Item 1
Important: When using these modules,
the technical data and the connection
diagram on the type label shall be
observed.
When circuit breakers and ELCBs (RCDs)
are flameproof encapsulated in the
enclosures, after several short circuits it is
necessary to test the modules to ensure that
they function correctly. An ELCB(RCD) does
not prevent the feeling caused by an electric
shock, but limits the duration of the current
flow through the human body to such an
extent that the probability of its being fatal is
reduced to a negligible value.
After the cause for tripping has been
eliminated, reset the ELCB (RCD) by
switching the toggle switch to the "ON"
position.
The manufacturer of the ECD (ELCB)
recommends to test the function by the
test button Fig. 1, Item 2, twice yearly.
A signal contact (optional) on a circuit breaker
or ELCB is actuated by an overload, earth
fault or short circuit. It cannot, however, be
tripped if the circuit breaker is switched
manually.
When switching on the signal contact, first of
all the actuating switch of the circuit breaker,
Fig. 1, Item 3, has to be switched on. After
this, the rotary switch of the signal contact,
Item 1, can be actuated.
When special switch or control units are
flameproof-encapsulated in these module
enclosures, details relating to the properties
and use of these modules shall be taken from
the respective supplementary sheet.
Adequately marked special versions of the
control units can be operated in „intrinsically
safe circuits". The electric limiting values
applicable to „intrinsic safety" shall be
observed.
The data according to sections 3 and 4
shall be taken into account during use.

Cooper Crouse-Hinds GmbH
Flameproof module series, GHG 61. .... R....
Applications other than those described
are not permissible without a written
declaration of consent from the
manufacturer.
Item 2
During operation the instructions stated
in section 7 of the operating instructions
shall be observed.
The sole responsibility with respect to the
suitability and proper use of these
modules lies with the operator.
6.1

Mounting

Item 3
Before mounting the modules, it is necessary
to check them to ensure that they are in
perfect condition. Special attention shall be
given to any possible transport damages
(cracks and damage to the flameproof
encapsulation or any other damage to the
modules).
The modules can be mounted by snapping
them onto a DIN rail or screwing them onto an
internal mounting plate.
When mounted directly onto an internal
mounting plate, the enclosures shall be fixed
in such a way that they rest evenly on the
fastening points provided for this purpose
and that they cannot turn.
The screws used shall match the fixing hole
(see dimensions drawing) and shall not
damage the hole (e.g. use of a washer).
If the fixing screws are overtightened, the
apparatus may be damaged.
6.2

Electrical connection

The electrical connection of the apparatus
may only be carried out by trained staff.
The properly bared conductors of cables
shall be connected with due regard to the
respective regulations.
To maintain the explosion protection, con-
ductors 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
accordance with the valid national and
international 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.
7 Maintenance / Servicing
The valid national regulations for the
servicing / maintenance of electrical
apparatus for use in potentially explosive
atmospheres shall be observed the EN
60079-17 and 60079-19.
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 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.
