3 Introducere Instructiunile din acest manual se refera la celulele standardizate de MT tip UniAir. Pentru utilizarea corecta a cestui produs cititi acest manual cu atentie. Pentru montajul corect al accesoriilor si/sau al pieselor de rezerva consultati instructiunile din KIT-ul respectiv. Celulele UniAir sunt proiectate pentru o larga varietate de configuratii de instalare. Ele permit totusi si alte modificari tehnico-constructive - la cererea clientului. Din acest motiv, informatiile de mai jos pot uneori sa nu acopere unele aspecte ale configuratiilor cerute de client. Este deci necesar ca in afara acestui manual sa se consulte cea mai recenta documentatie tehnica (scheme, desene de fundatie, studii de coordonare a protectiilor, etc.) mai ales in legatura cu eventualele variante diferite de configuratiile standard. Toate operatiile privind montajul, punerea in functiune exploatarea si intretinerea trebuie executate decat de personal avand calificarea necesara. Pentru operatiile de intretinere utilizati decat piese de rezerva originale. Pentru alte informatii, consultati va rog catalogul tehnic, cod Introduction The instructions given in this manual refer to standardised UniAir type MV switchboards. For correct use of the product, please read this manual carefully. Please refer to the relative Kit sheets for correct assembly of accessories and/or spare parts. Like all the switchboards manufactured by us, the UniAir switchboards are designed for a large number of installation configurations. They do, however, allow further technical-construction variations (at the customer s request) to suit special installation requirements. For this reason, the information given below may sometimes not cover the instructions regarding special configurations requested by the customer. Apart from this manual, it is therefore always necessary to refer to the latest technical documentation (circuit diagram, wiring diagrams, foundation drawing, any protection co-ordination studies, etc.), especially with regard to any variations requested in relation to standardised configurations. All the operations regarding installation, putting into service, service and maintenance must be carried out by suitably qualified personnel with in-depth knowledge of the apparatus. Only use original spare parts for maintenance operations. For further information, please also see the technical catalogue, code

5 1. Ambalaj si transport 1. Packing and transport Respectati cu rigurozitate simbolurile si indicatiile de pe ambalaj Strictly follow the symbols and instructions indicated on the packing Fiecare sectiune (sau grup de unitati) este ambalat conform cerintelor de transport si depozitare, exceptand cazurile in care clientul are cerinte specifice. Fiecare grup este protejat cu o folie de plastic pentru a preveni infiltrarile de apa in timpul operatiunilor de incarcare descarcare si pentru indeparta praful in timpul depozitarii. Celulele sunt deobicei inaltate cu suporti de lemn fixati sub cele patru colturi. Celule sunt de obicei livrate cu carucioarele (intrerupatoare, transformatoare de masura) brosate, exceptand situatiile cand clientul nu doreste asta. Camionul care urmeaza sa transporte celulele trebuie sa aiba platforma la maximum 1,5 m inaltime pentru a nu se depasi inaltimea maxima de 4 m. Platforma de transport trebuie sa prezinte un coeficient ridicat de frictiune pentru a preveni alunecarea. Grupurile de celule trebuie plasate pe platforma spate in spate, transversal, cu materiale absorbante de presiune intre ele. Trebuie evitat contactul intre suprafetele diferitelor grupuri. Pe platforma trebuie plasate piese speciale pentru a distanta grupurile intre ele si pentru a preveni deplasarea longitudinala sau transversala. Diferitele grupuri trebuie ancorate de platforma cu franghii, astfel incat sa nu fie cauzate deformari sau rasturnarea la curbe sau franari bruste. Camionul de transport trebuie sa aibe platforma acoperita. Each section of the switchboard (or group of units) is packed according to shipping and storage requirements, except in cases of specific requests from the customer. Each group is protected by a plastic cover to prevent any infiltration of water during the loading and unloading stages in case of rain, and to keep the dust off during storage. The switchboards are normally raised off the ground by wooden supports fixed under the base in the four corners. The switchboards are generally shipped complete with trucks (circuit-breakers, instrument transformers) inserted in the relative compartments, except in the case of different agreements made with the customer. The truck for transporting the units which make up the groups must have its loading platform not more than 1.5 m above ground so as to fall within the maximum outline of 4 m. The loading platform must be slip-proof with a high friction coefficient. The layout of the groups on the loading platform must be made by placing them back to back transversely, placing materials to absorb compression and prevent any direct contact between the surfaces of the various groups between them. Special side members must be placed on the loading platform so that each group is spaced out and to prevent both longitudinal and transverse movement. The various groups must be anchored to the structure of the vehicle by ropes, so that no deformation is caused and tilting on bends or during violent stops is prevented. The transport truck must have a tarpaulin cover. 2. Controlul la receptie 2. Checking on receipt Nu solicitati partile izolante ale aparatelor in timpul manipularii celulelor. Inainte de executarea oricarei operatii verificati ca resoartele de actionare sunt descarcate si ca aparatele sunt in pozitie deschisa. Take care not to stress the insulating parts of the apparatus during handling of the cubicles. Before carrying out any operation, always check that the operating mechanism springs are discharged and that the apparatus is in the open position. Grupurile de celule trebuie descarcate din camion cu grija maxima conform descrierii de la capitolul 4.

