4.2.1 Wiring of Power Supply
Pin layout of power supply unit (FP2−PSA1 is used for the example below.)
Ground terminal
Power supply terminals
Supplies 100 to 120V AC.
Grounding
Use separate systems for the power
devices and the input devices.
Use 2mm
2
(AWG14) twisted pair
cable or larger.
Use an insulated transformer
when effects from noise are
great.
Breaker
ALARM output terminals
An alarm output can be
output when the ALARM
condition occurs
( section 4.6.3).
Power supply voltage
Verify that the power supply voltage connected to the power supply unit is within allow-
able limits.
Type Part number Rated input
voltage
Operating voltage rage Rated output current
AC type FP2−PSA1 100 to 120V AC 85 to 132V AC 2.5A
FP2−PSA2 200 to 240V AC 170 to 264V AC 2.5A
FP2−PSA3 100 to 240V AC 85 to 264V AC 5A
DC type FP2−PSD2 24V DC 20.4 to 31.2V DC 5A
Power supply wire
Use power supply wire that is thicker than 2mm
2
(AWG14) to minimize the voltage drop.
Pressure connection terminal
The following M3 pressure connection terminals are recommended for the wiring.
Fork type terminal Round type terminal
