This product complies with CE73/23 & 93/68 (low voltage safety) and 89/336 (EMC), and the following UPS product standards: *IEC62040-1-1-General and safety requirements for use in operator access area *IEC/EN62040-2 EMC requirements CLASS C *IEC62040-3 Performance requirements and test methods For more details, refer to Chapter 9 . Continued compliance requires installation in accordance with these instructions and the use of manufacturer approved accessories only.

WARNING: high earth leakage current

Earth connection is critical before connecting the input supply (include both utility supply and battery). "Earth leakage current introduced by the UPS, in any configuration from 10kW to 150kW, exceeds 3.5 mA and is less than 1000 mA and complies with the requirements of IEC/EN 62040-1 / IEC/EN 60950-1" Transient and steady-state earth leakage currents, which may occur when starting the equipment, should be taken into account when selecting instantaneous RCCB or RCD devices. Residual Current Circuit Breakers ( RCCBs) must be selected sensitive to DC unidirectional pulses (class A) and insensitive to transient current pulses. Note also that the earth leakage currents of the load will be carried by this RCCB or RCD. This equipment must be earthed in accordance with local electrical authority codes of practice.

WARNING: backfeeding protection

This system has a control 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 to the switchgear to advise service personnel that the circuit is connected to a UPS system. The text has the following meaning or is equivalent to: Isolate the UPS before working on the circuit of this UPS.

Components that can be maintained by user

All the equipment maintenance and servicing procedures involving internal access need special tools and should be carried out only by trained personnel. The components that can only be accessed by opening the protective cover with tools cannot be maintained by user. This UPS full complies with “IEC62040-1-1-General and safety requirements for use in operator access area UPS”. Dangerous voltages are present within the battery box. However, the risk of contactor with these high voltages is minimized for non-service personnel. Since the component with dangerous voltage can only be touched by opening the protective cover with a tool, the possibility of touching high voltage component is minimized. No risk exists to any personnel when operating the equipment in the normal manner, following the recommended operating procedures in this manual.

Chapter 1 Installation

1.1 Introduction

This chapter introduces the relevant requirements for positioning and cabling of the Modular UPS and related equipment. Because each site has its requirements, it is not the aim of this chapter to provide step-by-step installation instructions, but to act as a guide for the general procedures and practices that should be observed by the installing engineer.

Warning: installation can only be done by authorized engineers

Do not apply electrical power to the UPS equipment before the commissioning engineer arrives at installation site. The UPS should be installed by a qualified engineer in accordance with the information contained in this chapter. All the equipment not referred to in this manual is shipped with details of its own mechanical and electrical installation information.

Note: 3-Phase 4-Wire Input Power is required

The standard UPS system can be connected to TN, TT AC distribution system (IEC60364-3) of 3-phase 4-wire, and a 3wire to 4-wire conversion transformer is provided as an optional part. 1-phase 3-wires is also provided as an optional part.

WARNING: battery hazards

SPECIAL CARE SHOULD BE TAKEN WHEN WORKING WITH THE BATTERIES ASSOCIATED WITH THIS EQUIPMENT. When connecting the battery, the battery terminal voltage will exceed 400Vdc and is potentially 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 a container

resistant to sulfuric acid and disposed of in accordance with local regulations.

 If electrolyte comes into contactor with the skin, the affected area should be washed immediately with water.

1.2 Initial Checking

Perform the following checking operations prior to the UPS installation.

1. Visually examine if there is any damage inside and outside the UPS rack and battery equipment due to the transportation. Report any such damage to the shipper immediately.

2. Verify the product label and confirm the correctness of the equipment. The equipment label is attached on the back of front door. The UPS model, capacity and main parameters are marked on the label.

1.3 Location

1.3.1 UPS Location

The UPS is intended for indoor installation and should be located in a cool, dry and clean environment with adequate ventilation to keep the environmental parameters within the specified operating range (see Table.9-2).The Modular series UPS uses forced convection cooling by internal fans. Cooling air enters the module through ventilation grills located at the front part of the cabinet and exhausted through grills located in the rear part of the cabinet. Please do not block the ventilation holes.

