[Wiring Precautions]
CAUTION
Individually ground the FG and LG terminals of the programmable controller with a ground
resistance of 100 or less.
Failure to do so may result in electric shock or malfunction.
Use a solderless terminal with insulation sleeve for wiring of a terminal block.
Use up to two solderless terminals for a single terminal.
Use applicable solderless terminals and tighten them within the specified torque range.
If any spade solderless terminal is used, it may be disconnected when a terminal block screw comes
loose, resulting in failure.
Check the rated voltage and terminal layout before wiring to the module, and connect the cables
correctly.
Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire or
failure.
Tighten the terminal block mounting screws, terminal screws, and module fixing screws within the
specified torque range.
Undertightening of the terminal block mounting screws or terminal screws can cause short circuit,
fire, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
Undertightening of the module fixing screws can cause drop of the module.
Overtightening can damage the screw and/or module, resulting in drop.
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 the film during wiring.
Remove it for heat dissipation before system operation.
