General Description

2.1 General introduction

Congratulations on your purchase of the PW8000DPA ST S2 Uninterruptible Power Supply system.

2.1.1 Reliability and quality standards

Using a unique modular construction, the PW8000DPA ST S2 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 we use 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 provided in Chapter
8 of this manual.

2.1.2 Advanced design features

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 <4.5% THD(i) (10KW module) and <3% THD(i) (20KW module). This leads to a
more reliable overall system operation and savings in generator and transformer sizing, as winding losses 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
minimised 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

Decentralized Parallel Architecture (DPA)

The PW8000DPA ST S2 system features Decentralized Parallel Architecture (DPA) paralleling technology that provides
n+x redundancy without introducing a single-point-of-failure. Each power module is a fully functional, self-contained UPS
that includes an individual battery charger, power inverter, bypass, CPU, control panel and separate battery configuration;
making it a completely autonomous operating unit.

Flexible battery management

This equipment employs flexible battery charging management which avoids premature deterioration of battery life and
provides 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 (30-50 blocks of 12V; depending autonomy times).

TS_616_03 PW8000DPA ST S2 User Manual 4/4/18 3

2: General Description

• Wide UPS 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.

2.1.3 Model range

Figure 2.1 PW8000DPA ST S2 module configuration

The PW8000DPA ST S2 is a truly flexible system based on 10kW or 20kW UPS power modules which are assembled in a
range of purpose-designed, free-standing cabinets containing up to ten UPS modules. The cabinet is rated according to
the maximum number of 20kW modules that it can house – i.e. 40kW, 60kW, 80kW, 120kW and 200kW (see Figure 2.1).
The 40kW and 60kW cabinets also contain the UPS batteries but these must be located externally in the case of the
80kW, 120kW and 200kW models. A range of matching battery cabinets is available.

The illustrations in Figure 2.1 show the various cabinets fully populated; however each of the systems shown can operate
with as little as a single module fitted. Further power modules can be added to a vacant slot at a later time, without
needing to power-down the system or in any way disrupt the load. This ‘hot-swappable’ technology also allows individual
modules to be exchanged for testing or troubleshooting while the equipment is running without having to transfer the load
to the bypass supply – depending on prevailing system redundancy and load demand.

Key Point: All the modules fitted within a cabinet must be of the same rating – i.e. it is not possible to mix 10kW
and 20kW modules in the same parallel system.

2.2 Functional description of operation

This section describes:

• A block-diagram level description of the UPS module’s internal operation (see paragraph 2.2.1).

• The various operational states of a UPS power module (see paragraph 2.2.2).

• UPS system operation – ‘ON-LINE’ versus ‘OFF-LINE’ UPS system operation (see paragraph 2.2.3).

• Multi-module system operation and paralleling considerations (see paragraph 2.2.4).

2.2.1 UPS Power module internal operation

Figure 2.2 UPS module functional block diagram

Input and output contactors

The input contactor is electronically controlled by the UPS operating system and connects the mains input supply to the
rectifier block. This contactor operates during the module’s controlled start-up and shut down sequence and isolates the
rectifier from the mains following certain fault events.

Similarly, the output contactor allows control over the connection between the inverter and the UPS output (load). In
addition to being employed during the module’s start/stop sequence it is also used during load transfer between the
inverter and bypass supply and to isolate the UPS module following certain fault conditions.

Rectifier

The rectifier uses leading-edge switched-mode techniques which results in a module input power factor of almost unity
over its operating range (0.99 at full rated linear load). It converts the UPS mains input to a regulated DC power source
that can satisfy the inverter power demands (at 100% load) over an input voltage range of -20% to +15%. This wide input
voltage operating range means that the battery is not called upon during substantial power dips (brown outs), which in turn
maximises the battery life and availability.

DC Boost converter

The DC boost converter converts the DC voltage connected to its input, from either the rectifier or battery, into a regulated
DC bus suitable for powering the inverter.

Battery charger

A multi-stage battery charger, powered from the DC boost converter output, charges the battery whenever the input
supply is available and the rectifier/DC boost converter is turned on. The charger uses an intelligent charging profile to
obtain the best battery charge/discharge performance in order to optimise the battery life.

Inverter

The inverter converts the regulated DC voltage produced by the DC boost converter into a sinusoidal AC output voltage
suitable for connecting to the load. In addition to providing output voltage regulation, the inverter control logic also
provides various levels of overload protection, frequency regulation and synchronisation, and output voltage error
detection.

2: General Description

Static switch

The static switch provides a means of connecting the UPS module output to the bypass line – which is connected to the
UPS bypass input supply. Working in conjunction with the output contactor, the static switch control logic is used to
transfer the UPS output between the inverter and bypass supply without a break in the load supply.

Note: A brief load break will occur if transferring from bypass to inverter following a bypass supply failure, or if the bypass/

inverter are not synchronised when a transfer is demanded. (See ‘Off Line Mode’ in section 2.2.3).

Automatic battery switch

If the UPS mains input supply fails, the battery is automatically connected to the input of the DC boost converter by means
of an electronically controlled switch. This enables the inverter to continue its normal operation and maintain the UPS
output load supply from battery power.

2.2.2 UPS Power module operational states

UPS ON-INVERTER mode

Figure 2.3 illustrates the UPS ON-INVERTER
mode, which is considered the ‘normal’ mode of
operation:

• The rectifier and DC boost converter are
turned on to supply controlled DC power to
the inverter input.

• The battery charger charges the battery.

• The inverter converts the DC supplied by
the rectifier back into AC suitable for
connecting to the load.

• The output contactor is turned on to connect
the inverter output to the UPS output
terminals to provide the load with processed
power.

UPS ON-BATTERY mode

The UPS automatically changes to the ON­BATTERY mode if the mains input supply fails

during normal (ON-INVERTER) operation:

• The battery discharges through the DC
boost converter which regulates the battery
voltage at the level required by the inverter.

• The inverter converts the DC supplied by
the boost converter back into AC suitable
for connecting to the load.

• The output contactor is turned on to connect
the inverter output to the UPS output
terminals to provide the load with processed
power.

