6.3 Cable entries (KLE);
blanking plugs
Generally, only certified cable entries and
blanking plugs may be used.
Flexible cables shall be used with trum-
pet-shaped cable glands or other suitable
entries with additional pull-relief.
When using cable entries with a degree of
protection that is lower than the IP protection of
the apparatus (see page 8), the degree of IP
protection for the complete unit is reduced.
The relevant mounting directives for cables
entries being used shall be observed
In order to ensure the minimum degree of
protection, any unused entry holes shall be
sealed with certified blanking plugs.
When fitting cable entries, care has to be taken
that the sealing inserts are suitable for the cable
diameter.
In the case of sealing inserts that are cut out, 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.
Any unused metric COOPER Crouse-Hinds cable
entries shall be sealed with the blanking plug
certified for these metric cable entries.

Manual motor starters up to 25 A, GHG 635
6.4 Plastic*and metalflange plates
If flange plates have to be dismantled, (e.g. to
drill entry holes), when replacing the plates, in
order to maintain the minimum degree of
protection, it is necessary to ensure that the
Earth plate
flange plate and the fixing clamp fit correctly.
PE conductors fed from outside shall be
connected to the PE terminal provided on the
flange.
In case an external earth connection is mounted
on the plastic enclosure, it should be connected
with a max. 25 mm² wire.
This earth connection is inserted through a M6
drill in the inner wall of the enclosure
(see fig. 10).
Warning: Metal flanges, metal plates and
metal glands shall be incorporated in the
potential equalization.

6.5 Closing apparatus /

Cover closure
Any foreign matter shall be removed from the
apparatus.
The setting screw on the switch insert for
setting the rated current shall be set to the rated
motor current.
The switch handle on the cover of the manual
motor starter shall be in the position it had when
the apparatus was opened.
When fitting the apparatus cover, care shall
be taken to ensure that the switch shaft of
the switch insert engages correctly in the
carrier hole of the switch handle.
To ensure the required minimum degree of
protection, the cover screws shall be tightened
down.
Overtightening may impair the degree of
protection.

6.6 Putting into operation

Before putting the apparatus into operation, the
tests specified in the individual national
regulations shall be performed.
In addition to this, before being put into
operation, the correct functioning of the
apparatus and installation of the apparatus shall
be checked in accordance with these operating
instructions and other applicable regulations.
The improper operation of manual motor
starters may result in the invalidation of the
guarantee.

Maintenance / Servicing

The valid national regulations for the
servicing / maintenance of electrical
apparatus for use in potentially explosive
atmospheres shall be observed
(IEC/EN 60079-17).
Prior to opening the enclosure, it is necessary
to ensure that the voltage supply has been
isolated or to take suitable protective
measures.
The necessary intervals between servicing
depend upon the specific application and shall be
stipulated by the operator according to the
respective operating conditions.
During servicing, above all, the parts on which
the explosion protection depend, (e.g. intactness
of the flameproof components, the enclosure,
the seals and cable entries), and the reset
function of the switch handle shall be checked.
If, in the course of servicing, it is ascertained,
that repairs are necessary, section 8 of these
operating instructions shall be observed.
8 Repairs / Overhaul /
Modification
Only original COOPER Crouse-Hinds parts shall
be used for carrying out repairs.
In the event of damage to the flameproof
encapsulation, replacement of these
components is mandatory. In case of doubt,
the respective apparatus shall be sent to
COOPER Crouse-Hinds for repair.
Repairs that affect the explosion protection
may only be carried out by COOPER Crouse-
Hinds or by a qualified electrician in compli-
ance with the respective national regulations
(IEC/EN 60079-19).
Apparatus modifications or design changes are
not permitted; excepted from this is the fitting of
additional cable entries within the scope of the
apparatus approvals.

Disposal / Recycling

The respective valid national regulations for
waste disposal shall be observed when
disposing of apparatus.
To facilitate recycling of individual parts, parts
made of moulded plastic shall bear the marking
for the type of plastic used.
The product range is subject to changes and
additions.
