Putting into operation

Before putting the apparatus into operation,
the tests specified in the individual national
regulations shall be performed�
In addition to this, before being put into
operation, the correct functioning of the
apparatus and of the built-in components
(measuring instruments, signal lamps,
pushbuttons, etc�) shall be checked in
accordance with these operating instructions
and other applicable regulations�
At temperatures below -20° C it is important
to make sure that their is no explosive
atmosphere in the surrounding of the
distri butions. Observe relevant labels on the
distributions. For distributions with internal
heating, the switch on standby is signaled
by the thermostat.
The zero setting of the measuring instrument
needle shall be checked before putting it into
operation� If necessary, the measuring
instrument needle shall be set to zero using the
adjustment screw�
The incorrect installation and operation
of distributions can result in the invalidation
of the guarantee.

Maintenance / Servicing

The valid regulations EN/IEC 60079-17 for
the servicing / maintenance of electrical
apparatus for use in potentially explosive
atmospheres shall be observed.
Prior to opening the enclosure, it is
necessary to ensure that the voltage supply
has been isolated or to take suitable
protective measures.
In the case of intrinsically safe circuits, it is
permissible to carry out work while the circuit is
live�
The user is responsible for stipulating the
necessary maintenance intervals specific to
the application depending on the conditions
of use, national directives and standards.
Should the maintenance interval for the
function test of an RCB (ELCB) not be
defined, the manufacturer of the ECD (ELCB)
recommends to test the function by the test
button twice yearly.
The ELCB (RCD) shall release when the test
button is actuated. If this is not the case, the
protective function is no longer guaranteed
and the ELCB (RCD) shall be replaced.
During servicing, above all the correct working
order of parts on which the explosion protection
depends, (e�g� intactness and efficiency of the
flameproof components, the enclosure, the
seals and cable entries), and the switch
mechanism function of the control switches
shall be checked�
Screws, lock nuts, connection terminals, screw
connections, cable entries, etc� have to be
controled for tightness�
If, in the course of servicing, it is ascertained,
that repairs are necessary, section 8 of these
operating instructions shall be observed�

Repairs / Modifications

Only original CCH / EATON parts shall be
used for carrying out repairs.
In the event of damage to the flameproof
encapsulation, replacement of the respec-
tive components is mandatory. In case of
doubt, the respective apparatus shall be
sent back to the manufacturer for repair.
Repairs that affect the explosion protection
may only be carried out by CCH / EATON or
by a qualified electrician in compliance with
the respective national regulations
(EN/IEC 60079-19).
Ex-d components in Ex-e distribution boxes may
only be replaced by components of the same
type (electrical ratings and mechanical size)�
When replacing these individual built-in
components (flameproof circuit breakers,
contactors, measuring instruments, pushbut-
tons, etc�), section 6�2 "Opening apparatus /
Electrical connection" shall be observed�
Apparatus modifications or design changes are
not permitted; excepted from this are the fitting
of additional cable entries and the installation of
connection terminals within the scope of the
approvals for the respective apparatus or
according to details laid down by the manu-
facturer�

Disposal / Recycling

When the apparatus is disposed of, the
respective national regulations on waste
disposal will have to be observed�
In case of disposal you can obtain additional
information from your Cooper Crouse-Hinds /
