[Wiring Precautions]
● When disconnecting the cable from the module, do not pull the cable by the cable part.
For the cable with connector, hold the connector part of the cable.
For the cable connected to the terminal block, loosen the terminal screw.
Pulling the cable connected to the module may result in malfunction or damage to the module or
cable.
● Mitsubishi Electric 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 maintenance personnel who
is familiar with protection against electric shock. For wiring methods, refer to the QCPU 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.
● Correctly connect the battery connector.
Do not charge, disassemble, heat, short-circuit, solder, or throw the battery into the fire. Also, do not
expose it to liquid or strong shock.
Doing so will cause the battery to produce heat, explode, ignite, or leak, resulting in injury and fire.
● Shut off the external power supply (all phases) used in the system before cleaning the module or
retightening the terminal screws, connector screws, or module fixing screws.
Failure to do so may result in electric shock or cause the module to fail or malfunction.
[Startup and Maintenance Precautions]
● Before performing online operations (especially, program modification, forced output, and operation
status change) for the running CPU module from the peripheral connected, read relevant manuals
carefully and ensure the safety.
Improper operation may damage machines or cause accidents.
● Do not disassemble or modify the modules.
Doing so may cause failure, malfunction, injury, or a fire.
● Use any radio communication device such as a cellular phone or PHS (Personal Handy-phone
System) more than 25cm away in all directions from the programmable controller.
Failure to do so may cause malfunction.