UPS ON-BYPASS mode

This mode can be selected by the operator as part
of the system operating procedure. It is also
entered following certain fault occurrences such as
a UPS output overload:

• The load is connected to the raw mains
input supply through the bypass arm of the
static switch.

• The rectifier and inverter remain powered
up and in operational readiness to be
brought into use.

• When operating in this mode the load is not
protected against any mains input supply
disturbances or loss.

2.2.3 UPS system operation

Summary of UPS module operating modes

UPS installations are generally categorised as being either ‘ON-LINE’ or ‘OFF-LINE/On stand-by’ systems; and the
PW8000DPA ST S2 can be configured to operate in either mode. The two systems are described below.

ON-LINE UPS system

An ‘ON-LINE’ system provides the highest degree of load protection, especially in the event of a mains supply disturbance
or complete failure, and we always recommended its use if the critical load (e.g. computer system) will not tolerate even a
very brief supply interruption.

When the PW8000DPA ST S2 is used as an ‘ON-LINE’ UPS it is configured to normally operate in the ON-INVERTER
mode, as shown in Figure 2.3. In the event of a mains supply failure, the UPS changes to its ON-BATTERY mode (Figure

2.4) without affecting its output supply – i.e the changeover to battery operation is totally transparent at the UPS output.
The UPS then continues to provide its rated output until the battery discharges to a low cut-off point, at which time the
UPS will attempt to switch to its ‘on bypass’ mode and, if the bypass is unavailable, then it will shut down in a controlled
manner. An audible and visual alarm will warn that the battery is discharging to enable the operator to take any necessary
intervention to protect the load integrity.

It is usual, especially in larger installations, to provide the UPS with an alternative input supply from a standby generator
which starts automatically following a mains supply failure; and where this is implemented the batteries discharge for a
short period only, until the generator comes on-line. This not only avoids the UPS shutting down due to discharged
batteries but also increases the battery life cycle.

If the UPS experiences an internal fault during ON-LINE operation, the inverter is turned off and the static switch transfers
the load to the bypass line (Figure 2.5) automatically and without interruption provided the inverter and bypass supplies
are synchronised. In the event of an output overload, the inverter can supply the load for a limited time, depending on the
overload severity, and if the permitted time is exceeded the load is transferred to bypass. The additional power available
from the bypass supply will attempt to clear the overload but if it persists it will ultimately rupture the bypass supply fuses.
If the overload condition clears while operating on bypass the load is re-transferred to the inverter and the UPS will return
to its normal ON-LINE mode of operation.

OFF-LINE (On stand-by) UPS system operation

When the PW8000DPA ST S2 is used as an ‘OFF-LINE’ UPS it is normally operated in its ON BYPASS mode (Figure 2.5)
with the load supplied via the bypass line. However the rectifier, DC boost converter and battery charger are still powered
up to maintain battery charging, and the inverter section is turned on and operating on standby.

In the event of a bypass supply failure, the inverter is immediately brought on line and the load is transferred from the
bypass line to the inverter by the static switch within 3 to 5 milliseconds. If the UPS bypass and mains inputs are
connected to separate sources and the mains supply is still live when the transfer takes place then the UPS will operate in
its ON-LINE mode (Figure 2.3). However, if these supplies are connected to a common source the UPS will immediately
revert to its ON-BATTERY mode (Figure 2.4).

2: General Description

When the bypass supply returns to normal, the load is re transferred back to the bypass line and the inverter returns to its
standby operation.

Operating in this mode is slightly more energy efficient than operating in the ON-LINE mode due to the reduced rectifier
and inverter losses during normal system operation; and it is sometimes referred to as the “ECO” (economy) mode.
However, this mode is recommended only if the connected load equipment can tolerate power interruptions of up to 3~5
ms during the transfer period.

Figure 2.6 Control panel mimic indications

2.2.4 Parallel system operation

The power output from all the modules fitted in a UPS cabinet are connected in parallel at the cabinet’s output terminals,
and the electronics built into each module’s control system ensures that:

• The UPS modules are always frequency-synchronised to each other – and to the bypass supply (when present).

• The UPS modules equally share the load current.

• The static bypass operation is synchronised such that, for example, if the operator selects ‘Bypass’ mode the static
switch in ALL the modules change over in unison.

It is also possible to connect the outputs from several UPS cabinets in parallel to increase the overall system capacity or
provide additional module redundancy – the maximum number of cabinets that can be paralleled is shown in the table
below.

When two or more cabinets are connected in parallel all the power modules within the cabinets are effectively paralleled
together – for example if three fully populated ST-120 cabinets are paralleled then the system effectively contains 18 fully
paralleled UPS power modules.

This requires the same degree of parallel control concerning synchronisation, load sharing, bypass switching etc. as
described for the modules operating in an individual cabinet; and in order to achieve this a parallel communication bus is
daisy chained between the cabinets as illustrated in Figure 2.7.

WARNING: The ON-LINE mode should always be used for critical load protection.

System expansion

Some UPS applications present a low initial power requirement which increases over time as the application grows; and it
is therefore essential that the installed UPS system can be expanded to meet the growing demand without compromising
the existing load. This requirement is well met with the ‘hot swappable’ feature of the PW8000DPA ST S2 UPS power
modules, whereby additional module(s) can be inserted into a vacant slot in an existing cabinet. If a system expansion
requires an additional cabinet the system will have to be shut down while the cabinet is installed.

Figure 2.7 Parallel system control

‘Capacity’ system

When a system is described as a ‘Capacity system’ it implies that the potential full load requires ALL the UPS power
modules to be operational – i.e. if one module trips off line due to a fault, the remaining modules will transfer the load to
the bypass supply and the load will no longer be protected against supply aberrations.

‘Redundant’ system

If a system is designed with module redundancy it must contain at least one UPS power module over and above that
necessary to power the applied load.

Key Point: When planning a multi-cabinet system, it is not necessary to fully populate one cabinet with UPS
modules before installing the next cabinet. For example, if it is known at the outset that the eventual load is likely
to exceed 300 KW it makes sense to install and cable-up four ST-80 cabinets and distribute the initially required
number of modules between them.

