SAFETY
DEFINITIONS
CHASSIS GROUND Symbol
CAUTION: A condition that has the potential to
cause damage to property or instrument.
WARNING: A condition that has the potential to
cause bodily harm or death.
GENERAL
• Observe all Cautions and Warnings both in the User
Guide and on the instrument.
•
Use the QCL instrument as specified in this guide or the
protection provided by this instrument may be impaired
and the warranty will be voided.
• Use good laser safety practices when using the QCL
instrument.
• Before proceeding, it is critical that you take precautions
to prevent electrostatic discharge (ESD) damage to your
laser.
• Locking the instrument with the keyswitch disables the
output current. The key can only be removed when in the
LOCK position.
POWER CORDS
• This equipment is grounded through the AC power cord
grounding conductor.
• Use only the earth-grounded power cords that are
recommended in this user guide.
• Route power cords and other cables so that they cannot
be damaged.
• Position the QCL instrument in a location that makes it
easy to quickly disconnect the power cord.
•
To avoid fire hazard, use only the specified power cords
with the correct grounding, voltage, and current ratings.
FUSES
• Disconnect the power to the QCL instrument before
changing the fuses.
• To prevent damage to the QCL instrument when replacing
fuses, locate and correct the problem that caused the fuse
to blow before re-applying power.
•
To avoid fire hazard, use only the specified fuse with the
correct type number, voltage, and current ratings, and use
only the recommended replacement parts.
CAUTIONS
The QCL instrument has no user-serviceable parts.
Other than the fuses, the QCL instrument is not
designed to be maintained by the user nor does it
contain any parts that can be repaired by the user.
All maintenance and repairs must be performed by
Wavelength or the warranty will be void.
Use a soft cloth to remove dust from the QCL
instrument. Do not expose the QCL instrument to
any liquids, sprays, or solvents. To avoid electrical
shock, unplug the power cord before cleaning the
instrument.
Before connecting to the power source, make sure
the correct cables and voltage for your area are
set. The voltage selection is available on the back
of the instrument. See the Quick Start Guide for
instructions on changing the voltage.
WARNINGS
Position the QCL instrument so that access to the
Main Power On/Off switch on the back panel is
easily accessed.
Do not use the QCL instrument if there is evidence
of damage from shipping; damaged equipment
can present significant safety hazards. If you
suspect the QCL instrument is damaged, contact
Wavelength technical support before attempting to
operate the instrument.
To avoid electrical shock, use the recommended
earth-grounded power cables and properly earth-
grounded, 3-prong receptacles only. Failure to
follow this precaution can result in severe injury.
To avoid injury, do not tell the engineers how to
do their jobs. Let them muddle through until they
decide to read the User Guide.
