2.2 PowerWave PW3000/TP Model range

The PowerWave PW3000/TP range comprises 10kVA and 20kVA UPS models, contained in identically sized cabinets. Depending on the required autonomy time, the UPS batteries can be housed within the UPS cabinet (with various battery arrangements) or housed in a purpose designed and matching battery cabinet which can be installed adjacent to the UPS cabinet to form an aesthetically pleasing suit. Although the UPS produces a single-phase a.c. output, it can be connected to either a single or three phase input supply. It can also be used in a frequency changer role with 50Hz/60Hz input/output or vice versa.

Up to four UPS cabinets can be connected in parallel to increase the overall system output capability or introduce a level of module redundancy to further enhance the system availability

UPS Mains input supply

The UPS mains input can be connected to a 3ph+N or 1ph+N supply. It is connected to the Rectifier/DC Converter via the ‘Mains 1’ (M1) input breaker and a fuse on the Input RFI Filter. If a single phase input supply is used, the three input line terminals are linked together and the contacts of the input breaker (M1) are effectively paralleled.

Key Point: In a parallel system ALL the connected modules must be of the same output rating – i.e. it is not permissible to combine 10kVA and 20kVA cabinets in a parallel system.

2: General Description

UPS Bypass input supply

A single phase bypass supply is connected directly to the Maintenance Bypass Switch and also to the bypass side of the static switch, via the ‘Mains 2’ (M2) breaker and a fuse on the Input EMI Filter. In a standard installation the bypass input terminals are usually linked to the mains input supply L1 terminal, so only one mains supply feed is required. This is often referred to as a ‘Single Feed’ input configuration, as opposed to a ‘Dual Feed’ input where a separate bypass supply is used. (See paragraph 3.7 for details concerning ‘Single Feed’ & ‘Dual Feed’ supply configurations.)

Battery charger

The battery charger can be powered from either the Mains Input or Bypass Input supply, and charges the internal (or optional external) batteries when either of these supplies is present. It’s power source is selected by a relay which automatically switches over to the Bypass Input supply when the Mains Input is not available. The charger is rated at 2A but can be increased to 4A if required, depending on battery topology.

Rectifier / DC Converter

The Rectifier / DC Converter produces a controlled DC voltage for the Inverter input. This can be sourced either from the UPS Mains input supply (AC) of from the battery (DC). An automatic changeover switch ensures that the two sources are never connected to the Rectifier /DC Converter simultaneously, with the UPS Mains input always being accepted as the preferred source provided it remains within specified limits.

Power Inverter

A single phase Inverter converts its DC input from the Rectifier / DC Converter into the required UPS output AC supply. The output voltage is tightly regulated using advanced PWM techniques and the output frequency is similarly controlled. Usually, the inverter operates at the same frequency as the UPS input/bypass supply; however, the UPS can be operated in a frequency-changing mode whereby the input and output frequencies are different – e.g. 50Hz/60Hz input/output. Note that when used as a frequency-changer, the UPS bypass circuit is automatically inhibited.

Static switch

The static switch block contains two static switches connected across a load transfer relay, one is connected to the bypass supply and the other to the inverter output. When the load is transferred between the bypass and inverter the appropriate static switch turns on for a brief period to maintain the load supply while the load transfer relay operates. The microprocessor system automatically controls the load transfer between inverter/bypass sources as dictated by local conditions (e.g. overload) and provides a means of performing a manual load transfer.

Output relay

The output relay is used to connect/disconnect the UPS output in a parallel module system, and enables the UPS to be quickly isolated from the system in the event of a UPS fault.

Maintenance bypass switch

The Maintenance Bypass Switch connects the UPS AC Output terminals directly to the Bypass Input and provides a means of temporarily supplying the load from the raw mains while the UPS is otherwise shut-down for maintenance repair. It operates in a make-before-break fashion to ensure the load is supported during the transfer.

In order to protect the UPS inverter, the load must be transferred to the static bypass supply before the Maintenance Bypass Switch is closed – this is performed automatically when the Maintenance Bypass Switch access cover is removed.

When the load is connected via the maintenance bypass the UPS can be shut down safely for repair, with the only remaining live areas within the UPS being the input/output power connections and isolators.

