**Varistors (ZNR Surge Absorber)** 

c 

## **- Handling Precautions  (D type / E, E S1 series)** 

## **1. Safety precautions** 

In case that a Varistors (ZNR Surge Absorber) (hereafter referred to as the ZNR, or product name) is used, if an abnormality takes place because of peripheral conditions of the ZNR(material, environments, power source conditions, circuit conditions, etc. in equipment design), fire, electric shock, burn, or product failure may be occur.  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. 

## **2. Precautions to be strictly observed** 

## **2.1 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. 

## **2.2 To avoid accidents due to unexpected phenomena, take the following measures** 

- ・ In the event of fracture of the ZNR, its pieces may scatter ; hence, put the case or cover of the set product in place. 

- ・ Do not install the ZNR near combustible substances(polyvinyl chloride wires, resin moldings, etc.). If it is difficult to do, install a nonflammable cover. 

- ・ Across-the-line use 

When the ZNR is used across a line, put a current fuse in series with the ZNR(Refer to Item 3.1-1). (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. 

- **2.3  If ZNR is shorted out and happen smoke or ignition, please cut provided current to ZNR immediately.** 

## **3. Application notes** 

## **3.1  Pay attention to the following items to avoid the shortened life and failure of the ZNR** 

## **3.1-1 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. 

   - ① Across-the-line use 

      - Use the part numbers marked with * in Table 1 if the power supply voltage is expected to rise temporarily due to load unbalance in a single wiring load in the case of a single-phase three-wire, short-circuit accident between voltage line and neutral line, missing neutral line accident, or resonance at switch opening/closing in the case of capacitive load, etc. 

   - ② 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). 

- (4) Concerning current fuse 

   - ① Select the rated current of the ZNR and current fuse as follows. Finally, please be sure that there is no danger if the ZNR mounted on the equipment breaks. The following fuse selection examples are for reference only and may vary depending on the operating circuit conditions. Therefore, use the fuses after confirming by testing, etc.
