4 SETUP AND PREPARATION BEFORE OPERATION
POINT
• On this unit, use the Ver. 1.10-compatible CC-Link dedicated cable (FANC-
110SBH, CS-110, FA-CBL200PSBH).
You cannot use the Ver. 1.10-compatible CC-Link dedicated cables of other than
the above types, CC-Link dedicated cables and CC-Link dedicated, high-
performance cables.
• The shield cable of the CC-Link dedicated cable should be connected to "SLD" in
each module, and both ends should be grounded through "FG".
SLD and FG are connected inside the module.
4.8 Wiring
This section provides the instructions for wiring the AJ65VBTCU-68ADV/ADI and its
wiring with external equipment.
4.8.1 Wiring precautions
To obtain maximum performance from the functions of AJ65VBTCU-68ADV/ADI and
improve the system reliability, an external wiring with high durability against noise is
required.
The precautions when performing external wiring are as follows:
(1) Use separate cables for the AC and AJ65VBTCU-68ADV/ADI external input
signals, in order not to be affected by the AC side surge or conductivity.
(2) Do not bundle or place with load carrying wires other than the main circuit line,
high voltage line or PLC. Noises, surges, or conductivity may affect the system.
(3) Place a one-point grounding on the PLC side for the shielded line or shielded
cable. However, depending on the external noise conditions, it may be better have
a grounding externally.
