GENERAL

As with other types of high power equipment, dangerous voltages are present within
the UPS and battery enclosure. The risk of contact with these is minimised as the live
component parts are housed behind a hinged, lockable door. Further internal safety
screens make the equipment protected to IP20 standards.

No risk exists to any personnel when operating the equipment in the normal manner,
following the recommended operating procedures.

All equipment maintenance and servicing procedures involve internal access and
should be carried out only by trained personnel.

BATTERIES

Battery manufacturers supply details of the necessary precautions to be observed
when working on, or in the vicinity of a large bank of battery cells. These
precautions should be followed implicitly at all times.

Particular attention should be paid to the recommendations concerning local
environmental conditions and the provision of protective clothing, first-aid and fire
fighting facilities

TEST EQUIPMENT

When the battery is under charge, it is earth-referenced about its mid-point –e.g. if
the battery s being charged at 460V the battery extremities will be at +230V and –
230V with respect to neutral (earth). When using mains-powered test equipment
such as oscilloscopes in the UPS voltage area, always use a differential mode of
operation to disconnect the oscilloscope frame earth.

PERSONNEL

When working inside the UPS (trained personnel only) it is recommended that
protection be worn to prevent eye damage, should an electric ware be struck by
mishandling or severe electrical fault.

Some of the power components are very heavy. If their removal is necessary, ensure
that sufficient manpower is available; otherwise use adequate mechanical handling
equipment.

When working in the general area of the UPS where high voltages are present, a
second person should be standing-by to assist and summon help in case of accident.

CHAPTER 1

General Description

1.1 Introduction

The Hipulse Uninterruptible Power Supply (UPS) System is connected between a
critical load, such as a computer, and its three phase mains power supply. Being
designed to furnish a well regulated 1 phase output power supply under all rated load
and input supply conditions, the system offers the user the following advantages:

Increased power quality:

The UPS has its own internal voltage and frequency regulators which ensure that its
output is maintained within close tolerances independent of voltage and frequency
variations on the mains power lines.

Increased noise rejection:

By rectifying the input a.c. power to d.c. power, and then converting it back to a.c.,
any electrical noise present on the input mains supply line is effectively isolated from
the UPS output, therefore the critical load sees only clean power.

Power blackout protection:

If the mains power fails, the UPS continues to power the critical load from its battery
source, leaving the load immune from power disturbances.

1.2 Design Concept

1.2.1 Hipulse Module Design

This section describes an individual module's operating principles. The UPS basically
operates as an a.c. - d.c. - a.c. converter (see figure 1 -1 ). This first conversion stage
(from a.c. to d.c.) uses a 3 phase, fully-controlled SCR bridge rectifier to convert the
incoming mains supply into a regulated d.c. busbar.

Fig 1-1 : Single Module block diagram

The d.c. busbar produced by the rectifier provides both battery charging power ­being equipped with a temperature compensated battery charging system, to prolong
battery life - and power to the inverter section - which utilizes the latest IGBT switching
pulse width modulation (PWM) design - and provides the second conversion phase,
i.e. reconverting the d.c. busbar voltage back into an a.c. voltage waveform.

User Manual

Hipulse - Single Phase ‘1+N’ UPS System 130 kVA - 110V

During normal operation both the rectifier and inverter sections are active and provide
regulated load power whilst simultaneously float charging the battery. In the event of
a mains power failure, the rectifier becomes inoperative and the inverter is powered
solely from the battery. Critical load power is maintained under these conditions until
battery is fully discharged, where upon the UPS shuts down. The end of battery
discharge is assumed when the battery voltage falls below a preset value (i.e. 330 /
340V d.c. for a 400 V a.c. system).

The period for which the load can be maintained following a mains power failure is
known as the ‘System’s Autonomy Time’ and is dependent upon both the battery A/Hr
capacity and the applied percentage load.

1.2.2 Bypass Supplies

The circuit block annotated ‘Static Switch’ in figure 1-2 contains an electronically
controlled switching circuit which enables the critical load to be connected either to
the inverter output or to a bypass power source via the ‘static bypass line’. During
normal system operation the load is connected to the inverter and the ‘inverter -side’
of the Static Switch is closed; but in the event of a UPS overload, or inverter failure, it
is automatically transferred to the static bypass supply line.