UPS AC Output (load) supply

Figure 2.1 shows that the UPS output (Load Supply) can be provi

ded through one of three power paths depending on the

UPS operating mode – the criteria for operating under each of these UPS modes is described in 2.3.2:

• From the inverter, via the inverter-side static switch and output relay

• From the static bypass line via the bypass-side static switch and output relay

• From the maintenance bypass line via the maintenance bypass switch

2.3.2 UPS Module operating modes

All the diagrams in this section depict a single UPS cabinet. Where two or more cabinets are operating as a parallel system they will always adopt the same operating mode due to their parallel control logic signals.

Load on Inverter

Figure 2.2 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 controlled DC by the Rectifier/DC Converter then converted back to the rated AC output voltage by the Inverter and connected to the load via the inverter side of the static switch.

The inverter output frequency is synchronised to the bypass supply provided it remains within preset limits; and 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 50Hz (or 60Hz) UPS output.

Load on Battery

Figure 2.3 Load on battery

If the mains supply fails, the rectifier will shut down and the battery will provide an alternative DC power source for the inverter via the DC converter. The yellow ‘Battery’ led will illuminate on the control panel to indicate that it is on load and a ‘ON BATTERY’ status indication will be displayed on the LCD, accompanied by an audible alarm.

In the case of a dual feed input – if the bypass supply remains live 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 under these

circumstances the inverter frequency will revert to a free-running oscillator that will produce a constant 50/60Hz output.

2: General Description

Some installations include a standby generator which is designed to start-up automatically and provide an alternative UPS power input within a short period following a mains failure. Once the UPS input power is restored from the standby generator, the rectifier and charger will resume normal operation.

Battery discharge operation

As the battery discharges, various options are available to automate the load shut-down process, as described in Chapter 8 of this manual.

A SHUTDOWN IMMINENT alarm indicates when the battery is almost exhausted, with approximately 3 minutes autonomy time remaining, and if a data protection application is installed it will begin its automatic PC shut down routine at this point. When the battery reaches its fully discharged voltage the UPS will attempt to transfer the load to the bypass supply but if the bypass supply is unavailable then the UPS will totally shut down.

Load on Bypass

Figure 2.4 Load on bypass

In the ‘load on bypass’ mode the UPS AC Output is connected to the unprocessed static bypass line via the bypass side of the static switch.

During normal operation the load will be transferred from the inverter to the static bypass line in the event of an inverter fault, output overload, or loss of system redundancy due to a failed module in a parallel module system. Load transfer can also be initiated manually via the UPS control panel.

Depending on the reason for the load being transferred to bypass (i.e. manually transferred or transferred due to a fault), The Rectifier/DC Converter and Inverter power blocks might turn off or remain running.

8 TS_604_01 PowerWave PW3000/TP User Manual UK 5/1/18

In this mode of operation the manually closed maintenance bypass switch connects the UPS AC Output 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 internal operating modes of an individual UPS 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 ‘online’, ‘off-line’ or ‘line interactive’ UPS system. The PowerWave PW3000/TP can be operated in all three categories.

On-line operation

When used as an ‘on-line’ UPS system, the PowerWave PW3000/TP UPS normally operate in its ‘load on inverter’ mode and will automatically change over to ‘load on bypass’ in the event of an inverter fault or overload. The bypass-side static switch will transfer the load to the bypass supply without interruption (transfer time = 0).

If the transfer is due to an overload the UPS will attempt to switch back to the ‘load on inverter’ mode if the overload clears while on bypass, 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.

If the load fails to successfully re-transfer to inverter three times within ten minutes, further transfer attempts will be locked out – the load will remain on bypass and a warning message will appear on the LCD screen.

Off-line and line interactive operation (HE / ECO mode)

When the PowerWave PW3000/TP is used as an ‘off-line’ or ‘line-interactive’ UPS system it normally operates in the ‘load on bypass’ mode with the load being supplied through the static bypass supply; however the rectifier/DC Converter and battery charger are still powered up to maintain battery charging, and the inverter section is enabled and on standby.

