(7) Prevent foreign matter such as dust or wire chips from entering the module.
Such foreign matter can cause a fire, failure, or malfunction.
(8) A protective film is attached to prevent foreign matter, such as wire chips, from
entering the module during wiring.
Do not remove this film until the wiring is complete.
Remove it for heat dissipation before system operation.
(9) Solderless terminals with insulation sleeve cannot be used for the terminal
block.
It is recommended to cover the connection part of the solderless terminal with a marking tube or an insulation
tube.
(10)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.

● Be sure to power off the station before installing or removing the terminal block.
If the terminal block is installed or removed without powering off the station, correct data transmission cannot be
guaranteed.
● Always power off the system in advance when installing or removing a terminating resistor to change the system. If the
terminating resistor is installed or removed while the system is energized, normal data transmission will not be
guaranteed.
