Safety instructions
The operations must be carried
out by electrical suitably trained
in hazardous area with
knowledge of increased safty
explosion protection IEC/EN 60079-14.
The manual motor starters are not
suitable for zone 0 and Zone 20
hazardous areas.
The temperature class and type of
protection stated on the apparatus shall
be observed.
The requirements of the IEC/EN 61241-0
and -1 regarding excessive dust deposits
and temperature to be considered from
the user.
Modifications or changes to the manual
motor starters are not permitted.
They shall be used for their intended
purpose and shall be in a perfect and
clean state.
Only original COOPER Crouse-Hinds
parts may be used as replacements and
for repairs.
Repairs that affect the explosion
protection may only be carried out by
COOPER Crouse-Hinds or by a qualified
electrician in compliance with the
respective national regulations.
Prior to being put into operation, the
manual motor starters shall be checked in
accordance with the instructions as per
section 6.
Before initial operation, any foreign
matter shall be removed from the
apparatus.

Warning:
Observe the terminal cross sections of
the manual motor starters in table 1.6,
page 9.
The national safety rules and regulations
for the prevention of accidents, as well as
the safety instructions included in these
operating instructions, that, like this text, are
set in italics, shall be observed!

Conformity with standards
The manual motor starters are conform to the
standards specified in the EC-Declaration of
conformity, enclosed separately.
It has been designed, manufactured and
tested according to the state of the art and to
DIN EN ISO 9001.
94/9 EC: Equipment and protective systems
intended for use in potentially explosive
atmospheres.
The control units fulfil further requirements,
such as the EC directive on electromagnetic
compatibility (2004/108/EC).
4
Field of application
The manual motor starters are suitable for use
in zone 1, 2 and 21, 22 hazardous areas acc.
to IEC/EN 60079-10-1 and -2.
The enclosure materials employed, including
the exterior metal parts, are made of high-
quality materials which ensure a corrosion
protection and resistance to chemical
substances corresponding to the
requirements in a "normal industrial
atmosphere":
- glass-fibre reinforced polyester
- impact resistant polyamide
- special steel AISI 316 L
In case of use in an extremely aggresive
atmosphere, please refer to manufacturer.

Application / Properties
5
The manual motor starters are used for the
protection of explosion-protected motors,
regardless of the explosion category, against
overload and phase failure.
The temperature class, explosion group, tripping
characteristic and permissible ambient
temperature can be found in the technical data.
Due to the AC 3 motor switching capacity of
the manual motor starter, a safe and reliable
isolation (switching) is also possible during
operation.
The use of an undervoltage trip prevents the
self-starting of the motor. In addition, the
undervoltage trip can be used for disconnecting
emergency circuits.
The auxiliary contact (optional) is mainly used
for signalling the operating state of the manual
motor starter.
To safeguard the manual motor starter against
unauthorized use, it can be locked in the OFF
position 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.
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
motor starters with regard to the basic
requirements of these instructions (see
technical data) lies with the operator.