Chapter 1 Installation

2 Shield M10U user manual

If necessary, a system of extractor fans should be installed to aid cooling-air flow. An air filter should be used when the UPS is to operate in a dirty environment and should be regularly cleaned to maintain airflow. The cooling capacity of air conditioner should be selected according to the power loss data of UPS specified in Table.9-8: Normal mode (VFI SS 111 double-conversion UPS) Note: The UPS should be installed on a cement surface or other surface that is not combustible.

1.3.2 External Battery Room

The battery will generate some amount of hydrogen and oxygen at the end of charging, so the fresh air volume of the battery installation environment must meet EN50272-2001 requirements. The ambient temperature of the battery must be stable. Ambient temperature is a major factor in determining the battery capacity and life. The nominal operating temperature of battery is 20°C. Operating above this temperature will reduce the battery life, and operation below this temperature will reduce the battery capacity. If the average operating temperature of battery is increased from 20ºC to 30ºC, then the service life of the battery will be reduced by 50%. If the operating temperature of the battery is above 40ºC, then the battery service life will be decreased in exponent rate. In a normal installation, the battery temperature is maintained between 15°C and 25°C. Keep batteries away from heat sources or air outlets. If external batteries are to be used, the battery circuit breakers (or fuses) must be mounted as close as possible to the batteries, and the connecting cables should be as short as possible.

1.3.3 Storing

Should the equipment not be installed immediately, it must be stored in a room so as to protect it against excessive humidity and heat sources (see Table.9-2).The battery needs to be stored in dry and cool place with good ventilation. The most suitable storage temperature is 20 ºC to 25ºC.

Preventing battery deep discharge

Should the UPS remains unpowered for a prolonged period of time while the battery are connected, the batteries may deeply discharge and being so permanently damaged .In such cases it is therefore recommended to leave the battery circuit breaker(s) open. During storage in any case, periodically charge the battery according to the battery user manuals.

1.4 Positioning

When the equipment has been finally positioned, ensure the UPS will remain stationary and stable. To prolong the service life, the place chosen must guarantee:

 Space for easy operation on the UPS  Air sufficient enough to dispel heat produced by UPS  Against atmospheric agents  Against excessive humidity and heat sources  Against dust  With the current fire prevention requirements  The operating environment temperature is within +20°C to +25°C. The batteries are at maximum efficiency in this

temperature range (for information about the battery storage and transportation as well as the environment, refer to Table.9-2 )

 This equipment is of steel frame structure wrapped by removable panels. The top and side panels are fixed by

screws.

 After opening the UPS rack door, the auxiliary connections for external low voltage interface and the maintenance

bypass can be accessed. The UPS rack has an operator and control panel located on its front door, which provides the basic operating status and alarm information. Batteries are external. The UPS provides air inlet port in the front and the air exhaust port in the rear part.

1.4.1 System Cabinet

A UPS system can comprise an UPS rack system, external battery cabinet, depending on the specific system requirement. All the UPS system cabinets used in the same installation site are of the same height and should be positioned side-by-

警告

危险

Page 12

Chapter 1 Installation

Shield M10U user manual 3

side to achieve an aesthetically appealing effect. Refer to Chapter 7 Installation Drawing for the positioning of UPS cabinet.

1.4.2 Moving the Cabinets

Warning

Ensure that any lifting equipment used in moving the UPS cabinet has sufficient lifting capacity. The UPS is fitted with castors – take care to prevent movement when unbolting the equipment from its shipping pallet. Ensure adequate personnel and lifting aids are available when removing the shipping pallet.

Ensure that the UPS weight is within the weight loading capacity range of any hoisting equipment. See Table.9-3 for UPS weight. UPS and optional cabinets can be handled by means of a fork lift or similar equipment. The UPS cabinet can also be moved by its castors when moving in a short distance.

Note: Care must be taken when handling units fitted with batteries. Keep such moves to a minimum.

