Explosion protected plug and socket system 32A, GHG 517
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
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.
6.1
Mounting
6
The wall sockets can be mounted without
opening their enclosure.
In case the wall sockets are mounted directly
5
onto the wall, they may rest evenly only at the
respective fastening points. The chosen screw
shall match the fastening hole (see dimensio-
nal 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.
Item 3
The wall sockets can be clipped onto the
COOPER CROUSE-HINDS / CEAG mounting
plate size 5. 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.

Fastening point A
wall socket 32A
The wall sockets, flange sockets and
couplers shall be mounted so that the plug
hole does not points upwards (fig. 2).
6.2
Opening the device/
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.
Taking into account the respective regulations,
the properly bared conductors of the cables
shall be connected.
When using 10mm² cables for connection it is
reccomended to cut back the outer sheath for
approx. 200mm and remore the required
length of insulation on each core before
entering cable into the socketoutlet.
The plug insert (item 2, fig. 4) is removed from
the pin bushing (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 view 1, fig. 4).
Attention: When the fastening screws (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. The connectible min. and
max. conductor cross-sections 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).
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.
