DESIGN PRECAUTIONS
When a remote module fails, outputs may randomly turn ON or OFF, therefore, build an
external monitoring circuit that will protect from any input signals that could cause a serious
accident.
DESIGN PRECAUTIONS
• Do not bind control cables and connection cables to CC-Link/LT together with power
cables.
Keep control cables and connection cables to CC-Link/LT away from major circuits and
power cables by 100 mm (3.93") or more.
It may cause a malfunction due to noise interference.

-64CL-M in an environment status that any force is not directly applied on
connectors for CC-Link/LT interface and connection cables to CC-Link/LT.
If any force is applied, wire breakage and failure may occur.
