1.5.1 Wiring Precautions
(1)If noise enters the IJ printer from the outside, there is the danger of erroneous operation
or trouble.
To improve noise resistance, perform wiring work as follows:
Separate the power cable to the IJ printer from other power lines for powering use
(especially, power line for a speed control inverter, etc.).
Wiring the power cable through a separate duct is even better.
Do not bundle input/output (I/O) signal wiring together with other power lines. Wire
them independently instead.
Electrically isolate the print target detector, print head, stand, and IJ printer body from
other machinery and equipment (conveyor, etc.).
Separate the print target detector wiring from other power lines.
Perform that all electrical wiring, connections and grounding comply with applicable
cords.
(When erroneous operation was caused by noise, etc., use a dedicated ground.)

(2) Connection to the power supply
Use a suitable plug and always connect the power source to a protective ground.
In addition, arrange the receptacles near the IJ printer so that removal is easy.