14 5.4. Interblocaje 5.4. Interlocks Manevrele trebuie executate folosind o forta normala (< 200 Nm ). Daca nu sunt permise, nu trebuie fortate interblocajele ci trebuie verificata corectitudinea secventei de manevre. Blocajele sunt dimensionate sa reziste la o forta de 750 Nm fara deformari permanente sau fara a s e rupe. Operations must be carried out using normal activating force (< 200 Nm). Should they be prevented, do not force the mechanical interlocks and check that the operation sequence is correct. The locks are sized to resist a maximum activation force of 750 Nm without any permanent deformation or breakage. Aparatele prevazute a fi folosite in celule folosesc dispozitive de interblocare mecanica. Acestea sunt definite astfel: blocaje de forta blocaje preventive blocaje de siguranta (lacate si chei) Interblocaj separator de linie - CLP Este vorba de un blocaj mecanic care nu permite insertia manivelei de actionare decat daca sunt indeplinite conditiile corecte. Separatorul de legare la pamant poate fi inchis daca separatorul de linie este deschis. Se poate inchide separatorul de linie daca separatorul de legare la pamant este deschis Interblocaj intre CLP si usa. Este vorba de un blocaj mecanic de forta care previne deschiderea usii daca separatorul de legare la pamant este deschis. Pe de alta parte, nu este permisa deschiderea separatorului de legare la pamant daca usa este inchisa Interblocaj intre intreruptor si separatorul de linie E vorba de un blocaj de siguranta cu chei. Este impiedicata deschiderea separatorului de bara daca intreruptorul nu a fost deschis. Invers, intai trebuie inchis separatorul de linie si apoi intreruptorul Blocaje la cerere La cerere, pot fi montate urmatoarele blocaje pe separatoare: blocaje cu cheie blocaje electromecanice. The standardised apparatus foreseen on the switchboard widely uses mechanical interlocking devices. These are defined as: force locks prevention locks safety locks (padlocks/keys) Interlock line-side isolator - earthing switch This is a mechanical prevention lock which does not allow the operating lever to be inserted unless the conditions are correct. The earthing switch can only be closed if the line-side isolator is open. The line-side isolator can only be closed if the earthing switch is open Interlock earthing switch - door This is a mechanical force lock which prevents the door being opened if the earthing switch is open. On the other hand, it is not possible to open the earthing switch unless the door is closed Interlock circuit-breaker - line-side isolator This is a safety interlock with key. It prevents the busbar isolator from being opened unless the circuit-breaker has previously been opened. In reverse order, the busbar isolator must first be closed and then the circuitbreaker Locks on request On request, the following can be mounted on the operating seats of the isolators: key locks electromechanical locks. 1

