[Wiring Precautions]
● Mitsubishi programmable controllers must be installed in control panels. Connect the main power
supply to the power supply module in the control panel through a relay terminal block.
Wiring and replacement of a power supply module must be performed by qualified maintenance
personnel with knowledge of protection against electric shock.
For wiring methods, refer to the MELSEC-L CPU Module User's Manual (Hardware Design,
Maintenance and Inspection).
[Startup and Maintenance Precautions]
● Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction.
● Shut off the external power supply for the system in all phases before cleaning the module or
retightening the terminal block screw. Failure to do so may result in electric shock.
[Startup and Maintenance Precautions]
● Do not disassemble or modify the module. Doing so may cause failure, malfunction, injury, or a fire.
● Shut off the external power supply for the system in all phases before mounting or removing a
module. Failure to do so may cause the module to fail or malfunction.
● Tighten the terminal block screw within the specified torque range. Undertightening can cause drop
of the component or wire, short circuit, or malfunction. Overtightening can damage the screw and/or
module, resulting in drop, short circuit, or malfunction.
● Before handling the module, touch a conducting object such as a grounded metal to discharge the
static electricity from the human body. Failure to do so may cause the module to fail or malfunction.
