The precautions for this product are described below, understand the content thoroughly before usage. For more questions, contact us. If there's any uncertainty/doubt/products safety items, please contact us. When a dogma shall be occurred about safety for this products, be sure to inform us rapidly, operate your technical examination. 1. Precautions to be strictly observed 1.1 Confirmation of performance ratings Use the ZNR within its rated range of performance such as the Max. allowable voltage, withstanding surge current, withstanding energy, impulse life(surge life), average pulse power, and operating temperature range. If used outside the range, the ZNR can be degrade and have element fracture, which may result in smoking and ignition. 1.2 To avoid accidents due to unexpected phenomena, take the following measures 1) In the event of fracture of the ZNR, its pieces may scatter ; hence, put the case or cover of the set product in place. 2) Do not install the ZNR near combustible substances(polyvinyl chloride wires, resin moldings, etc.). If it is difficult to do, install a nonflammable cover. 3) Across-the-line use When the ZNR is used across a line, put a current fuse in series with the ZNR(Refer to Item 2.1.1). (4) . 4) Use between line to ground (1) If the case that the ZNR is used between a line to the ground, the short-circuit of the ZNR may not blow the current fuse because of grounding resistance, which may cause smoking and ignition of the ZNR’s exterior resin. As the measure against it, install an earth leakage breaker on the power supply side of the ZNR position. If no earth leakage breaker is installed, use a thermal fuse together wth a current fuse in series. (Refer to Table 1.) (2) If the case that the ZNR is used between a live part to metal case, an electric shock may develop at a shortcircuit of the ZNR ; hence, ground the metal case to the ground or keep it from the human body. 1.3 If ZNR is shorted out and happen smoke or ignition, please cut provided current to ZNR immediately. 2. Application notes 2.1 Pay attention to the following items to avoid the shortened life and failure of the ZNR 1) Circuit conditions (1) Select a ZNR of which the maximum voltage including fluctuations in source voltage allows for the maximum permissible circuit voltage. (Refer to Table 1.) (2) In cases that surges are intermittently applied at short intervals(for example, in case that the voltage of the noise simulator test is implemented etc.), do not let them exceed the ZNR’s rated power. (3) Select a ZNR recommended in Table 1. Across-the-line use If possible, use a Part No. marked with * in case of voltage temporarily rises load unbalance of separately-wired loads, short between hot and neutral-line, open of neutral line in single-phase-three-wired system, and due to resonance at switching for a capacitive, inductive load. 14-Dec-20 Varistors (ZNR Surge Absorber) Used between line to ground Use a different Part No. from “Across-the-line use” as table 1, because of raising voltage in case of “Line to Ground Fault”. Use a Part No. marked with ** in table 1, in case of the insulation resistance test(500 VDC) for equipment. When using a Part of the varistor voltage that the insulation efficiency examination can not be cleared, there is a case where the surge absorber can be done by removing it from the circuit depending on the circuit condition(Refer examination of Japan Domestic Safety Regulations). Use a Part No. marked with *** in table 1, in case of the withstanding voltage test (1000 VAC or 1200 VAC) for equipment. (4) Concerning current fuse We recommend selecting a ZNR and the rated current of a current fuse as follows. Finally, please be sure that there is no danger if the ZNR mounted on the equipment breaks. ●Type D, Series V Standard ERZV05D□□□ ERZV07D□□□ ERZV09D□□□ ERZV10D□□□ ERZV14D□□□ ERZV20D□□□ Part No. Fuse rated 10 A max. 10 A max. 3 A max. 5 A max. 7 A max. 7 A max. current ◆ Fuses shall use rated voltages ap pro pri ate for circuits. ●Type SMD, Series VF Standard ERZVF□M□□□ Part No. Fuse rated 5 A max. current ◆ Fuses shall use rated voltages ap pro pri ate for circuits. ◆ Concerning HF series, please confirm adjusted to load dump surge and protection cooperation.

ZNR (6) On use for equipment The catalog guarantees the quality as individual component. Before you use the products, please make sure to check and evaluate the products in the circumstance where they are installed in your product. 2) Operating environments (1) The ZNR is designed to be used indoors. Do not use it exposed outdoors. (2) Do not use the ZNR in places exposed to temperatures beyond the operating temperature range, such as places exposed to sunlight and vicinities of heating equipment. (3) Do not use the ZNR in places exposed to high temperatures and high humidity, such as places exposed directly to rain, wind, dew condensation, and vapor. (4) Do not use the ZNR in dusty and salinity environment and atmospheres polluted by corrosive gases, in liquids such as water, oil, chemical, organic solvent. 3) Processing conditions (1) Do not wash the ZNR by such solvents(thinner, acetone, etc.) as its exterior resin deteriorates. (2) Do not apply a strong vibration or shock (by falling, etc.) to the ZNR, cracking to its exterior resin and element may occur. (3) When coating the ZNR with resin(including molding), do not use such resin. (4) Do not bend the ZNR type D lead wires at the position close to its ZNR type D exterior resin, or apply external force to the position. (5) When soldering the ZNR lead wires, follow the recommended conditions and do not melt the solder and insulating materials constituting the ZNR. 14-Dec-20 Varistors (ZNR Surge Absorber) Soldering Method 260 10 260 10 Flow soldering Type D Flow soldering SMD Type Reflow soldering Attention Item Recommended Condition °C, within seconds. °C, within seconds.
