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.
The correctly stripped wires of the cable
shall be connected according to the relevant
regulations.
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
7
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
9
reverse order to reassemble plug.
The connectible min. and max. conductor
cross-sections as well as the required
minimum cross section for the current load
shall be observed (see technical data).
All screws and/or nuts of the supply
terminals, including the unused ones, shall
be tightened down.
The conductors shall be connected with
special care in order to maintain the type of
protection.
6
The supply terminals are designed for the
connection of copper conductors. If multi- or
fine-wire connecting cables are used, the wire
5
ends will have to be handled in acc. with the
applicable national and international rules
(e. g. use of sleeves for strands).
7
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 and suitable 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 pro-
tection 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 mini-
mum protection category. In case of sealing
inserts that are cut to size, 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 unused metric CEAG 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.
