Electrical Safety Instructions
• ONLY use this device with a compatible and stable power supply with less than 5%
fluctuation in its voltage.
⚫ 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 grounding cable firmly connected to the
proper slot on the back of the main tower. Do not use with an ungrounded 3 to 2 prong
adapters. 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, galvo, 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°F (5–35°C).
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 required for testing the electrical components of this marking
system, it is recommended such testing only be done by the manufacturer, seller, or
repair service.
⚫ Unless otherwise specified, ONLY undertake adjustment, maintenance, and repair of the
device when it is turned off and disconnected from its power supply.
