Explosion-protecded distributions GHG 619
It is necessary to ensure that the
permissible external capacitance and
inductance for the specific intrinsically
safe circuit are not exceeded.
When the apparatus is open, it is
necessary to ensure (isolate voltage) that
there is no voltage transmission to the
5
connected intrinsically safe circuits.
The circuit diagram for the built-in
components is either shown on the
components, enclosed with the switch unit, or
shown in the operating instructions. In the
case of wired control units, the connection
diagram included with the apparatus is to be
observed.
When using multi- or fine-wire connection
cables, the wire ends shall be treated in
accordance with the valid national and
international regulations (e.g. use of cable end
7
sleeves).
To ensure that the distribution enclosure
closes properly and to avoid damage,
switching at the switch shafts of the switch
inserts is prohibited when the apparatus is
open or the cover is only replaced loosely.
If a flameproof component is disassembled,
before it is connected to the electric power
supply, it is necessary to ensure that the
components are put back into the distribution
enclosure correctly.
For actuating the flameproof protective
components (circuit breakers / ELCBs
RCDs), the actuating flap may also be
opened while the circuit is live.
Overtightening can damage the enclosure
or impair the sealing effect.
6.3 Cable entries (KLE);
blanking plugs
Generally only certified cable entries and
blanking plugs may be used.
Trumpet-shaped cable glands or other
suitable entries with additional pull relief
shall be used for flexible cables .
The relevant mounting directives for the
built-in cables entries shall be observed.

See Figs. 8 and 9 for how to
assemble double cable end boxes:
Undo the 2 fixing screws, Item 4, and the 3
fixing screws, Item 12, of the top, Item 10,
and remove the top.
13
Loosen the semicircular clamping pieces,
Item 14, of the strain relief. Adapt the cable
sleeves, Item 13, to suit the cable diameter
and pull over the connection cable.
Then screw the semicircular clamping
pieces, Item 14, of the strain relief securely
onto the strain relief clamp again.
Once the cable has been fitted, secure the
cable sleeve with the respective cable clamp,
Item 8.
Finally, replace the top, Item 10, and fix se-
curely in position with the fixing screws, Items
4 and 12, and refit the strain relief, Item 14.
Seal the unused entry opening of the double
cable end box with a blanking plug, Item 5,
(Order No. GHG 740 1993 R0003).
Warning: To guarantee the IP degree of
protection, it is necessary to ensure that
the seal, Item 6, is fitted correctly.
When using cable entries with a degree of
protection that is lower than the IP protection
of the apparatus (see Technical Data, pages
18), the degree of IP protection for the
complete unit is reduced.
The colour-coded (light blue) cable entries
shall be used for leading-in the intrinsically
safe circuits.
In order to ensure the minimum degree of
protection, any unused entry holes shall be
sealed with certified blanking plugs.
When fitting cable entries, it is necessary to
ensure that the sealing inserts used are
suitable for the cable diameter.
When using apparatus or cable entries for
the connection to or into the apparatus, when
applicable, the relevant special conditions for
safe use given in the individual certificates
shall be considered.
In the case of sealing inserts that are cut to
size, it is necessary to ensure that the insert
is properly adapted to the cable diameter.
In order to ensure the required minimum
degree of protection, the cable entries shall
be tightened down securely.
Overtightening can impair the degree of
protection.
Warning: When tightening the cap nut of
the metal cable entry (e.g. type ADE/e), a
suitable tool shall be used to stop the
gland from twisting.
Any unused metric Cooper Crouse-Hinds /
CEAG cable entries shall be sealed with the
certified blanking plug for metric cable
entries.
