Warnings
Use of controls or adjustments or performance of
procedures other than those specified within this
publication may result in hazardous radiation
exposure.
Switch off electrical power before carrying out
maintenance or servicing on the NC4 system.
Caution – Laser safety
The laser used in the Renishaw NC4 non-contact
tool setting system emits continuous visible red
light at a wavelength of 670 nm and has a power
output of less than 1 mW.
The NC4 is classified as a Class 2 laser product
as defined by International standard IEC
60825-1:1993 + A1:1997 + A2: 2001.
The product complies with 21CFR 1040.10 and
1040.11 except for deviations pursuant to Laser
Notice No. 50 dated July 26, 2001.
The standard IEC 60825-1 directs to attach a
laser warning label and explanatory label.
!
A warning label and explanatory label are
permanently fixed to each side of the transmitter
(Tx) housing (see the next page for details). An
adhesive warning label is provided for
attachment outside the machine.
Safety rules
● Do not stare directly into the laser beam.
The beam may be viewed safely from the
side.
● Avoid visual exposure to the beam with
optical appliances. Ensure that the beam is
not reflected into the eyes of another person
via a mirror or other reflective surface.
● Do not expose skin to the laser beam for
longer than is absolutely essential. Instruct
all operators about the hazards of direct eye
contact, or long skin exposure, with the
laser.
● Attach the laser warning label supplied in an
easily visible location on the machine.
● Laser operators should conform to safe
working practices agreed with the laser
safety officer.
