order to discharge any static built-up.
The following precautions are necessary to ensure the general safety of the sys-
tem. Always heed these precautions.
• Fail-safe measures must be taken by the customer to ensure safety in the
event of incorrect, missing, or abnormal signals caused by broken signal lines,
momentary power interruptions, or other causes.
• The interlock circuits, limit circuits, and similar safety measures must be pro-
vided by the customer for external circuits (i.e., not in the Programmable Con-
troller).
• Do not touch the Expansion I/O Unit Connecting Cable while the power is
being supplied in order to prevent any malfunction due to static electricity.
