DANGER
H
azard due to lack of effectiveness of the protective device
Persons and parts of the body to be protected may not be recognized in case of
non-observance.
b
Only mount deflector mirrors to solid walls or machine components. The position
of the deflector mirrors must not change after alignment.
b
Do not use deflector mirrors if contamination, beading water, condensation, or
frost on the deflector mirrors is to be expected.
b
Make sure that the deflector mirrors are intact and free of scratches, contamina‐
tion, beading water, condensation, frost, etc. at all times.

15.5.2 Mounting
To mount the deflector mirrors, use the included swivel mount brackets.
15.5.3 Change in scanning range using deflector mirrors
Important information
NOTE
The use of deflector mirrors reduces the scanning range depending on the number of
deflector mirrors in the protective field.