2: General Description

Using the example given above, four fully populated ST-80 cabinets (16 modules = 320kW) would present one redundant
module for a 300kW load. Under normal circumstances with all 16 power modules on-inverter they would each provide

18.75kW when full load is applied, but if one module fails or is taken off-line, the remaining 15 modules can sustain the
load by each providing their rated 20kW output. The ability to lose one module yet still supply the rated load with
processed, backed-up power significantly increases the overall system reliability.

Note: A parallel system operating with a redundant module is known as an ‘N+1’ system.

2.4 UPS Interface boards

Two interface boards are fitted in the lower part of the UPS cabinet, adjacent to the Maintenance Bypass switch. One is
the Customer Interface Board, which provides a means of connecting the UPS cabinet to a range of external monitoring
and control facilities. The other is the Parallel Interface Board which contains the connections used to control and monitor
the cabinets when connected as part of a parallel cabinet system.

2.4.1 Customer Interface Board

The Customer Interface Board, illustrated in Figure 2.13, provides a number of input/output interface connections that can
be used by the customer to facilitate external monitoring and control of the UPS system – e.g. as part as a building
management system (BMS).

The available interfaces include:

• Two smart slots – e.g. CS141

• RS485 interface via an RJ45 network connector (JR2)

• Relay operated dry-port alarm outputs for remote monitoring (X2)

• Dry-port inputs for customer remote control options (X1)

• RS232 computer interface for remote monitoring/control applications (JD1)

• USB port for computer monitoring applications

The dry-port connection details are provided in the Installation chapter of this manual (see Paragraph 3.7).

2.4.2 Parallel Interface Board

The Parallel Interface Board, illustrated in Figure 2.13, facilitates the connection of the parallel control bus cables between
the cabinets in a parallel system. The parallel bus cables are connected to a ‘Parallel Adapter’ board which is fitted to JD8.

Two terminal blocks are fitted to the Parallel Interface Board.

• Terminal block X1: The PW8000DPA ST has an optional ‘Synchronisation Feature’ which enables it to synchronise
to any other UPS system. This feature requires other factory-installed modifications and, when enabled, the ‘line’
supply of the external source is connected to X1 where it acts as a synchronisation reference.

• Terminal block X2: Is connected to the auxiliary contacts of an optionally installed external maintenance bypass
switch and/or external output isolator. This allows the UPS to detect the status of the external switch and react
accordingly. Details of the terminal block connections as shown in paragraph 3.8

In a parallel system, one cabinet acts as the ‘master’ cabinet and the remaining cabinets act as the slave. The master/
slave configuration is set by DIP switch S1-6.

Multidrop

The optional ‘Multidrop’ feature, which is available only in a parallel system, allows the Customer Interface Board in the
‘master’ cabinet to collect data/messages from the other system cabinets via the parallel control bus cables and Parallel
Interface Boards.

The received data is then processed at a centralised point on the ‘master’ Customer Interface Board and made available
to the user directly on the RS232 port (JD1). It is also transmitted to the CS141 card if inserted in the relevant slot.

Note that when the Multidrop feature is used the I/O facilities of Customer Interface Board in the ‘slave’ cabinets are all
disabled, but the Customer Interface Board fitted to the ‘master’ cabinet remains fully functional.

Key Point: The Parallel Interface Board is part of the factory-fitted ‘paralleling kit’ and is installed only in UPS
cabinets used in a parallel system.

Key Point: When the UPS cabinet is installed as part of a parallel system the Customer Interface Board I/O is
disabled in the ‘slave’ cabinets if the system ‘Multidrop’ application is enabled.

2.5.1 Power Management Display (PMD)

The 2 x 20 character LCD Power Management Display simplifies communication with the UPS and also provides UPS
monitoring information (see paragraph 2.6).

The menu driven LCD enables the operator to:

• Access the ‘event register’.

• Monitor the input and output voltage, current, frequency & power.

• Monitor the battery run time.

• Perform commands such as UPS start-up and shut-down and transfer the load between INVERTER and BYPASS.

• Access diagnostic and test facilities (service mode).

• Adjust the UPS configuration and operating parameters (service mode).

2.5.2 Mimic LED indicators

The mimic diagram LEDs indicate the operational status of the UPS power blocks, and change colour between Green and
Red (and OFF) to indicate the active power flow through the UPS.

• LINE 1 (rectifier) and LINE 2 (bypass) indicate the availability of the UPS mains and bypass input power supplies.

• INVERTER and BYPASS, when green, indicates which of the two sources is providing the critical load power.

• The BATTERY LED indicator flashes when the battery is supplying the load – e.g. following a mains failure.

• The ALARM LED is a visual indication of an internal or external alarm condition. When activated, it is accompanied
by an audible warning.

2.7 Optional system control panel

The system control panel is an optional
component which is fitted to one UPS cabinet,
usually the ‘master’ UPS, in a parallel cabinet
system.

It contains a microprocessor-based TFT touch­screen display which enables the operator to
monitor the status of the overall UPS system as
well as each individual UPS module. It also
allows the operator to transfer the load between
the inverter and bypass. All other UPS module­level commands must be performed from an
individual module’s control panel. By having
both control panels in place, working at ‘module’
and ‘system’ level, the UPS offers enhanced
user friendliness without compromising on
robustness.

Using the touch-screen, the operator can:

• check system’s operational status and
measurements

• execute system-level commands

• monitor the power flow through the UPS
system

• check alarm and events history

• silence alarms

• adjust programmable parameters

• view the battery status

The display turns on automatically when the first UPS power module is energised; and after a few seconds of initialisation
it displays the default module mimic screen shown in Figure 2.16.

Depending on the method of shipping, the UPS is packed in a cardboard or wooden container designed to protect it from
mechanical and environmental damage. Further protection is provided by wrapping the equipment with a plastic sheet.

Before you accept the shipment, ensure that the received UPS packages correspond to the description indicated in the
delivery document. Note that some ordered optional equipment packages might be shipped inside the UPS cabinet.

When you receive the UPS, carefully examine the packing container for signs of physical damage. The external 'Tip&Tel'
(“FRAGILE” and “ARROW”) indicators should be intact if the equipment has been transported in an upright position.

