產(chǎn)品安規(guī)設(shè)計之要求與測試（ppt54頁)(文件)
【正文】 或直接連上 WAN、或直接透過電話線路傳送資料 or連結(jié) ,皆屬 於 Tele產(chǎn)品 , 在安規(guī)定義中統(tǒng)稱為 TNV product 。 EX: DG104S. Building Networks for People ? TNV3 Circuits Tele 產(chǎn)品之相關(guān)規(guī)定 whose normal operating voltages exceed the limits for an SELV CIRCUIT under normal operating conditions on which overvoltages from Telemunication Networks are possible (AWG 26 can cover this test) TNV3 的線路是針對產(chǎn)品有直接連接至 outdoor tele 線路 , 且 其接受的電壓高於 SELV ( or 60Vdc),此類型產(chǎn)品必須做 overvoltage test, 但若有附 26號線 , 即可免做此項測試 。 凡是 TNV circuit 上的零 件、零件位置、 layout、線路一旦經(jīng)過承認後皆不可任意變更 . Tele 產(chǎn)品之相關(guān)規(guī)定 Building Networks for People ? TNV (Telemunication Network Voltage) Circuit A circuit in the equipment to which the accessible area of contact is limited and that is so designed and protected that, under normal operating and single fault conditions, the voltage do not exceed specified limiting values. ? SELV (Safe Extra Low Voltage) Circuit A SECONDARY CIRCUIT which is so designed and protected that under normal and single fault conditions, its voltages do not exceed a safe value ( or 60Vdc). Tele 產(chǎn)品之相關(guān)規(guī)定 相關(guān)名詞說明 Building Networks for People Tele 產(chǎn)品之相關(guān)規(guī)定 TNV Circuit 分為三種類型 ? TNV1 Circuits whose normal operating voltages do not exceed the limits for an SELV CIRCUIT under normal operating conditions, on which overvoltages from Telemunication Networks are possible (AWG 26 can cover this test) 總括來說 TNV1為直接連接至 outdoor的線路 , 但其接受的電 壓低於 SELV ( or 60Vdc), 此類型產(chǎn)品必須做 overvoltage test, 但若有附 26號線 , 即可免做此項測試 。角的投影範(fàn)圍內(nèi)無危險電壓零件 2. Accessibility Test : Building Networks for People C. 底部之開孔 因目前廠內(nèi)許多產(chǎn)品皆是共用 case, 在 safety standard 中 , 針對不同種類產(chǎn)品的要求不一 , 為避免產(chǎn)品 A和 B共用 case, 卻產(chǎn)生 A 可過 safety, 但 B 無法通過 safety 的狀況發(fā)生 , 所以 底部一律要求不能有任何的開孔 . 另一種需注意可懸掛式的產(chǎn)品 , 必須考慮其懸掛時 , 當(dāng)原本的側(cè)邊有可能會變成了底部時 , 則側(cè)邊一樣不能有開孔 . 2. Accessibility Test : Building Networks for People 外殼開孔 , 固然千變?nèi)f化 , 但是以 test ping 測試時不可碰觸到具危險電壓的裸露零件為原則 . 2. Accessibility Test : Building Networks for People Test Finger Test Pin Building Networks for People 2. Accessibility Test : Building Networks for People 2. Accessibility Test : Failed Passed Building Networks for People 3. Energy Hazard Measurement 適用情形 : 外部所有的 connectors, 其裸露之帶電體部分 ( 接地者除外 ) 及因任何開孔可觸及之零件 判定 : 240VA Building Networks for People 4.