Fig 1-2 : UPS Power switches configuration

To provide a clean (no-break) load transfer between the inverter output and static
bypass line, the static switch activates connecting the load to the bypass supplies. To
achieve this, the inverter output and bypass supply must be fully synchronized during
normal operating conditions. This is achieved through the inverter control electronics
which make the inverter frequency track that of the static bypass supply provided that
the bypass remains within an acceptable frequency window. The synchronizing
window is pre-selected to 2% of nominal frequency, giving an acceptable frequency
window ±1 Hz.

A manually controlled, ‘Maintenance Bypass’ supply is also incorporated into the UPS
design. Its purpose is to enable the critical load to be powered from the mains
(bypass) supply while the UPS is shut down for routine maintenance.

Note: The load equipment is not protected from normal supply aberrations when operating on Bypass
side or in the maintenance bypass mode

1.2.3 System Control Philosophy

Normal Operation

During normal operation, i.e. when the UPS input supply is present and within
specification, both the rectifier and inverter sections are active and the static switch is
turned on to connect the inverter output to the critical load busbars. The battery
circuit breaker is also closed and the battery is therefore permanently float charged at
the d.c. busbar voltage level.

(1+N Parallel UPS System)
Note: As the unit outputs are connected in parallel, the System checks that the inverter control circuits
are perfectly synchronised with one another and with the Bypass Mains in terms of both frequency and
phase and that they have the same output voltages. Current supplied to the load is automatically
divided among UPSs. A warning message appears while synchronisation is in progress.

A module's static switch cannot close until these conditions are satisfied.

Mains Failure

If the power mains has a failure or is out of tolerance the rectifier will go off
automatically, while the Inverter will continue to operate on power from the battery for
a period of time which depends on the load and the capacity of the battery. If the
mains supply has not retuned within this time, the Inverter will go off automatically and
an alarm message will appear on the UPS operator control panel display.

Critical load will not be interrupted in the event of a drop or return of the AC power
mains.

Return of power mains

When the mains return within the required tolerance, the Rectifier will start up again
automatically and gradually (power walk in), supplying power to the Inverter and
recharging the battery at the same time. There will be no interruption of the critical
load.

Off-Battery

If the battery system only is taken out of service for maintenance, it is disconnected
from the rectifier/ charger and inverters by means of (an) external disconnect
breaker(s). The UPS shall continue to function and meet all of the specified steady­state performance criteria, except for the power outage back-up time capability.

UPS Module fault

In the event of an Inverter fault, the Static Transfer Switch will automatically transfer
the load onto the Bypass Mains with no interruption. In such an event, request
qualified technical assistance.

(1+N Parallel UPS System)

In the event of a fault in a unit, the unit's Static Transfer Switch will automatically
exclude the unit from the system. If the system is still capable of providing the
required load, the remaining units will continue to supply the load with no interruption.
When the units still present in the system are no longer capable of fulfilling power
requirements, the load will automatically be transferred onto the MSS Bypass Mains.
The load will be transferred with no interruption if the Inverters are synchronised with
the network; if this is not the case, there will be an interruption lasting about 20
milliseconds.

User Manual

Hipulse - Single Phase ‘1+N’ UPS System 130 kVA - 110V

Overload

In the event of an overload at the Inverter output which lasts longer than the typical
time/ current (refer to Chapter 9 - Specifications), the Inverter will shut down and the
Static Transfer Switch will automatically transfer the load onto the MSS Bypass Mains
with no interruption. If the overload falls within the typical time/ current that has been
specified, the load will be returned to the inverters when the power drops to a level
which can be supported by the number of active units in the system (parallel 1+N).

In the event of a short circuit in the output, the load will normally be transferred onto
the MSS Bypass Mains, which will cause the Inverter to shut down; this switch is
determined above all by the features of the protective devices in use in the system. In
either case, an alarm message will appear on the UPS operator control panel display.

