DEFINITION OF THE PRODUCT

Nomenclature.
SLC-3000-TWIN RT2 LION WCO EE29503

OPERATING PRINCIPLE

This manual describes the installation and operation of the SLC TWIN RT2 LION series of Uninterruptible Power Supplies (UPS). SLC TWIN RT2 LION series UPSs ensure optimum protection of any critical load, maintaining the supply voltage of the loads between the specified parameters without interruption during failure, deterioration or fluctuation of mains power.
Thanks to their PWM (pulse width modulation) and double-conversion technology, SLC TWIN RT2 LION series UPSs are compact, cool, silent and high performance.
The double converter principle eliminates all mains power dis-turbances. A rectifier converts the AC current of the mains into DC current, thereby maintaining optimum battery charge level and powering the inverter, which, in turn, generates a suitable AC sine-wave voltage for continuously powering the loads. In the event that the UPS’s input power supply fails, the Li-ion batteries will supply clean power to the inverter.
The design and construction of the SLC TWIN RT2 LION se-ries UPS has been carried out in accordance with international standards.
Consequently, this series has been designed to maximise the availability of critical loads and to ensure that your business is protected against any variations in voltage, frequency, electrical noise, cuts or dropouts that may occur in the power supply. This is the primary goal of SLC TWIN RT2 LION series UPSs.
This manual applies to the standardised models shown in Tab. 1.
Characteristics and main advantages of Li-ion batteries. Like lead-acid batteries, lithium-ion (Li-ion) batteries consist of four components: anode, cathode, electrolyte and separator.
Two compounds act as electrodes and are immersed in the electrolyte. The same material, lithium carbonate, is used for the anode in all Li-ion batteries. The material used for the cathode can vary. Li-ion batteries use lithium oxide (Li2O).
Main advantages:

• Increased energy density: The accumulator’s energy density determines the battery’s capacity. The energy density of Li-ion batteries is approximately three times higher than that of lead-acid; thus, when comparing Li-ion and lead-acid batteries of similar size, the capacity of the former would be three times higher.

• Increased energy efficiency and higher voltage: Lithium is a highly electronegative chemical element. Its increased oxidation capacity means the voltage of Li-ion batteries is higher. While a lead-acid battery cell produces 2 V, a Li-ion cell produces in excess of 3.6 V.
  Overall performance levels, meanwhile, reach 98%.

• Improved energy profile: The energy profile measures the charge status in relation to charge time and battery use. Li-ion batteries boast a superior energy profile.
  Because they operate at a higher voltage, a less intense current is needed to produce the same amount of energy, meaning the battery needs less time to charge.

• Depth of discharge: While the useful life of lead-acid accumulators can be maximized if they are kept at just 20%discharge, and it is not recommended to let them discharge by more than 50%, Li-ion batteries do not suffer from this problem and can be discharged up to 100%.

• Longer useful life: Following on from the previous point, it should be noted that the useful life of a deep-cycle lead-acid Monoblock is 600-700 charge-discharge cycles. In contrast, the useful life of a Li-ion battery is around 10 times longer, i.e. 6,000+ cycles.

• Maintenance-free: Li-ion batteries are sealed and do not require any form of maintenance.

UPS OPERATING MODES.

• Normal mode.
  Device running supplying output voltage from the inverter. Mains power present with correct input voltage and fre-quency.

• Battery mode.
  Device running with mains voltage or frequency out of range or without AC input power, either due to mains failure or absence of cable connection, supplying output voltage from the batteries.

• Bypass mode.
  Device running or not, supplying output voltage directly from the AC mains.
  With the inverter running, this operating mode may be due to an overload, blockage or inverter fault.
  The actions for each incident will be as follows: Reduce the load connected to the output, unblock the device by reset-ting it – stop it and start it up again – and, if the blockage or fault remains, contact our T.S.S.
  With the inverter shut down, the output supplies mains power directly through the static bypass of the device pro-vided that it has AC input power.

• Frequency converter (CF) mode.
  Operating mode of the UPS as a frequency converter. In this mode, the static bypass is disabled by the condition of dis-parate input and output frequencies.

Even if the LCD on the backlit control panel shows mes-sages, it does not mean that the inverter is operational. It is switched on by pressing the ‘ON’ button on the control panel, see Chapter 6.

Notable features.

