Installation
The relevant national regulations and the
generally recognized rules of engineering
apply for the installation and operation.
A
The improper installation and operation of
manual motor starters may result in the
invalidation of the guarantee.
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).
A
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.
6.2
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
A
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).
All screws and/or nuts of connection
terminals, including those not in use, shall be
tightened down securely.
A
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
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.
