SAFETY ITERLOCK
The laser system incorporates a safety interlock having an electrical potential of 24V DC
between terminals. When the top enclosure of the chassis is removed, the terminals of the
interlock connector at the front of the enclosure are no longer in contact and the laser beam will
be blocked by the shutter. A shorting plug, called an interlock defeat tool, is provided to override
the safety interlock for testing and alignment procedures only. The diagram below is an electrical
schematic detailing the interlock system and the interlock defeat tool.
Caution:
The interlock defeat tool is utilized only when the top enclosure must be removed
for testing purposes and beam alignments.
Laser safety glasses must always
be worn when the defeat tool is in use.
Failure to wear appropriate eye
protection can result in severe eye damage.

ELECTRICAL SAFETY
A NEMA type 1 service box mounted to the right side of the machine contains all of the exposed
120 Volt AC in the system. The box encorporates a lockable electical disconnect and a screw
driver is required to open the lid. This box should only be accessed by qualified service personel
