4.6 Wiring of the power supply

(1) Power conditions

[Example]
Rated voltage
Power consumption
Retentive power interruption :10ms or less
Use a constant voltage transformer if power supply is unstable.
(2) Install an electrostatic shielded transformer or a noise filter if the power contains
noise. See the figure at the bottom.
(3) Use twisted-pair cables (1.25mm
as possible from I/O cables.
(4) If the expansion unit with a power supply module is used, the power of 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.
(5) If a CVCF or UPS supplies power to the model 2000, observe waveforms of the
power supply; the peak voltage must be more than 130V for the 100Vac range or
260Vac for the 200Vac range.
