When combining Ex-e/Ex-i it is essential to
maintain the separation, air and creepage
distances. The Ex-i circuit wires are to be laid
separately from the Ex-e circuit wires
1 (see e.g. EN/IEC 60079-11).
The connection wires of the Ex-i circuits are
2
to be marked (e.g. by colour, light blue).
3 When apparatus is open, it is necessary to
ensure (disconnect voltage supply) that no
4
voltage is carried over into the connected
intrinsically safe circuits.
5
The installation instructions for intrinsically safe
6
electrical apparatus shall be observed.
It is necessary to ensure that the permissible
7
external capacitance and inductance of the
8 special intrinsically safe circuits are not
exceeded.

In the case of building up the electrical
equipment in the "protective insulation" version,
appropriate sticker (
can be requested by the manufacturer.

If the inserted terminal rail is not equipped
completely with line-up terminals, the terminal

rail must be included in the equipotential earth
connection also.

6.3 Cable entries (KLE)/
Blanking plugs
8
Generally, only certified cable entries and
blanking plugs may be used. Flexible cables
13
are to be used with trumpet-shaped cable
glands or other suitable entries with
additional pull-relief.
Intrinsically safe circuits (Ex-i) are to be
connected through the coloured (light blue)
cable entries.
The mounting directives applicable to the
fitted cable entries are to be observed.
When using cable entries with a lower IP -
protection than that which applies to the
device (see technical data, page 7), the IP -
protection of the whole device will be
reduced.
In order to establish the minimum protection
category, unused holes have to be closed with
a certified blanking plug.
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 out, it will
have to be ensured that the insert is properly
adapted to the cable diameter.
In order to ensure the required minimum
protection category, the cable glands shall be
tightened down.
Overtightening might impair the protection
category.

Attention: When tightening the cap nut of
the (type ADL/ADE) metal cable entry, the
screwing is to be protected against twisting
by means of a suitable tool.
All vacant metric COOPER CROUSE-HINDS /
EATON cable entries shall be closed with the
certified blanking plug for metric cable entries.

Mounting: see fig. 9 and fig. 10
Unscrew the two fixing screws Item 4, and the
three fixing screws item 12 of the upper part
item 10, and remove the upper part.
Loosen the clamps item 14, of the strain-relief.
The cable sleeves item 13, have to be cut to
suit the cable diameter.
After fitting the cable, the cable sleeve item 13,
is to be sealed by means of the respective
clamp ring item 8.
