Mounting

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 (Test torque 2.5 Nm).
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.

6.1 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.
Two conductors with pin lugs in one terminal,
have to connect as in Fig.1 shown.
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 interna-
tional regulations (e.g. use of cable end sleeves).
All screws and/or nuts of the connection
terminals, including those not in use, shall be
tightened down securely.

6.2 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 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 and IEC/EN 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.
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 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

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 /
EATON branch.
Subject to modifications or supplement of the