(1+N Parallel UPS System)

The control logic system constantly monitors load requirements and controls the
power supplied by the UPS modules. In the event that an overload condition is
sustained for greater than a preset time, the load will transfer to the mains bypass
supply, when the number of active modules are unable to satisfy load requirements.
The load returns to the inverter supply if the power is reduced it a value that can be
sustained by the number of active modules in the system.

Maintenance Bypass

A second bypass circuit contained in the UPS cabinet, identified as the 'Maintenance
Bypass' line is included to enable a 'raw' mains supply to be made available to the
load while facilitating a safe working environment for carrying out scheduled UPS
system maintenance or troubleshooting. The circuit is manually selected by the
Maintenance Bypass Isolator which can be padlocked in the OFF position.

WARNING

The internal maintenance bypass must not be used when the UPS
system is comprised of more than two UPS modules in parallel.

CAUTION

If an automatic circuit breaker device is not present in the input
distribution panel, there remains a dangerously high voltage at the
output busbars of the UPS module that is switched off

1.2.4 ECOMODE

In this operating mode the System prefers to put the load on the Bypass Mains, with
the Inverter on stand-by. The load is switched over to the Inverter when the mains
goes outside of standard frequency and voltage values (or the values as modified
using the operator panel when starting up the system). The ECOMODE configuration
requires a different setup in the default menu configuration, which may be prepared in
the factory before shipment or during installation by personnel trained in the use of the
System.

Note: In order to operate in ECOMODE, UPSs must be provided with compatible software versions:

The 'UPS Logic' card must be release 9.0 or later (the S/W release of the cards may be
read on the front panel display, referring to Section 4.1.2 - Operating Instructions).

Operating Instructions in ECOMODE are the same as those described in Chapter 5,
except that the load is normally on the Bypass mains, the Load LED is normally on
Inverter (5), and corresponding alarm message will be replaced with Load on Mains
(6).

User Manual

Hipulse - Single Phase ‘1+N’ UPS System 130 kVA - 110V

WARNING

In ECOMODE the load is not protected against mains distortion.

1.2.5 UPS Power Switch Configuration

Figure 1-2 illustrates the Hipulse UPS module in what is known as the "Split Bypass"
configuration. In the Split Bypass configuration, the static bypass line is connected by
a separate power switch to a dedicated 'bypass' power source which also feeds the
maintenance bypass line. Where a separate power source is not available the Bypass
(Q2) and Rectifier input supply connections would be linked together.

With the exception of maintenance bypass isolator, all the isolators shown must be
closed during normal UPS operation.

1.2.6 Battery circuit breaker

The battery should be connected to the d.c. busbar through a circuit breaker fitted
inside the battery cabinet or located adjacent to batteries where a battery cabinet is
not used. This circuit breaker is closed manually, but it contains an undervoltage
release coil which enables it to be tripped from the UPS control electronics following
certain detected faults. It also has a magnetic trip facility for overload protection.

1.2.7 Battery temperature compensation

Hipulse UPS System offers a battery temperature compensation circuit. As the
temperature inside the battery cabinet area rises, the d.c. busbar voltage reduces in
order to sustain the battery at its optimum charge voltage. This must be used in
conjunction with the battery sensor board.

1.2.8 System Expansion

If necessary, a single -module system can be expanded to cater for an increased load
requirement by adding additional modules - upto a maximum of six UPS modules can
be connected in parallel. System expansion requires change in the SETUP of the
display panel.

Note: System expansion should be carried out only by trained service personal. The individual
modules connected to the system must be of the same power rating

Installation Procedure

2.1 Introduction

WARNING

Do not apply electrical power to the UPS equipment before the
arrival of the commissioning engineer.

WARNING

The UPS equipment should be installed by a qualified engineer in
accordance with the information contained in this chapter and all
equipment not referred to this manual is shipped with the details its
own mechanical and electrical installation.

WARNING - Battery Hazards

• Special care should be taken when working with the batteries

associated with this equipment. When connected together, the
battery terminal voltage will exceed 400V DC, and is potential
lethal.

• Eye protection should be worn to prevent injury from accidental

electrical arcs.

• Remove rings, watches and all metal objects.

• Only use tools with insulated handles.

• Wear rubber gloves.