• True on-line with double-conversion technology and output frequency separate from the mains.
• Output power factor 0.9. Pure sine-wave waveform, suit-able for all types of load.
• Input power factor > 0.99 and high overall performance (be-tween 89% and 91%). Greater energy savings and lower user installation costs (wiring), as well as low distortion of the input current, which reduces pollution in the power supply network.
• Great adaptability to the worst conditions of the mains. Wide input voltage, frequency and waveform ranges, thus avoiding excessive dependence on limited battery power.
• Battery recharge time < 3h.
• Selectable high-efficiency mode (ECO MODE) > 95%. En-ergy savings, economically beneficial to the user.
• Possibility of starting the device without mains power supply or discharged battery. Pay attention to this last as-pect because the more the batteries are discharged, the more the backup will be reduced.
• Intelligent battery management technology is very useful for extending the life of accumulators and optimising re-charge times.
• Standard communication options via the RS-232 serial port or USB port.
• Remote emergency power off control (EPO).
• Control panel with LCD display.
• Availability of optional connectability cards to improve communication capabilities.
• The device can be configured as a tower or rack using the accessories supplied. The control panel can be rotated to adapt to either format.

OPTIONAL EXTRAS.

Depending on the configuration chosen, the device can include any of the following options:

Isolation transformer.
The isolation transformer provides galvanic isolation in order to completely isolate the output from the input and/or change neutral point treatment.
The placement of an electrostatic screen between the primary and secondary windings of the transformer provides a high level of electrical noise attenuation.
The isolation transformer can be physically placed at the input or output of the UPS depending on the technical conditions of the whole system (device supply voltage and/or load voltage, characteristics or their type, etc.).
It will always be supplied as a peripheral component external to the device itself in a separate enclosure.

Exterior manual maintenance bypass.
The purpose of this option is to electrically isolate the device from the mains and the critical loads without cutting the power to the latter. In this way, maintenance or repair operations on the device can be carried out without interruptions to the power supply of the protected system, while preventing unnecessary hazards for technical personnel.

Communication card.
The UPS features a slot at the rear for inserting one of the fol-lowing communication cards.

Integration into computer networks using an SNMP adapter.
Large computer systems based on LANs and WANs that integrate servers in different operating systems must provide the system manager with ease of control and administration. This facility is obtained through an SNMP adapter, which is universally sup-ported by the main software and hardware manufacturers.
Connection of the UPS to the SNMP is internal while that of the SNMP to the computer network is made through an RJ-45 10 base connector.

RS-485 modbus.
Large computer systems based on LANs and WANs often re-quire that communication with any element that is integrated into the computer network be made through a standard indus-trial protocol.
One of the most used standard industrial protocols on the market is the MODBUS protocol.

Relay interface.
The UPS has, as an option, a relay interface card that provides digital signals in the form of potential-free contacts, with a maximum applicable voltage and current of 240 V AC or 30 V DC and 1 A.
This communication port enables dialogue between the device and other machines or devices through the relays supplied in the terminal block arranged on the same card, with a single common terminal for all of them.
From the factory, all contacts are normally open and can be changed one by one, as indicated in the information supplied with the optional extra.
The most common use of these types of ports is to provide the necessary information to the file-closing software.
For more information, contact our T.S.S. or our nearest dis-tributor.

Extendable guide kits for mounting in a rack cabinet.
An extendable and unique guide kit is available for all device models, valid for any kind of rack-type cabinet.
These guides enable any TWIN RT2 LION unit to be installed like a rack in its respective cabinet.

INSTALLATION

Read and respect the Safety Information, described in Chapter 2 of this document. Failure to obey some of the instructions described in this manual can result in a serious or very serious accident to persons in direct contact or in the vi-cinity, as well as failures in the device and/or loads connected to it.
In addition to the device’s own user manual, a number of other documents are supplied along with the Quick Start guide. Con-sult them and strictly follow the indicated procedure.

RECEPTION OF THE DEVICE.

Pay attention to section 1.2.1. of the safety instructions -EK266*08- in all matters relating to the handling, movement and siting of the unit.
Use the most suitable means to move the UPS while it is packed, with a pallet jack or forklift.
Any handling of the device must be carried out in accordance with the weights shown in the technical specifications ac-cording to the model, indicated in Chapter 9. Annexes.

Reception, unpacking and contents.

