[Installation Precautions]
Use the module in the environment that meets the general specifications contained in this
Manual.
Using the module outside the range of the general specifications may result in electric shock,
fire or malfunction, or may damage or degrade the module.
Securely fix the module to a DIN rail or with mounting screws, and securely tighten the mounting
screws within the specified torque range.
Undertightening can cause a drop or malfunction.
Overtightening can cause a drop or malfunction due to damage of the screws or module.
Do not touch the conducted area or electric parts of the module.
Doing so may cause module malfunction or breakdowns.
[Wiring Precautions]
Be sure to shut off all phases of the external power supply used by the system before installation
or wiring.
Not doing so can cause the product to be damaged or malfunction.
Always earth the FG terminal to the protective earth conductor.
Not doing so can cause a malfunction.
Be sure to tighten any unused terminal screws within a tightening torque range (42 to 50N . cm).
Failure to do so may cause a short circuit due to contact with a solderless terminal.
Use applicable solderless terminals and tighten them with the specified torque.
If any solderless spade terminal is used, it may be disconnected when the terminal screw comes
loose, resulting in failure.
Wire the module correctly after confirming the rated voltage and terminal layout of the product.
Not doing so can cause a fire or failure.
Tighten the terminal screws within the specified torque range.
Undertightening can cause a short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to damage of the screws or module.
Ensure that no foreign matter such as chips and wire-offcuts enter the module.
Foreign matter can cause a fire, failure or malfunction.
Be sure to fix the wires or cables by ducts or clamps when connecting them to the module.
Failure to do so may cause damage of the module or the cables due to accidental pull or
unintentional shifting of the cables, or malfunctions due to poor contact of the cable.
