2.5 Wiring of the power supply
Wire the external power supply to model 3000 power supply module in the following
manner.
When using expansion units, arrange for power to be supplied simultaneously to the
basic unit and the expansion units (or to the expansion units before the basic unit).
(1) Power conditions
Rated voltage
Retentive power interruption
(2) Install an electrostatic shielded transformer or a noise filter if the power contains
noise. See figurer at the bottom.
(3) Use twisted-pair cables (1.25mm
far 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 model 3000, observe waveforms of the power
supply; the peak voltage must be more than 130V for the 100VAC range or 260V
for the 200VAC range.