• Reception. Check that:

  • The data on the label affixed to the packaging corre-sponds to that specified on the order. Once the UPS is unpacked, check the previous data with those of the device nameplate.
    If there are discrepancies, report the issue as soon as possible, citing the device’s manufacturing number and delivery note references.

  • It has not suffered any mishaps during transportation (packaging in perfect condition).
    If this is not the case, contact your distributor.

  • 2 metal pieces for use as handles and screws for in-stalling the unit in a rack cabinet.
  • 4 plastic pieces for use as a base and screws to facilitate the arrangement of the UPS as a tower (vertical position).

Once the reception is completed, it is advisable to re-pack the UPS until it is put into service in order to protect it against me-chanical shock, dust, dirt, etc. The device’s packaging consists of a cardboard box, expanded polystyrene corners and polyethylene cover and strapping, all of which can be recycled. When the packaging requires dis-posal, it must be carried out in accordance with current laws.
We recommend keeping the packaging for at least 1 year.

Storage.
The device should be stored in a dry, ventilated location protected from rain, dust, water splashes and chemical agents. It is advisable to keep each device and battery unit in its original packaging, as it has been specifically designed to ensure max-imum protection during transportation and storage.
For devices that contain Li-ion batteries, the charging frequency and charge duration indicated in the table below (which are based on the device’s storage temperature) must be observed, otherwise the warranty may be invalidated.

Storage temperature| Charging frequency| Charge duration
---|---|---
35ºC ~ 45ºC| Every month| 1 h @ 5ºC ~ 35ºC
25ºC ~ 35ºC| Every 1-3 months| 1 h @ 5ºC ~ 25ºC
-10ºC ~ 25ºC| Every 3-12 months| 1 h @ 5ºC ~ 25ºC

Tab. 2. Frequency and duration of Li-ion battery charging  based on storage temperature.
Then shut down the device, disconnect it and store the UPS and batteries in their original packaging, noting the new date for recharging the batteries on a document as a record or even on the packaging itself.
Do not store the devices where the ambient temperature ex-ceeds 50°C or drops below -15°C, as this may cause degradation of the electrical characteristics of the batteries.

Unpacking.
The packaging of the device consists of a cardboard box, ex-panded polystyrene (EPS) or polyethylene foam (EPE) corners, polyethylene cover and strapping, all of which are recyclable materials; consequently, if it requires disposal, it must be carried out in accordance with current laws. We recommend keeping the packaging in case it needs to be used in the future.
Proceed as follows:

• Cut the straps around the cardboard box.
• Remove the accessories (cables, brackets, etc.)
• Remove the device from the packaging, using another person to help or suitable mechanical means where necessary, depending on the weight of the model.
• Remove the protective corners from the device and the plastic bag.
• Do not leave the plastic bag within the reach of children to avoid danger of suffocation.
• Inspect the device before proceeding and, in the event of finding damage, contact the supplier or, failing that, our firm.

Transport to the site.
It is recommended to transport the UPS by means of a pallet jack or the most appropriate method considering the distance between the two points.
If the distance is considerable, it is recommended to transport the device in its packaging to the installation site and then un-pack it.

Siting, immobilising and considerations.
All TWIN RT2 LION UPSs are designed to be mounted as a tower model (i.e. placed vertically) or rack model (i.e. placed horizontally) for installation in 19” cabinets.
Follow the instructions indicated in the sections relating to ei-ther of the two possibilities, according to the particular configu-ration of your device.
Fig. 3 to Fig. 5 provide illustrations of the device’s design.
These illustrations provide help and guidance on the steps to follow, but the instructions are not intended to refer to a single model, although, in practice, the actions to be carried out are always the same for all of them.
For all instructions regarding connections, refer to section 5.2.

Rotation of the control panel with LCD.

To facilitate the reading of messages on the display when the device is installed vertically, it is possible to rotate the control panel clockwise by 90º (see Fig. 3).
Likewise, reverse the rotation of the control panel if a device arranged as a tower needs to be installed as a rack.
In this case, the rotation of the control panel will be anti-clock-wise.
Proceed as follows:

• Insert fingertips into the recesses of the plastic trim around the display and pull outwards.
• Rotate the control panel with LCD 90º to the right with re-spect to its initial position and insert it back into the front.

Vertical tower-type mounting.

