a clean dry environment with a temperature between +5°C to +40°C
and RH of less than 90%. If the packing container is removed, you must protect the UPS from dust.

3.5.2 Battery
The UPS utilizes sealed, maintenance-free batteries, whose storage capability depends on ambient temperature. It is
therefore important not to store the UPS for longer than 6 months at 20°C, 3 months at 30°C or 2 months at 35°C storage
temperature without recharging the batteries. For longer term storage the battery should be fully recharged every 6
months @20°C.
CAUTION: Sealed batteries must never be stored in a discharged or partially discharged state.
Extreme temperature, under-charge, overcharge or over-discharge will destroy batteries!
Key Point: Note the following:
•
•
•

3.6

Charge the battery both before and after storing.
Always store the batteries in a dry, clean, cool environment in their original packaging.
If the packaging is removed protect the batteries from dust and humidity.

Positioning

3.6.1 Planning the installation
A certain amount of pre-planning will help ensure smooth, trouble-free equipment installation. The following guidelines
should be taken into account when planning a suitable UPS location and environment.
1.

The equipment must be installed and transported in a upright position.

The floor at the installed location and en-route from the off-loading point must be able to safely take the weight of the
UPS and battery equipment plus fork lift during transit.

The UPS cabinet requires space to bottom/front and back to enable cooling airflow. Suitable ventilation airflow must
also be provided (See Figure 3.1). Allow a 200mm minimum clearance at the back of the cabinet.

All parts of the UPS required for maintenance, servicing and user operation are accessible from the front. Reserve a
minimum of 900mm space at the front of the UPS cabinet.

An ambient temperature of 20°C is recommended to achieve a long battery life. The cooling air entering the UPS must
not exceed +40°C.

Avoid high ambient temperature, moisture and humidity. The floor material should be non-flammable and strong
enough to support the heavy load.

In summary, the UPS should be located where:
a)
b)
c)
d)
e)
f)

Humidity (< 90% non-condensing) and temperature (+15°C to +25°C) are within prescribed limits.
Fire protection standards are respected.
Cabling can be performed easily.
A minimum 900mm front accessibility is available for service or periodic maintenance.
Requested air cooling flow is available.
The air conditioning system can provide a sufficient amount of air cooling to keep the room at, or below, the
maximum desired temperature.
g) No dust or corrosive/explosive gases are present.
h) The location is vibration free.
i) If the UPS will be installed in bayed enclosures, partition walls have to be installed.

UPS Power Cabling (preparation and planning)

3.7.1 General requirements
It is the customer’s responsibility to provide all external fuses, isolators and cables used to connect the UPS input and
output power supplies. The information in this section should assist in the planning and preparation of the UPS power
cabling.
The UPS input supply and bypass supply should be connected to the utility mains through a LV-Distribution board and
protected by a circuit breaker or fuse. This provides overload protection and also a means of isolating the UPS from the
mains supply when required. Similarly, the UPS output supply should be connected to the load equipment via a suitably
fused output distribution panel.
The UPS can be wired with a ‘single feed’ input (standard), whereby the UPS input supply is connected internally to the
UPS bypass circuit; or it can be wired with a ‘dual feed’ input, whereby the UPS bypass circuit is connected to a dedicated
‘bypass’ supply (See Figure 3.3).
Figure 3.3 identifies the UPS input/output cabling requirements and provides information regarding fuse ratings, cable
ratings and cable sizing. This information is given for guidance only.
Key Point: This information is given for guidance only. All fuses, isolators and power cables must be rated and
installed in accordance with the prescribed IEC standards or local regulations – e.g. BS7671:2008.
Figure 3.5 shows details of the power terminal connections withing the UPS including connection sizes and recommended
tightening torque. This illustration shows that the UPS unit requires the following power cables:

3.10.5 External battery enclosures
The ST-40 and ST-60 cabinets have integral battery storage; however this is not possible with the ST-80, ST-120 and
ST-200 units due to the space required to house a battery of a suitable size. In the case of ST-80 and ST-120 systems the
battery is either contained in an external battery cabinet, or rack-mounted.
A range of bespoke battery enclosures designed specifically to suit individual site requirements can be supplied for the
ST-80 and ST-120 models – two typical examples are shown in Figure 3.12. In all cases, the battery enclosure is fitted
with suitably rated fused isolators which are connected to the battery connection terminals inside the PW8000DPA ST as
shown in Figure 3.5.
Note: DC fuses and cables are bespoke to the installation.

