1:1 isolation
transformer
Screw (4 mm head with
selfraising pressure plate)
Voltage selector
Short: 100 to 120 VAC
Open: 200 to 240 VAC
Short-circuit these termi-
nals with the shorting
bracket supplied as an
accessory to select 100
to 120 VAC supply volt-
age. For 200 to 240 VAC
leave them open.
Isolation transformer
•
Noise between the PC
and ground can be sig-
nificantly reduced by
connecting a 1-to-1 iso-
lation transformer. Do
not ground the secon-
dary coil of the trans-
former.
Power line
•
Use AWG 14 twisted-
pair cable (cross-sec-
tional area: 2 mm
2
min.)
Breaker
AC power source
•
Supply 100 to 120
or 200 to 240 VAC
•
Keep voltage fluc-
tuations within the
specified range (refer
to
Appendix B Speci-
fications)
Voltage selector
Short: 100 to 120 VAC
Open: 200 to 240 VAC
Short-circuit these terminals
with the shorting bracket
supplied as an accessory to
select 100 to 120 VAC sup-
ply voltage. For 200 to 240
VAC, leave them open.
Screw (4 mm head with
selfraising pressure plate)
3G2A5-PS221-E/223-E
3G2A5-PS222-E
8.6 mm max.
Be sure to use a wire of at least 1.25 mm
2
in
thickness.
Use M4 screws for tightening crimp termi-
nals. Use ring crimp terminals for wiring. Do
not connect bare stranded wires directly to
terminal blocks.
Caution
Tighten the screws on the terminal block of the AC
Power Supply Unit to a torque of 1.2 N
S
m. Loose
screws may result in burning or malfunction.
