6.2 Electrical connection
The electrical connection of the apparatus may
only be carried out by trained staff
(IEC/EN 60079-14).
The properly bared conductors of cables shall be
connected with due regard to the respective
regulations.
To maintain the explosion protection, conductors
shall be connected with special care.
The insulation shall reach up to the terminal. The
conductor itself must not be damaged.
The minimum and maximum connectable
conductor cross sections are to be observed.
All screws and/or nuts of the connection
terminals, including those not in use, shall be
tightened down securely.
The built-in standard terminal is designed for the
direct connection of conductors with copper
wires.
The circuit diagram of the built-in components is
shown on the modules, included with the switch
unit or included in the operating instructions. In
the case of wired installations or distributions,
the connection diagram included with the
apparatus shall be observed.
When using multi- or fine-wire connection
cables, the wire ends shall be treated in

tional regulations (e.g. use of cable end sleeves).
6.3 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 modules
shall be checked in accordance with these
operating instructions and other applicable
regulations.
The incorrect installation and operation of
distributions can result in the invalidation of the
guarantee.

Maintenance / Servicing
The valid national regulations for the servicing /
maintenance of electrical apparatus for use in
potentially explosive atmospheres shall be
observed the IEC/EN 60079-17.
Prior to opening the enclosure, it is necessary to
ensure that the voltage supply has been isolated
or to take suitable protective measures.
Only original EATON / COOPER CROUSE-HINDS
GMBH spare parts may be used!
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 shall be checked.
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 EATON / COOPER CROUSE-
HINDS GMBH parts shall be used for carrying
out repairs.
In the event of damage to the flameproof
encapsulation, replacement of the respective
components is mandatory. In case of doubt, the
respective apparatus shall be sent back to the
manufacturer for repair.
Apparatus modifications or design changes are
not permitted.

Disposal / Recycling
The respective valid national regulations for
waste disposal shall be observed when
disposing of apparatus.
To facilitate recycling of individual parts, parts
made of moulded plastic shall bear the marking
