Wiring of the power
supply
Wire the external power supply to the T3 power supply module.
When using the expansion unit, supply the power simultaneously to
the basic and expansion units.
(1 ) Power conditions
Power voltage
85 to 132 Vac/170 to 264 Vac,
50/60 Hz (PS361)
20.4 to 28.8 Vdc (PS332)
Power consumption
80 VA or less (PS361)
(per one PS) sow or less (PS332)
Retentive power 10 ms or less
interruption
(2) Correctly set the voltage switch terminals of the PS361
according to the power voltage. (100 to 120 Vac: short,
200 to 240 Vac: open)
(3) Install an electrostatic shielded transformer or a noise filter if the
power contains noise. See the figure at the bottom.
(4) Use twisted-pair cables (1.25 mm^) as the power supply cable.
Keep the cable as far as possible from the I/O cables.
(5) If the expansion unit with a power supply module is used, the
power for the basic and expansion units should be supplied from
the same source. Apply power at the same time or in the order
of the expansion unit then the basic unit.
(6) If a CVCF or UPS supplies power to the T3, observe waveforms
of the power supply; the peak voltage must be more than 130V
for the 100 to 120 Vac setting or 260V for the 200 to 240 Vac
setting.
