2: General Description

2.2 PowerWave 9000 Model range

The PowerWave 9000 UPS is based on a range of 30kVA to 50kVA plug-in power modules fitted into one of three
purpose-designed cabinets. Each power module is a self-contained UPS comprising a rectifier, battery charger, inverter
and static switch; and when two or more modules are fitted into a cabinet they effectively operate as a parallel UPS
system. The available cabinets can contain up to one, three or five power modules as shown below in Figure 2.1.

The PowerWave 9000 cabinets are identified as CLASSIC DPA-50, TRIPLE DPA-150 and UPGRADE DPA-250 – where
the model number represents the maximum kVA output available when the cabinet is fully populated with 50 kVA power
modules. Figure 2.1 shows that the DPA-50 and DPA-150 cabinets include shelves for housing the UPS batteries;
however the DPA-250 cabinet has no internal battery mounting facilities and requires an external battery cabinet. A range
of matching battery cabinets is available which are installed adjacent to the UPS cabinet in the majority of installations. An
additional (external) battery cabinet can also be connected to the DPA-50 and DPA-150 models to extended the overall
system autonomy time if desired.

Figure 2.1 PowerWave 9000 Cabinets (frames)

Figure 2.2 PowerWave 9000 UPS Power Modules

Key Point: All the modules fitted within a cabinet must be of the same rating – for example, it is not possible to

mix 30kVA and 50kVA modules in the same cabinet.

2.2.1 Advanced design features

Hot-swappable modules

In a redundant module system the unique ‘hot-swappable’ feature enables a UPS power module to be inserted or

removed from its cabinet whilst it is still powered (hot) without having to shut down the load or transfer it to the bypass

supply.

Note: In a non-redundant system the load will unavoidably have to be transferred to the bypass supply wh ile a mo dule i s

shut down or removed from the system.

Advanced booster technology

The UPS power 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 less than 3% THD(i). This leads to a more reliable system operation together
with savings in generator and transformer sizing due to reduced winding losses; and also means that traditional input
harmonic filters (still used by some systems) are not required.

The high power factor presented by the UPS on the incoming mains supply minimises cabling and fusing costs due to the
reduced reactive power consumption which, together with the accompanying low harmonic currents, provides 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, telecommunications, monitors, electronic test equipment etc.

• No resonance with power factor correction capacitors

Flexible battery management (FBM)

Premature battery deterioration is avoided by the advanced management of battery charging and preventive failure
diagnostics. The major benefits are:

• AC-ripple-free battery charging due to a dedicated dc-dc charger independent from the rectifier and inverter

• Wide range of number of battery blocks (30-50 x 12V blocks, depending autonomy times)

• 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 the Advanced Battery Diagnosis (ABD) algorithm

• User-selectable battery tests to ascertain the battery state

• Optional temperature compensated charging regime to enhance battery life

Decentralised Parallel Architecture (DPA)

In a ‘redundant’ parallel UPS system the power modules’ outputs are connected in parallel so that if one module fails the
remaining modules can sustain the load supply. Such operation requires a certain amount of inter-module communication

to control frequency synchronisation, load sharing, load transfer etc. This is achieved by having a master-slav e
relationship among the power modules whereby the master logic gives out individual commands to all the slave units to

keep them in step.

In some designs this can unfortunately lead to a single-point-of-failure for the entire system if the master logic or

communication with the slaves fails; however, the PowerWave 9000 technology uses multi-master logic with separated
independent regulation and control logic busses which enables any of the connected power modules to adopt the master

role if called upon. This control philosophy maintains the high

est possible system availability.

