■Usage cautions
● Always mount fuse on the Live side of input for ensuring safety because the fuse is not
built-in the product.
Please select the fuse considering conditions such as steady current, inrush current,
and ambient temperature.
※Recommended parts: FIH 250V 1.6A～2.5A / NIPPON-SEISEN
When using a fuse having large rated current or high capacity input electrolytic condenser, by combining
another converter and input line and input electrolytic condenser, fuse may not blow off in the case of abnormality.
Do not combine high voltage line and fuse.
