5. PRECAUTIONS FOR WIRING CABLES

(1) Wire fiber-optic cables described in the following manual.
• CC-Link IE Controller Network Reference Manual
(2) For connecting fiber-optic cables to the unit, the bending radius of the
cables must be within the specified range.
For the details, check the specifications of the cables to be used.

the cable connector securely with the hands.

"click" sound.

phases of the external power supplies used in the system.
(7) Please wire IN/OUT of the connector for the cable correctly.
After wiring, perform a loop test or station-to-station test or others to
confirm if the setting and wiring of CC-Link IE communication unit have
been done properly.
