Use the module in an environment that meets the general specifications
contained in this manual. Using this module in an environment outside the
range of the general specifications could result in electric shock, fire,
erroneous operation, and damage to or deterioration of the product.
z
Do not install the control wires or communication cables together with the
main circuit or power wires.
Keep a distance of 100mm (3.94inch) or more between them.
Not doing so could result in malfunctions due to noise.
z
Do not directly touch the module's conductive parts.
Doing so may cause malfunctions or failure of the module.

Fix the module securely with a DIN rail or screws, and when using screws,
tighten them within the specified torque range.
Undertightening can cause a drop, short circuit or malfunction. Overtightening
