1. The laser is powered by a 12v/30A switching power supply. If you accidentally misconnect the 24V power supply, don't worry, the laser will automatically start the protection circuit. At this time, the overvoltage protection indicator will shine!
2. If you accidentally connect the 12V power supply back, the laser will also start the protection circuit, so that your switching power output is directly short-circuited, while protecting the laser.
3. The marking card used in the laser is the same as that used in the optical fiber laser, and the settings are the same.
4. The installation environment of the laser and its auxiliary power supply must be well ventilated and heat dissipated, otherwise the temperature protection will be started. Please install reasonable ventilation equipment. If the laser is energized in the air temperature environment above 65 C, the red light flashes when the laser does not work, suggesting that the ventilation will be improved.
5. The laser will return heat when it shuts down for a long time in the environment above 30 C. If you turn on it immediately, there will be over-temperature protection, which belongs to the normal phenomenon. At this time, the laser can not emit laser. Please run the laser for more than 30 seconds. After the refrigeration is started, the laser can work normally again.
6. When the ambient temperature is lower than 11 C, the laser needs to be preheated for the first time. At this time, the blue preheating indicator lights up. When the preheating temperature exceeds 11 C, the laser works automatically.
7. The laser belongs to the intense laser. It can't be aimed at people or inflammable objects or hit the laser on the high reflector.

Matters needing attention:
1. This product belongs to four kinds of lasers. It outputs high power invisible light. It is forbidden to look directly. When operating, please wear laser protective glasses.
2. Do not shine the light beam on the reflector, so as not to cause harm to people.
3. Non-professionals are prohibited from operating.
4. Before installing the laser, please pay attention to anti-static, require static protection, and wear anti-static wrist guard to prevent static electricity from breaking down internal devices.
5. Install or disassemble, power off please! For your safety and equipment, do not operate live.
6. Before starting, please check the connection correctly and tightly again.
7. Do not use in high humidity environment.
8. Laser is forbidden to be disassembled, or not to be guaranteed!
9. If the performance of the external switching power supply is not good and the voltage fluctuation of the power supply exceeds 13V, the laser will be cut off and protected to prevent the lifetime of the laser from being affected.
Advantages compared with similar products:
1. It has multiple circuit protection measures, over-voltage protection, power supply connection counter-protection and so on.
2. The main body of the product is made of aluminium alloy, which improves the competitiveness of the product.
3. The circuit and optical circuit design are advanced, and the electro-optical conversion rate is higher than that of similar products.
4. Low failure rate, low maintenance cost, saving maintenance costs for customers.
