7: Electrical Hazard
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 6kW-~10kW (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 crystal of fiber delivery cable
connectoror 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
damages to the laser device.
1.5 Other Safety Rules
a) Do not view the fiber delivery cable connector 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 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.

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 above may cause laser power loss, and such loss is not
covered by warranty.

Before the laser works, make sure that the two copper contacts (Interlock pins) on the fiber delivery
cable connector 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 ground 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.), and check
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 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.
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 5.

Requirements of Cooling Water:
a) Cooling water needs to be pure water;
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 every two 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.

Wuhan Raycus Fiber Laser Technologies Co., Ltd.
User Guide of RFL-A6000D~10000D

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:
(1) 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;
