Notes:
x
The AFP3631 is a voltage switching type. The AFP3636 is a free power supply type.
x
Use electrical wire that is thicker than 2 mm
2
to minimize the voltage drop.
x
Twist the electrical wire to minimize the effects of noise.
x
When using the AFP3631:
- When using 100 to 120 V AC, short the voltage switch terminal using the short circuiting bar included in
the package.
- When using 200 to 240 V AC, check that the space between the terminals is open.
<Recommended crimp>
x
Use M3.5 screws for the power supply terminal.
x
Crimping is recommended for all terminal wiring.
x
The following M3.5 screw terminals are recommended for wiring use.
7.2 mm/0.283 in.
or less
3.7 to 4.3 dia.
Fork type Round type
7.2 mm/0.283 in.
or less
J Power supply lines
x
The power supply lines for the FP3 or FP10S, I/O devices and motorized devices should be isolated as shown below.
x
Design the power supply lines so that the power for master and expansion backplanes can be turned ON and OFF at
the same time.
x
Use twisted pair cable with 2 mm
2
or larger conductors as the power supply lines.
x
Excessive noise and line voltage fluctuations can result in FP3 or FP10S CPU misoperation or in system shutdown.
To prevent accidents caused by noise and line voltage fluctuations, be sure to employ countermeasures (such as use
of an insulated transformer, etc.) when wiring the power supply lines.
Example:
Breaker

Momentary power drop
x
The FP3 and FP10S are not influenced by momentary power drops (less than 10 ms.)