Figure 2.6 ECO (Off-line) mode of operation

If the bypass input supply fails, the static switch will automatically transfer the load to the inverter within 3-5ms; and if the rectifier’s mains input supply is missing when the transfer takes place the inverter will operate immediately from battery power (‘load on battery’ mode). When the bypass supply returns to normal, the load automatically transfers back to the static bypass line (‘load on bypass’ mode) and the inverter returns to its standby operation.

An ‘off line’ system is a slightly more efficient than an ‘on-line’ system due to the reduced rectifier/inverter losses during normal operation, and for this reason it is sometimes referred to as the ‘High Efficiency (HE)’ or ‘Economy ECO’ mode.

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

2: General Description

2.3.4 Optional operating mode settings

The above descriptions refer to the UPS operation in what can be considered to be a ‘standard’ installation. However, the operation can be modified to suit local conditions, or particular load supply requirements, by adjusting the selected values in the LCD SETTINGS sub-menu, as shown in Figure 2.17.

Note: These settings are password-protected and can only be changed by authorised service personnel.

Auto Restart

If the input mains supply fails, and no bypass mains supply is available, the UPS will operate on-battery and shut down when the battery reaches its end of discharge voltage, or immediately if the battery is disconnected. The Auto restart setting determines whether or not the UPS restarts automatically following the return of the input mains.

The default value for Auto restart is [Enabled]. This means that if the UPS shuts down following a mains failure it will restart automatically and return the load to the inverter when the mains supply returns. If Auto restart is [Disabled] the UPS will have to be restarted manually.

Note: If the UPS shuts down due to an overload, an automatic restart can be [

Enabled

] or [

Disabled

] by setting the

separate

Automatic overload restart

parameter.

Auto Bypass

In a ‘standard’ installation the load will be transferred to the bypass supply (if available) if the inverter shuts down due to an overload, inverter fault or a fully discharged battery when operating on battery power. However, in areas where the mains supply is unstable the automatic transfer to bypass function can be inhibited by setting the Auto bypass to [Disabled].

Note: If

Auto bypass

is [

Disabled

] the UPS will shut down (and drop the load) when it is operating on battery power

and the battery reaches its end of discharge voltage.

Short Circuit Clearance

This parameter determines how the UPS reacts to a short circuit on its output.

If a short circuit is detected the inverter will limit its output current to 100% by reducing its output voltage – once the short circuit is cleared the output current will fall below 100% and the output voltage will return to normal.

By default the Short circuit clearance is set to [Disabled], and in this case the inverter will continue to supply 100% load for 100 ms. After this time the UPS is shut down if its output voltage is still <50%

If Short circuit clearance is [Enabled], the inverter short circuit clearance time is extended to 4 seconds.

2.3.5 Multi-module parallel system operation

To expand the overall UPS system rating, up to four PowerWave PW3000/TP UPS cabinets can be connected together to operate as a parallel UPS 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 common parallel control bus. The parallel control bus cable is connected to a socket located near the top rear of the cabinet which is covered by a blanking plate when not used (item 12 in Figure 2.7).

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 situation is easily managed by a PowerWave PW3000/TP system which makes it possible to add a further cabinet to an existing UPS system without disrupting the load supply.

Note: Every PowerWave PW3000/TP cabinet is supplied with all the features required for parallel operation to eliminate

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

WARNING: This mode is recommended only if the connected load equipment can tolerate a power interruption of up to 3 to 5 ms during the transfer period. The ‘on-line’ mode must always be used for critical load protection.

2: General Description

10 TS_604_01 PowerWave PW3000/TP User Manual UK 5/1/18

‘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 UPS modules are required to furnish the specified full load power, whereas a ‘redundant-module’ system is designed with one (or more) UPS module over and above that required to supply the full load.

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

Parallel control bus

All the UPS modules within 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 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.

2.5 UPS Control panel

The UPS Control panel contains four status LED indicators, an LCD display and a row of selection keys which include an ON/OFF key and three navigation keys. The navigation keys are used in conjunction with various monitoring and configuration menus.

2.5.1 Status LED indicators

The four LEDs located along the top of the UPS Control panel indicate the UPS operating status and may FLASH or remain constantly OFF or ON. Under some circumstances all five LEDs will illuminate in turn in a ‘rotating’ sequence.