This unique decentralized design:

• Enables a parallel redundant system providing 100% conditioned power at all time

• Eliminates the system-level single point of failure inherent in traditional parallel UPS systems

• Exponentially increases the reliability of the overall system

2.3 Functional description of operation

This section describes:

• The internal operation of an individual UPS power module at block-diagram level (see paragraph 2.3.1)

• The various operational modes of an individual UPS power module (see paragraph 2.3.2)

• UPS system operational modes – ‘On-line’ versus ‘Off-line’ system operation (see paragraph 2.3.3)

• Multi-module system operation and paralleling considerations (see paragraph 2.3.4)

2.3.1 PowerWave 9000 Module block diagram

Figure 2.3 shows a functional block diagram of a PowerWave 9000 cabinet containing two power modules.

UPS Input supplies

The mains supply (1) is a standard 3ph+N supply which is connected to the rectifier section of each power module. During
normal operation this supply is rectified to provide a DC input to the inverter and also powers the battery charger.

A 3ph+N bypass supply (2) is shown connected via a fused isolator (F2) to the static switch within each power module. It
is also to the cabinet’s maintenance bypass switch (IA1). In a standard installation the bypass supply terminals (2) are
usually linked to the mains supply terminals (1) within the cabinet so only one mains supply feed is required. (See
paragraph 3.6.3 for details concerning ‘Single Feed’ & ‘Dual Feed’ input supply configurations.)

Figure 2.3 PowerWave 9000 UPS block diagram (2 modules fitted)

Each power module is wired to individual battery connections on the cabinet’s main terminal block (3). This terminal block
is then connected to internal batteries in the case of the DPA 50 and DPA 150 cabinets, or to an external battery cabinet in
the case of the DPA 250.

If required, two or more power modules can be connected to a common battery by linking together the modules’ battery
terminal block connections (3), as described in paragraph 3.8. However, by employing a separate battery bank for each
module it again avoids a potential single point of failure and effectively extends the system redundancy to include the
batteries – which is highly recommended.

UPS Output (load) supply

Figure 2.3 shows that the UPS output (Load Supply) can be provided through one of three power paths depending on the
UPS operating mode:

• From the inverter (4), via the static switch and isolator IA2

• From the static bypass line (5) via the static switch and isolator IA2

• From the maintenance bypass line (6) via the maintenance bypass isolator IA1

The criteria for operating under each of these UPS modes is described below.

2.3.2 UPS Module operating modes

The diagrams in this section illustrate cabinet fitted with a single power module. Where two or more power modules are
fitted they will always adopt the same operating mode due to the parallel control logic signals.

Load on Inverter

Figure 2.4 Load on inverter

This is the normal operating mode and the only one that provides the load with continuously processed and backed-up
power. In this mode, the mains supply is converted to DC by the rectifier which then charges the battery and provides
operating power for the inverter; which converts the rectifier output back to AC suitable for powering the load.

The inverter output frequency is synchronised to the bypass supply provided it remains within preset limits. If these limits
are exceeded, or if the bypass supply fails altogether, the inverter frequency control reverts to a free-running oscillator that
will produce a constant 50/60Hz UPS output.

2: General Description

If the mains supply fails, the LINE 1 led will extinguish and the rectifier will shut down. The battery now provides an
alternative DC power source for the inverter via the charger/booster and the BATTERY led will flash green to indicate that
it is on load.

Larger installations often include a standby generator which is designed to start-up and connect to the UPS automatically
within a short period of time following a mains failure. Once the UPS input power is restored from the standby source the
rectifier and charger will resume normal operation, which results in very short battery discharge periods.

In the case of a dual feed input – if the bypass supply remains live, the LINE 2 led will stay illuminated and the inverter

frequency will remain synchronised to the bypass provided it stays within its preset limits.

In the case of a single feed input – the bypass supply will fail at the same time as the mains supply and the LINE 2 led will

extinguish along with the LINE 1 led. Under these circumstances inverter frequency will revert to a free-running oscillator
that will produce a constant 50/60Hz UPS output.

Battery discharge operation

Various alarms are generated at preset levels as the battery discharges. This allows the operator observe the remaining
autonomy and, if required, shut-down the load in an orderly manner (e.g. to save data) before the battery reaches its final
end-of-discharge voltage. Various options are available to automate the load shut-down process, as described in Chapter
8 of this manual (Options).

