4.9 Wiring
This section provides the instructions for wiring the AJ65VBTCU-68ADVN/ADIN and its
wiring with external equipment.
4.9.1 Wiring precautions
To obtain maximum performance from the functions of AJ65VBTCU-68ADVN/ADIN
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-68ADVN/ADIN 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.
