1.5.1 Wiring Precautions
(1) If extraneous noise enters the printer, it may abnormally operate or become defective.
For increased noised immunity, observe the following precautions when making wiring
connections.
1 Ensure that the power supply cable connected to the printer is positioned away
from the other motive power supply lines (particularly the speed control inverter
power supply line).
For best results, they should be routed within respective ducts.
2 Do not bundle the interlock wiring together with the other motive power lines.
Be sure that they are routed separately.
3 Electrically insulate the print target detector, print head, stand, and printer main
body from the other mechanical devices (conveyors, etc.).
4 Ensure that the print target detector wiring is positioned away from the other
motive power supply lines.
5 Ensure that all electrical wiring, connections and grounding comply with
applicable codes. (A dedicated ground should be provided if erratic operations
are caused by noise or the like.)
(2) Connection to the power supply
The printer should be connected using a suitable plug and socket outlet which is
accessible and close to the equipment, so that power can be quickly disconnected.
