Safety instructions
The D22 519 plugs and sockets are
not suitable for Zones 0, 1, 2 and
Zone 20, 21 hazardous areas.
The temperature class and
explosion group marked on the apparatus
shall be observed.
To ensure adherence to the temperature
class stated on the type label of the
apparatus, the permissible ambient
temperature, the rated terminal cross section
and the self-heating of the apparatus, that is
mainly due to the power dissipation, shall be
taken into account (test criterion for the self-
heating is an overload of 10%).
The requirements of the EN 61241-0 and -1
regarding excessive dust deposits and
temperature to be considered from the
user.
Before opening the apparatus, ensure that
it has been isolated from the voltage
supply, or take appropriate protective
measures.
Modifications or changes to the plugs and
sockets are not permitted.
They shall be used for their intended
purpose and in a perfect and clean
condition.
Only original COOPER CROUSE-HINDS
parts may be used as replacements and for
repairs.
Repairs that affect the explosion
protection, may only be carried out by
COOPER CROUSE-HINDS or a qualified
electrician in compliance with the
respective national regulations.
Prior to being put into operation, the plug
and socket shall be checked in accordance
with the instructions in section 6.
The sockets may only be used with the
associated COOPER CROUSE-HINDS plugs
in an undamaged condition.
The plugs type D22 519 .. shall only be used
in wall sockets of the series D22 519 ... ,
GHG 519 ... and GHG 525 ... .
The plugs may also be used in any Series 1
IEC industrial socket outlets.
The socket insert and the actuating switch
are mechanically interlocked in such a way
that operation (switching on) is only
possible when the plug is inserted.
Before initial operation, any foreign matter
shall be removed from the the plugs and
sockets.
The national safety rules and regulations
for the prevention of accidents, as well as
the safety instructions included in these
operating instructions, that, like this text,
are set in italics, shall be observed!

Conformity with standards
The apparat is conform to the standards
specified in the EC-Declaration of conformity.
It has been designed, manufactured and
tested according to the state of the art and to
DIN EN ISO 9001.
94/9 EC: Equipment and protective systems
intended for use in potentially explosive
atmospheres.
The plugs and sockets also fulfil further
requirements, such as those of the directive on
electromagnetic compatibility (2004/108/EC).
4
Field of application
The plugs and sockets D22 519 are suitable
for use in Zone 22 dust hazardous areas acc.
to EN 61241-0!
The enclosure materials employed, including
the exterior metal parts, are made of high-
quality materials which ensure a corrosion
protection and resistance to chemical
substances corresponding to the requirements
in a "normal industrial atmosphere":
- impact resistant polyamide
- glass-fibre reinforced polyester
- special steel AISI 316 L
In case of use in an extremely aggresive
atmosphere, please refer to manufacturer.

Use/Properties
The D22 519 plugs and sockets are used for
the power supply of local controls with varying
locations, as well as of electrical installations,
mobile machinery and driving gear in dust
hazardous areas. The plugs and sockets can
also be used in a „normal industrial area".
The low-voltage plugs and sockets D22 519
are fitted with a load break switch and can be
used up to max. 125A (see technical data).
The plugs and sockets can generally be used
for the voltage range laid down in IEC 309
(e.g. U
400V that corresponds to the voltage
N
range 380-415V).
The apparatus connected to the plug shall
be suitable for the applied mains voltage.
The plug can only be inserted or withdrawn
when no voltage is applied.
The socket can only be switched on if the plug
is fully inserted.
In order to guarantee the type of protection
stated on the type label, also when the plug
has been inserted, the bayonet ring of the
plug, page 9, Fig. 2. Item 2, has to be turned
until it reaches the stop on the socket.
To switch off and withdraw the plug, proceed
in the reverse order.
After withdrawing the plug from the socket,
seal the socket with the hinged cover and
secure it with the bayonet ring, page 9, Figs. 1
and 2, Item 9.
The data according to sections 3 and 4
shall be taken into account during use.
Applications other than those described are
not permissible without a written
declaration of consent from Messrs.
COOPER CROUSE-HINDS.
During operation the instructions given in
section 7 of the operating instructions shall
be observed.
From time to time it is necessary to check
the functioning of the interlock that acts as
a protection against incorrect use, e.g. of
industrial plugs in Zone 1. See section 7,
Maintenance / Servicing.
When used in open air installations, the
plugs must be kept with the plug opening
(pin end) facing downwards or be sealed
with protective plug caps that are available
as an optional extra (see main catalogue).
The sole responsibility with respect to the
suitability and proper use of the plugs and
sockets with regard to the basic
requirements of these instructions (see
technical data) lies with the operator.
After a short in the circuit, the functioning
of the plug and socket shall be checked.
As, due to the flameproof encapsulation, it
is not possible to check the switch
contacts, the complete switch insert has to
be replaced after repeated short circuits.
6
Installation
The relevant national regulations(e.g. Betr.Si.V,
the equipment safety law for Germany) and
the generally recognized rules of engineering
apply for the installation and operation.
