Explosion-protected plugs and sockets 16 A, GHG 511
The plug can be pushed into the socket and
pulled out of it only whilst the socket ist
switched off.
then turned through approx. 45° to the right.
Thereby the plug is locked in the socket
(see fig. 2 #2).
For switching off and pulling the plug, proceed
in inverse order.
After separating the plug from the socket, the
latter shall be closed with the hinged cover
and secured with the bayonet ring.
The plug can be pushed into the socket
and pulled out of it only whilst the socket is
switched off.
In order to ensure the socket's type of protec-
tion acc. to the type label also with the plug
being inserted, the bayonet ring of the plug
(fig. 3, item 3) is turned to its stop onto the
socket.
5 Installation
For the mounting and operation, the respec-
tive national regulations as well as the general
rules of engineering will have to be observed.
5.1 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 wall mounting bracket could be mounted
as shown in Fig. 1. 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 with all 4 screws.
The wall sockets shall be mounted so that the
plug hole does not points upwards (fig. 2).
5.2 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.
Assembly is made in inverse order, after the
cable has been connected.
The connectible min. and max. conductor
cross­sections as well as the required
minimum cross­section 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.
In order to ensure the required minimum
protection category, the cable glands are to be
tightened down.
Overtightening might impair the protection
category.
All vacant metric COOPER CROUSE-HINDS /
GBCEAG cable entries shall be closed with
the certified blanking plug for metric cable
entries.
Flexible cables shall be used with trumpet­
shaped cable glands or other suitable
entries with additional pull­relief.
When using cable entries with a lower IP pro-
tection than that which applies to the device,
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 mini-
mum 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.
In order to ensure the required minimum
protection category, the cable glands are to be
tightened down.
Overtightening might impair the protection
category.
All vacant metric COOPER CROUSE-HINDS /
CEAG cable entries shall be closed with the
certified blanking plug for metric cable entries.