1.4.3 Clearances Required for Operating

As rack module UPS has no ventilation grills at either sides, no clearances are required for the sides. To enable routine tightening of power terminations within the UPS, it is recommended that clearance around the front of the equipment should be sufficient to enable free passage of personnel with the doors fully opened. It is important to leave a distance of 500mm in the rear side of the rack to permit adequate circulation of air coming out of the unit. If the UPS make use of internal modular battery sufficient clearing shall be given at the back site to allow personnel to operate the battery circuit breakers

1.4.4 Front Access

The component layout of the UPS rack system supports front access and repairing the UPS, thus reducing the space requirement for side access.

1.4.5 Final Positioning

When the equipment has been finally positioned, ensure the adjustable feet are set so that the UPS will remain stationary and stable.

1.4.6 Installation of Adjustable Feet

Installation diagrams in Chapter 4 of this manual identify the location of the holes in the base plate through which the equipment can be bolted to the floor. If the UPS is to be located on a raised floor, it should be mounted on a pedestal suitably designed to accept the UPS point loading (more than 150 kg).

1.5 External Protective Devices

For safety concerns, it is necessary to install external circuit breakers or other protective devices for the input AC supply of the UPS system. This section provides generic practical information for qualified installation engineers. The installation engineers should have the knowledge of the regulatory wiring standards, and of the equipment to be installed.

1.5.1 Rectifier and Bypass Input Supply of the UPS

Over currents

Install suitable protective devices in the distribution unit of the incoming mains supply, considering the power cable current-carrying capacity and overload capacity of the system (see Tab. 9-7). Generally, the magnetic circuit breaker with IEC60947-2 tripping curve C (normal) at the 125% of the current listed in Tab. 9-7 is recommended. Split bypass: In case a split bypass is used, separate protective devices should be installed for the rectifier input and bypass input in the incoming mains distribution panel. Note: The rectifier input and bypass input must use the same neutral line. Protection against earth faults (RCD devices): The RCD device installed upstream of the input supply should:

Sensitive to DC unidirectional pulses (class A) in the network Insensitive to transient current pulses Have an average sensitivity that is adjustable between 0.3A and 1A.

Fig.1- 5: The Symbols of RCCB

When using the RCD in the split bypass system or parallel system, the RCD should be installed in the upstream of the input distribution to avoid wrong alarm. The residual current introduced by RFI filter in the UPS is between 3.5mA and 1000mA. It is recommended to confirm the sensitivity of each RCD of upstream input distribution and downstream distribution (to load).

1.5.2 External Battery

The DC compatible circuit breaker provides over current protection for UPS system and battery, which is provided by the external battery cabinet.

1.5.3 UPS Output

In the eventuality that an external distribution panel is used for load distribution, the selection of protective devices must provide discrimination with those that are used at the input to the UPS (see Tab. 9-7).

1.6 Power Cables

Design the cables according to the descriptions in this section and local regulatory wiring standards, and the environmental conditions (temperature and physical support media) should be taken into consideration. Refer to IEC60950-1 Table 3B Cabling.

WARNING

FAILURE TO FOLLOW ADEQUATE EARTHING PROCEDURES CAN RESULT IN EMI, ELECTRIC SHOCK HAZARD, OR RISK OF FIRE, SHOULD AN EARTH FAULT OCCUR.

2. Take special care when determining the size of the output and bypass neutral cable, as the current circulating on the neutral cable may be greater than nominal current in the case of non-linear loads, which is usually 1.732 times of rated currents.

3. The earth cable connecting the UPS to the main ground system must follow the most direct route possible. The earth conductor should be sized according to the fault rating, cable lengths, type of protection, etc. According to AS/IEC60950-1, the cross section area of the conductor is 16mm2/10mm2 (40 input/output), the cross section area of the conductor is 10mm2/6mm2 (10/20KVA input/output), the cross section area of the conductor is 35mm2/25mm2 (60kVA input/output).

4. When sizing battery cables, a maximum volt drop of 4Vdc. is permissible at the current ratings given in Table.1-2. The load

equipment is connected to a distribution network of individually protected busbars fed by the UPS output rather than connected directly to the UPS. In parallel multi-module systems, the output cable of each ups rack unit should be kept at equal length between the output of the ups rack output terminals and the parallel distribution busbars to avoid affecting the shared current. When laying the power cables, do not form coils, so as to avoid the formation of electromagnetic interference.

