Flange and metal plates
If flange plates have to be dismantled, (e.g. to
drill entry holes), they shall be put back in
such a way that the IP protection is
maintained. Ensure that the sealing element
fits snugly.
PE conductors fed from outside are to be
connected to the PE terminal provided on
the flange.
Warning: Metal flanges, metal plates and
metal glands shall be incorporated in the
potential equalization.

Before putting the apparatus into operation,
the tests specified in the individual national
7
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,
5
signal lamps, pushbuttons, etc.) shall be
checked in accordance with these operating

instructions and other applicable regulations.
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
control gear 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
M10 x 55
(EN 60079-17).
M12 x 30
Prior to opening the enclosure, it is
M10
necessary to ensure that the voltage supply
M12
has been isolated or to take suitable
M 12
protective measures.

In the case of intrinsically safe circuits, it is
permissible to carry out work while the circuit
is live.
The necessary intervals between servicing
depend upon the specific application and
shall be stipulated by the operator according
to the respective operating conditions.
During servicing, above all the correct state of
parts on which the explosion protection
depend, (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.
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 CEAG parts shall be used for
carrying out repairs.
Repairs that affect the explosion protection
may only be carried out by CEAG or by a
qualified electrician in compliance with the
respective national regulations
(EN 60079-19).
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 manufacturer.
In the event of damage to the flameproof
encapsulation of control components,
replacement of these components is
mandatory. In case of doubt, the respective
apparatus shall be sent to CEAG for repair.
When replacing these individual built-in
components (measuring instruments,
pushbuttons, etc.), point 6.2 "Opening
apparatus / Electrical connection" shall be
observed.
9
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 for the type of plastic used.
The product range is subject to changes and
