4.2.12 ARBC (Auxiliary Remote Bypass Contact) The Archimod HE 240-480 makes it possible to enable forced bypass operation of the UPS without performing any operation from the control panel but simply by means of a normally open external contact. The external bypass contact terminal is found on the DIN rail at the top left in the UPS cabinet having the connection busbars. For the correct connection of the external contact, the following requirements must be adhered to: - use a double-insulation cable of up to 10 meters in length; - make sure that the switch used is galvanically isolated. The electric characteristics of the auxiliary remote bypass contact are the following: - voltage with open contacts: less than 100 V - current with closed contacts: less than100 mA The figure below shows how the external bypass contact must be connected:

4.3 Insertion of power modules Once all the electrical connections have been made, all the UPS panels can be screwed up again and the power modules can be inserted in the UPS. Insert the power modules one at a time checking that they abut. Fix them to the frame with the two screws provided with each module , making sure that they are tightly fixed. Use the SHC M4x20 screws (hex socket head). The two fixing screws also act as the module’s earth connection and must both be fixed for safety purposes. If one or more power modules is not installed, the free slots must be covered by putting the plastic cover of the kit 3 108 66 in each of them. The cover must be fixed with two TCEI M4x20 screws.

5. Configuration and Start-up DANGER All the configurations and start-up operations may only be done by a SKILLED TECHNICIAN (paragraph 2.2.1).

5.1 Introduction This chapter contains all the information necessary for a correct configuration of the Archimod HE 240-480 HE UPS and for its subsequent startup. The factory configuration provides for THREE PHASE INPUT and 120° THREE PHASE OUTPUT.

5.2 Input configuration The Archimod HE 240-480 automatically recognises the voltage, frequency and number of phases on input. No further configuration by means of the control panel is therefore necessary. CAUTION Make sure the neutral wire is always connected.

5.3 Output configuration During the start-up, select from the control panel the type of output voltage according to the applied load. The default configuration for the Archimod HE 240-480 is 120° three phase 400 Vac. Two different settings can be selected to manage the three phases: - THREE PHASES 120°: this is the default setting and is usually used if three phase loads are applied on the UPS output (e.g. three phase electrical motors) or if there are both three phase and single phase loads. The UPS manages the three output phases protecting the three phase load. For example, if an excessive load is applied to one of the three output lines, the automatic bypass switches all three lines on output. - THREE SINGLE PHASE OUTPUTS: this setting is necessary if three single phase output lines with the neutral in common have been created. The UPS manages the three outputs completely independently of each other. For example, if an excessive load is applied to one of the three output lines, the bypass only cuts in on the overloaded line while the power supply continues to be guaranteed on the other two by the UPS. For the correct selection of the output configuration, follow the instructions given in paragraph 5.5.

5.4 Pre-start-up checks Before powering the equipment, carry out the following checks: 1. Check that the mains input disconnector of the UPS is open (OFF position). 2. Check that the bypass input disconnector of the UPS is open (OFF position). 3. Check that the battery disconnectors of the external battery units are open. 4. Check that the maintenance bypass disconnector and the output disconnectors of the UPS are open (OFF position). 5. Check that the input and output wiring has been done and that all the connections have been tightened up properly. 6. Check the correct phase sequence of the mains input and bypass line (if separate). 7. Check that the parameters (voltage and frequency) of the mains input are compatible with those shown on the UPS rating plate. 8. Check that all the power modules are inserted properly and that the fixing screws of the power modules are present and screwed up to abut the relative slots (use SHC M4x20 screws with hex socket head).

50



CAUTION If fewer power modules are inserted than the maximum, protect the empty slots with the plastic covers of the kit 3 108 66.

CAUTION Never select the “Single Phase” option because it is not supported. CAUTION Wrong connections or incorrect output configurations may cause injury and/or damage. 6. Follow the path UPS Setup  Output  Voltage and UPS Setup  Output  Frequency to check that the voltage and the frequency set are the ones required. CAUTION Archimod HE 240-480 is configured as default with strings of batteries in common. When installing with independent strings of batteries (separate for each command board), contact the LEGRAND Technical Support Service to obtain the installer password and the configuration instructions. The type of battery installation is configured following the path UPS Setup  Batteries  Common battery after entering the password supplied by the LEGRAND Technical Support Service. 7. Follow the path UPS Setup  Batteries  Total KB to select the correct number of KB (Battery Kits) installed. INDICATION 1 KB (Battery Kit) represents a string of 21 batteries in series. Each external battery unit with a string of 21 batteries represents 1 KB. When installing with independent strings of batteries, the KB value must be entered for each command board. Example: if an Archimod HE 240 is connected to four external battery units in common, each containing 21 94Ah batteries, a value of 4 KB must be set. If the four external battery units are independent, set the value of 1 KB for each of the command board addresses. 8. Follow the path UPS Setup  Batteries  Capacity to select the correct value of the capacity in Ah of the individual KB. INDICATION The UPS calculates the total battery capacity as produced by the total KB * Capacity. When the configuration is with independent strings of batteries, the capacity value must be entered for each command board. Example: if an Archimod HE 240 is connected to four external battery units in common, each containing 21 94Ah batteries, a value of 94Ah must be set. If the four external battery units are independent, set the value of 94Ah for each of the command board addresses. 9. Leave the Service Mode pressing the ON/OFF key. 10.

