7. Electrical Hazard
1.2 Laser Safety Grade
According to European Standard EN 60825-1, Clause 9, this series of laser products are Class 4 laser
products. This productemitslaser radiation ata wavelengthof 1080 nmor around 1080 nm, and the average
laser power of the products listing in this User Guide radiated from the fiber delivery cable is ranged from
3000W to 12000W (depending on the product model). Either directly or indirectly being exposed to high
power laser radiation will bring permanent damage to the eye or skin. Even though the radiant laser is not
visible at the wavelength of about1080nm, the beam will cause irreparable damage to the retina or cornea,
so appropriate and certified laser safety glasses must be worn throughout the laser emitting.
WARNING: Users must wear appropriate laser goggles when operating
this device. The laser goggles should be selected according to the range
of wavelength emitted from this product. Users must ensure that the
protect range of laser goggles over the entire range of laser wavelengths.
It is forbidden to watch the laser fiber delivery connector during laser
emission.
1.3 Optical Safety
The dust on the end of the fiber delivery connector may bring damage to the lens or the entire laser
device.
CAUTION: DO NOT emit the laser when the black plastic protective
cap is not removed, otherwise the lens or the crystal will be damaged.
1.4 Electrical Safety
a) Ensure that the product is effectively grounded, and the installation environment is safe and
reliable.

Wuhan Raycus Fiber Laser Technologies Co., Ltd.
User Guide of RFL-C3000XZ~RFL-C12000XZ

WARNING: The disconnection of the product grounding will cause the
product shell to become electrified, which may result in personal injury
to the operator.
b) Ensure that the AC voltage is supplied normally.
CAUTION: Wrong wiring mode or power supply voltage will cause an
irrecoverable damage to the laser device.
1.5 Other Safety Guidelines
a) DO NOT watch the fiber delivery connector of the product directly by anytime when the product
is powered on.
b) DO NOT use the product in a dark or dim place.
c) If the product is used in a manner not specified in this document, the resulted impairment to the
laser will not be covered by the warranty.
d) There are no user serviceable parts, equipment, or assemblies inside the product. All service and
maintenance shall be performed and conducted by the Raycus engineer or authorized personnel.
In order to prevent electric shock, DO NOT break the seal or remove the shell. Failure to comply
with this instruction and the resulted impairment to the laser will not be covered by the warranty.

connector are shorted well, otherwise the laser will not work properly.
c) Before installing the fiber delivery cable connector into the laser processing head, the lens of the
fiber delivery cable must be inspected carefully.
d) If the fiber delivery cable lens is dirty, the lens must be cleaned well. It is forbidden to disassemble
the protective lens by anyone other than staff of Raycus or Raycus authorized personnel, otherwise
the warranty will be invalidated.
3.2 Installation Requirements
a) Place the laser horizontally in a suitable position and fix it as necessary;
b) Before the laser is powered on, check if the power supply has the correct voltage (AC 323V ~ 437V,
50/60Hz, see Table 2 Product Technical Data Sheet for details), and the grounding line (PE)shall be
well grounded all time during powering on;

e) Please check the laser fiber delivery connector and make sure to clean it before installing it in the
equipment;
f) DO NOT step on, squeeze, or excessively bend the protective tube during the installation of the
output optical cable to avoid damage to the optical fiber;
g) In the process of installing the fiber delivery connector, ensure the cleanliness of the surrounding
environment (DO NOT use electric fans to dissipate heat when it is hot in summer to avoid large
dust in the air);
h) The minimum bending diameter of the laser transmission cable in non-working conditions such as
transportation and storage shall not be less than 20cm. When the laser is emitting, the minimum
bending diameter shall not be less than 30cm;
i) Users can use the four rings on the top of the product to carry the product or the four casters at
bottom to move it. As Figure 6, and MUST check that the rings are firmly installed and that the
casters are fully active before lifting the laser.

CAUTION: All the cables can only be connected when power supply is off. Hot
plug may damage the device.
CAUTION:
a) The placement of the laser delivery cable should be as natural as possible,
and the delivery cable should not be twisted;
b) If the coil diameter of the delivery optical cable is too small, it will damage
the laser.
CAUTION:
a) In the process of installation and disassembly, please handle the laser fiber
delivery connector gently, and DO NOT subject it to vibration;
b) Before installing the laser fiber delivery connector, ensure that the optical lens
and laser processing head cavity are clean and free of pollution.

3.3.1 Requirements for Cooling Water:
a) The cooling water connection of the laser is shown in Figure 7, and the arrow direction represents
the flow direction
b) The cooling water uses the pure water, may use the drinking pure water.
c) Inorder to prevent the growthof mold thatmay lead to water blockage of the product, adding alcohol
solution to about 10% portion of the total volume is recommended.
d) If ambient temperature is between -10℃and 0℃, it is recommended to usethe 30% portion volume
alcohol, and replace it by every 2 months entirely.

e) If the ambient temperature is below -10℃, the cooling system (chiller) with both heating and cooling
functions must be activated, and shall keep it in full-time operation by 24 hours to avoid the fiber
delivery cable connector and modules inside the product that containing the always waterways from
freezing.

3.3.2 Requirements for Delivery Cable Cooling System:
a) Water flow requirements:
b) RFL-HQBH model fiber delivery cable: 1.5L~2.0 L/min
c) RFL-QD model fiber delivery cable:2.5~3.0 L/min.
d) Pressure of liquid flow: < 0.6 MPa at the inflow.
e) Type of liquid exchange junction: Two-Touch Fitting M5 to ϕ6 mm.
f) Type of tube: outer diameter ϕ6 mm; inner diameter ϕ4 mm.
g) Direction of cooling liquid: unidirectional; connect the tube with the water-pipe strictly according to
direction shown on the layer of the tube.
h) Type of liquid: de-ionized water, condensed water, purified water; it is recommended to replace the
coolant once a month, not exceeding two months at most.

i) PH value of liquid: 5.5 ~ 9.
j) Filter element/cartridge is needed for the cooling system, and the size of the solid residual particles
should be ≤ 100 μm; replace the filter element/cartridge once a month.
k) Maximum temperature of liquid: 45 ℃.
l) Minimum temperature of liquid: 5 ℃above the saturated dew-point.
m) Additive to the liquid: satisfies the requirements of PH value and size of solid residual particles as
above.
n) Radius of the bending of the armored pipe: off-work state (i.e., transportation and reservation):
minimum radius of bending ≥ 15 cm; in-work state: minimum radius of bending ≥ 20 cm.
o) Long-term vibration < 2 G; Impact < 10 G.
3.3.3 Other Requirements:
a) When initiating the cooling system before using the product eachtime, check the entire water system
and joints to prevent the water leakage. The external water pipe must be installed and connected
according to the water inlet (IN) and water outlet (OUT) identified on the rear panel of the product.
Otherwise, the product may not work properly.
b) If the product is not used for a long time, the cooling water inside the cooling system and the product
should be drained totally, and then both the inlet and outlet must be covered with proper caps.
Otherwise, the product may be damaged due to the frozen.
c) Please use compressed gas below 0.5 MPa when draining the water from the product. Failure to do
so may cause permanent and irrecoverable damage to the cooling system.
CAUTION:
a) Set the water temperature of the cooling system correctly according to the
ambient temperature. If the water temperature was set too high, it will result in
the product de-functioning. If the water temperature was set too low, it will cause
condensation inside the product or the laser fiber delivery cable, which will cause
damage to the product as well;
b) Before turning on the product, the cooling system must be working properly and
the water temperature should be suitable for the temperature.
