K. 12 and UL 497B Terms and current waveforms in accordance with: ITU-T Rec. K. 12; IEC 61643-21 and DIN 57845 / VDE0845 Packing Cautions and warnings ● Depending on the incorporation position,the surge arrester may have to be additionally secured by ● ● ● mechanical means. Surge arresters must not be operated directly in power supply networks. Surge arresters may become hot in case of longer periods of current stress(danger of burning). Damaged surge arresters must not be re-used. DG Elec. Please read Cautions and warnings and important notes at the end of this document. Issue 01/2017-05-17 Page 4 of 4
