[Design Precautions]
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.
● Select the external devices to be connected to the module by referring to the performance
specifications in this manual and considering the maximum inrush current. Connecting a device
exceeding the maximum inrush current may cause malfunction or failure of the module.
● During control of an inductive load such as a lamp, heater, or solenoid valve, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on.
Therefore, use a module that has a sufficient current rating.
[Installation Precautions]
WARNING
● Shut off the load power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.
[Installation Precautions]
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.
● Do not directly touch any conductive parts and electronic components of the module. Doing so can
cause malfunction or failure of the module.
● Securely fix the module with mounting screws. Failure to do so may cause the module to fail due to
increasing effects of vibrations.
● Securely connect the cable connectors. Poor contact may cause malfunction.
● After the first use of the product, do not connect/remove the connectors more than 50 times (IEC
61131-2/JIS B 3502 compliant). Exceeding the limit may cause malfunction.
[Wiring Precautions]
WARNING
● Shut off the load power supply (all phases) used in the system before wiring. Failure to do so may
result in electric shock or cause the module to fail or malfunction.
