 Precautions

● Do not use this product to parts feeder of piezoelectric method

● Never use this product in a place where there are ignitable materials or
inflammables
There is a risk of an explosion or a fire

● Do not use this product in a place where there are a lot of dust or moisture
This product is not dustproof or waterproof. Particularly, a separate measure
for protection is required in a place where there are a lot of metal powders.

● Do not turn on/off input power frequently.

It may cause a failure by remarkably deteriorating internal electronic
components. Particularly, avoid using the on/off control method on the parts
feeder by intermitting the input power of this product with a magnetic switch
(Relay)(It is necessary to use an external signal control method using an EXS
terminal).

● Do not turn on/off this product in the output part.

It is because the controller is damaged when the driving part is
operated/stopped by inserting the magnetic switch (RELAY) in the output part(It
is necessary to use an external signal control method using an EXS terminal).

● Do not perform welding process on the FEEDER in the state that the driving part
is connected to the controller.
The leak current on welding may damage the controller.

● Do not use the output of the PWM inverter as an input power of this product.
It may cause damage of this product.

● Use this product within rated voltage and rated current of input/output power.

● Do not disassemble, repair and convert this product carelessly.

It may cause damage or malfunction of this product.

● Perform wiring work when power is turned off.

There is a possibility of product damage or an electric shock.

● Connect the ground terminal of the input/output power to the ground necessarily.
It prevents the electric shock in the leakage of electricity and reduce power
noise.

As this product is designed for AC100V~240V and FREE - VOLTAGE, it can be

used for input power without mechanical or electrical setting change.

<Notice>
1. When the cover is taken off, isolate the input power necessarily.
2. (FG:Frame Ground) for input and output power terminals shall be connected
necessarily for the prevention of electric short and stable operation.

◎ If RUN LED lights on, but Parts Feeder is not vibrated, please check followings.
① Is voltage set to be "0" or too low?
→ Set voltage properly.
Adjust with VOLTAGE VR.
② Is frequency deviated from resonant frequency too much?
→ Change frequency to set frequency where strong vibration can be felt.
Adjust with FRQM and FRQS VR.
③ Is it in error status?
→ Take countermeasures against error as per the contents guided by TRIP LED.