5. See Chapter 4 Installation Drawing for the positions of wiring terminals.

Chapter 2 Battery Installation and Maintenance

2.1 General Recommendations

Take special care when operating the batteries of the Modular UPS system. When all the battery cells are connected, the battery voltage can exceed 400Vdc, which is potentially lethal.

Note

The precautions for battery installation, use and maintenance are to be provided by the batteries manufacturers. The precautions in this section include the key issues that must be considered during the installation design, which may be adjusted according to the specific local situations. Battery Room Design

 The battery shall be installed and stored in a clean, cool and dry environment.  Do not install the battery in a sealed battery chamber or sealed room. The battery room ventilation shall at

least meet the requirement of EN50272-2001. Otherwise, battery bulging, fire and even human injury may be caused.

 The battery shall be installed far away from the heating source (e.g. transformer). Do not use or store the

battery in the place near the heating source or burn the battery or place it into fire. Otherwise, battery leakage, bulging, fire or explosion may be caused.

 Batteries shall be placed in such a manner that two bare live parts with the potential difference of more than

150V shall not be contactored at the same time. If it is unavoidable, insulated terminal cover and insulated cables shall be used for connection.

 If external batteries are to be used, the battery circuit breakers (or fuses) must be mounted as close as possible

to the batteries, and the connecting cables should be as short as possible.

Battery Handling

When connecting the battery, follow the precautions for high-voltage operation

 Before accepting and using the battery, check the appearance the battery. If the package is damaged, or the

battery terminal is dirty, corroded or rusted or the shell is broken, deformed or has leakage, replace it with new product. Otherwise, battery capacity reduction, electric leakage or fire may be caused.  Before operating the battery, remove the finger ring, watch, necklace, bracelet and any other metal

jewelry

 Wear rubber gloves.  Eye protection should be worn to prevent injury from accidental electrical arcs.  Only use tools (e.g. wrench) with insulated handles.

 The batteries are very heavy. Please handle and lift the battery with proper method to prevent any human

injury or damage to the battery terminal.

 Do not decompose, modify or damage the battery. Otherwise, battery short circuit, leakage or even human

injury may be caused.

 The battery contains sulfuric acid. In normal operation, all the sulfuric acid is attached to the separation board

and plate in the battery. However, when the battery case is broken, the acid will leak from the battery. Therefore, be sure to wear a pair of protective glasses, rubber gloves and skirt when operating the battery. Otherwise, you may become blind if acid enters your eyes and your skin may be damaged by the acid.

 At the end of battery life, the battery may have internal short circuit, drain of electrolytic and erosion of

positive/negative plates. If this condition continues, the battery may have temperature out of control, swell or leak. Be sure to replace the battery before these phenomena happen.

 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.

 If electrolyte comes into contactor with the skin, the affected area should be washed immediately with water.

2.2 Battery Typologies

According to the requested configuration UPS may need batteries consisting of one or more strings of battery blocks installed on shelves in a locked cabinet or dedicated battery room

Note

The Traditional external battery cabinet can make use of each even number of battery per string between 36 and

44. The default factory setting, if the unit is ordered w/o internal battery is 40. The cabinet is only for valve regulated maintenance-free lead-acid battery.

CAUTION: The lead acid battery may cause chemistry hazard

2.2.1 Traditional Battery Installation

Only the qualified engineers are allowed to install and maintain mounted in a traditional battery cabinet or shelf. To ensure safety, install the external battery in a locked cabinet or dedicated battery room accessible just to service qualified personnel. Please note that number of cells set via software must be consistent with the actual number of cells. A minimum space of 10mm must be reserved on all vertical sides of the battery block to permit free air movement around the cells. A certain clearance should be reserved between the top of the cells and the underside of the shelf above as this is necessary for monitoring and servicing the cells. When installing the batteries always work from the bottom shelf upwards to prevent raising the center of gravity. Install the batteries reliably and avoid vibration and mechanical bumping. The bending radius of cable should be more than 10D, where "D" is the outer diameter of cable. When connecting the cable, do not cross the battery cables and do not bind the battery cables together. The battery connection must be firm and reliable. After the connection, all the connections between the wiring terminals and the batteries must be corrected to meet the torque requirement provided in the specifications and user manuals of the battery manufacturers. Each battery terminal should be insulated after its connection has been made. Check if the battery is unexpectedly grounded. If the battery is unexpectedly grounded, remove the earth power supply. Contactoring any part of the grounded earth may be subject to electric shock. Measure the battery voltage and carry out battery voltage calibration after the UPS is started. Diagram of batteries connection is shown as below:

