3. SAF ET Y NOTES
When doing so, note the electrical characteristic values of
the integrated interlock switches in the microscope. You
must not exceed these values by connecting a laser beam
interrupter, as otherwise the interlock switches will be
damaged and no longer function safely and reliably:
Maximum permitted electrical characteristic values of the
integrated interlock switch:
Umax= 40 V DC
Imax= 0.2 A
The integrated interlock switches in the microscope and
their wiring with a laser beam interrupter/laser ensure that
the laser radiation you coupled into the microscope cannot
get into the user's eyes through the eyepieces.
Important safety note
In addition, observe the safety hazards described in
Section 3.3.3.3 to 3.3.3.6!
3.3.4. Exception for Class 1 lasers
Coupling a laser of Class 1 in accordance with IEC/EN
60825-1 into a microscope does not result in any danger to
the user.
The listed safety hazards apply only for lasers of Class 1M,
2, 2M, 3R, 3B and 4.
Note that the rules and regulations of the United States FDA
21CFR1040.10 Class I (CFR – Code of Federal Regulation Title
21, revised as of April 1, 2011) do not distinguish between
Class 1 and 1M. Thus the statement that there are no safety
hazards on the microscope do not apply for the laser clas-
sification in accordance with FDA Class 1.
