4 Mounting
DANGER
Mount
ing must only be done by authorized and qualified personnel!
Mounting must be done by qualified safety personnel in compliance with the following
notes and specifications.
Follow the following mounting instructions. Otherwise the guarantee becomes invalid.
NOTE
T
his device is part of a protective device for safeguarding a machine. A risk analysis
should be done before mounting to determine if the specifications of this device are
suitable for all foreseeable operating and environmental parameters of the machine in
which is installed.
Ambient conditions
Mount t
he sensor and actuator on a non-ferrous surface and at a distance from metal
parts if possible in order to avoid influencing the sensing range. If this is not possible,
the influence on assured switch-on distance Sao and assured switch-off distance SAR
must be checked.
Steps for mounting the device
1. Select the mounting position for the safety switch so that the sensor and actuator
for are easily accessible monitoring and exchange work and are protected from
damage.
2. Make sure that dangerous states are excluded when the protective device is
opened, even if the actuator has not yet reached the assured switch-off distance.
3. Observe ISO 14119 when mounting the safety switch and actuator.
4. Observe EN ISO 14119 for reducing the possibilities for circumvention of an inter‐
locking device.
5. Mount the actuator on the movable part of the protective device.
6. Mount the sensor on the fixed part of the protective device.
7. Align the sensor and actuator so that their front sides face each other at a switch-
off distance of 15 mm (for M18 actuator) or 25 mm (for M30 actuator) or closer
when the protective device is closed (see figure 1, page 11, see figure 2,
page 11).
