Explosion-protected plugs and sockets
63A, GHG 514
The plug can be pushed into the socket and
pulled out of it only whilst the socket is
switched off.
The data as per point 3 and 4 will have to be
taken into account with the use.
Applications other than described are not
permitted without Eaton's Crouse-Hinds
Business / CEAG's prior written consent.
For the operation, the instructions stated in
section 7 of the operating instructions will have
to be observed.
From time to time, the locking function
protecting against inappropriate use e. g. of
industrial plugs in zone 1, has to be checked.
In the open air, the plugs must be kept with the
plug opening (pin side) pointing downwards or
be closed with protective plug caps available as
an optional extra (see general catalogue).
The user alone is responsible for the appropri-
ate 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
7
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,
9
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 (e. g. Betr.Si.V, equipment
safety law for Germany) as well as the general
rules of engineering will have to be observed
(IEC/EN 60079-14).

6.1

Mounting

The wall sockets can be mounted without
opening their enclosure.
5
In case the wall sockets are mounted directly
onto the wall, they may rest evenly only at the
respective fastening points. The chosen screw
7
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 shall be mounted so that the
plug hole does not points upwards (fig. 2).

Electrical connection

The electrical connection of the device may only
be carried out by skilled staff.
The insulation of the conductors shall reach up
to the terminal. The conductor itself shall not
be damaged.
EATON's Crouse-Hinds Business
Taking into account the respective regulations,
the properly bared conductors of the cables
shall be connected.
Fig. 3 + 4, page 10
The plug insert, item 3, is removed from the pin
bushing, item 11, after the fastening screws,
item 10, have been unscrewed. Thereafter, the
plug insert can be connected to the connec-
tions of the plug pins, see fig. 5, page 10.
Attention: When the fastening screws, item
10, get lost, they will have to be replaced by
similar screws or to be ordered directly from
the manufacturer.
Pos 10 = Type Size 4 = KTG 40 x 24/14,
Pos. 5 = Type Size 5 = KTG 50 x 50/25.
Assembly is made in inverse order, after the
cable has been connected.
The connectible min. and max. conductor
cross-sections as well as the required minimum
cross-section for the current loading shall be
observed (see technical data). All screws and/or
nuts of the supply terminals, also of those
remaining vacant, shall be tightened down.
The conductors shall be connected with special
care in order to maintain the explosion category.
The supply terminals are designed for the
connection of copper conductors. 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).
Attention: The cable lugs should be crimped
onto the cable in a workmanlike manner.
It is to be ensured that the required min. air
gaps are kept (at 690V >12mm).
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 page 3, 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. In case of sealing inserts
that are cut out, it shall be ensured that the
insert is properly adapted to the cable diameter.
Care has to be taken that, when fitting the
cable entries, sealing inserts appropriate to the
cable diameter are used.