EXTERNAL BATTERY CABINET

Figure 3.13 External battery cabinet connection (ST-120 Cabinet shown)
Figure 3.13 shows typical methods for connecting the UPS cabinet (ST-120 in the example) to an external battery
installation. The top diagram illustrates connection for an ‘individual battery’ installation, and the lower diagram shows a
‘common battery’ installation.
A similar connection diagram for the ST-200 cabinet is shown in Figure 3.14. Note that the ST-200 cabinet only contains
connections for five external battery strings, however each connection is wired to the battery circuit breakers of two UPS
modules. Therefore where an ‘individual battery’ configuration is used with the ST-200 each battery is in fact connected to
2 UPS modules, rather than an individual module as is the case for the lower powered cabinets.

Operating modes

4.4.1 On-line (inverter) mode
When the UPS is operating in the on-line mode, the load is supplied
through the LINE 1 (RECTIFIER) and INVERTER. This provides the
highest degree of protection, especially in the event of a mains
disturbance or failure, and is always recommended if the critical load
(e.g. computer systems) will not tolerate even very brief supply
interruption.

LINE 2

BY PASS

LINE 1

INVERTER

LOAD

BATTERY

In the event of an inverter fault, or overload condition, the UPS
transfers the load to the bypass supply automatically and without
interruption, (transfer time = 0).

Figure 4.2 On-line mode

4.4.2 On-bypass (line-interactive) mode
In the on-bypass (line-interactive) mode the load is normally supplied
from the bypass mains (LINE 2) and the static BYPASS. In the event
of a bypass supply failure the load is automatically transferred to the
inverter within 3 to 5 msec – this is valid for single and parallel module
systems. The battery charger remains active in this mode.

LINE 2

BY PASS

LINE 1

INVERTER

LOAD

BATTERY

Although the on-bypass mode offers greater efficiency than the on-line
mode, it is recommended only if the load can tolerate interruptions of
up to 3-5 ms, which is the transfer time taken when switching from the
on-bypass mode to the on-line mode.

Figure 4.3 On-bypass mode

4.4.3 Maintenance bypass mode

MAINTENANCE Switch IA1
BYPASS

Each cabinet is fitted with a maintenance bypass switch (IA1)
which, when closed, connects the UPS module(s) output terminals
directly to the UPS bypass mains supply. This facility allows the
UPS system to be shut down for maintenance or repair whilst
maintaining the load on the raw (unprotected) bypass supply.

WARNING: ALL the UPS modules in a parallel
module system must be selected to on-bypass
mode before the maintenance bypass switch is
operated closed.

UPS Monitoring and automated control software

7.4.1 SNMP Card slots
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 an application running
within a standard web browser.
The PW8000DPA ST contains two SNMP slots; one is designed to house a Modem/Ethernet SNMP adapter card and the
other a Modem/GSM adapter. Alternatively, SNMP connectivity can also be implemented using an external SNMP adapter
connected to the UPS RS232 output (JD1).
An SNMP/Ethernet adapter contains an RJ-45 connector which allows it to be connected to the network using a standard
network cable. Once connected, the UPS-Management software agent, which is already installed in the SNMP adapter,
then monitors the UPS operating parameters and outputs its data in SNMP format to the connected network. In a multimodule UPS system the SNMP interface can communicate ‘system-wide’ data or data for an individual UPS module.
The SNMP adaptor requires a PC with terminal connections, and for normal operation at least one network connection
(Ethernet) is also required.

