RoHS＜ Safety precautions for EMI filters＞

Attached document

Please be sure to read the following precautions before using this product in order to ensure its safe operation.

！

Ignoring the precautions below can result in death or serious injury.

1. Please do not touch the terminal or insert the electric wire, metal bar, or any other conductive materials into the punched holeor the case opening of EMI filter during its operation. It may cause electric shock and fire.
2. Make sure that EMI filter is completely discharged after being powered off before starting wiring work or inspection. The electricalcharge in the mounted capacitor won’t be discharged immediately after EMI filter is powered off, and may cause electric shock.
3. EMI filter must be securely grounded through its ground terminal or metal case body. Failure to do so may cause electric shock
or affect the performance of EMI filter. The ground wire should be short with its cross section more than or equal to 3.5 mm2.
4. Please do not dismantle, modify or repair EMI filter. It may cause fire, electric shock, and resulting injury.

！

Ignoring the precautions below can increase the risk of serious injury or fire.

1. Do not use EMI filter under the following conditions. The filter heated by applied overcurrent may result in its damage,deterioration or, fire.
* Applying current and/or voltage over rated value.
* Use of EMI filter for DC in AC circuit design.
* Use of I/O cable below rating.
* Use of AC other than utility frequency (50 Hz or 60 Hz).
2. Alternative current flows in mounted capacitor of EMI filter during its operation. Therefore, insufficient capacitance of circuit
breaker or transformer, connected to input side of EMI filter, may result in heating and fire. Please contact us for the specificvalue of alternative current. In addition, mounted capacitor may fume and burn when high frequency voltage is applied. If peak
to peak value of electrical surge and ripple voltage (DC voltage plus AC peak to peak value) exceed the rated voltage of EMI filter,
Please consult with us.
3. For installation of EMI filter to output side of inverter etc., please use the filter designed for output side installation.
Installation of EMI filter designed for input side to output side of inverter etc. may result in heating of the filter.
4. Please assure the connection of EMI filter with input and output cables using the torque wrench
Outside nut:or torque driver to control the torque. Insufficient tightening may result in heating and fire
Tighten with setof the filter.

5. Please do not rotate the inside nut when connecting with the bolt terminal (Figure 1.).
6. EMI filter equipped with terminal block (Figure 2.) should be connected, using crimp
terminal (stacking of crimp terminals allowed up to two). For any other mean ofconnection, please consult with our sales representative.
Connected with7. Please do not close the hole on the case with the punching metal structure. Closingcrimp terminal.
the hole will obstruct heat radiation of EMI filter, causing internal temperature rise,degradation, and fire.

back-to-back.
Installation on combustible material may causes fire.

9. Operation under the following environmental conditions bellow may cause EMI filter to(stacked terminals)
deteriorate, overheated due to its component failure, and fire.
* Corrosive (Cl2, NH3, SOx, NOx, etc.), volatile, or flammable gas environment* Exposed to (salt) water, oil or, fats
* Dusty* Vacuumed, decompressed, or pressurized environment*Outside* Nearby some flammable materials* Out of specified temperature range, relative humidity over 90%, condensation * Out of specified vibration condition
10. Turn off the power supply of EMI filter immediately upon observing abnormal phenomena, such as "fume", "odor", "unusual sound",and "overheating of enclosure surface". Failure to do so may cause fire.

！

Ignoring the precautions below can increase the risk of injury or material damage.

1. Upon placing EMI filter on desk or shelf, take measures to its drop to prevent product damage and injury.
2. For EMI filter weighed over 20kg, carry it with 2 persons to prevent injury. Do not grab on terminal block or bolt terminal tocarry EMI filter, or terminal may be broken off.
3. Connect EMI filter’s “IN or LINE” terminal to power supply side, “OUT or LOAD” terminal to supplying equipment side.
Installation of EMI filter in opposite direction will reduce its noise attenuation ability.
4. Keep EMI filters under the following conditions below.
Temperature
Relative humidity
Environment-20～60℃

0～60％

no condensation or steam

No direct sun light, minor dust and humidity alteration, No corrosive gas

5. Please include fail safe function to circuit design installing EMI filter. For use of EMI filter where failure or malfunction
could directly causes loss of life, damage of human or property, please consult with our sales representative beforehand.
6. For specific use of EMI filter such as aviation, aerospace, undersea, power plant control, transportation control, automobile,or any other use that requires extremely high reliability or other special uses, please consult with our sales representative
beforehand.
7. We take no responsibility for EMI filter’s malfunction or failure from operation under out of spec conditions.
8. Values on product specifications are for reference only. Please contract purchase/delivery specifications.
9. Under Foreign Exchange and Foreign Control Trade Law, upon exporting product (or information) comes under restricted freight(or labor) the permission of Japanese government may be required.
Problem that occurred without obeying 23 articles of safety precautions above, doesn't correspond to the product liability
prescribed by Product Liability Law (Act No.85 of July 1, 1994) Article 3.
