Safety instructions

This inductive sensor is not permitted for use in
applications where personal safety depends on
proper function of the device (not a safety
component according to the EU Machine
Directive). Read this manual carefully before
commissioning.
Sensors may only be connected when the
power is off.
Non-permitted electrostatic discharges on
housing parts can be prevented by grounding
the metal parts.
No changes or modifications may be made to
devices that are intended for use in explosion
hazard areas. Both for proper operation as well
as for error states, certain residual risks remain
despite correct explosion protection; these risks
can cause danger to people and the system.
If safe operation can no longer be guaranteed,
the device must be disconnected from its power
source and secured against further use.
