1.3 Operation conditions and safety instructions

Please read the following instructions carefully. Product reliability and lifetime probably be
effected if not following the user's manual.
1) Make sure the +24VDC power supply is connected in the correct way. Wrong connection or
input voltage might damage the product.
2) Make sure the bending diameter of the fiber cable is larger than 15cm in anytime. Otherwise
will cause power lost even laser damage.
3) Make sure 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 rise.
4) The laser running ambient temperature range is 0~40℃, laser will get internal alarm if out of
this range. It's a protection action to insure the lifetime of the laser.
5) 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 lost even laser damage.
6) Please make sure the power is off before installing and uninstalling the fiber laser.
7) Please do not look at the output window anytime when power on, and wear laser safety goggle
when operating the fiber laser.
