• Connect the supplied "terminal resistors" in product at both ends of the CC-Link system. Connect the
terminal resistors between [DA] and [DB].
• Connect the shield wires of a Ver.1.10-compatible CC-Link dedicated cable to the SLD terminal in each
module through the FG terminal. Then ground the cables at both ends with a class D grounding (grounding
resistance: 100  or less). The SLD and FG terminals are connected inside.
• For the terminal processing of when connecting the Ver.1.10-compatible CC-Link dedicated cable to the
terminal block, do not unfasten the DA/DB/DG cable (three wires in one cable) or remove the sheath more
than necessary. (For cables with fillers, cut them using a tool.)
