Caution Warning
11. Transition wiring of ionizer
For transition wiring of ionizers, use a transition wiring cable for connection
between ionizers. Use a power supply cable for connection between ionizer
and power supply or external equipment. (Transition wiring is not possible with
the IZS40.) The number of ionizers that may be connected using transition
wiring varies depending on the power supply cable; the length of the transition
wiring cable; the use of external sensor(s) and/or models. Refer to the table
shown below “Connectable number of ionizers with transition wiring.”
The IZS41 and IZS42 can be connected in the same transition wiring, but
mixed wiring of the NPN and PNP I/O specifications is not possible.
Please contact SMC when connecting conditions other than specified in the
table below are applied.
It is recommended that the power supply used to operate the ionizers
have a current capacity twice that of the total current consumption of
the ionizers to be used. Power supply voltage should be from 24 to
26.4 VDC.
AC adapter must not be used when ionizer is used in a transition wiring.
When ionizers are connected with transition wiring, the same input
signal serves as input to all the ionizers. When a signal is output from at
least one ionizer in the connection, the signal will be output from the
power supply cable.
Connect the power supply cable to the “POWER” connector of the 1st
ionizer, and connect the “LINK” connector of the 1st ionizer to the
“POWER” connector of the 2nd ionizer with a transition wiring cable.
Follow the same procedure to connect subsequent ionizer(s) and after
with transition wiring cables.
2. Make sure to confirm the effect of static neutraliza-
tion after installation.
The effects vary depending on the ambient conditions, operating
conditions, etc. After installation, verify the effects of static neutralization.
3. When installing the IZS41 or IZS42 in proximity with
an ionizer which operates in DC mode, they should
be positioned at least 2 meters away from each other.
When using the IZS41 or IZS42 near the ionizer in DC mode,
keep clearance of at least 2 m between them.
The offset voltage may not be adjusted by the built-in sensor
due to the ions discharged from the DC mode ionizer.
Wiring / Piping
Warning
1. Before wiring, ensure that the power supply capacity is
enough and that the voltage is within the specification.
2. To maintain product performance, the power supply shall be
UL listed Class 2 certified by National Electric Code (NEC) or
evaluated as a limited power source provided by UL60950.
3. Ground the F.G. wire with 100
Ω
or less according to the
instructions in this catalog. An incomplete ground or no grounding
not only prevents the performance of the product from being
maintained, but may also cause failure or damage of the product,
or electric shock to the human body.
4. Be sure to turn off the power supply before wiring
(including insertion and removal of the connector).
5. To connect a feedback sensor or auto balance sensor
to the ionizer, use the cable included with the sensor.
Do not disassemble or modify the ionizer.
6. Ensure the safety of wiring and surrounding condi-
tions before supplying power.
7. Do not connect or disconnect the connectors (in-
cluding power source) while the power is supplied.
Otherwise, the ionizer may malfunction.
8. If the ionizer wiring and high power lines are routed
together, this product may malfunction due to noise.
Therefore, use a separate wiring route for this product.
9. Confirm that the wiring is correct before operation. Incor-
rect wiring will lead to product damage or malfunction.
10. Flush the piping before use. Before piping this
product, exercise caution to prevent particles, water
drops, or oil contents from entering the piping.