3.2.1 Reporting transpiration damage

If the 'Tip&Tel' indicators are ruptured or there are other signs of suspected transportation damage you must inform the
carrier and Uninterruptible Power Supplies Ltd. immediately.

Other claims for shipping damage must be filed immediately where found, and the carrier must be informed of ALL claims
within seven days of receipt of the equipment. If the equipment is to be stored for longer than seven days before it is
installed, you should unpack it and inspect it for signs of internal damage before you put in storage. Note that some
optional equipment packages might be shipped inside the UPS cabinet and these too should be checked for damage.

If the equipment is damaged you should store the packing materials for further investigation

Key Point: If you are installing an external battery cabinet supplied by Uninterruptible Power Supplies Ltd. you
should refer to the manual that is supplied with the cabinet for installation instructions.

WARNING: All the operations described in this chapter must be supervised by suitably qualified personnel and
all aspects of the electrical installation must be carried out by an authorised electrician.
Uninterruptible Power Supplies Ltd. will take no responsibility for any personal injury or material damage
caused by incorrect cabling or operation, or activities which are not carried out in strict accordance with the
instructions contained in this manual.

WARNING: Once the UPS equipment is installed it must be commissioned by an engineer approved by
Uninterruptible Power Supplies Ltd. or one of its service agents before it is powered-up. Uninterruptible Power
Supplies Ltd. will take no responsibility for any personal injury or material damage caused by the application of
electrical power to this equipment before it has been fully commissioned.

CAUTION: Observe the following precautions when off-loading and moving the UPS:

• Always keep the packages in an upright position.

• Do not drop the equipment.

• Do not sta ck the pallets.

WARNING: If the Tip&Tell indicators indicate that the UPS has been tilted in transit DO NOT connect the

3.2.2 Local site transportation

When you transport the UPS equipment after it has been off-loaded (for example, for storage or moving to the installation
location) please observe the following precautions.

3.2.3 Storage

If you plan to store the UPS prior to its installation it should be kept it in a clean, dry environment with a temperature
between -25°C to +70°C and RH <90%, and preferably in its shipping packaging. If the storage period is likely to exceed
seven days the packaging should be removed and the UPS inspected for internal/external shipping damage before it is
placed into storage. If there is no apparent damage you should refit the packaging or cover the UPS with a dust-cover to
prevent the ingress of dust and dirt.

As standard, the UPS batteries can be housed within the UPS cabinet (40kVA and 60kVA models) or within an external
battery cabinet or rack-mounted (80kVA, 120KW, 200kVA models). In the case of internally-mounted batteries, the
batteries can be shipped already fitted within a cabinet; alternatively, batteries intended for external rack-mounting will be
shipped in a separate package. which should be stored under the environmental conditions stipulated above.

3.2.4 Unpacking

If the shipment is received in good order (i.e. the ‘tip & tell’ “FRAGILE” and “ARROW” indicators on the packing container
are intact) then unpack the UPS as follows:

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 package.

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

3. Remove the plastic sheeting covering the UPS.

4. Remove the UPS from the pallet.

5. Retain the packaging materials for future shipment of the UPS.

6. Examine the UPS for any sign of damage and notify your supplier immediately if damage is apparent.

7. Open the cabinet door and verify that the UPS rating specifications on the nameplate located inside the door match
the order specification.

8. Remove any accessories packages that are shipped inside the cabinet.

9. Remove any internal protective packaging.

10. Ensure that all the UPS modules are securely fitted in their compartments. Ensure that a protection cover is fitted to
the front of any empty UPS compartments.

CAUTION: Local transportation:

• W hen moving the UPS cabinet using a forklift or pallet jack, insert th e lifting equipment forks into the
front and rear shipping brackets to lift the cabinet securely and prevent it from toppling over.

• Do not at any time tilt the cabinet by more than 10° from vertical.

WARNING: Potential dangers:

• If the equipment cabi net is tilted by more than 10° it could cause i nternal damage. If tilting occurs d o
not connect the UPS to the mains electrical supply.

• The weight cabin et can cause serious personal injury and/or structural damage to the surrounding
area if dropped in transit. Always take extreme care when moving the equipment.

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

3.2.5 Batteries

If the batteries are shipped in a separate package they should remain in their packing until required by the Uninterruptible
Power Supplies Ltd. service engineer when the system is commissioned.

Battery life depends very much on the ambient temperature, and optimum battery life will be obtained if the batteries are
stored and operated at a temperature of 20°C.

3.3 Positioning

3.3.1 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 operating environment.

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

2. 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.

3. The UPS cabinet requires space to bottom/front, top and back to enable cooling airflow, as shown in figures 3.1 and

3.2. The ST200 battery circuit breaker is located on the back of the cabinet and suitable access must be provided to
operate the breaker. Two alternative installation layouts are shown in figure 3.2.

4. A minimum clearance of 200mm must be provided at the back of the cabinet to provide adequate ventilation. A
clearance of 400mm should also be provided at the top of the cabinet if there is in insufficient route at the back of the
cabinet to dissipate the cooling airflow.

5. All parts of the UPS required for maintenance, servicing and user operation are accessible from the front. Reserve a
minimum of 1000mm space at the front of the UPS cabinet. Note also that the cabinet right-hand door must be
opened by 115° in order to remove/fit the UPS power modules so the right-hand side of the cabinet cannot be
positioned directly against a projecting wall.

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

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

8. In summary, the UPS should be located where:

a) Humidity (< 90%) and temperature is ideally 20°C.
b) Fire protection standards are respected.
c) Cabling can be performed easily.
d) A minimum 1000mm front accessibility is available for service or periodic maintenance.
e) Adequate cooling air flow is available.
f) 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.

3.3.2 Clearances

Figures 3.1 and 3.2 illustrates the required clearances that must be provided around the UPS and external battery
cabinet. All parts of the UPS that require access for maintenance, servicing and user operation are accessible from the
front of the cabinet. Ensure that all ventilation ports are kept free of obstruction.

CAUTION: The UPS batteries must ALWAYS be installed by the commissioning engineer.

