Explosion protected plug and socket system 32 A, GHG 517
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 enclo-
sure, 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).
6.1

Mounting

The wall sockets can be mounted without
opening their enclosure.
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
6
fastened diagonally with at least 2 screws.
The wall sockets can be clipped onto the
COOPER CROUSE-HINDS / CEAG mounting
5
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.
Item 3
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 (IEC/EN 60079-14).

wall socket 32A
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
recommended 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 trum-
pet-shaped cable glands or other suitable
entries with additional pull-relief.