 When connecting the cables between the battery terminals and the circuit breaker, always connect the circuit

breaker end of the cable first.

 Be sure to connect the positive/negative terminals of the batteries to those of the circuit breakers and those

of the circuit breakers to those of the UPS respectively with reference to the markings of positive/negative terminals. Reverse connection of battery polarities will result in explosion, fire accident, the damage of batteries and UPS, and human injury.

 The battery connecting terminal shall not subject to any external force, such as the pulling force or twisting

force of the cable. Otherwise, the internal connection of the battery may be damaged, and in severe case, the battery may catch fire.

 Do not connect power until the total voltage of the battery string is verified correct through measurement.  Do not connect any conductor between the positive and negative terminals of the battery.  Do not close the battery circuit breakers before getting the approval from the commissioning engineer.

2.3 Battery Maintenance

For the battery maintenance and precautions, please refer to IEEE-Std-1188-2005 and the relevant manuals provided by the battery manufacturers.

Battery Maintenance Note

 Check to ensure that all the safety devices are in place and function normally. Check if the battery

management parameter setting is normal particularly.

 Measure and record the air temperature in the battery room.  Check if the battery terminals are damaged or have the symptom of heating, and if the shell or cover is

damaged.

 Please fasten every bolt on the terminal according to the fastening torque specified in the table below.  After 1-2 months of service, recheck to make sure that each screw has been fastened according to the specified

torque. Otherwise there is risk of fire.

 CAUTION: Use the battery with the same capacity and type, if battery is replaced by an incorrect type, it can

cause explosion.

5.1 Introduction

The Modular UPS rack system provides the critical load (such as communication and data processing equipment) with high quality uninterruptible AC power. The power from the UPS is free from voltage and frequency variations and disturbances (interruption and spike) experienced at the Mains AC input supply. This is achieved through high frequency double conversion power pulse width modulation (PWM) associated with fully digital signal processing control (DSP), which features high reliability and convenience for use. As shown in fig.5-1, the AC input mains source is supplied at UPS input and converted into a DC source. This DC source feeds the Inverter that converts the DC source into a clean and input independent AC source. The battery powers the load through the inverter in case of an AC input mains power failure. The utility source can also power the load through the static bypass. When the UPS needs maintenance or repair, the load can be transferred to maintenance bypass without interruption and the power module and bypass module can be removed for maintenance.

5.1.1 Split-Bypass Input

Fig. 5-1 illustrates the Modular UPS in what is known as the split-bypass configuration (that is, the bypass uses a separated AC power). In this configuration, the static bypass and maintenance bypass share the same independent bypass power supply and connect to the power supply through a separate switch. Where a separated power source is not available, the bypass and rectifier input supply connections are linked.

5.1.2 Static Transfer Switch

The circuit blocks labeled Static Switch in fig.5-1 contain electronically controlled switching circuits that enable the critical load to be connected to either 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; but in the event of a UPS overload or inverter failure, the load is automatically transferred to the static bypass line. To provide a clean (no-break) load transfer between the inverter output and static bypass line, the inverter output and bypass supply must be fully synchronized during normal operating conditions. This is achieved through the inverter control electronics, which makes 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 incorporated into the UPS design. It enables the critical load to be powered from the utility (bypass) supply while the UPS is shut down for routine maintenance.

Note

When the UPS is operating in bypass mode or on maintenance bypass, the connected equipment is not protected from power failures or surges and sags.

5.2 1+1 Parallel System

Several “single unit” UPS modules may constitute a “1+1” system, where up to two single units operate together for the purpose of providing additional power or reliability or both. The load is equally shared between any paralleled UPSs.