The following table illustrates the LED states for various operating conditions – an ‘X’ indicates that the state is undefined and depends on the failure or warning mode.

Table 2.3 Status LED interpretation

2.5.2 LCD Display

A complete overview of the UPS operating status including the input, output, battery and load parameters is provided by the LCD display.

Under normal operating conditions the display shows white text on a blue back-light but under fault conditions this changes to dark text on an orange back-light, accompanied by an audible warning, as shown in the adjacent table.

Default Screen

During start up the LCD Display shows a ‘Welcome’ logo screen for around 5 seconds while the UPS initialises then changes to the ‘default status’ screen shown is Figure 2.10. The ‘default status’ screen is shown automatically during normal operation if the control panel keys are not operated for 15 minutes.

2: General Description

The default screen provides the following information:

• UPS input parameters – including an indication of the mains/bypass input voltage, and frequency

• UPS status – a symbolic indication of the UPS operating mode and fault/abnormal conditions. A list of status symbols is described in Table 2.5.

• Battery status – including the battery voltage and a graphical indication of the available battery charge

• Load status – graphical and numerical percentage indication of the connected UPS load

• UPS output – including an indication of output voltage, frequency and load power (W)

Default Screen status symbols

Table 2.5 Default Screen status symbols

Symbol Status Description

ON-LINE UPS is operating with the load supplied by the inverter.

ON BATTERY UPS is operating from battery power, usually due to a mains failure.

ON BYPASS UPS is operating with the load supplied from the bypass mains power.

Note: if there is a bypass supply failure while the UPS in on bypass, it will not transfer to ON LINE or ON-BATTERY mode unless it is operating in the ECO-mode – also known as High Efficiency (HE) mode.

ECO Mode (HE mode)

UPS is operating with the load supplied from the bypass mains power. In case of bypass mains failure, the UPS transfers to ON LINE mode or ON BATTERY mode and the load is supplied continuously.

ECO-mode can be enabled/disabled through the control panel Settings

menu or the UPS monitoring/control software.

CONVERTER mode UPS is set to operate with a different input and output frequency – either

50Hz-60Hz or 60Hz-50Hz. In case of input mains power failure, the bypass is inhibited and UPS transfers to ON BATTERY mode.

WARNING UPS is operating in the presence of an abnormal condition that does not

call for the UPS to be shut down. See the Troubleshooting chapter for details.

FAULT The UPS has experienced a fault condition. It may disconnect the load

or transfer the load to bypass depending on the type of failure. In all cases, there will be a constant alarm and the LCD back-light will become red. See the Troubleshooting chapter for details.

OVERLOAD UPS is overloaded. The load should be reduced to <90% of the UPS

rated capacity in order to stop the alarm.

BATTERY TEST UPS is performing a battery test.

If you plan to store the UPS cabinet prior to use it should be held it in a clean, dry environment with an ambient temperature between -5°C to +60°C (max +35°C for batteries) and RH <95%. 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.

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 UPS is designed for indoor installation only.

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

3. 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.

4. 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 0°C to +40°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.

5. 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) A minimum clearance of 50cm is required on the sides of the equipment to allow the free passage of cooling air

WARNING: Water condensation may occur if the UPS is unpacked in a very low temperature environment. In this case, you must wait until the UPS is fully dried inside and outside before proceeding with the installation to avoid possible electric shock hazard and equipment malfunction.

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, cool environment in their original packaging.

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

3.5.1 Clearances

The following notes are applicable to both the UPS and external battery cabinet.

The cabinet is force ventilated with extractor fans mounted on the back panel drawing cooling air through the inlet grills on the front of the unit. Sufficient space must be provided at the back and sides of the cabinet to permit adequate air-flow.

Rear access is required for connecting the power and control cables, and also to operate the UPS power switches. If direct rear access is not available, sufficient space must be provided at the side of the cabinet to allow the operator to reach around the cabinet to operate the power switches.

Note: Full access is required to both sides of

the cabinet for maintenance. The UPS cabinet is mounted on wheels, so if the installation does not afford direct side access the UPS connecting cables should be of sufficient length to allow the cabinet to be moved forward to offer unhindered side access when required.

