auxiliary contact. In relation to the main
contacts, this auxiliary contact is lagging while
making and leading while breaking.
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 EN/IEC 60 947-3.
The „EMERGENCY-STOP" version conforms
to the requirements of EN/IEC 60 204-1.
To prevent unauthorized switching, the
switches can be locked in the „OFF" position
by means of 3 padlocks, see Fig. 1, (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.
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 control
switches with regard 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
Before mounting the safety switch, the cover
has to be removed from the enclosure base.
For this, the switch has to be set to the „ON"
position.
When the safety switches 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 drawings, page 6) and shall not
damage the hole (e.g. use of a washer).
The apparatus shall be fixed diagonally with a
minimum of 2 screws.
If the screws are overtightened, the
apparatus may be damaged.
The safety switches GHG 261 are suited for
mounting on CEAG apparatus holders size 1
by means of self-cutting screws (see Fig. 2).
See the respective mounting instructions.
6.2
Opening apparatus /
Electrical connection
The electrical connection of the apparatus
may only be carried out by specialists.
Before opening the apparatus, ensure
that it has been isolated from the voltage
supply or to take suitable protective
measures.
Before opening, set the switch to the „ON"
position.
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 technical data, page 6).
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 standard terminals are designed for the
direct connection of conductors with copper
wires.
If multi- or fine-wire connection 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 connection terminals is
shown in the wiring diagrams on the switch
base and in Fig. 3 on page 7 of the operating
instructions.
To ensure that the safety switch closes
correctly, switching at the switch shaft of the
switch insert is not permitted when the
apparatus is open.
If, to facilitate the feeding of conductors into
the enclosure, the switch insert is removed
from the enclosure base, it shall be put back
correctly before the electrical connection is
made.
