Explosion-protected distributions GHG 619
Observe the datas and notes regarding the bus
bar system GHG758 in the operating instruction
GHG 750 7002 P0001, enclosed separately.If
connection terminals up to 240 mm² (bolt
terminals) are built into the terminal boxes,
these terminals shall be wired as shown in
Fig. 10, page 47 (max. 2x 240 mm²).
5
In the case of mixed Ex-e / Ex-i installations,
the required minimum clearances shall be
maintained (see, for example,
IEC/EN 60079-11).
The instructions for the installation of
intrinsically safe electrical apparatus shall be
observed.
It is necessary to ensure that the permissible
external capacitance and inductance for the
specific intrinsically safe circuit are not
exceeded.
7
When the apparatus is open, it is necessary
to ensure (isolate voltage) that there is no
voltage transmission to the 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
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
13
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.
EATON's Crouse-Hinds Business
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.
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
securely 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 26),
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.
Metal cable glands have to screw in with the
relevant test torque in cap 11.
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.
