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 1080 nm, and the total light power radiated from the
optical output is greater than 1000W/1200W/1500W (depending on model). 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.

Note: The two interlock pins on the output terminal must be shorted before the laser is turned on.
Usually there is shorted contacts in the processing head, please check the head to ensure that.
3.2 Installation Procedure
(1) Check if the power supply has the correct voltage (380VAC±10%，50/60Hz), and the earth
line is connected reliably.
(2) Place the Fiber Laser Module firmly on the desirable position.
(3) Check the output terminal and clean it if necessary.This procedure must be performed by
Raycus personnel or person authorized by Raycus.
(4) Connect the power cable and control cable to the Fiber Laser when power supply is OFF.
(5) Insert the water tube into the inlet and outlet.

(6) The optic fiber cable must not be bent with the radius less than 30 cm during transportatio n，
storage and when in use.
There are four swinging rings on the top of the product and four wheels on the bottom, with
which you can lift or move the product. The rings and wheels are shown in Figure 3
1. Swinging rings; 2. Wheels
Figure 3: The Swinging Rings and Wheels on the Product
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 30
cm. Avoid excessive twisting and tight bends during the robotic arm
movements. Tight bends will damage the Laser system.

There are additional cooling requirements for the QBH head. The head should be cooled with an
independent water circuit. A chiller with double temperature outputs is a good option, and an
individual chiller is also a proper choice. The cooling capability should be higher than 600W,
minimum flow should be 2L/min, outside diameter of the pipe should be 6mm, and the most
important, the maximum pressure is 2bar, and de-ionized water must be used.
CAUTION:
The water pressure to the QBH output head must be less than 2bar, or the
head will be damaged. Such damage is not covered by guarantee.
Wate r temperature setting:
Summer (ambient temperature higher than 30℃) 29±0.5℃;
Winter (ambient temperature lower than 30℃) 25±0.5℃
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 total volume. The cooling system should equip 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, 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.

When connecting to the laser for the first time, ensure that the flow and return connections are
correct.
Other require ments:
Ensure that the supply and return connections are correct.
If you will not use the laser for a long time, water should be emptied from the pipe, and then
block inlet and outlet. 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 in the
Laser module and the output head. This can cause serious damage to the
equipment.
CAUTION: The cooling system should be turned on first.Check any water
leakage and make sure that the water temperature reach the set point before
you start the laser.

3. LASER: Laser emission button, it‟s a button with a red indicator. In hyper terminal mode and
AD mode, when this button is pressed down, the product is ready to emit laser, and the LED
illumines. Press again will release the button, and disable the laser emission. It is also for
shifting the laser and red guide laser. When laser emission is enabled, the red guide laser is off;
when the laser emission is disabled, the red guide laser is on.
4. ALARM: Alarm indicator, indicates a fault condition, when the yellow LED illumines.
5. EMERGENCY STOP: Press it down to stop the laser immediately, turn it clockwise to
release. But the laser cannot start before it‟s powered on (use the key switch) for a second
time.
