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.
●
At power-on/off, a voltage may occur or a current may flow between output terminals for a moment. In
this case, start the control after analog outputs become stable.
WARNING
●
Shut off the external 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.
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.
●
After the first use of the product, do not connect/remove the extension module more than 50 times
(IEC 61131-2 compliant). Exceeding the limit may cause malfunction.
●
To connect an extension module to a main module, engage the respective connectors and securely
lock the module joint levers. Incorrect interconnection may cause malfunction, failure, or drop of the
extension module.
●
Securely connect the cable connectors. Poor contact may cause malfunction.
WARNING
●
Shut off the external 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.
CAUTION
●
Individually ground the FG terminal of the programmable controller with a ground resistance of 100
ohms or less. Failure to do so may result in electric shock or malfunction.
●
Tighten any unused terminal screws within the specified torque range. Undertightening can cause a
short circuit due to contact with a solderless terminal.