WARNING: If the UPS is delivered without batteries, Uninterruptible Power Supplies Ltd. will not accept
responsibility for any damage or malfunctioning caused to the UPS by the incorrect storage, installation or
connection of batteries carried out by third parties.

3.4 UPS Power Cabling (preparation and planning)

3.4.1 General requirements

It is the customer’s responsibility to design the UPS supply and distribution circuits, and provide all the external fuses,
isolators and cables required to connect the UPS input and output power supplies and battery cabinet. The information in
this section should assist in the planning and preparation of the UPS power cabling.

The UPS rectifier supply and bypass supply should be connected to the utility mains through a LV-switchgear panel and
protected by a circuit breaker or fuse to provide overload protection and a means of isolating the UPS from the mains
supply. Similarly, the UPS output should be connected to the load equipment via a suitably fused switchgear panel.

The UPS can be wired with a ‘single feed’ input (standard) or with a ‘dual feed’ input, whereby the UPS bypass circuit is

connected to a dedicated mains ‘bypass’ supply (See Figure 3.3).

3.4.2 Cable sizing

The table below shows the maximum UPS input and output current together with the UPS cable termination details. This
is provided to assist the customer in selecting the appropriate power cables and external switchgear. Details of the UPS

power connections are shown in Figure 3.5 and Figure 3.6.

Notes:

1. The UPS must be installed to prescribed IEC or local regulations (e.g. BS7671:2008).

2. Where external batteries are used, DC Cables and Battery fuses are bespoke to the installation.

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.

3.4.3 Parallel cabinet cabling recommendations

In order to achieve equal load sharing between the various UPS cabinets in a multi-cabinet installation, the input cables
from the mains switchgear panel to each UPS cabinet should be of equal length. Similarly the UPS output cables to the
switchgear panel should be of approximate equal length.

3.4.4 External maintenance bypass

An external maintenance bypass is a required part of a multi-cabinet
system but is optional in the case of a single cabinet installation.

The external bypass is bespoke to the installation but generally
comprises three isolators rated to carry the full system load and
connected in a similar fashion to that shown in Figure 3.8. Depending
on size and location, the isolators may be installed in a dedicated
Maintenance Bypass cabinet or included in an existing (or dedicated)
switchgear panel.

Uninterruptible Power Supplies Ltd. can provide a range of external
maintenance bypass solutions to suit all of its UPS systems.

Note: When starting the UPS system we advise that the load is initially

turned on while the system is operating on maintenance bypass in
order to handle any large inrush currents that might occur.

Single UPS cabinet installation

An external maintenance bypass facility is not essential for a single
cabinet installation as the internal maintenance bypass switch (IA1) is
fully rated and can be used to connect the load directly to the raw UPS
bypass mains supply. However, when operating via the internal
maintenance bypass switch (IA1) the UPS input/bypass mains supply
must be permanently available, so it is not possible to isolate these
supplies from the cabinet (or UPS modules) while the internal
maintenance bypass is in use.

This situation is overcome by the addition of an external maintenance
bypass circuit, similar to that shown in Figure 3.8, which can supply the
load through the external BYPASS switch while allowing the UPS
cabinet input and output to be totally isolated by opening the external
INPUT and OUTPUT switches.

Parallel UPS cabinet installation

If two (or more) UPS cabinets are connected as a parallel system each
one still contains the internal maintenance bypass switch (IA1).
However, the switch is only rated for the specified cabinet output and
is not designed to switch the potential full system load.

An external maintenance bypass facility containing a ‘system rated’
bypass switch is therefore an essential part of a parallel cabinet
system as it allows the full load to be switched between the system and maintenance bypass. It also allows the modules’
input and bypass mains supplies to be isolated as described above for the single UPS cabinet system.

Key Point: When operating a parallel system ALWAYS use the external maintenance bypass facility. Do not
operate the internal maintenance bypass switch (IA1).

2. Connect the UPS rectifier supply cables to terminals 1L1, 1L2, 1L3 and 1N on the UPS terminal block, ensuring
correct (clockwise) phase rotation.

3. Connect the UPS bypass supply cables to terminals 2L1, 2L2, 2L3 and 2N on the UPS terminal block, ensuring
correct (clockwise) phase rotation.

4. Secure the cables to the fixing rail located under the UPS power terminals.

Note: The UPS commissioning engineer will configure the UPS control system for a dual input operation at the time of

commissioning.

3.5.4 Preparing the output power cabling

Before you connect the UPS output cables:

1. Ensure that the potential full load does not exceed the output power rating (OUTPUT POWER) on the UPS
nameplate.

2. Ensure the output circuit breakers are correctly sized with respect to the load rating and associated cabling.

3. Check that the output load circuit breakers comply with the prescribed IEC Standards (e.g. BS7671:2008) or local
regulations.
It is recommended that a separate switchgear panel is provided for the load and that the maximum total load rating
and the load rating of the individual load sockets are indicated on the panel.

3.5.5 Connecting the UPS output cables

1. Connect the protective earth cable from the output (load) switchgear panel to the UPS output protective earth (PE)
terminal, as shown in Figure 3.9.

2. Connect the UPS output supply cables to terminals 3L1, 3L2, 3L3 and 3N on the UPS main terminal block. Ensure
correct (clockwise) phase rotation.

3. Secure the cables to the fixing rail located under the UPS power terminals.

4. Ensure the output cables are connected to the correct power terminals on the output (load) switchgear panel.

CAUTION: The input Neutral cable must ALWAYS be connected.

CAUTION: If the rectifier and bypass inputs are fed from the same three-phase power source there is no

need to connect a separate bypass neutral if the two neutral input terminals are linked at the UPS input
connections. If the bypass supply is derived from a different three-phase power source then the bypass
neutral must be permanently connected and unswitched.

WARNING: Do not close the UPS external power circuit breakers. Once the electrical installation is
completed the initial UPS start-up must be performed by qualified commissioning engineer authorised by the
manufacturer.

