Safety precautions

1、 Clearly labeled laser safety requirements

Laser safety level: This laser head belongs to Class II laser and clearly complies with relevant regulations of NCDRH (National Committee on Laser Safety and Standards) in the United States.

Core safety tips for Class II lasers: Under normal use, the blink reflex of the human eye can provide protection, but it is still necessary to avoid prolonged, close range direct viewing of the laser beam to prevent potential eye damage.

2、 Safety precautions derived from device characteristics

1. Electrical safety

Strictly follow the power requirements: The equipment needs to be connected to a power supply of+15 VDC ± 0.5 V (2.1 A) and -15 VDC ± 0.5 V (1.2 A). It is forbidden to use power supplies that exceed the voltage or current range to avoid short circuits, overloads, equipment damage, or electrical fires.

Pay attention to peak power consumption: When the device is preheated, the power consumption reaches 50 W (39 W during operation). It is necessary to ensure that the power supply lines and sockets can carry the corresponding power to avoid overheating of the lines.

2. Environmental safety

Control the temperature and humidity of the working environment: The working temperature should be maintained at 10-30 ° C, the humidity should be 0-90%, and there should be no condensation; Although it can withstand temperatures between -40-75 ° C in non working conditions, long-term extreme environments may affect the lifespan of the equipment and indirectly increase the risk of failure. Therefore, it is necessary to avoid storing or using in such environments.

Non working state shock prevention: The equipment can withstand an impact of 11 milliseconds and 40 grams (in the direction of the three orthogonal axes) when not working, but any severe vibration or impact should be avoided during operation to prevent beam deviation, component damage, and potential safety hazards.

3. Physical operation security

Pay attention to the weight of the equipment: The weight of the equipment is 5.5 kg. When handling or installing, make sure to hold it firmly and place it steadily to avoid falling and injuring personnel or damaging the equipment.

Material and installation compatibility: The equipment castings are made of aluminum, and the narrow legs are made of Ultem 2400 material. Matching fixing components (such as accessories corresponding to the "Narrow" or "Wide" installation methods) should be used during installation to prevent equipment displacement caused by loose installation.
