DANGER The EPS works with dangerous voltages. Only SKILLED TECHNICIANS must perform the installation and ordinary maintenance operations. No part of the EPS can be repaired by the operator.

Extraordinary maintenance operations must be carried out by LEGRAND Technical Support Service personnel.

WARNING

A battery can present a risk of electrical shock and high short circuit current. The following precautions should be observed when working on batteries: a) remove watches, rings or other metal objects; b) use tools with insulated handles; c) wear rubber gloves and boots; d) do not lay tools or metal parts on top of batteries; e) disconnect the charging source prior to connecting or disconnecting battery terminals; f ) determine if battery is inadvertently grounded. If inadvertently grounded, remove source from ground. Contact with

any part of a grounded battery can result in electrical shock. The likelihood of such shock can be reduced if the ground connections are removed during installation and maintenance (applicable to remote equipment and battery supplies without a grounded supply circuit).

g) never leave powered cables uncovered.

Do not dispose of batteries in a fire. The batteries may explode. Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. The batteries installed inside the cabinet must be disposed of correctly. For the disposal requirements refer to local laws and relevant standards.

CAUTION The EPS works with TT and TN systems. It has a pass-through neutral architecture: the status of the output neutral is

the same as the input neutral. When the output load needs a different neutral status from the input status, it is necessary to place downstream of the EPS a suitably scaled isolation transformer protected in compliance with the standards in force.

CAUTION

Do not open the battery fuse holders while the EPS is powering the loads in battery mode.

WARNING

To reduce the risk of fire or electric shock, the EPS must work in clean and indoor environments with controlled temperature and humidity. It must be kept away from inflammable liquids and corrosive substances. The room temperature must not be above +40°C (+104°F) and the relative humidity must be a maximum of 95% not condensing.

3. Technological description

3.1 Trimod MCS technology

LEGRAND® has developed an innovative project that is the only one of its kind by producing Trimod MCS, the EPS with 3, 5, 7, 10, 15, 20, 30, 40, 60 and 80 kVA power. The concepts underlying the project are modularity, expandability and redundancy in such a way as to offer maximum reliability and to be the guarantee of considerable savings.

Trimod MCS is EPS designed in accordance with EN 50171 for the preservation of power supply in emergency and security systems. Some of its features are:

- permanent overload capability of 120% in relation to the rated power;

- batteries with rated life expectancy of 10 years;

- battery polarity inversion protection

- protection against complete discharge;

- short circuit protection;

- high current battery charger for full charge time of 12 hours;

- IP20 metal enclosure according to EN 60598-1. If the mains is available, the EPS output is enabled by default. It is possible to change this setting from the control panel. If the mains input is missing, the output is supplied by the EPS in battery mode.

Trimod MCS is a modular EPS whose base module is single phase and can be programmed to obtain the desired input/ output configuration. It is thus possible to manage three phase and single phase voltages on input and output to have a choice of the traditional three phase/three phase, three phase/single phase, single phase/three phase and single phase/ single phase. At the same time it is possible to obtain simultaneously single phase and three phase lines on output or two or more single phase lines even with different power.

For every configuration it is possible to have redundancy that is both complete and partial. For example, one normal three phase (or redundant) line can coexist with a redundant single phase (or normal) line on output. The philosophy underlying modularity has also been applied to the batteries that have been supplied in individual drawers that can be extracted and make installation and maintenance easier.

The EPS is controlled by one command board.

The command board (CM) and the power modules (PM) are identified by a unique address inside the system, as shown below:

3. Technological description

The command board is connected to a control panel with display from which it is possible to verify the status and setups of the EPS and to a communication interface with RS-232 and SNMP connection, dry contacts and logical contacts. It is possible to access all the EPS functions from the control panel and communicate through any of the interfaces present thereby guaranteeing the redundancy of the peripherals as well. In installations with three separate single phase line on output, it is possible to manage each line independently through the software. For example, it is possible to prioritise the autonomy of one of them during battery operation. A bypass input line separated from that of the mains input makes it possible to supply the bypass with a second power source (the neutral wires of the two lines must be in common).

