Cooper Crouse-Hinds GmbH
Explosion-protected safety switches for variable
frequency drives, 20A - 180A
Specially marked auxiliary contacts of the
safety switches can be used in "intrinsically
safe circuits".
The electrical limiting values that are
decisive for the intrinsic safety shall be
observed.
Versions with gold-tipped auxiliary contacts
are suited for switching extra-low voltage
circuits. Special attention shall be paid to the
maximum current load (see technical data,
page 10). The contact chamber of the gold-
tipped version is marked with the letter "G" or
colour-coded.
Due to the mechanical design of the safety
switch, compulsory opening of the contacts is
possible.
The safety switches fulfil the isolating
properties according to DIN EN 60 947-3,
(IEC 947-3).
To prevent unauthorized switching, the switches
can be locked in the „OFF" position by means
of 3 padlocks, see Fig. 4, page 11 (shackle
diameter of the padlocks up to 4 - 6 mm).
A built-in locking device prevents the opening
of the enclosure in the „OFF" position.
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. CCH
/ CEAG.

The instructions stated in section 7 of the
operating instructions shall be observed
during operation.
The sole responsibility with respect to the
suitability and proper use of the control
switches according to the basic
requirements of these instructions (see
technical data) lies with the operator.

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
safety switches may result in the
invalidation of the guarantee.
6.1
Mounting
The safety switches can be mounted without
opening the enclosure.
When mounted directly onto the wall, the
safety switches shall rest evenly only at the
fastening points provided for them.
The chosen screw shall match the fastening
hole (see dimensional drawing) and shall not
damage the hole (e.g. use of a washer).
