Mitsubishi Electric MELSENSOR MELSEC iQ-R MH11H01A0SNA User Manual page 5

[Design Precautions]
WARNING
● Provide safety measures such as a dual safety mechanism when the module is used for applications
that have the possibility of causing physical injury or serious damage.
● If a communication cable is disconnected, the network may be unstable, resulting in a communication
failure of multiple stations. Configure an interlock circuit in the program to ensure that the entire
system will always operate safely even if communications fail. Incorrect output or malfunction due to a
communication failure may result in an accident.
[Design Precautions]
CAUTION
● Do not use the laser displacement sensor outside of its specifications (such as ratings or
environments). Doing so may result in overheating or smoke.
● Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction
due to noise.
● Do not power off the programmable controller or reset the CPU module while the settings are being
written. Doing so will make the data in the flash ROM and SD memory card undefined. The values
need to be set in the buffer memory and written to the flash ROM and SD memory card again. Doing
so also may cause malfunction or failure of the module.
● Do not disassemble or modify this product. Doing so may cause failure, malfunction, injury, or a fire.
● Clamp cables securely with the terminal screws. Incomplete connections may cause overheating or
smoke.
● Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction.
● Do not open the covers on the back and the bottom of the product. Doing so may cause malfunction
or failure.
[Installation Precautions]
WARNING
● Shut off the external power supply (all phases) used in the system before mounting or removing the
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.
[Installation Precautions]
CAUTION
● Use this product in an environment that meets the general specifications in this manual. Failure to do
so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.
● When using the programmable controller in an environment of frequent vibrations, fix the module with
a screw.
● Do not directly touch any conductive parts of connectors on the modules. Doing so can cause
malfunction or failure of the module.
