[Installation Precautions]
CAUTION
● Use the module in an environment that complies with the general specifications described in the
user's manual of the CPU module used. Failure to do so can cause electric shock, fire, malfunction,
damage, or deterioration of the module.
● Do not directly touch the conductive part of the module. Failure to do so can cause malfunction or
failure of the module.
● Fully mount the antenna cable to the module connector. Insufficient contact can cause malfunction of
the module.
● To mount a module, place the concave part(s) located at the bottom onto the guide(s) of the base unit,
and push in the module until the hook(s) located at the top snaps into place. Incorrect mounting can
cause malfunction, failure, and drop of the module.
● When using the programmable controller in an environment with frequent vibrations, fix the module
with screws.
● Securely fix the module with mounting screws. Tighten the screws within the specified torque range.
Undertightening can cause insufficient contact or malfunction of the module. Overtightening can
cause damage of the screws and/or circuit board, resulting in short-circuit or malfunction of the
module.
● Do not drop the case or expose the case to strong impact. Doing so can cause malfunction or failure
of the module.
[Wiring Precautions]
WARNING
● Shut off all phases of the external power supply used in the system before installing or removing the
module. Failure to do so can cause damage or malfunction of the module or electric shock.
[Wiring Precautions]
CAUTION
● Individually ground the FG and LG terminals of the programmable controller with ground resistance of
100Ω or less. Failure to do so can cause electric shock or malfunction of the module.
● Check the rated voltage and signal layout before wiring to the module, and connect the cables
correctly. Connecting a power supply with a different voltage rating or incorrect wiring can cause fire
or failure.
● Connectors for external devices must be crimped or pressed with the tool specified by the
manufacturer, or must be correctly soldered. Incomplete connections can cause short circuit, fire, or
malfunction.
● Use applicable solderless terminals and tighten them within the specified torque range.
● Fully mount the amplifier/antenna cable to the module connector. After mounting, check for
separation. Insufficient contact can cause erroneous input and output.
● Place the amplifier/antenna cables and power cables connected to the module in a duct, or clamp
them. Failure to do so can cause movement or drift of cables, damage of the module or cables due to
careless pulling, or malfunction of the module due to insufficient cable contact.
