[Wiring Precautions]
Shut off the external power supply for the system in all phases before wiring.
Failure to do so may result in electric shock or damage to the product.
Ground the FG and LG terminals to the protective ground conductor
dedicated to the programmable controller.
Failure to do so may result in electric shock malfunction.
Check the rated voltage and terminal layout before wiring to the terminal
block for the external power supply, and connect the cable correctly.
Connecting a cable to power supply with a different voltage rating or
incorrect wiring may cause a fire or failure.
Tighten the terminal screw within the specified torque range.
Undertightening can cause drop of the screw, short circuit or malfunction.
Overtightening can damage the screw and/or module, resulting in drop,
short circuit, or malfunction.
Correctly solder coaxial cable connectors. Incomplete soldering may result in
malfunction.
Prevent foreign matter such as dust or wire chips from entering the module.
Such foreign matter can cause a fire, failure, or malfunction.
A protective film is attached to the top of the module to prevent foreign
matter, such as wire chips, from entering the module during wiring.
Do not remove this film during wiring.
Remove it for heat dissipation before system operation.
Place the cables in a duct or clamp them.
If not, dangling cable may swing or inadvertently be pulled, resulting in
damage to the module or cables or malfunction due to poor contact.
When disconnecting the communication and power cables from the module,
do not pull the cable by the cable part.
Loosen the screws of connector before disconnecting the cable.
When disconnecting a cable connected to a terminal block, loosen the
screws on the terminal block first before removing the cable.
Failure to do so may result in damage to the module or cable or malfunction
due to poor contact.