3.6 Battery configuration

3.6.1 Battery configuration options

When considering the PW8000DPA ST S2 battery installation, several battery configurations are possible to meet the
required load power and battery autonomy time. These factors are determined by:

• The number of battery blocks connected to the battery string, and the number of connected strings

• The battery block capacity (A/hr)

• The method of connecting the battery to the UPS power modules – i.e. either ‘Common’ or ‘Individual’ battery.

See the examples shown in the following diagrams.

3.6.2 Battery cabling

Figure 3.10 Battery connections (ST-80 cabinet shown)

In the ST-80, ST-120 and ST-200 models the external batteries are connected to terminal blocks mounted on the left hand
side of the power connection rail. The cables at the top of the terminal blocks are connected to the battery isolators
associated with each individual UPS power module and the cables at the bottom of the terminal blocks are connected to
the external battery cabinet(s).

The example in Figure 3.10 illustrates the ST-80 cabinet which has four terminal block connections, one for each UPS
power module. Each battery string is shown to have three connections annotated ‘+,’ ‘N’ and ‘–’. The ‘N’ connection is
effectively taken to the centre of the battery string.

IMPORTANT NOTE

High voltage battery strings can be extremely dangerous and should not be installed by the
customer’s installation team. The batteries must be installed and connected to the UPS by an
Uninterruptible Power Supplies Ltd. service engineer.

It is the customer’s responsibility to provide appropriate containment for the DC power cables
between the UPS cabinet and battery cabinet where necessary – e.g. cable trays or trunking. The
battery cabling details shown below are provided for reference only.

3: Installation

Note: In the case of the ST-200 each external battery is connected to two UPS power modules so only five sets of battery

connections are provided to cater for the (up to) ten modules. However each UPS power module has an individual battery
isolator located on the back of the UPS Cabinet.

Common battery configuration

Where a ‘common battery’ configuration is implemented, all the UPS modules are fed by a common battery source –
which may comprise a number of parallel battery strings. Where this type of installation is used the ‘common battery’ links
must fitted to the battery connection terminal blocks as shown in the left-hand diagram of Figure 3.10. These links must be
removed for ‘individual battery’ configuration.

3.6.3 Internal battery configuration for ST-40 and ST-60 cabinets

The ST-40 and ST-60 cabinets are designed to house 80 and 240 internal 12V (7/9Ah) battery blocks respectively.

Different battery configurations are shown below.

For details of the battery connections see Figure 3.5 and Figure 3.10.

Important notes:

• When the cabinets are populated with 10KW UPS modules the 12V batteries can be connected in strings of 30-50

(even numbers only), depending the power sourced on the output.

• When the cabinets are populated with 20KW UPS modules the 12V batteries can be connected in strings of 40-50

(even numbers only), depending the power sourced on the output.

• The commissioning engineer will program the correct number of battery blocks into the UPS control system using

the control panel Service-Set-Up menu when the system is commissioned.

3.7 Customer Interface Board

The Customer Interface Board is described in the General Description chapter, section 2.4, with some of its common
applications described in detail in the Options chapter. This section deals with the connection of the dry port interface
connections taken to terminal blocks X1 and X2 which may be connected at this stage of the installation procedure.

All the on-board relays connected to these terminal blocks are rated at 60VAC / 8A and the Phoenix terminals are rated to
take cable of 0.5 mm².

Input interfaces connected to terminal block X1

Note that the connection of Remote Shut down, Generator Operation and Customers specials are described in Chapter 7.

.

Output interfaces connected to terminal block X2

CAUTION: The Customer Interface Board contain several DIP switches and jumper links which must be
configured by the commissioning engineer. Once set, DO NOT touch.

Key Point: When the UPS cabinet is installed as part of a parallel system the Customer Interface Board I/O is
disabled in the ‘slave’ cabinets if the system ‘Multidrop’ application is enabled. Under such circumstances the
required interface connections should be made to the board fitted in the ‘master’ module only – see section 2.4.

3.8 Parallel-cabinet control and configuration

When several UPS cabinets are connected as a parallel system the modules’ electronic control system communicate with
each other by means of a parallel control bus which is connected between each cabinet and facilitates various system
control functions such as load sharing, frequency synchronisation, and synchronised load transfer (see section 2.4.2). The
parallel control bus comprises a 25-way cable which is connected to an adapter board which is fitted to the Parallel
Interface Board.

Note: The inter-cabinet Multidrop data connection is also incorporated in the 25-way parallel control bus cable.

The parallel adapter boards and cables are shipped as a ‘paralleling kit’ and must be fitted by the Uninterruptible Power
Supplies Ltd. commissioning engineer

Once the parallel bus cables are fitted, each cabinet is configured by means of a DIP switch to define its position in the
parallel system – one UPS cabinet is configured to act as a ‘master’ with the remaining cabinets acting as ‘slaves.’ If the

Operation

4.1 Introduction

4.1.1 Commissioning

The PW8000DPA ST S2 UPS is a high quality, complex electronic system which must be commissioned by an authorised
Uninterruptible Power Supplies Ltd engineer before it is put into use.

The commissioning engineer will:

• connect the UPS batteries

• check the UPS electrical and mechanical installation, and operating environment

• check the UPS configuration settings

• check the installation and operation of any optional equipment

• perform a controlled UPS start-up

• fully test the system for correct operation

• provide customer operator training and equipment handover

4.1.2 Operating procedure summary

Under normal circumstances all the UPS modules are turned on and operating in their ‘on-inverter’ mode. If one module
fails in a redundant module system the faulty module shuts down but the remaining module(s) continue to operate
normally and provide protected load power.

If a UPS module fails in a capacity (or single module) system, the load immediately transfers to the static bypass supply (in
all modules) and is supplied with unprotected bypass mains power.

A parallel-cabinet UPS system requires the installation of an external maintenance bypass circuit which wraps around the
entire UPS system – an external maintenance bypass is optional in a single cabinet installation. The external maintenance
bypass is bespoke to the installation and installed in a separate ‘Maintenance Bypass’ cabinet or switchgear panel (see
paragraph 3.4.4). If an external maintenance bypass is installed you should familiarise yourself with its operating
procedures before using the UPS operating procedures contained in this chapter.

