Instalarea - ABB HD4/ESB Series Installation And Service Instructions Manual

7. Instalarea

7.1. Generalitati
Instalarea corecta este foarte importanta. Si din
!
acest motiv instructiunile date de catre furnizor
trebuie urmarite si aplicate cu strictete. In timpul
instalarii se recomanda a folosii manusi pentru
manevrarea diferitelor parti componente.
7.2. Conditii normale de instalare
Temperatura maxima admisibila
Temperatura minima admisibila
Umiditatea relativa
Altitudine
Poate fi necesara ventilarea camerei in care se face instalarea.
Pentru alte conditii de instalare, va rugam sa urmati indicatiile
din Standerdele (IEC 60694). Pentru cerinte de instalare
speciale va rugam sa ne contactati.
Zonele in care apar treceri cu conductoare electrice trebuie
protejate impotriva accesului animalelor care ar putea cauza
stricaciuni sau functionarea anormala a instalatiilor.
7.3. Operatii preliminare
– A se curata partile izolante cu o carpa uscata si curata.
– A se verifica ca terminalul superior si cel inferior sunt cu-
rate si nu prezinta deformari cauzate de lovituri in timpul
transportului sau depozitarii.
7.4. Instalarea intrerupatorului in varianta fixa
Intrerupatorul se poate monta direct pe suportul pus la
dispozitie de catre client.
Intrerupatorul, completat cu caruciorul suport, trebuie fixat
podeaua compartimentului cu tije speciale.
Partile suprafetei pe care circula rotile caruciorului trebuie
sa fie perfect nivelate.
Zonele pe care rotile cadrului suport sau ale caruciorului
circula trebuie sa fie in acelas plan orizontal pentru a
preintampina orice risc de disporsionare in suportul intre-
rupatorului.
Trebuie asigurat un grad minim de protectie (IP2X) de la
partea frontala la partile sub tensiune.
7.5. Instalarea intrerupatorului in var. debrosabila
Intrerupatoarele debrosabile sunt pregatite pentru instalare
casetele CBE sau diferite tipuri de celule.
Introducerea sau tragerea intrerupatorului trebuie facuta
gradual pentru a prevenii orice soc care ar putea deforma
interblocajele mecanice.
Daca nu este posibila actionarea intrerupatorului, acesta nu
trebuie fortat si trebuie verificat daca secventa de actionare
este corecta. Forta necesara pentru tragerea/introducerea
intrerupatorului este de 260N. In cazuri extreme, forta ce
trebuie aplicata nu trebuie sa depaseasca 400N.

7.2. Normal installation conditions
+ 40 °C Maximum ambient air temperature
– 5 °C Minimum ambient air temperature
% < 95 Relative humidity
< 1000 m Altitude
It must be possible to ventilate the installation room.
For other installation conditions, please follow what is indi-
cated in the product Standards (IEC 60694). For special
installation requirements please contact us.
The areas affected by the passage of power conductors or
auxiliary circuit conductors must be protected against the
possible access of animals which could cause damage or
anomalous service.
7.3. Preliminary operations
– Clean the insulating parts with clean dry rags.
– Check that the upper and lower terminals are clean and free
of any deformation caused by shocks received during
transport or storage.
7.4. Installation of fixed circuit-breaker
The circuit-breaker can be mounted directly on the supporting
frames provided by the customer.
The circuit-breaker, complete with supporting truck, must be
fixed to the floor of its compartment with special brackets.
The parts of the floor surface on which the truck wheels rest
must be perfectly level.
The areas on which the supporting frames or truck wheels rest
(if a truck is provided) must be on the same horizontal plane to
avoid any risk of distortion in the breaker frame.
Fit the isolating partitions if provided.
A minimum degree of protection (IP2X) must be guaranteed
from the front towards live parts.
7.5. Installation of withdrawable c.-breaker
The withdrawable circuit-breakers are preset for insertion in
CBE enclosures, in CBE fixed parts or in the corresponding
switchboards.
Insertion and racking-out of the circuit-breakers must be gradual
to avoid any shocks which could deform the mechanical inter-
locks.
If the operations are prevented, do not force the interlocks and
check that the operating sequence is correct. The force nor-
mally applicable to the insertion/racking-out lever is 260 N. In
any case, the maximum applicable force must never exceed
400 N.
Correct installation is of prime importance. The
instructions given by the manufacturer must be
carefully studied and followed. It is good practice to
use gloves to handle the pieces during installation.
