1.产 品 详 情 资 料：
外部电池规格：•类型：3.6 V、16 Ah的低速率锂电池•尺寸：ANSI尺寸D/IEC R20•锂含量：5.6 g电池必须在以下情况下更换：•PM8xx B（电池）LED闪烁或熄灭。•多次或长时间停电。•由于维护或故障，系统停机时间延长。更换SB821外部电池单元中的电池更换外部电池：1。断开SB821装置电缆连接器。2.将SB821装置从DIN导轨上松开。3.小心地拆下SB821单元盖并识别外部电池。4.阅读并遵守外部电池上的警告标签/文字。5.小心地拆下电池。6.插入可维修的蓄电池，检查蓄电池极性和方向是否正确。有关电池的详细信息，请参阅第392页的SB821外部电池–AC 800M内存备份。由于电池是并联的，因此在使用SB821外部电池时，有必要从处理器单元中取出内部电池，以避免减少可用的内存备份时间。
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.