We recommend the following minimum clearances:

• Rear access (X): a minimum of 500mm for unrestricted airflow

• Side (Y): a minimum of 500mm for free airflow, but may need increasing to 1000mm to afford rear access for

operating the equipment power switches if direct rear access is not available (see also the note above)

• Front (Z): allow a minimum of 1000mm for maintenance access and the safe passage of personnel

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 AC output 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.

and connected to the UPS at all times. DO NOT use, a 4ard on a TN-S system.

3.6.2 UPS Cable and fuse sizing

3.6.3 Power cabling for a parallel system

In order to achieve equal load sharing between the UPS cabinets in a parallel system, the length of the input cables from the input distribution board to each cabinet should be as equal as possible, with a maximum difference of 20%. This also applies to the UPS output cables. Each module should be connected to an output circuit breaker located on a switch panel no further than 20 meters from the cabinets.

External maintenance bypass

Figure 3.4 External bypass circuit

An external maintenance bypass facility, such as that shown in Figure 3.4, can be installed to increase the system flexibility. This circuit allows an individual module to be isolated from the system, for repair or total replacement, by opening its input fused isolator and Output Breaker. It also allows the total system to be bypassed by closing the System Bypass Breaker and opening the System Output Breaker; which in turn allows testing of the entire parallel system.

When such an external maintenance bypass is used it is crucial that the UPS modules are all operating on bypass (or internal maintenance bypass) before the System Bypass Breaker is closed, to avoid the possibility of module damage. For this reason it is usual to incorporate some form of safety interlocking mechanism around the external breakers.

Key Point: The information in figures 3.8 and 3.9 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 regulations: – e.g. BS7671: 2008 incorporating amendment No.1:2011.

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

3.6.4 UPS Terminal block connection details

The input, output and external battery power cables are connected to a terminal block rail located on the back of the UPS cabinet, behind a removable cover which is secured to the cabinet by four screws. Figure 3.5 shows the power terminal block connection details.

MAINS 1 – is connected to the UPS input mains supply and can be configured for either a single-phase or three-phase input supply.

MAINS 2 – is connected to the UPS bypass mains supply. This is a single-phase connection and it can either be linked to MAINS 1 (single input configuration) or connected to a dedicated bypass mains supply (dual input configuration). Note that the neutral connections for MAINS 1 and MAINS 2 are linked within the UPS.

The various MAINS 1 / MAINS 2 input configurations are described in paragraph

3.6.5

OUTPUT – The UPS AC output terminals

should be connected to the load distribution panel via a circuit breaker or fused isolator.

PARALLEL JP – JP1/JP2 is used to configure the UPS for parallel operation. By default, the UPS is shipped with a link connected between JP1 and JP2 which configures the UPS for use as a stand-alone unit (single module).

BATTERY – The battery terminals are used to connect the UPS cabinet to an external battery cabinet, where used.

3.6.5 Input/bypass supply configuration options

As mentioned above, the UPS input mains (MAINS 1) and bypass mains (MAINS 2) can be connected in several supply configurations. These can be described as:

• Three phase dual input – Three phase mains input (L1,L2,L3) and separate single phase bypass input (M2)

• Three phase single input – Three phase mains input (L1,L2,L3) with the bypass line (M2) linked to (L1)

• Single phase dual input – Single phase mains input (L1,L2,L3 linked) and separate single phase bypass line (M2)

• Single phase single input – Single phase mains input linked to the bypass input (L1,L2,L3,M2 all linked)

The input configuration is selected by fitting links to the power terminal block Mains 1 and Mains 2 connections. A ‘jumper kit’ comprising four screws, four spacers and a small busbar with 6holes, is shipped with the UPS module to enable the UPS input supply connections to be linked accordingly. When installed, the jumper bar should be fitted to connections along the centre of the terminal block with the spacers as shown in Figure 3.6 and secured firmly in place by the required screws. Link details for all four configurations are shown in figures 3.8 to 3.11).

Note: If only the three left-most screws are required to be fitted,

the bar can be cut to length.

CAUTION: If the UPS is to be installed as part of a parallel PW3000TP system the link between JP1-JP must be removed.

