1.6 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 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.

The ambient humidity should not exceed 70%.
• DO NOT handle your 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 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, disconnected from its power supply, and fully cooled.
