optical output cable can cause serious damage to the laser.
3.3 Cooling Requirements
1. Raycus RFL-QCW150/1500 fiber laser has fans for active cooling.
2. Make sure there is sufficient airflow to cool the device when the laser is operating. Of
course, the laser can also be operated where the ambient temperature is maintained at
40℃constantly with an air-conditioner.
3. In front and rear panel of the laser is respectively provided with an air inlet port and an
air outlet port, thus there must have ample room at the in front and rear panel of the laser for air
circulation.
4. The window shutter with dust proof cover in front panel of the laser is removable.
Customers are required to disassemble and clear the dust proof cover regularly for air circulation.
3.4 Installation Procedures
(1) Place the product in an appropriate position, immobilize it if necessary.
(2) Check if the power supply has the correct voltage (48±10% V DC), and the earth line is
connected reliably.
(3) Connect the power cable and control cable to the product when power supply is OFF.
(4) Check the optical output head and clean it if necessary before install it. This procedure
must be performed by Raycus personnel or person authorized by Raycus. If you find any dust or
something that cannot be removed from the lens, stop installing the product and contact Raycus
immediately.
(5) Prevent the delivery cable from treading, pinching or excessive bending during
installation.

(6) During the installation and disassembly process, please take care to gently put the laser
output head, do not be shocked.
(7) In the installation of laser output and output head process, please make sure that the
surrounding environment is clean, otherwise it may pollute the output head(do to use fans to
avoid dust)
(8) The optic fiber cable must not be bent with the radius less than 20 cm during
transportation，storage and 30 cm when in operating.
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.
CAUTION:
Make sure the aperture and the cavity of the processing head is clean.
Keep the protective cap properly, prevent it from contamination. Or
the aperture will be contaminated when capped.

Figure 13 Pin number of DB-25 interface connector
Interface wire specification
The minimum wire gage is 18AWG at 15 meters (30 meters maximum regardless of gauge).
The gage of the wire must increase as the distance increases. For connectivity, the wiring and/or
cabling must have an overall shield to ensure proper functionality. The shield is to cover over all
conductors and terminate at the unit where the conductors enter/exit the unit.
