1.3 Operation Conditions and Safety Instructions

Please read the following instructions carefully. Product reliability and lifetime probably be
affected if not following the user manual.
1.3.1. Make sure that the 24VDC power supply is connected in the correct way. Wrong
connection or input voltage might damage the product.
1.3.2. Make sure that the bending diameter of the fiber cable is larger than 15cm in anytime.
Otherwise power will decrease or the laser may even be damaged.
1.3.3. The speed of the fan is adjustable according to ambient temperature. Make sure that
minimum10cm air gaps behind and in front of the fiber laser. And the air flow direction of the
system should be the same as the laser. Short ventilation distance and wrong air flow direction
will lead to the laser temperature rises.
1.3.4. The required running ambient temperature range is 0~40℃. Laser will get internal
alarm if out of this range. It is recommended that the operating temperature range of the laser is
10-30℃. Good heat dissipation is helpful to prolong the working life of the laser.
1.3.5. Due to the "thermal lens effect" of ordinary K9 glass optical lens in medium and high
power range application, the phenomenon of focus drift, spot size inconsistency or light output
instability might occur during material processing if using K9 glass optical field lens. Fused
silica lens is recommended.
1.3.6. Please keep the fiber laser source clean especially the laser output window. Please
remember to cover the output window when it's exposed to the open environment. Dust on the
window will cause heat and damage the lens, which results in output power decrease even laser
damage.
1.3.7. Please make sure that the power is off before installing and uninstalling.
