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
7
components (measuring instruments, signal
8
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
5
operation. If necessary, the measuring
instrument needle shall be set to zero using the
5 9 6
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
(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.
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
(IEC/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 manufac-
turer.
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.

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
