1.2 Laser Safety Grade
This series of lasers are Class 4 laser instruments. The product emits laser radiation at a wavelength
of 915nm or around 915nm, and the average laser power radiated from the fiber delivery cable connector
is 4kW~12kW (depending on laser model). Direct or Indirect exposure to high power laser radiation
causes damage to the eye or skin. Although the radiation is not visible, the beam will cause irreparable
damage to the retina or cornea, so appropriate and certified laser safety glasses must be worn whenever
the laser is emitting.
WARNING: Users must use appropriate laser goggles when operating this device. The
laser goggles are selected according to the range of wavelength emitted from this product.
Users must select the appropriate laser goggles according to the entire range of laser
wavelengths. Please do not directly view (whether the laser Is emitting or not) the laser
output heads when laser emitting.
1.3 Optical Safety
Any dust on the end of the collimator assembly can damage the lens 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
outer shell, 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 irreversible damage
to the laser device.
1.5 Other Safety Rules
a) Do not view the laser output head directly when laser 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 manual, 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 conducted by a certified Raycus engineer. In order to prevent electric shock,
please do not break the seal or uncover the shield. Otherwise, any damage to the device will not
be guaranteed.

2.5 Attentions
a) Make sure the product is properly grounded before use.
b) Make sure that the correct voltage of 380VAC is used. Power supply connection failures will
cause irreversible damages the device.
c) It is important to keep the collimating lens clean, otherwise it will cause irreversible damages the
device.
d) When not using the laser, please cover the fiber delivery cable connector protection cap, do not
touch the lens of the output, when necessary, use special dust-free cotton swabs and alcohol to
clean the lens.
e) Please keep the protective cap of fiber delivery cable connector properly when using the laser. To
avoid dust, make sure to place the protective cap with the opening facing downward.
f) High temperature in summer may cause condensation to form inside the laser, which may cause
permanent damage to the laser, please ensure that the laser is shut down with the water cooler
being stopped at the same time.
g) low temperatures during the winter can cause the laser's internal cooling water to freeze easily,
causing permanent damage to the laser, please ensure that when the laser is in the shutdown state,
the water cooler continuous operation.
h) Failure to follow the instructions may cause laser power loss, and such loss is not covered by
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 staffs from Raycus,
otherwise the warranty will be invalidated.
3.2 Installation rules
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, 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 fiber delivery cable connector according to the water
inlet and outlet signs.
e) Please check the fiber delivery cable 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 fiber
delivery cable connector to avoid damage to the optical fiber.
g) In the process of installing the fiber delivery cable connector, ensure the cleanliness of the
surrounding environment (do not use electric fans to dissipate heat when it is hot in summer to

b) In order to prevent the water in the water cooler from growing mold and causing pipeline
blockage, it is recommended to add alcohol when filling pure water, and the amount of alcohol
added is 10% of pure water.
c) When the ambient temperature of the equipment is between -10 ℃ and 0 ℃, the glycol solution
with a volume ratio of 30% must be used and replaced it every 2 months.
d) If ambient temperature is below -10℃, the chiller with both heating and cooling functions must be
used and kept in full-time operation.
Water cooling requirements for output optical cables:
a) Water flow requirements: iHQB fiber delivery cable connector water flow rate greater than
1.5L/min; QD fiber delivery cable connector water flow rate greater than 2.5L/min.
b) Water cooling pressure:4～6 Bar at the water inlet.
c) Water inlet and outlet connector type: iHQB output fiber optic cable ϕ6 quick release connector;
QD output fiber optic cable ϕ8 quick release connector.

d) Water pipe type: iHQB fiber delivery cable connector outer diameter ϕ6 inner diameter ϕ4; QD
fiber delivery cable connector outer diameter ϕ8 inner diameter ϕ5.5.
e) Cooling water quality: deionized water, distilled water, purified water; it is recommended to
replace the water once a month, and the replacement period should not exceed two months.
f) PH value of cooling water: 5.5～9.
g) The water cooler needs to be equipped with a filter element whose filter particle size is less than
100um; the filter element needs to be cleaned once a month.
h) Maximum cooling water temperature: 35℃.
i) The lowest cooling water temperature: 5℃ greater than the saturated dew point temperature.
j) Additives in cooling water: meet the above PH value and solid particle size requirements.
Other requirements:
a) When starting the cooling system for the first time, check the entire water system and joint for
water leakage.
b) If the laser is not used for a long time, the cooling water inside the cooling system and the laser
inside should be drained, otherwise the laser equipment will be damaged.
c) Please use compressed gas below 0.5MPa when emptying water from the device. Failure to do so
may cause permanent equipment damage to cooling system.
CAUTION:
a) Set the water temperature of the cooling system correctly according to the ambient
temperature. Setting the water temperature too high will result in the laser not working
properly. Setting the water temperature too low will cause condensation inside the laser or the
laser output head, which will cause damage to the laser.
b) Before turning on the laser, the cooling system must be working properly, and the water
temperature should be suitable for the temperature.
