Installation; Mounting; Opening The Device/Electrical Connection; Cable Entries (Kle); Blanking Plugs - Eaton CROUSE-HINDS Série Mode D'emploi

The user alone is responsible for the appropriate use of this plug and
socket system in consideration of the basic conditions existing at the
plant (see technical data).
After a short in the circuit, the functioning of the plug and socket
system and of the plugs has to be checked.
Since the switch contacts can no more be checked because of the
flameproof enclosure, the complete switch insert (flange socket) will
have to be replaced after repeated short circuits.

Installation

For the mounting and operation, the respective national regulations as
well as the general rules of engineering will have to be observed
(IEC/EN 60079-14).
The improper installation and operation of plugs and sockets may result in
the invalidation of the guarantee.
6.1

Mounting

The wall sockets can be mounted without opening their enclosure.
If an ambient temperature between -40 °C and -55 °C is to be expected
X
ATEX - IEC
when used as intended, the wall sockets may only be installed in a
protected location. The impact energy shall not exceed 4 joules.
In case the wall sockets are mounted directly onto the wall, they may rest
evenly only at the respective fastening points. The chosen screw shall
match the fastening hole (see dimensional drawing) and it must not
damage the hole (e. g. use of a washer).
The device shall be fastened diagonally with at least 2 screws.
The wall sockets, flange sockets and couplers shall be mounted so
that the plug hole points downwards (see page 18, fig. 2).
The wall sockets can be clipped onto the Cooper Crouse-Hinds mounting
plate size 4. They are laterally pushed into the guiding groove on the
left-hand side of the mounting plate.
The respective mounting instructions will have to be observed.

6.2 Opening the device/ Electrical connection
Before opening the apparatus, ensure that it has been isolated from
the voltage supply, or take appropriate protective measures.
The electrical connection of the device may only be carried out by
skilled staff (IEC/EN 60079-14).
The conductors shall be connected with special care in order to
maintain the explosion category.
The insulation of the conductors shall reach up to the terminal. The
conductor itself shall not be damaged.
The connectible min. and max. conductor cross-sections shall be
observed (see technical data).
Taking into account the respective regulations, the properly bared
conductors of the cables shall be connected.
The plug insert (page 18, item 2, fig. 4) is removed from the pin bushing
(page 18, item 1, fig. 4), after the fastening screws (item 3, fig. 3) have
been unscrewed. Thereafter, the plug insert can be connected to the
connections of the plug pins (see page 18, view 1, fig. 4).
Attention: When the fastening screws (page 18, item 3, fig. 3) get lost,
they will have to be replaced by similar screws or to be ordered
directly from the manufacturer.
Assembly is made in inverse order, after the cable has been connected.
To connect the coupler, unscrew and remove the 4 fixing screws of the
flange from the body sleeve. The coupler insert can then be connected to
the respective contacts.
When reassembling, the flange screws shall be screwed into the body
sleeve with a maximum test torque of 1 Nm.
All screws and / or nuts of the supply terminals, also of those remaining
vacant, shall be tightened down.
Excessive tightening may affect or damage the connection.
The supply terminals are designed for the connection of copper conduc-
tors.
If multi- or fine-wire connecting cables are used, the wire ends will have
to be handled in acc. with the applicable national and international rules
(e.g. use of sleeves for strands).
6.3

Cable entries (KLE); blanking plugs

6.3.1 Socket

Generally, only certified cable entries and blanking plugs are
permitted for use. Flexible cables shall be used with trumpet-shaped
cable glands or other suitable entries with additional pull-relief.
When using cable entries with a lower IP protection than that which
applies to the device (see technical data), the IP protection of the whole
device will be reduced. The mounting directives applicable to the cable
entries used shall be observed.
Unused holes shall be closed with a certified blanking plug in order to
establish the minimum protection category. Care has to be taken that
when fitting the cable entries, sealing inserts appropriate to the cable
diameter are used.
In case of sealing inserts that are cut out, it shall be ensured that the
insert is properly adapted to the cable diameter.
In order to ensure the required minimum protection category, the cable
glands are to be tightened down.
