6.1 Transport / Storage
before installation
The delivery is to be tested for completeness
and integrity. If the delivery is incomplete, then
an inventory must take place immediately with
the transport company.
Any damage must be documented.
For storage, the explosion-protected main-,
load- and safety switches must be placed on a
clean dry flat surface. This situation should not
be altered. The distribution boards must be
protected from adverse weather conditions.
6.2 Montage
Only skilled electricians and instructed
personnel in accordance with national
legislation, including the relevant standards and,
where applicable, in acc. with IEC/EN 60079-14
on electrical apparatus for explosive atmos-
pheres should mount and install the explo-
sion-protected main-, load- and safety switches.
The explosion-protected main-, load- and safety
switches. can be mounted without opening the
enclosure.
The explosion-protected main-, load- and safety
switches must not be left near heat sources.
When mounting the explosion-protected main- ,
load- and safety switches directly onto the wall,
they shall rest evenly only on the fastening
points provided for them.
Use all attachment points to mount the
enclosure.
The chosen screw shall match the fastening
hole (see dimensional drawing) and it must not
damage the hole (e. g. use of a washer).
If the screws are overtightened, the apparatus
may be damaged.
The switches 25 A and 40 A with platic
enclosure are suitable for fastening onto
COOPER CROUSE-HINDS / CEAG apparatus
holders size 3 by means of self-cutting screws
(see fig. 2).
Observe the relevant operating instruction.
Observe the respective national regulations as
well as the general rules of engineering which
apply to the installation and operation of
electrical apparatus!
6.3 Opening explosion-protected
main-,load- and safety switches
Before opening the explosion-protected
main-,load- and safety switches, ensure that it
has been isolated from the voltage supply, or
take appropriate protective meassures.
Before opening , set the switch to the „ON"
position.

6.4 Cable entries (KLE);
blanking plugs
The threaded holes for cable and wires are
closed with an adhesive tape for transport.
Remove this tape residue-free.
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.
When using cable entries with a degree of
protection that is lower than the IP protection of
the apparatus (see Technical Data), the degree
of IP protection for the complete unit is
reduced.
In order to ensure the minimum degree of
protection, any unused entry holes shall be seal
with certified blanking plugs.
When fitting cable entries, it is necessary to
ensure that the sealing inserts used are suitable
for the cable diameter.
In the case of sealing inserts that are cut to
size, it is necessary to ensure that the insert In
order to ensure the required minimum
protection category, the cable glands are to be
tightened down.
If fittings are overtightened, the protection class
may be compromised.
Attention: When tightening the cap nut of the
type ADE 1F metal cable entry, the screwing is
to be protected against twisting by means of a
suitable tool.
In order to establish the minimum protection
category, unused holes have to be closed with
a certified blanking plug.
6.4.1
„t" Staub (Zone 22)
It is to ensure that by, for example, use of
sufficiently dense cable glands, plugs and
wires, the required "t" characteristics to
IEC/EN 60079-31 be remain.
