WARNING
!
Before applying power to the Renishaw laser encoder
and for detailed installation instructions please refer to
the RLE laser encoder installation guide which is supplied
with the product.
LASER SAFETY
DO NOT STARE DIRECTLY INTO THE BEAM
In accordance with EN60825-1, EN60825-2 and US standards 21CRF
1040 and ANSI Z136, Renishaw RLE lasers are Class II lasers and
safety goggles are not required, since the blink reaction of a human
will protect the eye from damage. Do not stare into the beam or shine
it into the eyes of others. It is safe to view a diffuse-reflected beam. Do
not dismantle the unit in any way; doing so may expose laser radiation
in excess of Class II limits.
SAFETY
It is the responsibility of the manufacturer and/or encoder installation
authority to ensure that, in safety critical applications of the RLE laser
encoder, any form of signal deviation from specification or from the
limits of the receiving electronics, howsoever caused, shall not cause
the machine to become unsafe. It is also their responsibility to ensure
that the end user is made aware of any hazards involved in operation
of their machine, including those mentioned in Renishaw product
documentation, and to ensure that adequate guards and safety
interlocks are provided.
When mounting and using Renishaw laser encoder products on
machines beware of pinch and/or crush hazards that can be created
depending on how and where the equipment is mounted. This warning
is particularly relevant to the mounting of the detector heads and optics
of the RLE laser encoder.
Further information on safety is contained in Appendix E of the
installation guide.
