1.1 Symbols Used in this User Guide
WARNING: Describes a hazard that lead to a personal injury or death.
CAUTION: Describes a hazard that lead to a minor personal injury
or product damage.
1.2 Laser Classification
This series of lasers are classified as a high power Class 4 laser
instrument according to the European Community standards EN 60825-1, clause
9. This product emits invisible laser radiation at or around a wavelength
of 915 nm, and the total light power radiated from the optical output is
greater than 200W. Direct or indirect exposure of this level of light
intensity may cause damage to the eye or skin. Despite the radiation being
invisible, the beam may cause irreversible damage to the retina and/or cornea.
Appropriate and approved laser safety eyewear must be worn all the time while
the laser is operational.

2.8 Installation Procedure
a） Check if the power supply has the correct voltage (48VDC±10%), and
the earth line is connected, make sure it is firm and reliable;
b） Place the product in an appropriate position, immobilize it if
necessary;
c） Connect the power cable and control cable to the product when power
supply is OFF;
d） Check the output head and clean it if necessary. This procedure must
be performed by Raycus personnel or person authorized by Raycus. Make
sure the environment is clean, or the output head may be contaminated.
It is prohibited to use fan during installation, which will cause
dust in the air;
e） Prevent the delivery cable from treading, pinching or excessive
bending during installation.
CAUTION: All the cables can only be connected when power supply is off.
Hot plug may damage the laser.
CAUTION: Ensure that there are no fiber bends with radius less than 20cm

during the robotic arm movements. Tight bends will damage the laser
delivery system.
When the product is in storage, the bending radius of the delivery cable
should be more than 20cm.
CAUTION: Avoid vibration and impact to output head, or it may be damaged.
CAUTION: Make sure the aperture and the cavity of the processing head
is clean;
Keep the protective cap properly, prevent it from contamination; Or the
