- Page 5 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 6 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 7 * Use the rated voltage of the current fuse that corresponds to the circuit voltage of a circuit including the current fuse. * For the HF series surge absorber, select the rated current of the fuse after confirming the way the fuse handles a load dump surge and the protective coordination action it makes when the surge absorber is destroyed.
