4.2 Installation environment
Refer to the user's manual of the programmable controller CPU module
used.
Point
(1) Turn off the power supply to the applicable station before mounting or removing the
terminal block.
If the terminal block is mounted or removed without turning off the power supply to the
applicable station, correct data transmission cannot be guaranteed.
(2) Power off the system in advance when removing the terminating resistor to change the
system. If the terminating resistor is removed and mounted while the system is
energized, normal data transmission will not be guaranteed.