5. Configuration and Start-up Press the ENTER key to update the modules and complete the start up phase. Press the ESC key to interrupt the update and start-up procedures. If no operation is carried out within 30 seconds, the UPS turns off. 12. Wait for the backlit status indicator on the control panel to show a steady green light. 13. Check that the output voltage and frequency values set correspond with the requirements of the applied load. If this is not the case, insert the values necessary (see the user manual). 14. Close the output disconnector (position ON) of the UPS. At this point, the load is powered by the UPS. 15. Close the UPS doors and remove the key. INDICATION If during the installation phase it is necessary to check the proper functioning of the UPS in stored energy mode, remove the mains by means of the breaker placed upstream of the UPS. CAUTION Do not remove the power modules during the functioning of the UPS without first having activate the proper hot-swap procedure (described in paragraph 6.4). The removal of one or more power modules without the proper use of the hotswap procedure could damage the equipment. CAUTION The keys for opening the UPS doors must not be left at the operator’s disposal. WARNING The installation and maintenance manual must not be left at the disposal of the operator.

5.6 ECO MODE setup The Archimod HE 240-480 has a functioning mode called “eco mode”, in which the load is supplied directly from the electrical mains through the automatic bypass circuit inside the power modules. If the output voltage leaves the window of tolerance (-20% / +15% of the voltage set on output), the UPS actuates its inverter stage and supplies the load with energy stored in the batteries. When the input mains are back within the tolerance values, the UPS is automatically taken back to the eco mode. It is possible to change the functioning mode between on-line and off-line mode (and vice versa) both with UPS on and with the UPS off (through the “Service Mode” function menu). To activate the eco mode, enter the main menu and follow the path UPS Setup  Bypass  Off-line Mode. Select “Enabled” and press the ENTER key to confirm the choice. To return to the on-line mode, enter the main menu and follow the path UPS Setup  Bypass  Off-line Mode. Select “Disabled” and press the ENTER key to confirm the choice. INDICATION If the load needs to be supplied with a voltage without disturbances or with a voltage regulated in amplitude and/or frequency it is necessary to use the UPS in double conversion on-line mode.

5.7 EMERGENCY POWER SYSTEM (EPS) MODE setup The Archimod HE 240-480 has an “emergency power system” functioning mode that is useful for example to power an emergency lighting system. When there is input from the mains, the UPS output is disabled. If the mains input is missing, the output is supplied by the UPS functioning with batteries. It is possible to enable or disable the EPS function only in Service Mode (with the UPS off ). The path to follow is UPS Setup  Options  EPS mode. Select “Enabled” of “Disabled” and press the ENTER key to confirm the choice.

Close all battery disconnectors of the external battery units. 3. Close the mains input disconnector and bypass input disconnector by bringing them to the ON position. 4. Press the ON/OFF key to turn on the UPS. When the display shows the text “ to confirm UPS turn ON”, press the ENTER key. CAUTION Archimod HE 240-480 is able to recognise the presence of non aligned firmware among the power modules and therefore prevent the start-up. If the firmware of the power modules is out of alignment, the status indicator flashes red rapidly and the display shows the text “Invalid PM SW Versions: to execute update”. Press the ENTER key to update the power modules and complete the start up phase of the UPS. Press the ESC key to interrupt the update and start-up procedures. If no operation is carried out within 30 seconds, the UPS turns off. 5. Wait for the power-on procedure to be completed. The main screen is shown on the display. In this condition the load is supplied directly by the bypass line. The display shows the text “Manual Bypass” and “Forced on Bypass”. The backlit status indicator becomes orange. 6. Open the output disconnector by bringing it to the ON position. 7. Open the maintenance manual bypass disconnector by bringing it to the OFF position. 8. Enable the UPS in inverter (on-line) mode. Enter the main menu and follow the path UPS Setup  Bypass  Forced Mode. Set the value of the parameter to “Disabled” with the ARROW UP/DOWN keys. Press the ENTER key to confirm. 9. At the end of the procedure the load is powered by the UPS. Under these conditions the backlit indicator shines green. 10. Close the UPS doors (the keys must not be left at the operator’s disposal).

