Startup And Maintenance Precautions - Mitsubishi Electric Q12DCCPU-V User Manual

[Startup and Maintenance Precautions]

Do not touch any terminal while power is on.
Doing so will cause electric shock.
Correctly connect the battery connector.
Do not charge, disassemble, heat, short-circuit, solder, or throw the battery into the fire.
Doing so will cause the battery to produce heat, explode, or ignite, resulting in injury and fire.
Shut off the external power supply for the system in all phases before cleaning the module or
retightening the terminal screws or module fixing screws.
Failure to do so may result in electric shock.
Undertightening the terminal screws can cause short circuit or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
For the following controls, configure an interlock circuit in the user program to ensure that the entire
system will always operate safely.
(1) Changing data of the running C Controller module from the development environment (personal
computer) connected
(2) Changing the operating status
( 3) Operation from the development environment (personal computer)
Especially, in the case of a control from an external device to a remote C Controller module,
immediate action cannot be taken for a problem on the C Controller module due to a communication
failure.
To prevent this, configure an interlock circuit in the user program, and determine corrective actions to
be taken between the external device and C Controller module in case of a communication failure.
