Instructiuni Pentru Operarea Intrerupatorului - ABB HD4/ESB Series Installation And Service Instructions Manual

6. Instructiuni pentru operarea
intrerupatorului
6.1. Indicatii pentru protectia muncii
Intrerupatorul HD4 asigura un grad minim de pro-
!
tectie de IP2X daca este instalat in urmatoarele
conditii:
– versiunea fixa, cu sistem de protectie
– versiunea debrosabila, instalat in celula.
In aceste conditii, operatorul este complet prote-
jat impotriva contactului accidental cu partile in
miscare.
Daca trebuie realizata o operatie cu intrerupatorul
scos din celula sau cu sistemul de protectie ne-
realizat, trebuie asigurata o atentie marita la orice
parte aflata in miscare.
Daca anumite operatii nu pot fi realizate trebuie ve-
rificat ce secventa acestora este corecta si nu
se forteaza interblocajele mecanice.
Operatiile de brosare si de debrosare trebuie
realizate gradual pentru a se prevenii orice
impact care poate deforma interblocajele mecanice.

6. Instructions for circuit-breaker
operation
6.1. Safety indications
HD4 circuit-breakers ensure a minimum degree of
!
protection IP2X if installed under the following
conditions:
– fixed version, with protection netting
– withdrawable version, installed in a switchboard.
Under these conditions, the operator is fully
guaranteed against accidental contact with moving
parts.
Should any mechanical operations be carried out
on the circuit-breaker outside the switchboard or
with the protection netting removed, be very careful
of any moving parts.
If the operations are prevented, do not force the
mechanical interlocks and check that the operation
sequence is correct.
The racking-in and racking-out operations of the
circuit-breaker must be carried out gradually to
prevent any impacts which might deform the me-
chanical interlocks.
