CAUTION
●
Do not install the control lines or communication cables together with the
main circuit lines or power cables. Keep a distance of 100mm or more
between them. Failure to do so may result in malfunction due to noise.
CAUTION
●
Use the module 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.
●
For protection of the switches, do not remove the cushioning material before
installation.
●
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.
●
Do not directly touch any conductive part of the module. Doing so can cause
malfunction or failure of the module.
WARNING
●
Shut off the external power supply for the system in all phases before wiring.
Failure to do so may result in malfunction or damage to the product.
CAUTION
●
Ground the FG terminal to the protective ground conductor dedicated to the
programmable controller. Failure to do so may result in electric shock or
malfunction.
●
Tighten any unused terminal screws within the specified torque range (0.42
to 0.50N•m). Failure to do so may cause a short circuit due to contact with a
solderless 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 the terminal screw comes loose, resulting in failure.
