1Safety Information
Thank you for choosing Raycus fiber laser. This User Guide provides important safety, operation,
warranty and other information. Please read it carefully before you use this product. In order to
ensure safe operation and optimal performance of the product, please follow the warnings,
cautions, operating procedures and other instructions accordingly.
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 1064 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.

1.5 Electrical Safety
(1) Make sure your product is grounded through the PE line of the AC power cord. The
grounding must be firm and reliable.
WARNING: Any interruption from the protective earth will electrify
the enclosure, which may result in personal injury.
(2) If the fuse blows out, replace it with only the same types and ratings. The use of other fuses
or material is prohibited. You can contact Raycus for the information of the fuse.
(3) Make sure that the correct voltage of the AC power source is used.
CAUTION: Failure to connect the laser to the correct voltage could
damage the product.
(4) There are no operator serviceable parts inside, so do not try to remove covers, or electrical
shock may be caused, and warranty will be void.
1.6 Other Safety Rules
(1) Never look into the laser output port when power is supplied to the laser.
(2) Avoid using the laser in a dim or darkened environment.
(3) If this device is used in a manner not specified in this document, the protection provided by
the device may be impaired and the warranty will be voided.
(4) Do not remove the covers of the laser, or the warranty will be void. All maintenance must be
performed in Raycus or by qualified Raycus personnel.

Water temperature setting:
Summer (ambient temperature higher than 30℃) 29±1℃;
Winter (ambient temperature lower than 30℃) 25±1℃
Requirements on Cooling Water:
Purified water should be used. In order to prevent mould growing that may lead to pipe blockage,
we recommend to add alcohol about 10% of the total volume. The cooling system should be
equipped with filter. Check and clean the filter every six months.
If the product is used in an environment that ambient temperature is between -10℃and 0℃, we
recommend to use 30% alcohol(volume ratio), and replace it every 2 months.
If the product is used in an environment that ambient temperature is below -10℃, you must use
chiller with both heating and cooling functions, and keep it in full-time operation.
Other requirements:
Before you start the laser, ensure that the supply and return connections are correct, and confirm
that there is no leakage in all the water circuits. Any abnormal condition in the water circuits
may cause a failure to the operation of the laser.
If you will not use the laser for a long time, water must be emptied from the product, and then
both the inlet and outlet must be blocked with the nuts we provide. Failure to do so may lead to
permanent equipment damage.
CAUTION: Please set the water temperature in strict accordance with the
requirements above. Too low temperature may lead to condensation on the
laser module and the output head. This can cause serious damage to the
equipment.

User’s guide Ytterbium Pulsed Fiber Laser RFL-P200 Ver.: 1.0

CAUTION: The cooling system should be turned on first. Check any
water leakage and make sure that the water temperature reaches the set
point before you start the laser(Summer: 29±1°C; Winter: 25±1°C).
3.3 Installation Procedure
(1) Check if the power supply has the correct voltage (Single-phase 220VAC±10%，50/60Hz),
and the earth line is connected, make sure it is firm and reliable;
(2) Place the product in an appropriate position, immobilize it if necessary;
(3) Connect the power cable and control cable to the product when power supply is OFF;
(4) Insert the water pipes into the inlet and outlet;
(5) 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;
(6) 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 30cm when the
product is installed. Avoid excessive twisting and tight bends during the
robotic arm movements. Tight bends will damage the laser delivery
system.

User’s guide Ytterbium Pulsed Fiber Laser RFL-P200 Ver.: 1.0
15
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: Removal of protective glass of the output head is prohibited
for the user.
