Do not input a voltage of except 24VDC into it or trouble may occur on the
Q63P.
(2) Ensure that the earth terminals LG and FG are grounded.
(Ground resistance : 100
Since the LG terminal has a half of the input voltage, touching this terminal may
result in an electric shock.

a system error cannot be detected by the ERR terminal.