5.2.1 Features of Parallel System

1. The hardware and firmware of single module UPS units are completely compatible with the requirements of a parallel system. Parallel configuration can be achieved merely through settings in configuration software. The parameters settings for the modules in parallel system shall be consistent.

2. Parallel control cables are connected in a ring, providing both performance and redundancy. Dual-bus control cables are connected between any two UPS modules of each bus. The intelligent paralleling logic provides the user with maximum flexibility. For example, shutting down or starting up UPS modules in a parallel system can be done in any sequence. Transfers between Normal and Bypass modes of operation are synchronized and self–recovering e.g. following overloads and their clearance.

3. The total load of the parallel system can be queried from each unit’s LCD.

5.2.2 Parallel Requirements of UPS Modules

A group of paralleled modules behave as if it were one large UPS with the advantage of presenting higher reliability. In order to assure that all modules are equally utilized and to comply with relevant wiring rules, the following requirements apply:

1. All UPS modules shall be of the same rating and must be connected to the same bypass source.

2. The bypass and the main input sources must be referenced to the same neutral potential.

3. Any RCD (Residual Current detecting device), if installed, must be of an appropriate setting and located upstream of the common neutral bonding point. Alternatively, the device must monitor the protective earth currents of the system. Refer to the High Leakage Current Warning in the first part of this manual.

4. The outputs of all UPS modules must be connected to a common output bus.

5. It is strongly recommended that each paralleled UPS install at least a redundant power module

1. Optional isolation transformers are available for applications where sources do not share the same neutral

reference or where the neutral is not available.

2. Parallel system is available only for 6 power modules cabinet.

5.3 Operating Mode

The Modular UPS is an on-line, double-conversion, reverse-transfer UPS that permits operation in these modes:

 Normal mode  Battery Mode  Auto-restart mode  Bypass mode  Maintenance mode (manual bypass)  Parallel redundancy mode(6 modules cabinet)  ECO Mode

5.3.1 Normal Mode

The UPS inverter power modules 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.

5.3.2 Battery Mode

Upon failure of the AC mains input power; the inverter power modules, which obtains power from the battery, supplies the critical AC load. There is no interruption in power to the critical load upon failure. After restoration of the AC mains input power, the “Normal Mode” operation will continue automatically without the necessity of user intervention.

5.3.3 Auto-Restart Mode

The battery may become exhausted following an extended AC mains failure. The inverter shuts down when the battery reaches the End of Discharge voltage (EOD). The UPS may be programmed to “Auto Recovery after EOD” after a delay time if the AC mains recovers. This mode and any delay time are programmed by the commissioning engineer.

5.3.4 Bypass Mode

If the inverter overload capacity is exceeded under normal mode, or if the inverter becomes unavailable for any reason, the static transfer switch will perform a transfer of the load from the inverter to the bypass source, with no interruption in power to the critical AC load. Should the inverter be asynchronous with the bypass, the static switch will perform a transfer of the load from the inverter to the bypass with power interruption to the load. This is to avoid large cross currents due to the paralleling of unsynchronized AC sources. This interruption is programmable but typically set to be less than 3/4 of an electrical cycle, e.g., less than 15ms (50Hz) or less than 12.5ms (60Hz).

5.3.5 Maintenance Mode (Manual Bypass)

A manual bypass switch is available to ensure continuity of supply to the critical load when the UPS becomes unavailable e.g. during a maintenance procedure.

5.3.6 Parallel Redundancy Mode (System Expansion)

For higher capacity or higher reliability or both, the outputs of several UPS modules can be programmed for direct parallel while a built-in parallel controller in each UPS ensures automatic load sharing.

5.3.7 Eco Mode

To improve system efficiency, UPS rack system works in bypass mode at normal time, and inverter is standby. When utility fails, UPS transfer to battery mode, and inverter power the loads. The efficiency of ECO system can be up to 98%. NOTE: There is a short interruption time (lower than 10ms) when transfer from ECO mode to battery mode, it must be sure that the time has no effect on loads.