When the battery is initially put on load the BATTERY led will flash green, as shown in Figure 2.5. This will continue until
the remaining autonomy time falls to 3 minutes whereupon the led will begin flashing red and if a data protection
application, such as WAVEMON, is installed it will begin its automatic PC shutdown routine at this point.

When the battery reaches its fully discharged voltage the BATTERY led will change to solid red and the UPS will attempt to
transfer the load to the bypass supply if it is present.

Load on Bypass

Figure 2.6 Load on bypass

In the ‘load on bypass’ mode the load supply is connected to the unprocessed static bypass line via the static switch.

Depending on the reason for switching to bypass operation (i.e. manually transferred or transferred due to a fault), when
operating in this mode the rectifier/charger section can be turned off entirely or remain running, and continue to provide
battery charging (as shown above). Similarly, the inverter may have been manually turned OFF or shutdown due to a fault,
and the INVERTER led may be OFF or solid RED.

Static switch operation

The static switch is a solid state switch contained in each power module and operated by the module’s microprocessor
control logic which ensures that the static switch of all the power modules connected to the load (through IA2) are always
in the same operational state. It is not permissible for one module to be operating with ‘load on inverter’ while the
remaining modules are in the ‘load on bypass’ mode as such a situation would cause damage to the modules.

During normal operation the load is transferred from the inverter to the static bypass line in the event of an overload or loss
of system redundancy due to a failed power module. Load transfer can also be initiated manually via the UPS operator

control panel located on the front cabinet door (see paragraph 2.3.3).

Load on Maintenance Bypass

Figure 2.7 Load on maintenance bypass

In this mode of operation the manually closed maintenance bypass switch (IA1) connects the load supply directly to the
unprocessed bypass supply. This is used to keep the load supplied (albeit without any power protection) whilst allowing
the remainder of the UPS system to be shut down for service repair.

To prevent possible inverter damage, it is important that the inverter output and maintenance bypass lines are never
connected in parallel. Therefore when transferring from the ‘load on inverter’ mode to the ‘load on maintenance bypass’
mode it is important that the load is first transferred to the static bypass (‘load on bypass’ mode) before the maintenance
bypass switch is closed.

2.3.3 UPS System operating modes

The previous section described the operating modes of the UPS power module: but UPS systems are also categorised
according to the way in which they are used at a ‘system’ level; and are typically described as being an ‘on-line’, ‘off-line’
or ‘line interactive’ UPS system. The PowerWave 9000 can be operated in all three of the above categories.

On-line operation

When used as an ‘on-line’ UPS system, the PowerWave 9000 UPS modules normally operate in their ‘load on inverter’
mode and will switch over to ‘load on bypass’ in the event of an inverter fault or overload which exceeds the system
redundancy. This will transfer the load to the static bypass without interruption (transfer time = 0).

If the transfer is due to an overload the UPS modules will switch back to the ‘load on inverter’ mode if the overload clears
and the inverter returns to normal operation. An ‘on-line’ system therefore provides the highest degree of load protection
and is always recommended if the critical load will not tolerate even a very brief supply interruption.

Off-line / line interactive operation

When the PowerWave 9000 is used as an ‘off-line’ or ‘line-interactive’ UPS system it normally operates in its ‘load on
bypass’ mode with the load being supplied through the static bypass supply; however the rectifier and battery charger are
still powered up to maintain battery charging, and the inverter section is enabled and operating on standby.

In the bypass supply fails the static switch will automatically transfer the load to the inverter within 3-5ms, and if the
rectifier input mains supply is missing when the transfer takes place the inverter will operate from battery power.

If the bypass supply returns to normal when operating with the ‘load on inverter’, the load automatically transfers back to
the static bypass (‘load on bypass’ mode) and the inverter returns to its standby function.