CAUTION: The UPS is usually shipped with its internal batteries already connected.

Safety notes

Please ensure you read and understand the following safety notes before you begin the UPS electrical installation.

1. Do not commence this procedure until the UPS mechanical installation has been completed.

2. All the cable installation procedures detailed below must be supervised by a qualified electrician.

3. Do not connect the UPS if there is water or moisture present.

4. When carrying out any work on the UPS power cables or terminals, you must ensure that the UPS input and output supplies are isolated and locked out at their respective distribution boards. Warning notices should be posted to prevent any inadvertent operation of the UPS mains supply isolators.

5. Once the electrical installation is completed the UPS must be commissioned by an engineer authorised by the manufacturer before it is brought into use.

6. When installing the UPS cables ensure that the connection procedures are performed under the following conditions:

a) No mains voltage is present at the UPS mains (or bypass) distribution board terminals. b) All loads are disconnected at the load distribution board and the UPS is fully shut down and voltage-free. c) The UPS Maintenance Bypass Isolator is open (OFF).

3.7.1 Power cabling procedure

Figure 3.7 Power terminal connections

To prepare for power cabling:

1. Remove the terminal block cover (1) to gain access to the terminal block connections.

2. All power cables enter the UPS through cable glands (2) fitted to the bottom of the terminal box. The holes used for the glands are fitted with blanks when the unit is shipped. Fit the supplied glands to suit the cable installation.

3. Connect the protective earth (GND) cables between the UPS power terminal block and each of the following:

a) input mains distribution panel b) bypass mains distribution panel (if separate) c) UPS output distribution panel d) external battery cabinet (if used)

4. Connect the power cables to the terminal block according to the desired input configuration, as described in Figure 3.8 to Figure 3.11.

WARNING: Opening or removing the UPS-covers will create a risk of exposure to dangerous voltages if power is connected to the UPS.

WARNING: Do not apply electrical power to the UPS before it has been commissioned.

Key Point: The power terminal block, shown in detail in Figure 3.5, can accept cables up to 16mm² in the 10kVA

unit. In the 20kVA unit the maximum terminal size is 35mm² but due to manipulation restrictions in the cable box we recommend using flexible cable with a maximum cable size of 25mm². Note that the input neutral and bypass neutral terminals are linked at the terminal block.

Key Point: The tables in Figure 3.8 to Figure 3.11 show the maximum current ratings for the cables and protective devices that must be provided by the customer. The chosen cables/protective devices must meet the required local standards and installed in accordance with codes of practice

TS_604_01 PowerWave PW3000/TP User Manual UK 5/1/18 37

4: Operating procedures

4.2 Single module start-up – with mains supply

Use this procedure to start a single module UPS system from a completely powered down condition.

1. Check that all the loads connected to the UPS are turned off.

2. Close the external UPS Input/bypass Isolators as required to connect power to the UPS.

3. If an external battery cabinet is used, close the fused isolator on the back of the battery cabinet together with any circuit breaker connected in the battery line.

4. On the back of the UPS cabinet, close the input breakers M1 and M2 (position ON).

a) The fans will start running. b) The UPS will perform a self-test and will then display the default screen on the LCD.

5. On the UPS Control Panel, press the ON/OFF key for more than one second.

a) The alarm buzzer will sound and the UPS will start. b) After a few seconds, the UPS will switch to its ‘on-line’ mode.

6. Check that the LCD indicates the ‘on-line’ status and no warning alarms are present.

7. The UPS is now fully operational and providing protected output power.

8. You can now switch on the loads. (If possible, turn on the loads sequentially to prevent a UPS overload occurring due to combined inrush currents.)

4.3 Single module start-up – without mains supply

If there is no mains supply present, you can use this procedure to start a single module UPS system using battery power (also described as a ‘cold start’).

1. Check that all the loads connected to the UPS are turned off.

2. Close the external UPS Input/bypass Isolators as required to connect power to the UPS.

3. If an external battery cabinet is used, close the fused isolator on the back of the battery cabinet together with any circuit breaker connected in the battery line.

