WARNING: Blindness hazard! Always wear eye protection when
the laser safety shields are open, such as during service. Direct or
diffuse laser radiation can damage eyes. Goggles must block
10.6 µm laser radiation. Goggles protect against scattered energy
but not against direct viewing of the laser beam or reflections
from metallic surfaces.
WARNING: Serious burn hazard! Direct or diffuse laser radia-
tion can cause serious burns. Keep hands and other parts of the
body out of the path of the laser bean when servicing.
WARNING: Toxic fume hazard! Laser marking generates vapors,
fumes, and particles that may be noxious, toxic, or even fatal.
Follow maintenance procedures on the fume extractor. Use
proper ventilation.

Laser Safety Interlocks
The Option Bay has five laser safety interlocks that prevent the laser from
firing when any safety shield on the Option Bay is removed. To physically
enable the laser, all laser safety interlocks must form a complete electrical
circuit to the laser’s safety inhibit input. When activated, (i.e., when any
safety shield is removed) the safety interlock disables the laser’s safety
inhibit circuit. Activation of the safety interlock prevents (via hardware in
the laser itself) the laser from firing. A laser safety interlock is shown in Fig-
ure .
Figure 1-12—Laser safety interlock
The five laser safety interlocks are located:
1. Behind the removable safety shield on the front (toward the PS288) of
the Option Bay
2. Behind the removable safety shield on the upper left side of the Option
Bay
3. Behind the removable safety shield on the top of the Option Bay
4. Behind the removable safety shield on the upper right side of the
Option Bay
5. Behind the removable safety shield on the lower left side of the Option
Bay

The laser safety interlocks can be overridden for service. To override a laser
safety interlock, pull out on the switch. The laser can now fire with the safety
shield removed.
WARNING: The laser safety interlocks should be overridden only
by qualified and trained service personnel.
WARNING: Never leave system unattended with safety shield
removed and safety interlocks overridden. Serious burn hazard!
Direct or diffuse laser radiation can cause serious burns. Blind-
ness hazard! Direct or diffuse laser radiation can damage eyes.
