This section provides the instructions for wiring the AJ65VBTCU-68DAVN and its
wiring with external equipment.
To obtain maximum performance from the functions of AJ65VBTCU-68DAVN 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-68DAVN external output
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 programmable controller. Noises, surges, or conductivity may
affect the system.
(3) Place a one-point grounding on the programmable controller side for the shielded
line or shielded cable.
(4) Smoke and fire may occur when an overcurrent flows intermittently for a long
period of time. To avoid this, configure a safety circuit, such as an external fuse, to
protect the product.
