The auxiliary contact (optional) is mainly used for
signalling the operating state of the manual motor
starter.
To safeguard the manual motor starter against un-
authorized use, it can be locked in the OFF posi-
tion by means of 3 padlocking facilities (shackle
diameter of padlocks up to 5 mm).
The data according to sections 3 and 4 shall
be taken into account during use.
Applications other than those described are
not permissible without a written declaration
of consent from Messrs. COOPER Crouse-Hinds.
A
During operation the instructions stated in
section 7 of the operating instructions shall be
observed.
The sole responsibility with respect to the
suitability and proper use of the manual mo-
tor starters with regard to the basic require-

Installation

The relevant national regulations and the
generally recognized rules of engineering apply
A
for the installation and operation.
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 appara-
tus 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 be
connected with due regard to the respective
regulations.
To maintain the explosion protection, conduc-
tors 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.
Excessive tightening may affect or damage
the connection.
The terminals are designed for the direct connec-
tion 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.
