WARNING
● Shut off the external power supply for the system in all phases 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 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. Incorrect interconnection may cause malfunction, failure, or drop of the module.
● Tighten the screw within the specified torque range.
Undertightening can cause drop of the screw, short circuit or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
● Do not directly touch any conductive parts and electronic components of the module. Doing so can
cause malfunction or failure of the module.