• Rotate the control panel according to section 5.1.5.1.
• Take the 4 plastic pieces supplied with the equipment, two by two, fit them together and secure them with the sup-plied screws to obtain two pedestals or bases.
• Place the UPS upright between the two bases at a distance of 70 mm from each end (see Fig. 4).

Mounting as a rack in a 19” cabinet.
To mount a device in a 19” rack cabinet, proceed as follows (see Fig. 5):

• Using the supplied screws, fix the two adapter angles for use as handles on each side of the UPS, respecting your hand.
• To install the device in a rack cabinet, it is necessary to have internal lateral guides for use as supports. Alterna-tively, and upon request, we can supply universal slides for use as guides, for installation by the user.
• Mount the guides at the required height, ensuring correct tightening of the fixing screws and appropriate fitting in the machining, according to each case.
• Place the device onto the guides and insert it all the way to the back.
• Depending on the device model and weight, and/or whether it is installed in the upper or lower part of the cabinet, it is recommended that two people carry out the installation operations.
• Fix the UPS to the cabinet frame using the screws supplied with the handles.

Preliminary considerations before connection.
Thermal control of these devices is carried out with the pas-sage of forced air from the front to the rear.
The front surface and about 15 cm on the rear side should be left free of obstructions to facilitate the free circulation of air for ventilation.
Follow and observe the instructions provided in this section.
Protection or external manual bypass board:

• The system will have at least one short-circuit protection on the UPS’s power supply line.
• It is advisable to have an external manual bypass board fitted with input, output and manual bypass protections.

Upon request, we can supply an external manual bypass board.
You can also choose to manufacture one, taking into account the version and configuration of the available device or system and the attached documentation regarding ‘Recommended in-stallation’.
Only rated currents are printed on the nameplate of the device as indicated by the EN-IEC 62040-1 safety standard. For the cal-culation of the input current, the power factor and the device’s own performance have been considered.
Overload conditions are considered a non-permanent and ex-ceptional working mode, and will not be taken into account in the application of the protections. Do not connect appliances or devices which may overload the UPS to the terminals and/or outlets, such as motors.
If peripheral input or output elements, such as transformers or autotransformers, are added to the UPS, the currents indi-cated on the nameplates of these elements must be taken into consideration when determining appropriate cross sections, in compliance with local and/or national low voltage electrotech-nical regulations.
When a galvanic isolation transformer is added to a UPS as standard, as an optional extra or independently, either on the input line, at the output or both, it must be fitted with protec-tion against indirect contact (differential circuit breaker) at the output of each transformer, since, due to its own insulation properties, it will prevent the tripping of the protections placed on the primary of the isolation transformer in case of electric shock on the secondary (output of the isolation transformer).
We remind you that all the isolation transformers installed or factory supplied, have the output neutral earthed through a jumper between the neutral terminal and earth. If the iso-lated output neutral is required, this jumper must be removed, taking the precautions indicated in the respective local and/or national low voltage regulations.

This device is suitable for installation in networks with TT, TN-S, TN-C or IT power distribution systems, taking into account at the time of installation the particularities of the system used and the national electrical regulations of the destination country. The SLC TWIN RT2 LION features terminals for the installation of an external emergency power off button (EPO) or, failing that, a single device must be installed to cut the power supply to the loads in any operating mode.

Preliminary considerations before connection, regarding the batteries and their protections.
The batteries for the SLC TWIN RT2 LION models are in the same box as the devices.

VERY IMPORTANT: For safety reasons, the batteries are disconnected. Before installing the UPS, follow the steps below to reconnect them:

The batteries are always protected by internal fuses that are not accessible to the user.

If the mains power of the device or parallel system is cut for longer than a simple intervention and it is expected that it will be out of service for a prolonged period time, the system must be shut down completely.

Connection elements.
All of the device’s electrical connections are made from the back of each unit:

• Input and output connection.
  • Input by means of a cable with plug, connectable to the UPS through an IEC connector.
  • Outputs through IEC connectors.
• Communication connectors available:
  • DB9 for RS-232.
  • USB to operate the UPS as a PC peripheral.
  • For connection to external EPO button.
  • Slot for the integration of one of the optional electronic communication units. Remove the fixing screws and plastic cover to enable it to be inserted.

CONNECTIONS

Connection of the input.

• Take the power cable with plug and IEC connector on the end and insert the latter into the input connector of the UPS.
• Plug the power cable into an earthed AC power socket.

