6.2 Opening apparatus /
Electrical connection
Before opening the apparatus, it is
necessary to ensure that there is no voltage
or to take suitable protective measures.
The electrical connection of the may only
be carried out by specialists.
The properly bared conductors of cables shall
be connected with due regard to the
respective regulations.
To maintain the explosion protection,
conductors shall be connected with special
care.
The insulation shall reach up to the
terminal. The conductor itself shall not be
damaged.
The minimum and maximum conductor
cross sections that can be connected shall
be observed (see section 1.6, technical
data).
Manual motor starters up to 25A, GHG 635
6.1 Montage
The manual motor starter can be mounted
without opening the enclosure.
When the manual motor starters are mounted
directly onto the wall, they shall rest evenly
only on the fastening points provided for this
purpose.
The screw chosen shall fit the fixing hole (see
dimensional drawing) and shall not damage
the hole (e.g. use of a washer).
If the screws are overtightened, the
apparatus may be damaged.
The manual motor starters are suited for plug-
in mounting on COOPER Crouse-Hinds
apparatus holders, size 3, whereby they are
pushed into the guide groove from the top of
the apparatus holder. See the respective
mounting instructions.
6 Installation
The relevant national regulations(e.g. Elex V,
the equipment safety law for Germany) and
the generally recognized rules of engineering
apply for the installation and operation.
The improper installation and operation of
manual motor starters may result in the
invalidation of the guarantee.

All screws and/or nuts of connection
terminals, including those not in use, shall be
tightened down securely.
Excessive tightening may affect or damage
the connection.
The terminals are designed for the direct
connection of conductors with copper wires. If
multi- or fine-wire connecting cables are used,
the wire ends shall be handled according to
the applicable national and international
regulations (e.g. use of multicore cable ends).
The position of the terminals can be found in
the wiring diagram of the switch insert on
page 8, technical data.
To ensure a correct closing of the manual
motor starter, switching at the switch shaft of
the switch insert when the apparatus is open
is not permitted.
If, to facilitate the feeding of conductors into
the enclosure, the switch insert is snapped out
of the rail on the enclosure base by releasing
the catches (top or bottom on insert), it shall
be snapped back into position in the
enclosure base before the electrical
connection.
The end clamps on the DIN rail are used for
fixing the switch insert on the rail and shall
not be dismounted under any
circumstances.
The undervoltage trip is generally connected
to separate terminals(see wiring diagram on
page 8, technical data). Wiring of the
undervoltage trip according to the individual
application shall be carried out by the user.
6.3 Cable entries (KLE);
blanking plugs
Generally, only certified cable entries and
blanking plugs may be used.
Flexible cables shall be used with trumpet-
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
