Electrical Safety Instructions - Vevor Flm-R30-Ft Mode D'emploi

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.

2.4 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%.
•Adjustment, maintenance, and repair of the electrical components of this device must be done
ONLY by trained and skilled professionals to avoid fires and other malfunctions, including potential
radiation exposure from damage to the laser components. Because specialized techniques are
