Safety information

It is essential that this manual, and the safety information in particular, is read, thoroughly un-
derstood and observed before setting the 3RG7256-3NQ00-PF distance sensor into operation.
The device may only be connected, mounted and adjusted by qualified personnel.
Interventions and alterations to the device are not permissible!
The 3RG7256-3NQ00-PF sensor is not a safety component as described by EU machine direc-
tives and must never be used in applications where human safety is at risk.
The device complies with laser protection class 2 according to DIN EN 60825/1, status november
2001. The technical requirements comply with EN 60947-5-2, 2000 edition.
Never look into the path of the laser. Do not suppress the reflex to close the eyelids.
Gazing into the beam path for longer periods can damage the retina of the eye.
When mounting the sensor, ensure if possible that the beam path is sealed off at the end. The
laser must not be directed at people (head height). When aligning the sensor, ensure that there
are no reflections on reflective surfaces.
Should the safety label on the sensor be partly covered due to its installation position, other
safety labels are to be positioned on visible parts of the sensor. When applying the new safety
label, make sure that you cannot look into the laser beam whilst reading it.
