Precautions
• Use extension cable so that the overall extension length can be
within 13.2m (43.31 ft.).
• Do not install the extension cable together with the main circuit
(high voltage and high current) line or bring them close to each
other.
Keep a distance of 100mm (3.94 inch) or more between them.
• Set the number of extension stages so that the number is not
duplicated with another.
• Connect the extension cable from OUT of the extension cable
connector on the base unit to IN of the extension base unit on
the next stage.
• If the number of mounted modules exceeds the maximum
number of mountable I/O modules, an error "SP.UNIT LAY
ERR." (error code: 2124) occurs.
