According to European Standard EN 60825-1, Clause 9 and Chinese StandardGB 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~12 kW. 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 pretect range of laser goggles over the entire range of
laser wavelengths. Please do not directly view the laser output head when laser emitting.

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 un recoverable
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 certifiedRaycus 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.

Note: The dimensions in the above diagram are in the unit of mm.
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 7.

CAUTION: All the cables can only be connected when power supply is off. Hot plug
may damage the device.
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 QBH/QD/QP output optical
cable. There are two types of protective end caps in the machine, as shown in the figure. 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).

Note: According to the difference of the protective end cap of the cable in the actual use of the customer,
some models need to replace the protective end cap. Please refer to the " Cleaning Instructions for the
Output Optical Cable Before Installation " to clean the output optical cable and the protective end cap.

3.3.2 Pre-installation cleaning instructions for output cables
a) Preparation tools
Cleaning agent: absolute ethanol, or isopropyl alcohol.
Cleaning tools: cleaning cotton swabs, dust-free paper, compressed air bottles, etc.
b) Steps
clean workbench should be turned on for at least 5 minutes , and the output optical cable
should be taken out of the black packaging box

Wuhan Raycus Fiber Laser Technologies Co., Ltd.

Figure 9 Output cable placed in the box
1) Place the output optical cable in a clean workbench;
Note: The following operations need to be carried out in a clean workbench. If the operation is
not carried out in a clean environment, it will cause great risk to the QP output optical cable;
operators need to wear finger cots to operate.
Figure 10 The output optical cable placed in the clean bench with the ventilation turned on
2) Remove the white dust cap and place it face down on new lint-free paper.
Note: The dust-free paper is for one-time use, and there is a risk of dust falling if it is used
multiple times.

Figure 11 Output optical cable with white dust cover removed
3) Use a cotton swab and anhydrous ethanol to clean the metal casing of the optical cable, then
remove the end cap (with window) attached to the optical cable, and place it on a clean paper .
Figure 12 Remove the A -type end cap on the optical cable
4) Check the cleanliness of the end caps in this state. If the cleanliness is not enough, please clean
the end caps. Please refer to the cleaning method: http://www.raycuslaser.com/view/1852.html ,
video reference: https://mp. weixin.qq.com/s/hRXrPkb8DAyvDYegSWwYLg .
Note 1: The end cap cleaning is generally performed by our professional staff. If the
customer needs to operate it by himself, we need to go through the relevant training of our
staff and obtain the relevant qualifications before the above operations can be carried out.
If the operation method is improper, it will cause irreversible and serious damage to the
output optical cable during use.
Note 2: The connection with the cutting head (or welding head) still needs to be carried
out in a clean workbench, and it is necessary to check the cleanliness and smoothness of
the relevant components of the cutting head (or welding head) itself.
