5 Use/Properties
The installation switches are designed for
switching on and off light circuits in hazardous
areas up to 16 A (see technical data). The
temperature class, explosion group and
permissible ambient temperature, see
technical data.
The installation switches can also be used in a
„normal industrial area".
The switch rocker is provided with a
luminescent label in acc. with § 7 of the
Workshop regulations and free from any
radioactive additives.
The data as per point 3 and 4 shall be
B
taken into account with the use.
Applications other than described are not per-
mitted without CEAG's prior written consent.
For the operation, the instructions stated in
section 7 of the operating instructions shall
be observed.
The user alone is responsible for the
appropriate use of this installation switch
in consideration of the basic conditions
existing at the plant (see technical data).
6 Installation
For the mounting and operation, the
respective national regulations (e. g.
Betr.Si.V., equipment safety law for Germany)
as well as the general rules of engineering
shall be observed.
The improper installation and operation of
safety switches may result in the
invalidation of the guarantee.

Mounting

The installation switches can be mounted
without opening their enclosure.
In case the switches are mounted directly
onto the wall, they may rest evenly only at the
respective fastening points. The chosen screw
shall match the fastening hole (see dimensio-
nal drawing) and it must not damage the hole
(e. g. use of a washer). The device shall be
fastened diagonally with at least 2 screws.
If the screws are overtightened, the
apparatus can be damaged.
When the installation switch is mounted with
the cable entries on bottom side, the switch
insert and the enclosure cover must be turned
through 180° (see fig.2).
The installation switch is suitable for fixing
onto CEAG apparatus holders size 1 by
means of self-cutting screws (see fig. 1).
The respective mounting instructions shall
be observed.
6.2 Opening the device/
Electrical connection
The electrical connection of the device may
only be carried out by skilled staff.
Before opening the apparatus, ensure that
it has been isolated from the voltage
supply, or take appropriate protective
meassures.
Taking into account the respective regulations,
the properly bared conductors of the cables
shall be connected.
The insulation of the conductors shall
reach up to the terminal. The conductor
itself shall not be damaged.
If the installation switch is mounted with the
cable entries on bottom, point 6.1 and fig. 2
will have to be observed.
After dismantling the switch base in order to
facilitate the introduction of cables, such
switch base will have to be properly fitted in
again prior to the electrical connection.
The connectible min. and max. conductor
cross-sections will have to be observed (see
technical data).
All screws and/or nuts of the supply terminals,
also of those remaining vacant, shall be
tightened down.
Excessive tightening may affect or damage
the connection.
The conductors shall be connected with
special care in order to maintain the
explosion category.
The supply terminals are designed for the
connection of copper conductors.
If multi- or fine-wire connecting cables are
used, the wire ends will have to be handled in
acc. with the applicable national and interna-
tional rules (e. g. use of ferrules).