Instructions for operating the apparatus and operation sequence of the units In timpul manevrelor de inchidere deschidere ale aparatelor cu protectii lipsa, mentineti o distanta de siguranta pentru a evita contactul cu piesele in miscare Toate manevrele, odata incepute, trebuie terminate si manivela indepartata din fanta de introducere. Manevrele trebuie efectuate utilizand o forta de actionare normala (< 200 Nm.). Daca nu sunt permise, nu fortati interblocajele, ci verificati corectitudinea secventei de manevrare. Blocajele sunt dimensionate sa reziste la o forta de actionare de 750 Nm fara a suferi deformari permanente sau ruperi. During the opening and closing operations of the apparatus with the protections missing, keep a safe distance away to avoid contact with moving parts. Once started, all the operations must be completed and the lever removed from the operating seat. The operations must be carried out using a normal activation force ( 200 Nm). If they are prevented, do not force the mechanical interlocks and check that the operation sequence is correct. The locks are sized to resist a maximum activation force of 750 Nm without any permanent deformation or breakage Istructiuni de manevrare a aparatelor 6.1.

Forta normal aplicata manivelei furnizate este de 160 N. In orice caz forta maxima aplicabila este 00 N HAD plug-in and withdrawable circuit-breakers The plug-in circuit-breakers (see fig. 5) available for UniAir switchboards, are basically derived from a fixed circuit-breaker to which the wheels, isolating contacts and release lever are applied. In the UniAir P1/E type cubicles, HAD-UniAir plug-in version circuit-breakers are used, whereas in the P1E/2R type cubicles an HAD-UniAir/2R withdrawable circuit-breaker is used. Withdrawal of the circuit-breakers can only take place under safe conditions, i.e. with the busbar isolators open and the earthing switches closed. Both the plug-in and withdrawable circuit-breaker are fitted with release lever which prevents withdrawal with the circuit-breaker closed. To facilitate withdrawal of the circuit-breakers, a special circuitbreaker withdrawal truck is available. The HAD-UniAir plug-in version circuit-breaker can take up the following positions: Connected: Main circuits and auxiliary circuits connected Withdrawn: Main circuits and auxiliary circuits disconnected. Circuit-breaker completely withdrawn from the compartment. The HAD-UniAir/2R withdrawable version circuit-breaker can take up the following positions: Connected: Main circuits and auxiliary circuits connected Isolated: Main circuits disconnected auxiliary circuits connected (Test position) Main circuits disconnected auxiliary circuits disconnected (Completely isolated) Withdrawn: Main circuits and auxiliary circuits disconnected. Circuit-breaker completely withdrawn from the compartment. Circuit-breaker operation can be either manual or electric Closing spring charging in the operating mechanisms with manual charging. Make the coupling position of the lever (supplied) coincide with the charging shaft ().

Automatic closing spring charging When connected to the power supply, the operating mechanism automatically charges the closing springs, signalling completion of the operation with the appearance of the yellow signal in the window (9). To avoid excessive current absorption in the case of an installation with several motor operators, it is advisable to charge one operating mechanism at a time. Manual charging of operating mechanisms with automatic charging When the lever is inserted, the automatic charging movement is released: charging as indicated previously can then be carried out. On completion of charging, remove the lever. Should the motor start during the manual charging operation, continue the operation in any case, completing it manually. When charging is completed the motor stops. Do not withdraw or insert the lever if the motor is working. If the motor has stopped due to tripping of the protection circuit-breaker, complete the charging manually before closing the circuitbreaker again. Closing operation Check that the operating mechanism springs are charged [yellow flag in the window (9)]. Turn the closing knob (4) clockwise. Closing is indicated by the letter I appearing in the red field in the window (6).