The technology used in the hardware and the firmware of the EPS represents the current state of the art. A sophisticated microprocessor-type control optimises the performance both on the Booster/PFC side and on the output inverter. The recharge curve of the battery has been designed to get the maximum useful life and have the greatest autonomy possible if the main power goes off. The electronic boards are entirely assembled on LEGRAND automated lines and tested to the highest quality standards. Every device goes through an extended period of operation at full load before being sent to the customer.

3.2 Features

Modular-redundant architecture

The modular-redundant architecture is the best solution for protecting the nerve centres of a company and has the following advantages:

- there is one control of the devices supplied;

- modular expandability;

- module redundancy;

- easy maintenance;

- low running cost;

- compactness.

Efficiency

Trimod MCS concentrates particularly on both the energy absorbed from the mains and the energy provided to the load. They are characterised by high efficiency (up to 96%), PF on input>0,99, THDi <3%. The advantages of a high efficiency are:

- reduction of the power absorbed from the EPS but not supplied to the load and transmitted to the environment as heat;

- less heat loss transmitted to the environment means reducing the need for ventilation or air conditioning systems in the

installation site;

- no power factor correction cost and so no increase in charges;

- no need to increase the size of any generator upstream of the EPS.

Expandability

Most EPS systems on the market are of the non-modular and non-expandable type thus requiring an initial upscaling of the system to make future expansions possible. The advantages of an expandable system are:

- optimisation of investments for EPS, making them adequate for the current requirements without precluding future

expansions and avoiding wastes of energy;

- increase in the efficiency of the system thanks to proper sizing.

Reliability

To obtain a level of redundancy with traditional EPS, it is necessary to put at least two in parallel thereby doubling the power acquired, the space occupied and the electricity consumed. Trimod MCS modular architecture makes it possible to have redundant configurations within a single cabinet. The advantages are:

- a redundant modularity EPS can be configured as a power redundant N+X system. Even in the case of a fault in a

module, the equipment continues to function avoiding any downtime;

- clear indications and a large display make it possible to find the fault more quickly;

- the modular architecture makes it possible to speed up the solution to problems through the simple replacement of the

faulty module without interrupting the service;

- high percentage of faults resolved at the first attempt.

Power module

The high-efficiency single phase module, available in three power sizes of 3400 VA (PM4), 5000 VA (PM6) and 6700 VA (PM7) respectively, and is mainly made up of the following functional blocks:

- command and control logic (managed by a microprocessor);

- PFC rectifier/booster;

- inverter;

- battery charger;

- automatic bypass. In each power module there is a microcontroller that can oversee the main functions of the individual unit, monitor its correct operation and flag up any malfunctions.

The power module is Plug & Play to make the power expansion and any maintenance operation easier. Every module is put in parallel with other identical ones until reaching the power of the EPS. The modules are independent of each other and can function even if there is a fault in one of them. At the front of the module there is a multicoloured LED with traffic-light code green-yellow-red, making it possible to identify the operating status of the electronic unit quickly.

The power modules are housed on shelves also called “tunnels” that can house three modules.

The block diagram of the power module is the following:

Trimod MCS

User manual

Batteries

The battery modules are designed for easy insertion into the dedicated cabinet and they do not need any operation for their connection. A drawer consists of five 12V-9Ah batteries, connected in series and thanks to the Plug & Play connection it is easy to extract and insert it in the cabinet. The nominal battery voltage for the Trimod MCS is 240Vdc, therefore a complete branch consists of four battery drawers (for a total of twenty 12Vdc batteries) that form what is called KB (Battery Kit). In order to ensure the maximum level of safety, the voltage of each drawer is properly isolated into two branches of 24 V and 36 V and it is only restored when the drawer is completely inserted into its housing. This allows conformity with the standard EN 62040-1 on electrical safety that requires the use of adequate protection and particular care when handling dangerous voltages above 50 Vdc where direct contact is possible. The battery operation autonomy of the EPS can be increased by adding more battery drawers in multiples of four, using both the seats in the EPS cabinet if available, and the seats in the additional modular battery cabinets.

