注意事項Matters needing attention
1、 磁保持繼電器出廠狀態為觸點閉合狀態（復位狀態），但因運輸或繼電器安裝時受到沖擊等因素的影響，可能會改變狀態，因此在使用前（電源接入時）有必要采取措施重新使其復位。
Magnetic latching relay factory condition for contact closure state,but because carry or installed when subjected to impact,may change state,therefore before use to make its reset.
2、 為了確保磁保持繼電器可靠動作，施加到線圈上的激勵電壓須達到額定值，且脈沖寬度設置須達到動作時間的3倍以上。
Ln order to ensure the reliability of relay coil voltage,must reaeh value,the pulse width must be 3 times more time.
3、 不帶軟銅編織線的磁保持繼電器，負載引出腳不能錫焊，不能隨意扳動，且不能同時剛性固定兩個引出腳。
Not with braided line relay,the load pin can not solder,not arbitrarily wrenched,two pins and rigid fixation
4、 磁保持繼電器是有極性區分的，如果用戶需要的極性與本資料不符，應在訂貨時特別提出。
Magnetic latching relay is polar differentiation,and if the user needs to polarity and the data is inconsistent,should be in order when the special offers.
5、 繼電器入廠檢查及使用中應輕拿輕放，防止跌落影響參數。入廠作破壞性檢查的產品要與正常產品嚴格區分標識，不得裝機使用。
Relay incoming inspection should be light-light,do the destructive test of products must be consistent with normal goods isolated and labeled,shall not be used.