An ‘off-line/line interactive’ system is a slightly more efficient than an ‘on-line’ system due to the reduced rectifier/inverter
losses during normal operation and it is sometimes referred to as the “ECO” mode. However this mode is recommended
only if the connected load equipment can tolerate power interruptions of up to 3 to 5 ms during the transfer period.

WARNING: always follow the operating instructions in this manual when starting or shutting down the UPS.

2: General Description

2.3.4 Multi-module parallel system operation

As described above, the PowerWave 9000 cabinets are designed to
accommodate between one and five UPS power modules. Each module
has an individual output power isolator (IA2) which connects the module's
output to the cabinet’s output power terminals. This enables an individual
module to be disconnected from the load supply for maintenance or
repair purposes.

Under normal conditions all the modules within the cabinet are turned on
and operating in parallel to provide the cabinet’s rated output.

‘Capacity’ versus ‘redundant module’ system

The paralleled UPS modules can be operated as either a capacity or
redundant module system.

The difference between the two is that a ‘capacity’ system is rated such
that ALL the power modules are required to furnish the specified full load
power, whereas a ‘redundant-module’ system is designed with one (or
more) modules over and above that required to supply the full load.

In a redundant-module system it is therefore possible to lose one (or
more) power module without disrupting the load, whereas this is not the
case in a capacity system where the loss of one power module would
automatically transfer the load to the bypass supply.

Parallel control bus

All the UPS power modules within a cabinet are connected to a parallel control bus which carries various inter-module
control signals used for frequency synchronisation, load sharing etc. By using sensing signals passed over the parallel
control bus, each power module can electronically compare its own frequency and output current with that of its
neighbouring module and carry out fine adjustments to achieve balanced conditions.

The module control logic always observes one of the power modules as being the ‘master’ and the others as ‘slaves’.
However if the ‘master’ module goes faulty at any time the next module in the chain (a former ‘slave’) will immediately take
over the role of master and the former master module will turn off.

Multi-cabinet parallel system

To further expand the overall UPS system capacity, several (up to ten) PowerWave 9000 cabinets can be connected
together to operate as a ‘multi-cabinet’ parallel system. This is achieved by connecting each cabinet’s output power
terminals in parallel at an external load distribution panel and linking together the parallel control bus in each cabinet to
effectively provide a single parallel control bus that is connected to every power module in the system – see Figure 2.9.

Taken to its limit, a system comprising ten fully populated DPA-250 cabinets would result in a UPS system rating of
2500kW; however, such large systems are rare and a typical multi-cabinet installation will contain far fewer than the
maximum ten cabinets.

It is essential that any installed UPS power protection system can be expanded to meet a growing load demand without
compromising the existing load supply.

This condition is easily managed by a PowerWave 9000 system which, due to its ‘hot-swappable’ design, makes it
possible to fit an additional power module to a DPA-150 or DPA-250 cabinet if it is not already fully populated, or add a
further cabinet to an existing UPS system without disrupting the load supply.

Note: Every standard PowerWave 9000 cabinet is supplied with all the features required for parallel operation to eliminate

any need for time-consuming or expensive upgrading on site.

WARNING: The on-line mode must always be used for critical load protection.

2.5.1 UPS Module control panel keys

The keys on the operator control panel allow the user to:

• Make settings and adjustments via a menu driven LCD display

• Start-up and shut-down the UPS and transfer the load between inverter and bypass

• Monitor and display the UPS operating voltages, currents, frequencies and other values on the LCD display

• Reset/cancel an alarm

Key function summary

ON/OFF Keys

The UPS can be switched ON or OFF by simultaneously pressing both ON/OFF keys on the control panel. The
requirement to press both buttons is to help avoid accidental UPS start-up or shutdown operation.

During normal operation, pressing the two ON/OFF buttons simultaneously will immediately shutdown the UPS module.

• In a single module system (e.g. DPA-50) this will disconnect the UPS from the load unless the load is first
transferred to the maintenance bypass.

