Precautions
This section describes wiring precautions.
(1) Precautions for handling the SSCNET III cable
• Do not step on the SSCNET III cable.
• When laying the SSCNET III cable, keep the minimum or a larger cable bend radius. If the bend radius is
smaller than the minimum cable bend radius, it may cause malfunctions due to characteristic degradation or
a wire break.
• When installing or removing the SSCNET III cable, hold the knob of the cable connector.
(2) Connecting the SSCNET III cable
• When connecting the SSCNET III cable to the head module, connect the SSCNET III cable to CNA and CNB
of the head module, holding the knob of the SSCNET III cable connector. Securely insert the cable until it
clicks.
• If the end faces of the SSCNET III cable are covered with dirt, optical transmission is interrupted and a
malfunction may occurs. Wipe the dirt with a nonwoven fabric. Do not use a solvent such as alcohol.
(3) Disconnecting the SSCNET III cable
• When disconnecting the SSCNET III cable, hold the knob of the SSCNET III cable connector then pull it out.
• After disconnecting the SSCNET III cable, put the cap, attached to the head module, to the head module.
• Cover the end faces with protection tubes for optical cord's end faces.
