[Installation Precautions]
CAUTION
z
Use the programmable controller in an environment that meets the general
specifications in this manual.
Failure to do so may result in electric shock, fire, malfunction, or damage to
or deterioration of the product.
z
For protection of the switches, do not remove the cushioning material before
installation.
z
Securely fix the module with a DIN rail or mounting screws.
Tighten the screws 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.
z
Do not directly touch any conductive part of the module.
Doing so can cause malfunction or failure of the module.
[Wiring Precautions]
CAUTION
z
Shut off the external power supply for the system in all phases before wiring.
Failure to do so may result in damage to the product.
z
Ground the FG and FG1 terminals to the protective ground conductor
dedicated to the programmable controller.
Failure to do so may result in malfunction.
z
Tighten any unused terminal screws within the specified torque range (42 to
50N
x
cm).
Failure to do so may cause a short circuit due to contact with a solderless
terminal.
z
Use applicable solderless terminals and tighten them within the specified
torque range.
If any spade solderless terminal is used, it may be disconnected when the
terminal screw comes loose, resulting in failure.
z
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.
z
Tighten the terminal screw within the specified torque range.
Undertightening can cause short circuit or malfunction.
Overtightening can damage the screw and/or module, resulting in drop,
short circuit, or malfunction.
z
Prevent foreign matter such as dust or wire chips from entering the module.
Such foreign matter can cause a fire, failure, or malfunction.
