(a) Be sure to ground the cable shield that is connected to the CC-Link module
close to the outlet of a control panel or to any of the CC-Link stations within
30cm from the module or stations.
The CC-Link dedicated cables are shielded cables. As shown in the illustration
below, remove a part of the outer sheath and ground it to the widest possible
area.
(b) Always use the specified CC-Link dedicated cable.
(c) Connect the CC-Link module and each CC-Link station to the FG line inside the
control panel with the FG terminals as shown below.

(d) Each power line connecting to the external power supply terminal or module
power supply terminal must be 30m (98.43 ft) or less.
(e) Install a noise filter to the external power supply. Use a noise filter with an
attenuation characteristic equivalent to that of the MA1206 (TDK-Lambda
Corporation). Note that a noise filter is not required when the module is used in
Zone A defined in EN61131-2.
(f) Keep the length of signal cables connected to the analog input terminals of the
following modules to 30m or less.
Wire cables connected to the external power supply and module power supply
terminal in the control panel where the module is installed.
• AJ65BT-64RD3
• AJ65BT-64RD4
• AJ65BT-68TD
(g) For the cable connected to the power supply terminal of the AJ65SBT-RPS or
AJ65BT-68TD, attach a ferrite core with an attenuation characteristic equivalent
to that of the ZCAT3035-1330 from TDK Corporation. Twist the cable around the
ferrite core by one as shown below.