• In a parallel module system the power module will shutdown and be disconnected from the load bus. However, the
load may or may-not transfer to the static bypass depending on whether or not the number of remaining live
modules satisfies the system’s redundancy – i.e. if there are a sufficient number of modules remaining to support
the system’s load then the load will not be transferred.

Note: To shut down all the modules in a parallel system you must press both

ON/OFF

buttons on every module.

3.1 Introduction

This chapter contains essential information concerning the unpacking, positioning, installing and cabling of the
PowerWave 9000 UPS.

3.2 Taking receipt of the UPS

The UPS cabinet and accessories are delivered on purpose designed pallets that are easy to off load and move using a
forklift or suitable pallet jack.

The packing container protects the UPS from mechanical and environmental damage during transit. This protection is
further increased by wrapping the PowerWave 9000 UPS with a plastic sheet.

Upon receiving the UPS you should carefully examine the packing container for any sign of physical damage. The external
'Tip&Tel' (“FRAGILE” and “ARROW”) indicator should be intact if the equipment has been correctly transported in an
upright position. If the packaging has been ruptured in transit, or if the 'Tip&Tel' indicator is suspect, inform both the carrier
and Uninterruptible Power Supplies Ltd immediately.

Ensure that the received UPS equipment corresponds to the description indicated in the delivery note.

3.2.1 Site transportation

Please observe the following precautions when you transport the UPS equipment from the off loading site and its intended
installation (or storage) location.

3

Installation

WARNING: All cabling operations must be supervised by an authorised electrician or other suitably

qualified person. All installation and operating procedures must be carried out in strict accordance with the
instructions contained in this manual. Uninterruptible Power Supplies Ltd will take no responsibility for any
personal injury or material damage caused by the incorrect installation, cabling or operation of this product.

WARNING: Once the UPS equipment is installed it must be commissioned by an engineer approved by
Uninterruptible Power Supplies Ltd 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.

• Due to the high-energy batteries involved and heavy weight, do not sta ck the pallets.

CAUTION: Claims for visible shipping damage must b e notified to the carrier imme diately on recei pt. Other
shipping damage claims must be filed immediately when found and the carrier must be informed within a
maximum of 7 days following receipt of the equipmen t.
If shipping damage is discovered, store all packing materials for further investigation.

CAUTION: Transportation:

• When transporting the equipment, use the fron t an d rear shippi ng b rackets to secu re the cab inet to
help prevent the UPS from toppling over.

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

UPS471-02-00 PW9000DPA User Manual UK Dated 06/08/14 23

3: Installation

3.3 Unpacking

If the packages are received in good order (i.e. the ‘tip & tell’ “FRAGILE” and “ARROW” indications on the packing
container are intact) then unpack the UPS and any accessory equipment 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 equipment.

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

3. Remove the plastic sheeting covering the UPS.

4. Remove any anchor bolts securing the cabinet to the pallet then 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 found.

7. Check that the details on the UPS nameplate corresponds to the purchased material mentioned in the delivery note.
The rating specifications can be found on a nameplate located inside the UPS door.

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

3.4 Storage

UPS Cabinet

If you plan to store the UPS cabinet prior to use it should be held it in a clean, dry environment with a temperature between

-5°C to +40°C and RH <90%. The UPS should preferably be stored in the original packing and shipping carton, but if the

packing container is removed you must take measures to protect the UPS from dust.

Battery

The UPS uses sealed, maintenance-free batteries whose storage capacity depends on the ambient temperature. It is
important not to store the batteries for longer than 6 months at 20°C, 3 months at 30°C, or 2 months at 35°C storage
temperature without recharging them.

For longer term storage the batteries should be fully recharged every 6 months @20°C.

CAUTION: Potential dangers:

• If the UPS/battery cabinet is tilted by more than 10° it could ca use internal da mage. If tilting occurs
do not connect the UPS to the mains electrical supply.

• The weight of the UPS/battery equipment can cause serious personal injury and/or structural
damage to the surrounding area if dropped in tran sit. Always take extreme care when moving the
equipment.

