DANGER
Live parts. Explosive atmosphere. Explosion haz­
ard! Risk of burns! Ignoring this message will lead
to serious injuries or death. Connecting and discon-
necting only to be performed by qualified and au-
thorised personnel. Connecting and disconnecting
only in non-explosive atmospheres.
The safety sensor, as well as the actuator should be mounted on an
even surface and oppositely according to the marks on sensor and
magnet. The electrical connection may only be carried out by author-
ised personnel. They must take care that the accessibilty of actuators
or spare actuators because of the danger of manipulation is prevented.
Please ensure that, even in case of failure, the safety sensor cannot be
moved from its position. In addition, the actuator must be positioned
and protected in such a way that damage by predictable external influ-
ence is avoided. When mounting actuator and sensor please observe
the requirements of EN ISO 14119, especially paragraph 7 »Design to
decrease manipulation and bypass of interlocking devices.«! For pro-
tection against manipulation use oneway safety screws, Torx with pin,
riveting, etc. Safety sensor and actuator should not be fixed on ferro-
magnetic material, this leads to strong changes of the switching dis-
tances. Do not install the safety sensor and the actuator in strong
magnetic fields. The presence of ferromagnetic chips may reduce sen-
sitivity. Do not expose the components to extreme vibrations and
shocks. A mounting distance of min. 50 mm between two systems
must be observed. Depending on the electrical load the magnetic sen­
sor must be protected from voltage and current peaks by suitable
protection circuits. It is required to distinguish between ohmic, induc­
tive and capacitive load. The enclosure is equipped with a terminal for
a protective conductor for max. 4 mm² wire. Please also observe the
instructions in the standards EN ISO 12100 and EN ISO 14120.

Application / Operation

=
DANGER
High operation temperatures, overloaded contacts.
Explosion hazard! Risk of burns! Ignoring this
message will lead to serious injuries or death. For
short-circuit protection observe correct fuse size.
- Use device only within the permitted electrical load limits (see tech-
nical data).
- Use device only within the permitted ambient temperature range (see
product label and technical data).
Cleaning
- Use a damp cloth to clean devices in explosive areas. This prevents
electrostatic charge.
- In case of damp cleaning: use water or mild, non-scratching, non-
chafing cleaners.
- Do not use aggressive cleaners or solvents.

Live parts. Electric shock hazard! Ignoring this
message will lead to serious injuries or death. Do
not repair defective or damaged devices. Replace
them.

Explosive atmosphere. Risk of burns! Ignoring this
message will lead to serious injuries or death. Do
not rebuild or modify the device in any way.
With careful mounting as described above, only minor maintenance is
necessary. We recommend a routine maintenance as follows:
1. Check the switching function.
2. Check for tight installation of the actuator and the switch.
3. Verification of the alignment of sensor and actuator.
4. Remove dirt and swarfs.
5. Check enclosure for damage.
Special Conditions / »X« Marking
A fuse according to the switching current of the sensor to IEC 60127-1-
2 must be connected to each safety sensor. The fuse can be installed
inside the supply device or must be connected separately. The fuse op-
erating voltage must be as high as or higher than the maximum
switching voltage of the Ex safety sensor. The safety-technological
maximum values of the switching currents must limited to 125 mA and
20 mA with the LED variant by additional external measurements. The
switch-off capacity of the fuse must be as high as or higher than the
maximum short-circuit current at the place of installation (normally
1500 A).
- Lay the connection cable securely to protect it from mechanical dam-
age.
- If the connection is carried out within an explosive environment, con-
nect the cable inside an enclosure which meets the requirements of
an approved ignition protection type per EN 60079-0.
- The maximum short circuit current I k of the supply source may not
exceed the I k value given on the product label.
Notices
The specified switching distances refer to face-to-face mounted safety
sensors and actuators. Different arrangements are possible, may lead
to different switching distances, however. The maximum possible off-
set between actuator and sensor can be found in the diagram »Axial
offset«. It must be observed that protective guards like doors, grids,
etc. change their position / direction in due time because of mechani-
cal wear. The switch-off distance (s ar ) between safety sensor and ac-
tuator must be observed (opening of the safety guard). The correct