4. On the back of the UPS cabinet, close the input breakers M1 and M2 (position ON).

a) Nothing will happen if the input supplies are not present.

5. On the UPS Control Panel, press the ON/OFF key for more than one second.

a) The fans will start running. b) The UPS will perform a self-test and will then display the default menu on the LCD.

6. Press the ON/OFF key again for more than one second.

a) The alarm buzzer will sound and the UPS will start. b) After a few seconds, the UPS will switch to its ‘on-battery’ mode.

7. Check that the LCD indicates the ‘on-battery’ status and no warning alarms are present other than those associated with the ‘battery on load’ status.

8. The UPS is now fully operational and providing protected output power, but the battery is on load and discharging (with the accompanying alarms).

9. You can now switch on the loads. (If possible, turn on the loads sequentially to prevent a UPS overload occurring due to combined inrush currents.)

a) If the UPS is left to run in this condition sufficiently long, the battery will fully discharge and the UPS will shut down

with the loss of the output supply.

b) If the mains supply is restored while the UPS is ‘on-battery’ it will automatically switch to ‘on-line’ mode.

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

As there are no user-serviceable parts contained within the UPS, the maintenance required by the user are minimal apart from keeping the equipment clean and monitoring the working environment to ensure it is kept cool and dust-free. This will maximise the useful working life and reliability of the UPS and its batteries.

5.4 Routine maintenance

It is essential that the UPS system and batteries receive regular preventative maintenance inspection. When the UPS is commissioned, the commissioning field service engineer will attach a service record book to 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 and should only be performed by authorised service personnel.

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 optional equipment

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

WARNING: The UPS contains hazardous voltages even when switched off. WARNING: Do not remove the UPS covers unless you are electrically qualified and trained on the

equipment type by the manufacturer (Uninterruptible Power Supplies Ltd) or one of its service agents.

WARNING: There are no user-serviceable part contained within the UPS. WARNING: Any operation described in this chapter that requires internal access to the UPS or external

battery cabinets must be performed by authorised service personnel.

5: Maintenance

48 TS_604_01 PowerWave PW3000/TP User Manual UK 5/1/18

5.5 Battery testing

The battery test takes approximately 3 minutes and should be performed only if:

• There are no alarm conditions

• The battery is fully charged

• The mains input supply is present

Battery testing can be performed from the Operator Control Panel and carried out independently of the operating mode (‘on-line’ or ‘on-bypass’) and whether or not the load is connected.

5.6 Battery maintenance

The UPS batteries should be replaced under the following conditions:

• If the battery service life (3~5 years at 25°C ambient temperature) has been exceeded

• When the discharging time is less than 50% of specified after full charged

When replacing the batteries, the complete battery string should be replaced with the same number and type of batteries. Individual batteries should not be replaced.

If the UPS is not used for a period of time the batteries should be charged at least every 4-6 months. When healthy, the batteries will charge to 80% in approximately 10 hours, however it is recommended that the batteries are charged for 48 hours after long term storage.

5.7 Battery disposal and recycling

Batteries contain dangerous substances that will harm the environment if carelessly discarded and should be disposed of in accordance with local recycling recommendations

TS_604_01 PowerWave PW3000/TP User Manual UK 5/1/18 49

Troubleshooting

6.1 Contacting Service

Please collect the following information before calling the After-Sales Service Department:

• UPS model number and serial number

• Date on which the problem occurred

• LCD/LED display information, buzzer alarm status

• Mains power condition, load type and capacity, environment temperature, ventilation condition

• Information on external batteries (battery capacity, quantity)

Uninterruptible Power Supplies Limited has a service department dedicated to providing routine maintenance and emergency service cover for your UPS. If you have any queries regarding your UPS please contact us.

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

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 FAIL alarm will activate and it may still indicate a fault condition even after the mains supply has returned to normal. Similarly, a LOAD ON BYPASS alarm might have been caused by an inverter overload

If any alarm appears, the first action to take is to attempt to RESET it.

If the alarm indication resets then it was probably caused by a transient condition; the UPS has responded correctly and no further action is required. Investigative action is necessary if it is not possible to reset the alarm, or if the alarm is repetitive, which may require assistance from the UPS Limited Service Department.
