1.2 Laser Safety Grade
According to European Standard EN 60825-1, Clause 9 and Chinese Standard GB 7247.1-2012
Safety of Laser Products Part 1:Equipment Classification Requirements, this series of lasers are Class 4
laser instruments. The product emits laser radiation at a wavelength of 1080 nm or around 1080 nm, and
the average laser power radiated from the output head is 4kW~20 kW (depends on the laser type). Direct
or Indirect exposure to high power laser radiation causes damage to the eye or skin. Although the radiant
laser is not visible, 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 use 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. Please DO NOT directly view the laser output head when laser
emitting.
1.3 Optical Safety
Any dust on the end of the collimator assembly can damage the crystal of output head or the entire
laser device.
CAUTION:DO NOT emit when the protective cap is not removed, otherwise the lens or
crystal will be damaged.
1.4 Electrical Safety
a) Ensure that the PE line is effectively grounded, and the installation environment is safe and
reliable.
WARNING: The disconnection of the product grounding will electrify the enclosure,
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 unrecoverable
damage to the laser device.
1.5 Other Safety Rules
a) Do not view the laser output head directly when laser is emitting.
b) Do not use fiber lasers in dark or dim environments.
c) 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.
d) There are no user serviceable parts, equipment or assemblies inside the product. All service and
maintenance shall be performed conducted by a certified Raycus engineer. In order to prevent
electric shock, please do not break the seal or uncover the shield. Failure to comply with this
instruction will be treated as invalid warranty.

2.2 Package Parts
Please refer to package accessories in the packing box.
2.3 Unpacking and Inspection
Through the specially designed packaging materials and cabinets, Raycus ensures that the lasers are
fully protected during transportation. Nevertheless, in order to prevent unpredictable situations during
transportation, the users still need to carefully check whether the package is correctly placed before
unpacking, and there is no damage from phenomenon such as collision, cracking and flooding on the
outside of the box. Once you find that there is an abnormality in the external cabinet, please inform
Raycus Company in time to deal with it as soon as possible.
Please double check if each listed content is inside the package; and contact Raycus as soon as
possible if there are any issues.
Take extra care when removing the unit from the package and make sure that the fiber optic cable
stays away from any possible collision and vibration. Please DO NOT distort, bend or pull the output
cable when unpacking the device; and avoid any collision to the head of laser output.
CAUTION: The fiber optic cable and output head are precise optic instrument, ANY
vibration or impact to the output head, and twist or excessive bend to the cable will
damage the instrument.

2.5 Attentions
a) Make sure that the correct voltage of 380VAC is used. Connecting failure of power supply will
damage the device.
b) The output laser is collimated by the collimating lens, it is important to keep the collimating
lens clean, otherwise it will damage the device.
c) Please cap the output head when it is not in use. Do not touch the output lens at any time. Use
appropriate lens paper to clean it if necessary.
d) Safety keep the cap when using the laser. To avoid dust, make sure the opening direction of the
cap is put down.
e) Failure to follow the instructions may cause laser power loss, such loss is not covered by
warranty.

Before the laser works, make sure that the two copper contacts (Interlock pins) on the output head
are shorted, otherwise the laser will not work properly. Before installing the output cable into the
processing head, the lens of the output cable must be inspected. If the output cable lens is dirty, the lens
must be cleaned. It is forbidden to disassemble the output lens by anyone other than staff in Raycus,
otherwise the warranty will be invalidated.

3.2 Installation Rule
a) Place the laser horizontally in a suitable position and fix it as necessary;
b) Before the laser is powered on, Please check if the power supply has the correct voltage
(380VAC±10%, 50/60Hz, See “Table 2 Product technical data sheet”for details.), whether the
grounding line is well grounded;
c) Connect the power cable and control cable to the product when power supply is OFF;
d) Connect the cooling system to the laser and output optical cable head according to the water
inlet and outlet signs;
e) Please check the laser output head 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 optical cable output head, 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 40cm. When the laser is emitting light, the
minimum bending diameter shall not be less than 60cm;
i) Customers can use the four lifting rings at the top of the product or the four casters at the
bottom to lift or move the product. Before lifting the laser source, make sure that the four lifting
rings are installed firmly and reliably. When lifting the laser source, be sure to use the four
lifting rings; when pushing the laser source, please make sure that the support block at the
bottom of the horizontal adjustment caster is off the ground. After the laser source is positioned,
adjust the support block to make it contact the ground to avoid displacement of the laser source.
As shown in Figure 4(Take C20000TZ as an example).

CAUTION:
(1) The placement of the laser output cable should be as natural as possible, and the
output cable should not be twisted;
(2) If the coil diameter of the output optical cable is too small, it will damage the laser.
CAUTION:
(1) In the process of installation and disassembly, please handle the laser output head
gently, and avoid vibration;
(2) Before assembling the laser output head, ensure that the optical lens and cutting
head cavity are clean and free of pollution.
3.3 Protective End Cap of Output Cable and Using Description
3.3.1 Types of Protective End Caps and Factory Status
For multi-module high-power fiber lasers, the output cable type used is HQBH/QD/QP output
optical cable. There are two types of protective end caps in the machine, as shown in the Figure 5.
Type A end cap: It is assembled on the output optical cable when it leaves the factory. The end cap is
equipped with a protective window to ensure the cleanliness of the end cap (or crystal) during
transportation.
Type B end cap: It is attached to the packaging accessories and is generally packed in a lamination
box. The end cap is not equipped with a protective window, which is used to prevent the end cap from
being damaged when the optical cable is loaded with the cutting head (or welding head).
