Electrical Safety Instructions - Omtech SH-G1060 User Manual

1 Safety Information
• ONLY use this engraver if its automatic shutoffs are working properly. When you first get
this engraver and if you subsequently notice any problems, test them (see below) before
undertaking any other work. Do not continue use if the shutoffs do not occur. Turn off the
device and contact customer service or your repair service. Never disable these shutoffs.
• DO NOT ever under ANY circumstances use this laser engraver if the water cooling system is
not working properly. Always activate the water cooling system and visually confirm that water
is flowing through the entire system before turning on the laser tube. Do not use ice water or
water that has become hotter than 100°F (38°C). For best results, keep it between 60–70°F
(15–21°C). Replace heated water or add sealed bottles of frozen water to cool it, while never
allowing the system to run without water or allowing the water to become colder than 50°F
(10°C). Immediately stop use if the water cooling system malfunctions.
• DO NOT use generic coolant or antifreeze in your cooling water, as they may leave corrosive
residues and solidify inside your hoses and piping, causing malfunctions and even explosions.
Use custom laser-safe formulations or use and store your engraver in a climate-controlled area.
• DO NOT leave potentially combustible, flammable, explosive, or corrosive materials nearby
where they could be exposed to the direct or reflected laser beam.
• DO NOT use or leave sensitive EMI equipment nearby. Ensure the area around the laser is free
of strong electromagnetic interference during any use.
• ONLY use this machine for working the materials described in the Material Safety section of
this manual. The laser settings and engraving process must be properly adjusted for specific
materials.
• Ensure the area is kept free of other airborne pollutants, as these might pose a similar risk of
reflection, combustion, etc.

1.5 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 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 below. The ambient humidity should not
exceed 70%.