• If a battery leaks electrolyte, or is otherwise physically damaged, it

must be replaced, stored in container resistant to sulfuric acid and
disposed of in accordance with local regulations.

• If electrolyte comes into contact with the skin, the affected area

should be washed immediately with water.

NOTE

2.2 Environmental considerations

2.2.1 UPS location

The UPS module should be located in a cool, dry, clean-air environment with
adequate ventilation to keep the ambient temperature within the specified operating
range (see Chapter 9 - Specifications).

All models in the ‘Hipulse’ UPS range are cooled with the aid of internal fans. Cooling
air enters the module through ventilation grills located at various parts of the cabinet
and exhausted through grills located on the back of UPS. When the cabinet is located
on a raised floor, and bottom cable entry is used, additional cooling air also enters the
UPS via the floor void. If necessary, a system of extractor fans should be installed to
aid cooling air-flow, and a suitable air filtration system used where the UPS is to
operate in a dirty environment.

Note 1: When batteries are cabinet-mounted adjacent to the UPS module, it is the battery which
dictates the designed maximum ambient temperature, not the UPS.

Note 2: Power losses from the System which may be used in an air conditioning system are intended
for operation using the Inverter, as in the ECOMODE configuration they would be undersized.

2.2.2 Battery location

Temperature is a major factor in determining the battery life and capacity. Battery
manufacturers quote figures for an operating temperature of 20oC. Operating above
this temperature will reduce the battery life, operation below this temperature will
reduce the battery capacity. On a normal installation the battery temperature is
maintained between 15oC and 25oC. Batteries should be mounted in an environment
where the temperature is consistent and even over the whole battery. Keep batteries
away from main heat sources or main air inlets etc.

The batteries can be mounted in purpose-built battery cabinet, which is positioned
adjacent to the UPS module. Pedestals are required for the battery cabinets when
they are located on raised floors, in the same way as for the UPS cabinets. If the
batteries are rack-mounted, or otherwise located remote to the main UPS cabinet, a
battery circuit breaker must be mounted as close as possible to the batteries
themselves, and connected using the most direct route possible. A customized
remote battery circuit breaker box, containing the circuit breaker and its necessary

2.3 Mechanical Considerations

2.3.1 System composition

A UPS system can comprise a number of equipment cabinets, depending on the
individual system design requirements - e.g. UPS cabinet, Battery cabinet. In general,
all the cabinets used in a particular installation are of the same height and designed to
be positioned side-by-side to form an aesthetically appealing equipment unit.

2.3.2 Moving the cabinets

WARNING

Ensure that any lifting equipment that used in moving the UPS
cabinet has sufficient lifting capacity.

Ensure that the UPS weight is within the designated surface weight loading
(Kg/sq.cm.) of any handling equipment. See the UPS specification for weight details.

The UPS cabinets can be moved by fork lift or crane. For operations with fork lift, it is
necessary to remove both the front, rear (or side) grille panels located on the base of
the cabinet. To enable the cabinet to be lifted by a crane, removable lifting bars, are
fitted to the top of the cabinet.

In the eventuality that the equipment cannot be moved by fork lift or crane, then rollers
should be used.

2.3.3 Clearances

As Hipulse has no ventilation grills at either the sides or the rear, no clearances are
required. Back -access is not an essential requirement for maintenance; however,
where space permits, a clearance of approximately 1000mm will ease access to
magnetic component parts. This will also ensure proper exhaust from rear.
Clearance around the front of the equipment should be sufficient to enable free
passage of personnel with the doors fully opened.

2.3.4 Fixing magnetic components

After the equipment is in place, remove the transportation restraints that hold the
output transformer in place.

2.3.5 Cable entry

Cables can enter for ‘Hipulse’ UPS and battery cabinet either from below or through
either side. Side entry is made possible by removing blanking pieces fitted in the side
panel to reveal the cable entry holes. This cable entry method allows the equipment
to be positioned on a solid floor without the need for cable trenching and allows
cables to pass from one module to the other when positioned side-by-side.

Note: When selecting the power cables for side entry to a module located on a solid floor,
consideration must be given to the minimum permissible bending radius of the proposed cables to
ensure that they can be fashioned to reach the UPS connection busbars.