CAUTION: Storage:

• The UPS should be stored in the original packing and shipping carton.

• The recommended storing temperature fo r the UPS system and batteries is between +5°C and
+40°C.

• The UPS system and the battery sets must be protected from high humidity which should not
exceed 90% RH (non-condensing).

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

CAUTION: Sealed batteries must never be stored in a fully or partially discharged state. Extreme
temperature, under-charge, overcharge or over-discharge will destroy batteries!

• Charge the battery both before and after storing.

• Always store the batteries in a dry, clean, co ol environment in their original packaging.

• If the packaging is removed protect the batteries from dust and humidity.

3.5 Planning the installation (site considerations)

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

1. The route to the installation location must allow the equipment to be transported in an upright position.

2. The floor at the proposed installation site 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. Locations with high ambient temperature, moisture or humidity must be avoided.

a) The installation site humidity should be <90% non-condensing.
b) The prescribed ambient temperature is +15°C to +25°C. An ambient temperature of 20°C is recommended to

achieve a long battery life.
c) Any requested cooling air flow must be available. The air entering the UPS must not exceed +40°C.
d) The air conditioning system must be able to provide a sufficient amount of cooling air to keep the room within the

prescribed temperature range.

4. The following environmental conditions should also be considered:

a) Fire protection standards must be respected. The floor material should be non-flammable.
b) The location must be free of dust and corrosive/explosive gases.
c) The location must be vibration free.
d) If the UPS is located in bayed enclosures, partition walls must be installed.
e) The available space must permit the minimum cabinet clearances shown below.

3.5.1 Clearances

Figure 3.1 UPS & Battery cabinet clearance requirements

The UPS cabinet requires space to bottom/front and back to enable cooling airflow. Suitable ventilation airflow must be

provided (See Figure 3.1).

All parts of the UPS required for maintenance, servicing and user operation are can be accessed from the front of the
cabinet; a clearance of 1000mm space should be provided at the front of the UPS cabinet to enable component removal.
Cabling is also carried out from the front of the cabinet.

3.6 Planning the installation (cabling considerations)

3.6.1 General requirements

The information in this section should help with the preparation and planning of the UPS power cabling.

It is the customer’s responsibility to provide all external fuses, isolators and cables that are used to connect the UPS input
and output power supplies. The UPS input and bypass terminals should be connected to the utility mains supply through a
suitable LV-Distribution board containing a circuit breaker or fused isolator to provide both overload protection and a
means of isolating the UPS from the mains supply when required. Similarly, the UPS output supply terminals should be
connected to the load equipment via a suitably fused load distribution board.

Input neutral grounding

A permanently connected input neutral is
required to enable the rectifier to operate
correctly and allow the UPS to function
properly when operating on battery. The input
neutral must also be grounded to permit
correct operation when the UPS is running on
battery.

3.6.2 UPS Cable and fuse sizing

Single feed / dual feed inputs

The UPS can be wired for a ‘single feed’ input (standard), whereby the UPS input supply terminals and bypass supply
terminals are internally linked; or it can be wired for a ‘dual feed’ input, where the bypass links are removed and the UPS
bypass terminals are connected to a dedicated ‘bypass’ supply.

Both configurations are shown in Figure 3.3 (single feed) and Figure 3.4 (dual feed) together with details of the
recommended fuse and cable ratings

Note: All cabinets must be cabled according to their full rated output even if the cabinet is not fully populated with power

modules at the time of installation. This allows for future expansion to be carries out safely.

Key Point: As the input neutral must
be unswitched and connected to the
UPS at all times. DO NOT use, a 4­pole input switch or isolator at the LV
Distribution board on a TN-S system.

Key Point: The information in figures 3.3 and 3.4 is given for guidance only:

• Fuse and Cable recommendations are to IEC 60950-1:2001.

• All external fuses, isolators and power cables must be rated and installed in accordance with the
prescribed IEC standards or local regulation – e.g. BS7671:2008.