Digital display and alarm display

Trimod MCS is managed by a microprocessor-type command board (according to the version) and it has a backlit LCD alphanumeric display with twenty characters on four lines. The display is incorporated in the control panel where there is also a high-brightness operating status indicator with traffic light type green-yellow-red. Five keys situated near the display enable the user to display the operating data, set the operating parameters, analyse the status of the individual power modules, select the language in which the messages are to be displayed and carry out a guided set of functional tests and procedures.

BCM - Battery Charger Module 3 108 51

The additional battery charger module works in parallel and in sync with the battery chargers in the power modules and it is managed by the same algorithm that governs the recharging cycle. Every additional battery charger module provides up to 15A of charge current that are added to the current of the battery chargers inside the power modules. Every power module can provide up to 2.5A of charge current. This guarantees a reduction of the charge time in installations requiring long autonomies and increases the availability of the UPS after a black out. During operation, the module takes current from the input phase where it is installed. It is possible to install any quantity of BCMs as long as there is at least one power module and enough empty slots inside the EPS cabinet. All the information regarding the operating status of the BCM is given by the LED on the front of the module and by what is shown on the EPS display. The module is managed by a microprocessor to optimize performance and reliability. It is recommended to install it together with a battery cabinet with capacity exceeding 60 Ah.

ECO MODE

One functioning mode of Trimod MCS is called “eco mode”. With this mode it is possible to save energy while guaranteeing uninterruptability of the power supply to the load connected. During the functioning in eco mode, the load is powered directly from the electrical mains through the automatic bypass circuit inside the power modules. This means that the output voltage and frequency are the same as the mains. The advantage obtained in the eco mode is a greater electrical efficiency and consequently a reduction in consumption. If the output voltage leaves the window of tolerance (-20% / +15% of the voltage set on the output), the EPS actuates its inverter stage and powers the load with the energy stored in the batteries. The autonomy during the battery operation depends on the configuration of the UPS (nominal power, battery capacity) and on the percentage of load applied. When the mains are back within the tolerance values, the EPS switches automatically back to the eco mode. It is possible to change the operating mode

between on-line and eco mode (and viceversa) both with the EPS on and with the UPS off (in this case entering the Service Mode).

5. Communication devices

Trimod MCS EPS have two RS232 serial ports, one contact interface, one logic level interface on DB15 socket and one SNMP slot. The communication interfaces are found in the rear of the equipment. The RS232 serial maintenance port is inside the EPS door, above the first row of power modules.

CAUTION

For the operator's safety it is essential the interfaces are connected in such a way that:

- the maximum voltage between any two wires connected to the interface and between any one of these wires and the earth is less than 42Vpk or less than 60Vdc;

- the insulation voltage between any wire connected to the interface and the earth is at least 1500Vac.

5.1 RS232 serial ports

The first of the two RS232 serial ports is called “maintenance RS232” and is found above the first row of power modules, in a part accessible only to a skilled technician with a key to open the door. The RS232 maintenance door is dedicated exclusively to diagnostic functions and to update the equipment firmware.

User manual

The second serial port called “user interface” is located at the back of the EPS. Via computer, this port allows to access some data relative to the operation of the device as well as control the unmanned shutting down of the operating system.

If enabled, the EPS synchronises the output pure sine with that of the input. If disabled, the output voltage is not synchronised with the input and it is indicated with the status light (green) flashing.

This makes it possible to set the output frequency value (50 Hz or 60 Hz) independently of the input frequency.

If enabled, the EPS detects the frequency of the input voltage and synchronises the output to the same value. If disabled, the EPS uses the "Nominal Value” setting.

