2-6 Laser Safety and Compliance
CDRH Requirements for Operating the Laser System
Interlock Connector
The 2-pin interlock connector on the laser head rear panel (Figure 2-5) can be wired to
an external interlock switch. Either rewire the provided jumper plug (i.e., remove the
short,
Figure 2-7) or provide a similar plug and wire the two contacts to a perimeter
safety switch that is attached to an access door or to auxiliary safety equipment. Wire
the switch as “normally closed” so that when the door or safety device opens, the switch
opens, thereby tuning off the power to the diode laser. This prevents unaware personnel
from getting hurt.

CDRH Requirements for Operating the Laser System
The InSight X3 laser head and the power supply comply with all CDRH safety
standards. However, if either is embedded into another system where an emission
indicator is not readily visible or the power supply interlock key is not accessible, the
following functions must be provided by the user to satisfy CDRH regulations:
Emission indicator — Indicates that laser energy is present or can be accessed. It
can be a “power-on” lamp, a computer display that flashes a statement to this effect,
or an indicator on the control equipment used for this purpose. It need not be marked
as an emission indicator so long as its function is obvious. Its presence is required
on any control panel that affects laser output, including the computer display panel.
Safety key —Prevents unauthorized use. The password feature of your personal
computer, either in the CMOS Setup program or the Windows operating system,
meets this requirement.
Maintenance for CDRH Compliance
This laser product complies with Title 21 of the United States Code of Federal
Regulations, Chapter
1, subchapter J, parts 1040.10 and 1040.11, as applicable. To
maintain compliance with these regulations, once a year or whenever the laser system
has been subjected to adverse environmental conditions (e.g., fire, flood, mechanical
In order for the power supply to turn on, the two contacts of the
interlock connector must either be wired to a normally closed
safety switch or be shorted together using the jumper plug
provided.