• External DC Cables and battery fuses are bespoke to the installation.

3.6.3 UPS Power cable termination sizes

The table below gives details of the cable termination sizes applicable to the various models across the PowerWave 9000
range.

3.6.4 UPS Power connection details

Figures 3.5 to 3.7 illustrate the power terminal connections for the DPA-50, DPA-150 and DPA-250 UPS cabinets
respectively. In each case the diagrams depict a single feed input supply with links fitted between the Mains and Bypass
input supply terminals. This is the standard configuration and the identified links must be removed for dual feed operation
is required.

The diagrams for the DPA-150 and DPA-250 models also show optional links adjacent to the external battery terminal
connections. If a common battery is used, these links must be fitted to the terminals shown so that the external battery is
connected to all the fitted power modules.

Note: Best UPS system reliability is achieved when using an independent battery bank for each power module as this

extends the module redundancy to include the battery – i.e. when using an independent battery configuration only one
power module will be affected in the event of a battery failure.

3.6.6 Battery cabling considerations

The PowerWave 9000 UPS battery comprises a number of (30-50) sealed, maintenance-free batteries that are mounted
either within the UPS cabinet (DPA-50 & DPA-150) or in an external battery cabinet(s) (DPA-250). An external battery
cabinet can also be used in conjunction with the DPA-50 or DPA-150 to increase the available battery autonomy time if
required.

A number of battery blocks are connected in series to form a battery string of the required voltage and capacity, and
connected to three power terminals annotated ‘+’ ‘–’ and ‘N’. The plus and minus connections are taken from the battery
string positive and negative extremities, and the ‘N’ terminal is connected to a point exactly mid-way in the battery string.
For this reason the string must comprise an even number of battery blocks.

Battery configuration

Two battery configurations are possible:

• Common battery – where all the power modules are connected to the same battery source (although that source
may itself comprise several battery strings connected in parallel). This requires ‘common battery’ links to be fitted
to the UPS battery power terminals, as shown below.

• Individual battery – where each module is connected to an individual battery string.

These configurations are illustrated in Figure 3.9, which shows the alternative connections for internal batteries in a DPA­150 cabinet fitted with three power modules. Figure 3.10 shows an example of the alternative connections when using an
external battery cabinet shown connected to a DPA-250 (5 module) cabinet.

3.9 Multi-cabinet configuration and paralleling cables

In a multi-cabinet system a series of communication bus cables must be connected between each cabinet to enable
various parallel control functions to operate. Each module must also be configured to identify its position within the parallel
system – e.g ‘first’, ‘middle’ or ‘last’ module. The module set up to be the ‘first’ module in the chain acts as the ‘master’
module in relation to the inter-module parallel control logic.

Figure 3.17 Cabinet interface board

Setting the configuration DIP Switch SW1-9

DIP Switch SW1-9, located on the UPS interface board (see Figure 3.17), is used to configure the position of the cabinet
in the parallel UPS chain. Using this switch you can define the cabinet’s position as:

• the first (‘master’) cabinet in the chain (e.g. cabinet 1 in Figure 3.18).

• the middle cabinet in the chain (there may be more than one middle cabinet).

• the last cabinet in the chain (e.g. cabinet n in Figure 3.18).

1. Set DIP Switch SW1-9 of each cabinet according to the table below:

Key Point: This section is required only if two (or more) cabinets are to be connected in a multi-cabinet parallel
configuration, as described paragraph 2.3.3.

WARNING: Before making the following connections ensure that all the UPS cabinets are powered down
and all parallel isolators (IA2) are open.

4: Operation

4.1 Introduction

The PowerWave 9000 UPS system must be commissioned by a fully trained field service engineer authorised by
Uninterruptible Power Supplies Ltd before it is put into use.

The commissioning engineer will:

• Connect the UPS batteries.

• Check the UPS electrical installation and operating environment.

• Check the UPS cabinet paralleling configuration settings.

• Check the installation of any optional equipment.

