2 SYSTEM CONFIGURATION
(1) The Q61P-A1 is dedicated for inputting a voltage of 100VAC.
(2) The Q63P is dedicated for inputting a voltage of 24VDC.
(3) Q64P automatically switches the input range 100/200VAC.
(4) Ensure that the earth terminals LG and FG are grounded.
(5) When the Q61P-A1, Q61P-A2, Q61P, Q62P, Q63P or Q64P is loaded on the

Q61P-A1 Operates normally.
Power supply module does
not cause trouble.
Q61P-A2
CPU module cannot be
operated.
Do not input a voltage of except 24VDC into it or trouble may occur on the Q63P.
Therefore, it is not compatible with the intermediate voltage (133 to 169VAC).
The CPU module may not work normally if the above intermediate voltage is
applied.
(Ground resistance : 100
Since the LG terminal has a half of the input voltage, touching this terminal may
result in an electric shock.
