Wiring Procedure

Wiring to terminal block
This section describes wiring to the terminal block.
Connect a Ver.1.10-compatible CC-Link dedicated cable as shown below.
Ver.1.10-compatible CC-Link dedicated cable
DA line (blue)
DB line (white)
DG line (yellow)
Shield wire
• Connect the terminating resistors between the DA and DB terminals.
• Connect the shield wires of a Ver.1.10 compatible CC-Link dedicated cable to the SLD terminal through the
FG terminal. Then ground the cables at both ends with a ground resistance of 100 ohms 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.)

• No restrictions apply to the connection order of a master/local module. (The cables need not be connected
in the order of station number.)
• The star topology cannot be used. Note, however, that the T-branch connection can be used. ( Page 34
