1.產(chǎn) 品 詳 情 資 料：
外部電池規格：?類(lèi)型：3.6 V、16 Ah的低速率鋰電池?尺寸：ANSI尺寸D/IEC R20?鋰含量：5.6 g電池必須在以下情況下更換：?PM8xx B（電池）LED閃爍或熄滅。?多次或長(cháng)時(shí)間停電。?由于維護或故障，系統停機時(shí)間延長(cháng)。更換SB821外部電池單元中的電池更換外部電池：1。斷開(kāi)SB821裝置電纜連接器。2.將SB821裝置從DIN導軌上松開(kāi)。3.小心地拆下SB821單元蓋并識別外部電池。4.閱讀并遵守外部電池上的警告標簽/文字。5.小心地拆下電池。6.插入可維修的蓄電池，檢查蓄電池極性和方向是否正確。有關(guān)電池的詳細信息，請參閱第392頁(yè)的SB821外部電池–AC 800M內存備份。由于電池是并聯(lián)的，因此在使用SB821外部電池時(shí)，有必要從處理器單元中取出內部電池，以避免減少可用的內存備份時(shí)間。
Specifications for the external battery: ? Type: Low-rate lithium battery, 3.6 V, 16 Ah ? Size: ANSI Size D / IEC R20 ? Lithium contents: 5.6 g The battery must be exchanged whenever: ? The PM8xx B(attery) LED flashes or is extinguished. ? Multiple or extended power cuts have occurred. ? Extended periods of system downtime have occurred for maintenance or malfunctions. Replacing the Battery in an SB821 External Battery Unit To replace an external battery: 1. Disconnect the SB821 unit cable connector. 2. Release the SB821 unit from the DIN-rail. 3. Carefully remove the SB821 unit cover and identify the external battery. 4. Read and comply with the Warning label/text on the external battery. 5. Carefully remove the battery. 6. Insert a serviceable battery and check that battery polarity and orientation are correct. For further battery details see SB821 External Battery – AC 800M Memory Back-up on page 392. Due to the batteries being connected in parallel, it is necessary, when using the SB821 external battery, to remove the internal battery from the processor unit in order to avoid reducing available memory back-up time.