This makes it possible to program the start-up status for each output:

- Always ON: phase always on during start-up

- Always OFF: phase always off during start-up

- Last state: phase restored to the status prior to the shutdown

This makes it possible to select the frequency range in which the EPS synchronises the output voltage with the input:

INDICATION

The PLL function ensures that the output frequency is synchronised with that of the input, guaranteeing that passage through zero (zero-crossing) occurs at the same moment. The input-output synchronisation is guaranteed even in case of bypass intervention (e.g. because of overload).

INDICATION

By disabling the PLL function, the automatic bypass function is deactivated as well. The equipment turns off in case of an extended overload.

- EXTENDED: syncronization for frequency variations of ±14% of the nominal value

- CUSTOM: this can be set by the user (see the next menu item)

This makes it possible to set the customised frequency interval in which the EPS synchronises the output voltage with the input. The value can be selected from a minimum of 0.5 Hz to a maximum of

7.0 Hz with 0.1 Hz step

Bypass

If enabled, the EPS manages the bypass intervention automatically.

Bypass enable

Forced Mode If enabled, the EPS activates the bypass permanently

DIP speed

O-Line Mode

Startup on Bypass

If disabled, the EPS never switches to bypass mode so in the case of an extended overload or in the case of failure and absence of redundancy, it turns off.

It allows to vary the switching circuit sensitivity:

- SLOW: indicated for loads that are not sensitive to voltage fluctuations

and that cause current peaks

- STANDARD: normal mode

- FAST: for all loads that are highly sensitive to voltage fluctuations

If enabled, the EPS operates in eco mode. During the operation, the load is powered directly by the automatic bypass circuit. If there is a power failure or the voltage input tolerance is exceeded, the EPS activates the inverter thereby powering the load through the batteries.

If enabled, on mains start-up the initial powering of the load occurs via bypass. If disabled, the inrush current is managed by the inverter as in a battery start-up.

8. Installation and maintenance

DANGER INSTALLATION and ORDINARY MAINTENANCE operations must be carried out only by SKILLED TECHNICIANS (paragraph 2.2.1). The EXTRAORDINARY MAINTENANCE operations must be carried out only by the LEGRAND TECHNICAL SUPPORT SERVICE.

8.1 Introduction

This chapter contains all the information necessary for an operator to correctly install and maintain the EPS.

DANGER

The operator is not authorised to perform the operations contained in the installation and maintenance manual. LEGRAND declines all liability for any injury or damage caused by activities carried out differently from the instructions in this manual or by a skilled technician who does not observe the requirements laid down in the installation and maintenance manual.

8.2. Installation

The operator is not authorized to install and electrically connect the EPS. These operations are the sole preserve of a skilled technician (paragraph 2.2.1) who must follow the instructions addressed to him in the installation and maintenance manual.

8.3 Preventive maintenance

The EPS does not contain parts for preventative maintenance by the operator. The operator must periodically perform:

- a normal general external cleaning;

- a check to verify the absence of alarms on the display;

- a check to verify the correct operation of the fans on each power module.

After the first year of EPS life, check the batteries every six months through the "battery calibration" function to guarantee the optimal operation and continuous protection of the connected load. With this function, the EPS detects the discharge curve of the batteries in order to provide precise information on the charging status. To activate the function enter the main menu and follow the path Tools  Batteries  Batt. Calibration Press the ENTER key to confirm the choice.

Contact the LEGRAND Technical Support Service in case of problems.

8.4 Periodical checks

The correct EPS operation must be guaranteed by periodical maintenance inspections. These are essential to safeguard the EPS reliability.

DANGER

The periodical checks involve operations inside the EPS in presence of dangerous voltages. Only maintenance personnel trained by LEGRAND are authorized to work.

8.5 Ordinary maintenance

Contact a skilled technician if it is necessary to replace or add power modules, battery drawers for modular Trimod MCS BATTERY or batteries for non-modular Trimod BATTERY.

8.6 Extraordinary maintenance

Contact the LEGRAND Technical Support Service if faults have occurred which require access to internal parts of the EPS.