• Perform a controlled UPS start-up and functionally test the system for correct operation and configuration.

• Carry out customer operator training and equipment handover.

4.1.1 Operating procedure summary

Under normal circumstances all the UPS modules in a multi-module system are running and operating in their ‘on-line’ (on
inverter) mode. If a module fails, in a redundant module system the faulty module will shut down but will not affect the
remaining on-line modules, which will continue to supply the load with processed power. The failed module can then be
replaced or tested off-line without affecting the remaining working modules.

If a UPS module fails in a capacity (or single module) system, the faulty module is shut-down and the load is immediately
transferred to the static bypass supply (in all modules) from where it is supplied with unprotected mains power.

The UPS cabinet contains a maintenance bypass switch which, when closed, completely bypasses the UPS modules and
connects the cabinet output terminals directly to its bypass mains input. When operating via the maintenance bypass
switch, the UPS modules can be replaced or tested off-line as required. In the case of a single module installation the load
must be transferred to the maintenance bypass to maintain the load power while the UPS module is replaced.

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

4.2 Operating Instructions

The following procedures are provided in this section:

• Starting the UPS system from the maintenance bypass (see paragraph 4.2.1).

• Individual module start/stop procedure in a parallel system (see paragraph 4.2.2).

• Transfer the load from UPS to maintenance bypass mode (see paragraph 4.2.3).

• Complete system shutdown (see paragraph 4.2.4).

5: Maintenance

5.1 Introduction

5.2 System calibration

To ensure optimum UPS operation and continuous, efficient protection of the connected load, it is recommended that the
system’s operating parameters are checked every six months and recalibrated where necessary. The batteries should
also be checked every six months, depending on the ambient temperature.

5.3 User responsibilities

There are no user-serviceable parts contained within the UPS so the maintenance requirements of the user are minimal.
To maximise the useful working life and reliability of the UPS and its batteries, the environment in which the UPS operates
should be kept cool and dust free.

5.4 Routine maintenance

It is essential that the UPS system and batteries receive regular preventative maintenance inspection to maximise both
the useful working life and the reliability of the UPS system. When the UPS is commissioned, the commissioning field
service 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.

Preventative maintenance inspections involve working inside the UPS which contains hazardous AC and DC voltages.

During a preventative maintenance inspection the field service engineer will check:

• Site/environment conditions

• Integrity of electrical installation

• Cooling airflow

• Rectifier operation and calibration

• Inverter operation and calibration

• Static switch operation

• Battery status

• Load characteristics

• Integrity of alarm and monitoring systems

• Operation of all installed options

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

For further details on Extended Warranty Agreements see paragraph 2.7.

7.5 SNMP/ Modem slots for remote monitoring/control

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 PowerWave 9000 contains two SNMP slots; one is designed to house a Modem/Ethernet SNMP adapter card and the
other a Modem/GSM adapter (see Figure 7.1). Alternatively, SNMP connectivity can also be implemented using an
external SNMP adapter connected to the UPS RS232 output (JD11).

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.

Figure 7.7 SNMP Internal and external SNMP adapters

7.6 UPS Monitoring and automated control software

7.6.1 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 PowerWave 9000 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 PowerWave 9000 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. The system comprises a bespoke
software package which is installed on a local PC and communicates with the UPS over a standard RS232 cable of up to
15m in length.

7.6.2 WAVEMON Shutdown and Management Software

Figure 7.8 Monitoring screen image.

WAVEMON is a software application designed to operate with many of the systems supplied by Uninterruptible Power
Supplies Ltd and features both UPS monitoring and automatic UPS/server shutdown facilities. It 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.

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.

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.

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 is sent to the connected users. These ‘system event’ routines
are a part of the management software and can be configured in accordance with local application requirements.

The software of your PowerWave 9000 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.

2. 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.

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.

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.

Note: Virtual servers may not need a licen se per virtual server client. Ple ase contact Technical Suppo rt to discuss you

requirements.