Note: All the switches and control panel operations mentioned in this chapter are identified and described in chapter 2.

The commissioning engineer will hand-over the system in a fully working condition with all the UPS modules turned on and
operating in the ‘on-inverter’ mode (or ECO mode, if appropriate).

WARNING: Uninterruptible Power Supplies Ltd. will not accept responsibility for the equipment or the safety of
any personnel if the UPS system is operated before it has been fully commissioned.
The manufacturer's warranty will be invalidated if power is applied to any part of the UPS system before it has
been fully commissioned and handed over to the customer.

CAUTION: In a multi-cabinet system always use the external maintenance bypass facility. DO NOT operate
the cabinets’ internal maintenance bypass switch (IA1).

TS_616_03 PW8000DPA ST S2 User Manual 4/4/18 51

4: Operation

4.1.3 General warnings

4.2 Operating instructions

Under normal operating conditions all the UPS power modules are running and operating in the on-inverter mode.

This chapter contains the following procedures:

• How to start the UPS system from a fully powered-down condition (See paragraph 4.3).

• How to start the UPS system when it is initially operating on the maintenance bypass (See paragraph 4.4).

• How to transfer the load to the maintenance bypass and stop the system – (See paragraph 4.5).

• How to shut down the entire UPS system (See paragraph 4.6).

4.3 How to start the UPS system from a fully powered-down condition

In order to reduce the possible effects of high inrush currents that might occur when the load is initially turned on, we
recommend that you power-up the load when the UPS system is operating on maintenance bypass, as described in this
procedure. In a parallel-cabinet system the maintenance bypass switch is external to the UPS cabinets and bespoke to
the installation. You should familiarise yourself with the operation of the external maintenance bypass circuit operation
before using this procedure.

Initial conditions:

This procedure assumes the following initial conditions.

• The UPS maintenance bypass switch is open.

• The UPS input mains isolator (and bypass mains isolator in a split bypass system) at the input switchgear panel is

open.

• The UPS output isolator at the switchgear panel is open.

WARNING: The procedures given below must be performed by a trained operator.

WARNING: When the UPS system is operating on BYPASS or via the MAINTENANCE BYPASS SWITCH, the

load supply is unprotected if the bypass mains supply fails. It is essential that the load user is informed of this
possibility before you select these operating modes.

WARNING: When the UPS is shut down, power is still applied to the UPS modules and the cabinet input/
bypass terminals unless the input/bypass mains is isolated at the external UPS input switchgear panel. In a
single cabinet installation it is not permissible to turn off the external input/bypass mains supply when the load
is connected via the internal maintenance bypass switch (IA1) as this will remove the load power.

IMPORTANT NOTE

In the following procedures, all references to the ‘Maintenance Bypass Switch’ apply to the internal
maintenance bypass switch (IA1) in the case of a single cabinet if it is not connected to an external
maintenance bypass facility. If an external maintenance bypass facility is installed (standard in a
parallel-cabinet system) they apply to the maintenance bypass switch in the external facility.

CAUTION: In a multi-cabinet system always use the external maintenance bypass facility. DO NOT operate
the internal cabinet maintenance bypass switches (IA1).

4.4 How to start the UPS system from the maintenance bypass

Initial conditions:

This procedure assumes the following initial conditions.

• The load is connected to the maintenance bypass supply.

• The UPS input mains isolator (and bypass isolator in a split bypass system) at the input switchgear panel is closed

(see the IMPORTANT NOTE above).

• The UPS output isolator at the switchgear panel is closed.

• The load equipment is turned on and receiving power through the UPS maintenance bypass.

Powering up the UPS system:

1. If the UPS system is operating on maintenance bypass it can be powered up using the procedure described in

Paragraph 4.3 (How to start the UPS system from a fully powered-down condition) beginning at step 7.

IMPORTANT NOTE

If the UPS system uses an external maintenance bypass circuit it might be configured such that the
UPS cabinet input/bypass supply can be turned OFF when the load is connected through the
external bypass. Where this is the case, all power is removed from the cabinet and the UPS
modules will be completely powered-down, with no indications on the module control panels.

The UPS cabinet input/bypass supply must be restored before you use the following procedure.

Maintenance

5.1 Introduction

5.2 User responsibilities

There are no user-serviceable parts contained within the UPS so the maintenance requirements to be carried out by the
user are minimal, beyond ensuring that the local environment in which the UPS is operating is kept cool (20ºC), clean and
dust free.

5.3 Scheduled maintenance

It is essential that the UPS system and batteries receive regular preventative maintenance to maximise both the useful
working life and system reliability. When the UPS is commissioned, the commissioning engineer will attach a service
record book to the front of the UPS which will be used to log the full service history of the UPS.

It is recommended that the UPS system is maintained every six months by a Uninterruptible Power Supplies Ltd. trained
engineer who will complete the following:

5.3.1 Preventative maintenance inspection

Preventative maintenance inspections form an integral part of all Extended Warranty Agreements (maintenance contracts)
offered by Uninterruptible Power Supplies Ltd.

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

• Site environmental conditions

• Integrity of electrical installation

• Cooling airflow

• Load characteristics

• Integrity of alarm and monitoring systems

• Operation of all installed options

• Check all event logs

5.3.2 System calibration

To ensure optimum UPS operation and efficient load protection we recommended that the system’s operating parameters
are checked and recalibrated where necessary.

During a system calibration a trained Uninterruptible Power Supplies engineer will check:

• Rectifier operation and calibration

• Inverter operation and calibration

• Bypass operation

• Battery status and battery test

WARNING: All the operations described in this chapter must be performed by suitably qualified personnel.

WARNING: Preventative maintenance inspections involve working inside the UPS which contains

hazardous AC and DC voltages, and should be performed only by an authorised engineer who has been
trained by Uninterruptible Power Supplies Ltd.

TS_616_03 PW8000DPA ST S2 User Manual 4/4/18 57

5: Maintenance

5.3.3 Battery maintenance and testing

The batteries should be checked and tested by a trained Uninterruptible Power Supplies engineer 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.

