Mounting

The wall sockets can be mounted without
opening the enclosure.
When wall sockets are mounted directly onto
the wall, they shall 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 fastened
diagonally with at least 2 screws.
The wall-mounting shall be mounted in such
a way that the plug opening does not face
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).
Before opening the apparatus, ensure that it
has been isolated from the voltage supply,
or take appropriate protective measures.
Taking into account the respective regulations,
the properly bared conductors of the cables
shall be connected.
7
The insulation of the conductors shall reach
up to the terminal. The conductor itself shall
not be damaged.

Figs. 3 + 4, page 10
Undo the fixing screws, Item 5, to remove the
plug insert, item 3, from the plug sleeve, Item
11. The plug insert can then be connected to the
plug pin connections (see fig. 5, page 10).
Warning:
If any fixing screws, item 5, are lost, they
shall be replaced by screws of the same type
or ordered directly from the manufacturer.
Type: Size 5 = KTG 50x50/25
After connecting the cable, proceed in the
6
reverse order to reassemble plug.
The connectable min. and max. conductor
cross-sections as well as the required
5
minimum cross section for the current load
shall be observed (see technical data).
All screws and/or nuts of the supply
7
terminals, including the unused ones, 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
9
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).
Warning: The cable lugs shall 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 7 , 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.
Care has to be taken that, when fitting the
cable entries, sealing inserts appropriate to the
cable diameter are used.
In case of sealing inserts that are cut to size, it
shall be ensured that the insert is properly
adapted to the cable diameter.
In order to ensure the required minimum
protection category, the cable glands are to be
tightened down.
Overtightening might impair the protection
category.
All unused metric COOPER CROUSE-HINDS
cable entries shall be closed with the certified
blanking plug for metric cable entries.
Attention: Metal flanges, metal plates and
metal cable glands shall be included in the
equipotential earth connection.
6.3.2 Plug
In general, only the sealing inserts, fig. 6,
item 12, fitted in the plug may be used.
When mounting the cable, ensure that the
sealing inserts match the cable diameter used.
After connecting the cable, screw down the cap
nut , fig. 6, item 4, by hand until it seals. Then
tighten down the screws, fig. 6, item 5, of the
pull-relief, fig. 6, item 6.
Warning! Overtightening might impair the
pull-relief or damage the connection cable.
