4.2 Wiring the Power Supply
4.2.1 Common Precautions
To avoid the influence of noises
Use a low noise power supply.
The inherent noise resistance is sufficient for the noise superimposed on the power wires,
however, the noise can be attenuated further by using the isolation transformer.
Also, twist the power supply cables to minimize adverse effects from noise.
Keep the power supply wiring separate
Wiring to the CPU unit, input devices, and power equipment should have separate wiring
systems.
Measures regarding power supply sequence (start up sequence)
Have the power supply se
quence such that the power supply of PLC turns off before
the power supply for input and output.
If the input/output power supplies are turned off before the power PLC, the CPU unit will
detect the input fluctuations and may begin an unscheduled operation.