7.4.2 The importance of UPS management
The utility supply is inevitably unreliable every now and then; and assuring continuous power to all the facilities connected
to it can be a difficult task. The situation is further complicated if worldwide systems are managed via a Local Area
Network (LAN) or Wide Area Network (WAN).
However, by using the PW8000DPA ST UPS system in conjunction with purpose-designed network management tools, a
systems administrator can take measures to back-up data and prevent system errors or data loss even in the event of a
relatively long utility supply outage. In the case of an abnormal utility supply, suitable UPS management software will also
enable a system administrator to monitor all concerned networks from a central point and identify bottlenecks at an early
stage.
In spite of extensive system monitoring, if an administrator fails to intervene in a timely manner serious damage can still
occur. It is important therefore that the installed UPS software will react automatically in such a case and shut down the
supplied system in a safe and controlled manner. Uninterruptible Power Supplies Ltd considers it important to have a
complete solution for its UPS systems, and offers its customers a number of remote control and monitoring tools to
provide optimum protection.
Two monitoring system options are available for use with the PW8000DPA ST UPS system:
SNMP monitoring software
The SNMP adapter described above requires a PC with terminal connections and, for normal operation, at least one
Ethernet network connection. It also requires that the network operating system in use is SNMP-compatible.
Uninterruptible Power Supplies Ltd offer suitable monitoring software with SNMP functionality for NetWare, OS/2, all
Windows NT systems on INTEL and ALPHA network platforms.
WAVEMON UPS monitoring and control software
WAVEMON is designed to operate in conjunction with many of the systems supplied by Uninterruptible Power Supplies
Ltd and features both UPS monitoring and automatic UPS/server shutdown facilities.

7.4.3 WAVEMON Shutdown and Monitoring Software

Figure 7.4 Monitoring screen image

UPS454-01-02 PW8000DPA User Manual - (01-12-13)

7: Options

WAVEMON comprises a bespoke software package which is installed on a local PC and communicates with the UPS via
USB or a standard RS232 serial cable of up to 15m in length. It is only required when an SNMP card or adapter box is not
purchased.
The main features of WAVEMON are:
•
•
•
•
•
•
•
•
•
•

On-screen autonomy time/battery time countdown.
On-screen server log-off and shutdown procedure.
Time and date stamp event log.
Extensive logging of all UPS activity and power quality data.
Permits alarm warnings to be monitored remotely via email.
Scheduled UPS service mode and other systems status.
Graphical user interface for Windows-compatible platforms.
Automatic unattended local shutdown.
Special modules for MS-Office software to close and save open documents.
Compatible with all optional modules like UPSDIALER, SNMP adaptors, temperature sensors, etc.

7.4.4 Functional description
WAVEMON is a client/server software application for networks and local workstations. In general, it consists of two parts:
the server module of the UPS management software is UPSMAN, which communicates with the UPS via an RS232/USB
interface. Running as a background application, UPSMAN collects and interprets the messages received from the UPS
and places them at the disposal of the client module UPSMON, as well as any connected SNMP-based instrumentation
and control system.
If UPSMAN detects voltage variations or a power failure, it can execute various ‘system event’ routines, by means of
which, for example, the server is switched off or a warning/alarm is sent to the connected users. These ‘system event’
routines are a part of the management software and can be configured in to suit local application requirements.
The software of your PW8000DPA ST UPS unit can be integrated into a network in two ways:
1.

By the server which is supplied by the UPS itself and has been integrated into the network. In most cases this server
is used as a sub-agent and you only need the WAVEMON software (without an SNMP adapter). You will also need to
establish an RS232/USB connection between the UPS and computer/server.

In many cases the use of what is referred to as an ‘SNMP adapter’ is to be preferred in order to integrate the UPS into
the network. In this case up to 50 computers can be shut down in one RCCMD environment. RCCMD (remote console
command) is an additional software module that is used in order to execute a command (typically a shutdown
command) in a remote system.

7.4.5 Licensing
A licence is issued with every software serial number for use of what is known as the ‘UPS service’ on a single server in
connection with one UPS and an unlimited number of connected WINDOWS workstations. For operation with two or more
servers, a further licence is required for each additional server. In this case it is of no importance whether the UPS service
on these servers is active or whether the server was stopped by a remote UPS service. The same applies to the use of
RCCMD with the ‘remote send/receive’ modules for ‘multi-server shutdown’ under NT, UNIX and other operating systems.
The service programs are generally supplied as single licences. In order to use a single CD-ROM for several ‘multi-server
shut-down’ units you must acquire additional licence codes.

7.4.6 RCCMD Server shutdown
In order that remote shutdown of servers can take place, initiated by the SNMP card or WAVEMON software, further
licenses must be purchased. The license s for the RCCMD client (or listening) software that resides in each target server.
