4.ELECTRICAL SAFETY INSTRUCTIONS.
Use this device only with a compatible and stable power supply with a
voltage fluctuation of less than 10%.
Do not connect other devices to the same fuse as the laser system
requires its full amperage. Do not use with standard extension cords or
power strips. Only surge protective devices with a rating of more than
2000 J are used.
Power this device on only if this device is well grounded, either by a firm
connection to a 3-pin socket or by a dedicated grounding cable that is
securely connected to the correct slot on the cabinet. Do not use with an
ungrounded 3 to 2-pin adapter. The grounding of the equipment should
be checked regularly for any damage or loose connections.
Therefore, the area around this laser engraving device should be kept
dry, well ventilated, and environmentally controlled to keep the ambient
temperature between 40–95°F (5–35°C). For best results, keep the
temperature at 75°F (25°C) or lower. The ambient humidity should not
exceed 70%.
When the pump is connected to its power source, do not handle the
pump or the water it is submerged in. Put it in the water before
connecting it to a power source and disconnect it from the power supply
before taking it out.
Adjustments, maintenance, and repairs of the electrical components of
this equipment must be done only by trained and skilled professionals to
avoid fire and other failures, including potential radiation exposure due to
damage to laser components. Since testing the electrical components of
this marking system requires specialized techniques, it is recommended
that such testing should only be carried out by manufacturers, sellers, or
repair service organizations.
Unless otherwise noted, adjust, maintain, and repair the appliance only
when it is turned off, disconnected from power, and completely cooled.
