•
Mark the lab well with warning signs when the laser is operating and provide
interlocks for all doors.
Electrical Safety
HIGH VOLTAGE!
To prevent accidents from electrical shock, ensure
that the capacitors are completely discharged and
the power is turned off before performing any
maintenance or repairs to the system. Electric
shock and burns resulting from input power or
capacitor discharge can cause serious injury or
death.
Be aware that high voltages are present in the laser
heads once ac power is toggled on.
Safety Features
Interlocks
The Surelite has interlock switches which stop it from firing when the:
•
laser head (rod) temperature is too high.
•
laser head cover is open.
•
cooling water flow is too low.
•
external interlock (if installed) is open.
All interlocks must be OK before the Surelite will fire. If any interlock is tripped,
including the external interlock, the amber INTERLOCK LED will light and laser firing
will stop. The interlock must be reset before the laser can be restarted.
You may also wire your Surelite so that opening a door to the laser laboratory (or
opening any other switch) will shut off the laser.
Laser covers
Covers protect against stray laser radiation from the Surelite. Interlocks prevent laser
operation when they are open. Do not defeat interlock when covers are removed.
