1.7 Electrical Safety Instructions

• ONLY use this machine 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 2000 J.
• 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 cabinet. 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.
• DO NOT use standard surge protectors, extension cords, or power strips. Only use
additional wiring thick enough to safely handle the full load of the machine.
• DO NOT open the electrical cabinet door. DO NOT change the parameters of the
components inside the cabinet. If changes are necessary, they must be performed by
professional personnel who have been trained by the equipment manufacturer, and
the parameters before the change should be recorded so that the original state can be
restored if necessary.
• DO NOT touch any live components inside the electrical cabinet while it is powered.
• The area around this machine should be kept dry, well-ventilated, and environmentally
controlled to keep the ambient temperature between 40 ℉ –95 ℉ (5 ℃ –35 ℃ ). For best
results, keep the temperature at 75 ℉ (25 ℃ ) or below. The ambient humidity should
remain between 70%.
• Do not handle the water pump or the water in which it is submerged while the pump
is attached to its power supply. Place it in water before connecting it to power and
disconnect it from power before removing it.
• Adjustment, maintenance, and repair of the electrical components of this machine 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.
