Electrical Safety Instructions - Omtech LYF-175S User Manual

1 Safety Information
• DO NOT use or leave sensitive EMI equipment nearby. Ensure the area around the laser is free
of strong electromagnetic interference during any use.
• ONLY use this machine as described in the Material Safety section of this manual. The laser
settings and engraving process must be properly adjusted for specific materials.
• Ensure the area is kept free of airborne pollutants, as these might pose a similar risk of
reflection, combustion, etc.
• NEVER use this marking machine with the fiber source's housing open, as the closed laser light
path is necessary to prevent laser radiation leakage.
• DO NOT modify or disassemble the laser and do not use the laser if it has been modified or
disassembled by anyone except trained and skilled professionals. Dangerous radiation exposure
and other injury may result from the use of adjusted, modified, or otherwise incompatible
equipment.

1.5 Electrical Safety Instructions

• ONLY use this device with a compatible and stable power supply with less than 5% fluctuation in
its voltage.
• DO NOT connect other devices to the same fuse, as the laser system will require its full
amperage. Do not use with standard extension cords or power strips. Use only surge protectors
rated over 2000J.
• ONLY turn on the power to this device when it is well grounded, either via a firm connection
to a 3-prong outlet or via a dedicated ground cable firmly connected to the proper slot on the
back of the main tower. Do not use with an ungrounded 3-to-2 prong adapter. The device's
grounding should be checked regularly for any damage to the line or loose connections.
• Turn the device on and off using its key and power buttons in the correct order. The
mainboard, galvanometer, and laser have separate power supplies that are grounded
in order. Activating everything at once, too quickly, or in the wrong order may send
electrical current to an ungrounded component, causing short circuits and other
electrical hazards.
• ONLY use this device with one hand at a time. The laser is powered by an extremely high
voltage connection and placing two hands on the machine at one time during operation has the
potential to create a closed circuit with the human body, resulting in electrical shock.
• The area around this laser marking device should be kept dry, well ventilated, and
environmentally controlled to keep the ambient temperature between 40 ℉ –95 ℉ (5 ℃ –35 ℃ ).
The ambient humidity should not exceed 70%.
