[Installation Precautions]
● Use the programmable controller in an environment that meets the general specifications in the
MELSEC-L CPU Module User's Manual (Hardware Design, Maintenance and Inspection). Failure to
do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.
● To interconnect modules, engage the respective connectors and securely lock the module joint levers
until they click. Incorrect interconnection may cause malfunction, failure, or drop of the module.
● Do not directly touch any conductive parts and electronic components of the module. Doing so can
cause malfunction or failure of the module.
● Securely connect an extension cable to the connectors of a branch module and an extension module.
After connections, check that the cable is inserted completely. Poor contact may cause malfunction.
● When using an SD memory card, fully insert it into the SD memory card slot. Check that it is inserted
completely. Poor contact may cause malfunction.
● Do not directly touch any conductive parts and electronic components of the module or SD memory
card. Doing so can cause malfunction or failure of the module.
[Wiring Precautions]
● 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.
● After installation and wiring, attach the included terminal cover to the module before turning it on for
operation. Failure to do so may result in electric shock.