Connection to the IEC output connectors.
The SLC TWIN RT2 LION models have a different number of female IEC output connectors, depending on the power of the model:

•  models up to 2 kVA: Two groups of four IEC 10A connectors identified as ‘OUTPUT’ and ‘OUTPUT PROGRAMMABLE (P1)’, which can be configured via the control panel and/or ViewPower.
• 3 kVA models: same connectors as models up to 2 kVA and an additional 16A IEC connector.

Do not connect loads that in their entirety exceed the specifications of the device, as this would cause incon-venient cuts in the power supply of the loads connected to the output.
If, in addition to the more sensitive ‘critical loads,’ it is neces-sary to connect high-consumption inductive loads, such as for laser printers or CRT monitors, the starting up of these periph-erals will need to be taken into account to prevent the device from crashing.
We do not recommend connecting loads of this type due to the amount of power they absorb from the UPS.

Connecting the loads.
Connect the loads to the 10 A IEC connectors. It is important to consider the two groups of IEC connectors available, those for ‘critical loads’ and those for ‘non-critical loads’.
By definition, ‘critical loads’ are considered to be those that can cause economic damage if they stop functioning or function incorrectly.
The IEC connectors indicated in Fig. 2 as ‘non-critical loads’ can be programmed as such through the control panel. In this case, the backup of the batteries for the loads connected to the IEC connectors indicated in Fig. 2 as ‘critical loads’ will be reserved. Take into account that they are set by default as ‘critical loads’.
The 3 kVA models also have a 16A IEC connector that enables the connection of a load of the total power of the device.

Terminals for EPO (emergency power off).
The UPSs have two terminals for the installation of an external emergency power off (EPO) output button.
The device is dispatched from the factory with its EPO circuit set to closed (NC) by default. In other words, the UPS will cut the output power supply, emergency power off, when the cir-cuit is opened:

• Either by removing the female connector from the socket where it is inserted. This connector has a cable connected as a jumper that closes the circuit (see Fig. 6- A),
• or by pressing the button external to the device belonging to the user installed between the terminals of the connector (see Fig. 6- B). The connection on the button must be in the normally closed contact (NC), so it will open the circuit when activated.

The reverse functionality can be selected via the communica-tions software and control panel (settings menu 15).
Except for specific cases, we advise against this type of con-nection in view of the purpose of the EPO button, since it will not act upon an emergency request if either of the two cables that run from the button to the UPS is accidentally cut.
By contrast, this anomaly would immediately be detected in a closed EPO circuit, with the inconvenience of an unexpected cut in the powering of the loads, but a guarantee of effective emergency functionality.
To recover the normal operating state of the UPS, it is necessary to insert the connector with the jumper in its receptacle or deactivate the EPO button. The device will be operational.

Communication port.
The COM communications line is a very low voltage safety circuit. To preserve the quality, it must be in-stalled separately from other lines carrying dangerous voltages (power distribution line).
The RS-232 and USB interfaces are useful for the monitoring software and updating the firmware.
It is not possible to use both the RS-232 and USB ports at the same time.
In connector DB9, the signals of the RS-232 are supplied.
The RS-232 port consists of the transmission of serial data in such a way that a large amount of information can be sent through a communication cable with only 3 wires.
The USB port is compatible with the USB 1.1 protocol for communication software.Smart slot for the integration of an electronic communication unit.
Optional electronic communication units include:

• Relay interface to terminals, not programmable.
• SNMP adapter.
• RS-485 modbus adapter.

The corresponding documentation is supplied with each option. Read it before starting installation.
Installation.

• Remove the protective cover from the device’s slot.
• Take the corresponding electronic unit and insert it into the reserved slot. Make sure that it is properly connected, for which it is necessary to overcome the resistance caused in the connector located in the slot.
• Make the necessary connections in the terminal block or connectors available according to each case.
• Fit the new protective cover supplied with the relay inter-face card and secure it with the screws from the old cover.
• For more information, contact our T.S.S. or our nearest dis-tributor.

Protection against voltage spikes for the modem / ADSL / fax, etc., line. .
The COM communications line is a very low voltage safety circuit. To preserve the quality, it must be in-stalled separately from other lines carrying dangerous voltages (power distribution line).

• Connect the main line for the modem / ADSL / fax, etc., to the RJ45 connector of the device, identified as ‘Input.’
• Connect the modem / ADSL / fax, etc., to the RJ45 connector of the device, identified as ‘Output.’

