Power supply sequence
•
Make sure the power supply of the CPU turns off before the power supply
for input and output. If the power supply for input and output is turned off
first, the CPU will detect the input fluctuations and may begin an
unexpected operation.
•
Be sure to supply power to a CPU and an expansion unit from the same
power supply, and turn the power on and off simultaneously for both.
