SAFETY PRECAUTIONS (Continued)
Grounding
● When welding, keep enough space between the IJ printer and the
welding work area to prevent the arc from starting a fire. Also, be
sure to insulate the print head and IJ printer frame to keep the
welding current from flowing to the control section of the printer,
and to make a separate ground connection for the printer.
Exercise caution to avoid electric shock and fire.
● Make sure the ground wire is properly connected to the ground
of the electrical outlet.
Failure to do so could result electrical shock or fire.
● If you wish to receive ink particles in a beaker, for a printing test for
example, use an electrically conductive beaker and connect the
beaker securely to the ground.
Do not let the tip of the printing head enter the beaker.
Ink particles used for printing are electrically charged. An ungrounded beaker has
a gradually rising charge, possibly catching on or causing a fire.
Cable handling
● Use an AC voltage of 100 to120 V or 200 to 240 V only and a power
frequency of 50 or 60 Hz only.
If the above requirements are not met, the electric parts may overheat and burn,
creating a risk of fire or electric shock.
● Use the power cable that is designated in this manual.
● Wire the power supply in accordance with this manual.