Download of free ViewPower software.
ViewPower is a UPS monitoring software which provides a user-friendly interface for monitoring and control. It features an auto shutdown function for systems consisting of several PCs in case of power failure. The software enables users to monitor and control any UPS in the same LAN through an RS-232 or USB communications port, regardless of how far away they are from each other.

Installation procedure:

• Go to the web page: http://support.salicru.com
• Select the required operating system and follow the instructions described on the web page to download the software.

Considerations before startup with connected loads.
We recommend charging Li-ion batteries for at least five hours before using the UPS for the first time.
For this, it will be necessary to supply voltage to the device. The battery charger will work automatically.
Although the device can operate correctly without charging the batteries for the specified 5 hours, the risk of a prolonged power cut during the first hours of operation and the UPS’s available backup time should be assessed.
Do not start up the device and loads completely until indicated in Chapter 6.
When it is done, however, it should be carried out gradually to avoid possible difficulties, if not at the first startup.
If, in addition to the more sensitive loads, it is necessary to connect high- consumption inductive loads, such as for laser printers or CRT monitors, the starting up of these peripherals will need to be taken into account to prevent the device from crashing.
For this type of load considered NON-PRIORITY, a group of programmable terminals is available depending on the model. De-pending on the programming of these, the power supply may or may not be affected in the event of mains failure.

OPERATION

START-UP.

Checks before start-up.

• Make sure that all of the connections have been made cor-rectly, following the instructions on the labelling of the de-vice and in Chapter 5.
• Check to make sure the UPS switch is in the ‘Off’ position.
• Make sure that all loads are ‘Off’.

Shut down the connected loads before starting the UPS and start the loads, one by one, only when the UPS is running. Before shutting down the UPS, check that all of the loads are ‘Off’.

1. It is very important to proceed in the established order.
2. For views of the UPS, see Fig. 1 and Fig. 2.

UPS STARTUP AND SHUTDOWN.

UPS startup with mains voltage.

• Check that the power connection is correct.
• Supply voltage to the device (set the input protection of the distribution board or manual bypass to ‘On’). If the board has an output switch, set it to ‘On’).

The IEC output connectors will have voltage through the device’s internal static bypass block.
The fan or fans, depending on the model, will start to func-tion.
Then the main start screen will be displayed after a test of the device.

• Press the “ON” button for more than 2 seconds, the audible alarm will sound for 1 second and the UPS will start up.
• The UPS is set to ‘Normal mode’ after a few seconds. If the mains voltage is incorrect, the UPS will switch to ‘Battery mode’, without interrupting the power supply at the output terminals.
• Start the load or loads, making sure that the rated power of the device is not exceeded.

UPS startup without mains voltage.

• If it has a distribution board, set the input and output pro-tections to ‘On’.

• Press the “ON” button for more than 2 seconds, the audible alarm will sound for 1 second and the UPS will start up. The fan or fans, depending on the model, will start to func-tion.
  Then the main start screen will be displayed after a test of the device.

• The UPS is set to ‘Battery mode’ after a few seconds. Depending on the level of charge of the batteries, the re-sidual backup available may be very limited. Consider the risk involved in operating without mains and discharged batteries.
  If the mains voltage returns, the UPS will transfer to ‘Normal mode’ without interrupting the power supply at the output terminals.

• Start the load or loads, making sure that the rated power of the device is not exceeded.

UPS shutdown with mains voltage.

• Shut down the load or loads.

• Press the “OFF” button for more than 2 seconds to shut down the inverter. The audible alarm will sound for 1 second. The device will be set to ‘Bypass mode’.
  The output terminals will have voltage through the device’s internal static bypass block.

• To cut the UPS’s output voltage:

• Remove the input plug from the power socket,

• or simply turn the input and output protectors on the UPS’s distribution board to the ‘Off’ position (this ap-plies to any model).
  A few seconds later, the LCD screen turns off and the entire device will be out of service.

UPS shutdown without mains voltage.

• Shut down the load or loads.

• Press the ‘OFF’ button for more than 2 seconds to shut down the inverter. The audible alarm will sound for 1 second. The device will leave the output terminals without voltage.
  A few seconds later, the LCD screen turns off and the entire device will be out of service.

• To leave the assembly completely isolated, set the input and output switches of the board to ‘Off’.