Battery disposal and recycling

Batteries contain dangerous substances that can harm the environment if disposed of carelessly. If you have reason to
change the batteries, always consult with your local environmental waste disposal organisations to obtain the
recommended disposal and recycling information.

Troubleshooting

6.1 Alarms

If an alarm condition occurs, the red ALARM LED will illuminate on the module control panel and the audible alarm will
sound. In this case proceed as follows:

1. Silence the audible alarm by pressing the RESET button.

2. Identify the cause of the alarm by viewing the events register in the main menu (See paragraph 2.6.3).

3. In case of doubt, contact your nearest service agent or call Uninterruptible Power Supplies Ltd. on 0800 731 3269.

6.2 Menu, Commands, Event Log, Measurements,

A detailed description of the Menu, Commands, Event Log and Measurements that can be operated and displayed on the
LCD panel can be found in paragraph 2.6.

6.3 Fault identification, rectification messages and alarms

IMPORTANT NOTE

Certain alarm conditions may ‘latch-on’ even after the cause of the alarm is no longer present. For
example, if there is a brief mains failure during unattended operation the MAINS RECT FAULT alarm
will activate and it may still indicate a fault condition even after the mains supply has returned to
normal.

If any of the following alarms appear, the first action to take is to attempt to RESET it.

• MAINS RECT FAULT

• MAINS BYP FAULT

• BYPASS IS OK

• BYPASS IS NOT OK

If the alarm resets then it was probably caused by a transient condition and is no longer present; the
UPS responded correctly and no further action is required. However, if it is not possible to reset the
alarm, investigative action is necessary which may require assistance from the UPS Service
department.

Alarm Condition Meaning Suggested Solution

MAINS RECT. FAULT Mains power supply is outside prescribed tolerance. The input power to UPS is too low or missing.

If site power appears to be OK, check the
input circuit breakers etc. supplying the UPS.

MAINS BYP FAULT Mains power supply is outside prescribed tolerance. The input power to UPS is high/low or missing.

If site power appears to be OK, check the
input circuit breakers etc. supplying the UPS.

OUTPUT SHORT There is a short circuit at the UPS output. Check all output connections and repair as

required.

We recommend that your UPS is protected by an Extended Warranty Agreement – see Chapter 2 for details. These
agreements assist us in caring for your UPS correctly, ensuring that it is well maintained and attended to promptly should
any problems occur.

OVERLOAD Load exceeds the UPS rated power. Identify which piece of equipment is causing

the overload and remove it from the UPS.
Do not connect laser printers, photocopiers,
electric heaters, kettles etc. to the UPS.

TEMPERATURE HIGH UPS temperature has exceeded the allowed value. Check the ambient temperature of the UPS is

less than 40°C.
If the ambient temperature is normal call the
authorised service centre for assistance.

INV. PHASE FAULT Inverter is faulty. Call the authorised service centre for

assistance.

BATTERY IN

Options

7.1 Introduction

The PW8000DPA ST S2 UPS has the following available options:

• Remote shut down facilities

• Generator ON facilities

• 1 x Customer-input function (customer defined)

• RCCMD shut down and management software

• SNMP Card for network management and remote monitoring

• Modem/Ethernet interface for PowerReporter™ management software

7.2 Remote shut down

The remote shut down facility takes the form of a
normally-open contact which closes to activate the
UPS stop shut down sequence.

On leaving the factory the ‘remote shut down’
function is disabled and it must be enabled, if
required, by setting a hardware code on the SETUP
SERVICE menu. This should be carried out by the
commissioning engineer. If you require this feature
to be enabled after the system is commissioned
please contact your distributor.

The remote shut down facility is connected to
terminal port X1/7 – X1/8 on the communication
card located on the PW8000DPA ST S2 front
frame.

In order to allow the safe removal, maintenance or
testing of the remote emergency stop device,
without affecting the UPS operation, it is
recommended that a terminal block with linking
facilities is installed between the UPS and the
remote shut down mechanism.

1. Use a screened cable with a single pair
(0.5 mm²) and maximum length of 100 m.

2. Connect the cable as shown in Figure 7.1.

CAUTION: When the UPS cabinet is installed as part of a parallel system the Customer Interface Board I/O is
disabled in the ‘slave’ cabinets if the system ‘Multidrop’ application is enabled. Under such circumstances the
required interface connections should be made to the board fitted in the ‘master’ module only – see section 2.4.

WARNING: The remote shut down facility should not be used as an ‘Emergency Stop’ because it will not turn
off the UPS, or isolate the critical load, when the UPS is operating on its maintenance bypass.

7.3 Generator ON facilities

The Generator ON facility must use a normally­open contact which closes to signal that a
generator is running and supplying the UPS
input power. When this function is enabled it
can be set to inhibit the battery charger to
reduce the power drawn from the generator
and/or inhibit the bypass to prevent the load
being transferred to the generator.

On leaving the factory the ‘generator ON’
function is disabled and it must be enabled, if
required, by setting a hardware code on the
SETUP SERVICE menu. This should be carried
out by the commissioning engineer. If you
require this feature to be enabled after the
system is commissioned please contact your
distributor.

1. Use a screened cable with a single pair
(0.5 mm²) and maximum length of 100 m.

2. Connect the cable as shown in Figure 7.2.

7.4 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 S2 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. In a multi-module UPS system the SNMP interface can communicate
‘system-wide’ data or data for an individual UPS module.

The SNMP card enables event/alarm emails, server shut down (with optional licenses) and other tasks. The SNMP card
can also be integrated with BMS software over a local area network (LAN) for SNMP or Modbus information over IP. An
optional card enables Modbus communication over RS485.

7.5 Remote interlock (for external maintenance bypass only)

A key-operated remote interlock facility can be
installed to prevent the external bypass switch from
being closed before the UPS has been switched to
the static bypass. This avoids the possibility of the
UPS being damaged due to the closure of the
external bypass switch while the UPS is operating
on inverter.

The remote interlock circuit requires the
maintenance bypass key-switch to be connected to
auxiliary contacts of the internal maintenance
bypass switch (IA1), as shown. This must be
connected and functionally tested by a UPS Limited
engineer.

This can be part of a wider interlocking system
within the distribution design.
