注：單相導軌式電能表應安裝(zhuang)在(zai)室內(nei)通風干(gan)燥(zao)的地方，采用(yong) 35mm 標準導軌方式安裝(zhuang)。安裝(zhuang)接(jie)(jie)線(xian)時應 按(an)照電能表側面的接(jie)(jie)線(xian)圖進(jin)行接(jie)(jie)線(xian)，最好用(yong)銅接(jie)(jie)線(xian)頭(tou)接(jie)(jie)入，接(jie)(jie)線(xian)力矩不應大于(yu) 4.0N·m。

6.1 輔(fu)助電源(yuan)故 障 故障表(biao)(biao)現(xian)：儀(yi)表(biao)(biao)通電后(hou)閃(shan)爍、不亮等。 故障排除：1.檢查輔(fu)助電源(yuan)的接線(xian)與(yu)儀(yi)表(biao)(biao)的接線(xian)圖是(shi)否一(yi)致，接線(xian)是(shi)否有(you)松(song)動或脫落現(xian) 象；2.使用萬用表(biao)(biao)測量輔(fu)助電源(yuan)輸入電壓(ya)值是(shi)否在儀(yi)表(biao)(biao)正常工作電壓(ya)值范圍內。

6.2 信號(hao)輸入故障 故障表(biao)(biao)現(xian)：儀表(biao)(biao)通電(dian)后顯(xian)示(shi)功(gong)(gong)率(lv)(lv)(lv)或電(dian)能計(ji)數不(bu)準。 故障排除：將儀表(biao)(biao)顯(xian)示(shi)界(jie)面切換至功(gong)(gong)率(lv)(lv)(lv)（有功(gong)(gong)功(gong)(gong)率(lv)(lv)(lv) P、功(gong)(gong)率(lv)(lv)(lv)因數 PF）界(jie)面，檢(jian)查功(gong)(gong)率(lv)(lv)(lv)顯(xian) 示(shi)是否為(wei)負(fu)以(yi)及功(gong)(gong)率(lv)(lv)(lv)因數是否在(zai) 0.60-0.95 之間，后再(zai)檢(jian)查電(dian)流(liu)信號(hao)線進、出線是否接反（即 電(dian)流(liu)的(de)進線一定要與儀表(biao)(biao)的(de)進線端(duan)一致(zhi)），與儀表(biao)(biao)上(shang)的(de)接線圖一致(zhi)。

6.3 通(tong)(tong)訊故(gu)障 故(gu)障表現：儀表通(tong)(tong)電(dian)后無法與上位(wei)機正常通(tong)(tong)訊。 故(gu)障排除: 1.測量儀表通(tong)(tong)訊輸出(chu) A、B 之間的電(dian)壓值應(ying)在+(4.0-5.0)V 之間； 2.檢(jian)查通(tong)(tong)訊接(jie)線方式是否按照接(jie)線圖(tu)要求正確(que)接(jie)線（即(ji)儀表的通(tong)(tong)訊接(jie)線端子 A/B 要與通(tong)(tong)訊串口 A/B 相對應(ying)）；
