Page 7: Safety Measures
Matters to Be Observed When Using This Product Matters to Be Observed When Using This Product (D-type : V series / SMD-type : HF・VF series) Safety measures An abnormal state for varistors (ZNR surge absorbers) of the D type/V series and SMD-Type/HF, VF Series (hereinafter the product or "the surge absorber") that results from a problem with service conditions (materials used, the surrounding environment, power conditions, circuit conditions, etc.) may cause a fire accident, electric shock accident, burn accident, or product failure. - Page 8 Matters to Be Observed When Using This Product Use environments and cleaning conditions ■ Do not use the surge absorber in an outdoor environment where the surge absorber is exposed to sunlight. ■ Do not use the surge absorber in which direct sunlight hits the surge absorber or near a heating element where the temperature of the surge absorber would rise above its working temperature.
- Page 9 Matters to Be Observed When Using This Product ■ Current fuse (1) Select a surge absorber and the rated current for a current fuse to be used in a manner shown in the following table. Confirm that no secondary accident arises when the surge absorber in an actual circuit breaks. Selected rated currents of current fuses shown in the following table are exemplary one and may vary depending on circuit conditions used.
