If any internal fuse of the UPS is damaged, it must be replaced by professionals with a new one of the same specifications.
This equipment is fitted with radio frequency interference (RFI) suppression filters.
Earth leakage current exceeds 3.5mA and is less than 1000mA.
Transient and steady-state earth leakage currents, which may occur when starting the equipment, should be taken into
account when selecting instantaneous residual current circuit breaker (RCCB) or residual current detector (RCD) devices.
RCCBs must be selected insensitive to DC unidirectional pulses (Class A) and transient current pulses.
Note also that the earth leakage currents of the load will be carried by this RCCB or RCD.
This system has a signal available for use with an automatic device, externally located, to protect against backfeeding
voltage through the mains Static Bypass circuit. If this protection is not used with the switchgear that is used to isolate the
bypass circuit, a label must be added at the switchgear to advise service personnel that the circuit is connected to a UPS
system.
The text is the following or equivalent:
ISOLATE THE UNINTERRUPTIBLE POWER SYSTEM BEFORE WORKING ON THIS CIRCUIT.
As with other types of high power equipment, dangerous voltages are present within the UPS and battery enclosure. The
risk of contact with these voltages is minimized 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

This chapter briefly introduces the features, design concept and operation mode of the HIPULSE U UPS.
1.1 Features
The HIPULSE U UPS is connected between a critical load, such as a computer, and its 3-phase mains power supply.
Being designed to furnish a well regulated 3-phase output power supply under all rated load and input supply
conditions, the system offers the user the following advantages:
z 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.
z increased noise rejection
By rectifying the input AC power to DC power, and then converting it back to AC power, 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.
z 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.
Chapter 1 General Description 1
Chapter 1 General Description
1.2 Design Concept
1.2.1 HIPULSE U Module Design
This section describes the operating principle of an individual module. The UPS basically operates as an AC-DC-AC
converter (see Figure 1-1). The first conversion stage (from AC to DC) uses a 3-phase, fully controlled
silicon-controlled resistor (SCR) bridge rectifier to convert the incoming mains supply into a regulated DC busbar.
Bypass AC
supply
Rectifier
AC supply
The DC 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 integrated gate bipolar transistor (IGBT) switching space vector pulse width modulation (SVPWM) design – and
provides the second conversion phase, that is, reconverting the DC busbar voltage back into an AC voltage
waveform.
During normal operation, both the rectifier and inverter sections are active and provide regulated load power whilst
simultaneously 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 the battery is
fully discharged, whereupon the UPS shuts down. The end of battery discharge is assumed when the battery voltage
falls below a preset value (that is, 330Vdc for a 400Vac 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 through 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 line.

Battery
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.
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, that is, 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 (BCB) is also closed and the battery is therefore permanently float charged at the DC
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 synchronized 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 synchronization 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 returned within this time, the inverter will go off automatically and an alarm
message will appear on the operator control and display panel of the UPS.
Critical load will not be interrupted in the event of a drop or return of the AC power mains.

Chapter 1 General Description 3
Return of power mains
When the mains returns 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 steady-state 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, seek technical assistance from Emerson local customer service center.
(“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 bypass mains.
Overload
In the event of an overload at the inverter output which lasts longer than the typical time/current (refer to table 8-6),
the inverter will shut down and the static transfer switch will automatically transfer the load onto the 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 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 operator control and display panel of the UPS.
(“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 bypass mains supply, when the number of active modules is unable to satisfy load
requirements. The load returns to the inverter supply if the power is reduced to 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 trouble shooting. The circuit is manually selected by the maintenance
bypass switch in the OFF position.
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 breaking device is not present in the input distribution panel, there remains a dangerously high
voltage at the output busbars and also on the input busbars of the UPS module that is switched off.
1.2.4 ECO Mode (For Single UPS Only)
In ECO 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 (settable).
The ECO mode configuration requires a different setup in the default menu configuration.

Warning
4 Chapter 1 General Description
Operating procedures in ECO mode are the same as those described in Chapter 5 Operating Instructions, except
that the load is normally on the bypass mains, the Inverter LED is normally off, and the corresponding alarm message
Bypass mode will appear on the LCD.
In ECO mode the load is not protected against mains distortion.
1.2.5 UPS Power Switch Configuration
Figure 1-2 illustrates the HIPULSE U 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 (Q1) input supply connections would be linked together.
With the exception of the maintenance bypass switch, all the switches shown must be closed during normal UPS
operation.
1.2.6 Battery Circuit Breaker
The battery should be connected to the DC busbar through a circuit breaker fitted inside the battery cabinet — or
located adjacent to the 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.
Warning
1.2.7 Battery Temperature Compensation
HIPULSE U UPS system offers a battery temperature compensation circuit. As the temperature inside the battery
cabinet/area rises, the DC busbar voltage reduces in order to sustain the battery at its optimum charge voltage. This
must be used in conjunction with the battery temperature sensing device.
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 — up to a maximum of six UPS modules can be connected in parallel.
System expansion requires a change in the SETUP of the operator control and display panel of each UPS module.
Note:
1. System expansion should be carried out only by trained service personal.
2. The individual modules connected to the system must be of the same power rating.
1.3 Operation Mode
The UPS permits operation in the following alternative modes:
Normal mode
The UPS inverter continuously supplies the critical AC load. The rectifier/charger derives power from the AC mains
input source and supplies DC power to the inverter while simultaneously float or boost charging its associated backup
battery.
Battery mode
Upon failure of the AC mains input power, the critical AC load is supplied by the inverter, which obtains power from
the battery. There is no interruption in power to the critical load upon failure or restoration of the AC mains input
power after which the Normal mode operation will continue without the necessity of user intervention.
Note: Battery start device (optional) is available for switching the UPS on into Battery (charged) mode directly during
mains failure.