6.4.3 Maintenance procedure with UPS off CAUTION The shutdown procedure must be applied only if the load is off or does not need to be powered by the UPS. 1. Keep the ON/OFF key pressed for at least two seconds. 2. When the display shows the text “Turn off the UPS?”, press the ENTER key. 3. Wait for the shutdown operations to complete. 4. Open the output disconnector by bringing it to the OFF position. 5. Open the mains input disconnector and bypass input disconnector by bringing them to the OFF position. 6. Open the battery disconnectors of the external battery units. 7. Press the ON/OFF key to discharge any internal capacity. 8. Open the circuit breaker upstream of the UPS which supplies power from the mains. If these operations are performed correctly, there will be no voltage to the UPS. It is now possible to proceed with the maintenance operations. WARNING Inside the drawer where the command boards and the relay interface card are located there could be dangerous voltage due to the connection of the external backfeed control line. Be careful of connector EC9 of the relay interface card to which the backfeed line is connected.

Note: by making the external backfeed protection as per the diagram in paragraph 4.2.6, it is possible to isolate the line from outside and make it safe.

6.5 Replacing the fuses and surge arrester (DIN rail) A surge arrester and two fuse holders can be found in the DIN rail inside the cabinet with the UPS connection busbars. The first fuse holder, containing a 16 A fuse, is in series to the surge arrester. The second fuse holder, containing a 2 A fuse, is in series to the input bypass disconnector release coil.

6. Maintenance If necessary replace the fuses and the surge arrester as indicated in the following picture:

6.6 Requirements for external battery units When performing maintenance on the external battery units with the UPS in normal mode the latter must be placed in manual maintenance bypass mode. CAUTION During operation in manual maintenance bypass mode, the load is not protected because it is supplied by the bypass input line. INDICATION If the installation/removal procedure changes the total number of KB installed, it is necessary to update this setting from the control panel. After concluding the installation/replacement operations, calibrate the batteries from the control panel to get precise indications regarding the total autonomy of the UPS. To activate the function, enter the main menu and follow the path Tools  Batteries  Batt. Calibration. Press the ENTER key to confirm the choice.

6.7 Extraordinary maintenance Contact the LEGRAND Technical Support Service if faults have occurred which require access to internal parts of the UPS.

7. Warehousing DANGER All storage operations may only be done by a SKILLED TECHNICIAN (paragraph 2.2.1). DANGER A SKILLED TECHNICIAN must check that there is no voltage present before disconnecting the cables. All the battery isolator switches on the external battery units must be open.

7.1 UPS The UPS must be stored in an environment with a room temperature between -20°C (-4°F) and +50°C (+122°F) and humidity less than 90% (not condensing).

7.2 Batteries It is possible to store VRLA batteries without recharging them in the following conditions: - up to 6 months at +20°C (+68°F); - up to 3 months at +30°C (+86°F); - up to 2 months at +35°C (+95°F). Contact a skilled technician if the batteries must be recharged. CAUTION The external battery units must never be stored if the batteries are partially or totally discharged. LEGRAND is not liable for any damage or bad functioning caused to the UPS by wrong warehousing.

8. Dismantling DANGER Dismantling and disposal operations may only be done by a SKILLED TECHNICIAN (paragraph 2.2.1) The instructions in this chapter are to be considered indicative: in every country there are different regulations with regard to the disposal of electronic or hazardous waste such as batteries. It is necessary to strictly adhere to the standards in force in the country where the equipment is used. Do not throw any component of the equipment in the ordinary rubbish.

8.1 Batteries disposal Batteries must be disposed of in a site intended for the recovery of toxic waste. Disposal in the traditional rubbish is not allowed. Apply to the competent agencies in your countries for the proper procedure.

Pb WARNING A battery may constitute a risk of an electric shock and high short-circuit current. When working on batteries, the prescriptions indicated in chapter 2 must be adhered to.

8.2 UPS dismantling The dismantling of the UPS must occur after the dismantling of the various parts it consists of. For the dismantling operations, it is necessary to wear the Personal Protective Equipment mentioned in paragraph 2.3 and to consult the instructions and diagrams in the installation and maintenance manual. Sub-divide the components separating the metal from the plastic, from the copper and so on according to the type of selective waste disposal in the country where the machine is dismantled. If the dismantled components must be stored waiting to be taken to the dump, be careful to keep them in a safe place protected from atmospheric agents to avoid soil and groundwater contamination.

8.3 Electronic component dismantling For the disposal of electronic waste like the control panel or the command boards it is necessary to refer to the relevant standards.