Chapter 1 General Description 5
Auto-restart mode
The battery becomes exhausted following an extended AC mains failure. The inverter shuts down when the battery
reaches the end-of-discharge voltage (EOD). The UPS can be programmed to Auto Recovery after EOD after a set
variable delay time. This mode and any delay time are programmed by the commissioning engineer.
Bypass mode
The load power is supplied though the mains static bypass line. This may be considered as an intermediate operating
condition being utilized for the purpose of load transfers between inverter and maintenance bypass or supply under
abnormal operating conditions.
Maintenance mode
The UPS is shut down but the load is connected to the unprotected mains through the maintenance bypass supply
line.
Source Share mode
The UPS has the capability of fully supporting their critical load while limiting the amount of power taken from the
incoming AC mains supply. Any balance of power required is supplied by the UPS battery. This feature is useful, for
example, in applications where peak-hour tariffs apply or where a generator smaller than needed feeds the UPS
during mains outages. The Source Share mode is user-activated and the ratio of the mains AC input power is
programmable from 20% to 100% of the rated UPS power.
ECO mode (for single UPS only)
All power switches and the BCB are closed, the system prefers to put the load on the bypass mains, with the inverter
on stand-by; only when the voltage and/or frequency of the bypass supply are beyond pre-defined and adjustable
limits is the critical AC load transferred to the inverter.
Parallel redundancy mode (system expa nsion)
For higher capacity or higher reliability or both, the outputs of up to six UPS modules can be programmed for directly
paralleling while a built-in parallel controller in each UPS ensures automatic load sharing.
Frequency converter mode
The UPS can be programmed into Frequency Converter mode for either 50Hz or 60Hz stable output frequency. The
input frequency may vary from 45Hz to 65Hz. In this mode, it is required to open the bypass switch to disable the
static bypass operation, and the battery becomes optional depending on any requirement to operate in Battery mode.

Special care should be taken when working with the batteries associated with this equipment. When connected together, the
battery terminal voltage will exceed 400Vdc and is potentially lethal.
1. Eye protection should be worn to prevent injury from accidental electrical arcs.
2. Remove rings , watches and all metal objects.
3. Only use tools with insulated handles.
4. Wear rubber gloves.
5. If a battery leaks electrolyte, or is otherwise physically damaged, it must be replaced, stored in a container resistant to sulfuric
acid and disposed of in accordance with local regulations.
6. If electrolyte comes into contact with the skin the affected area should be washed immediately with water.
The UPS system can be connected to an isolated neutral (IT) power system.
This chapter describes the environmental requirements and mechanical considerations that must be taken into
account when planning the positioning and cabling of the UPS equipment.
Because every site has its peculiarities, it is not the aim of this chapter to provide step-by-step installation instructions,
but to act as a guide as to the general procedures and practices that should be observed by the installing engineer.

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 Table 8-2).
All models in the HIPULSE U 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 in the cabinet roof.
When the cabinet is located on a raised floor, and bottom cable entry is used, additional cooling air also enters the
UPS through 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.
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 ECO mode 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 20°C. Operating above this temperature will reduce the battery life, and operation below this
temperature will reduce the battery capacity. On a normal installation the battery temperature is maintained between
15°C and 25°C. 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, and so on.
The batteries can be mounted in a 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 BCB must
be mounted as close as possible to the batteries themselves, and connected using the most direct route possible.
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, for example, UPS cabinet, battery cabinet. The 300kVA UPS (12-pulse rectifier) and 400kVA UPS
comprise a main cabinet and a side 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 suit.
2.3.2 Moving The Cabinets
Chapter 2 Mechanical Installation 7
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 of any handling equipment. See Table 8-3
for UPS weight details.
The UPS cabinet can be moved by fork lift. Before moving the UPS cabinet, it is necessary to remove both the front,
rear (or side) grille panels located at the base of the cabinet.
In the eventuality that the equipment cannot be moved by fork lift, then rollers should be used.
2.3.3 Clearances
As HIPULSE U UPS has no ventilation grills at either the sides or the rear, no clearances are required. However,
where space permits, a clearance of approximately 600mm at the back will ease access to magnetic component parts.
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 Of The Magnetic Components
Before the equipment is in place, remove the transportation restraints that hold the output transformer in place. For
procedures, refer to Appendix 1 Transportation Restraints Removing Procedures.
2.3.5 Cable Entry
Cables can enter for HIPULSE U 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.
Optionally a top cable entry extension may be used.
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 radius of the proposed cables to ensure that they can be fashioned to reach the
UPS connection busbars.

2.4 Preliminary Checks
Before you install the UPS hardware you should carry out the following preliminary checks:
1. Verify that the UPS room satisfies the environmental conditions stipulated in the equipment specification, paying
particular attention to the ambient temperature, air exchange system, and dust density.
2. Remove any packaging debris, visually examine the UPS and battery equipment for transit damage, both internally
and externally. Report any such damage to the shipper immediately.
