3.1.5 Battery

电池

         The battery is an optional accessory and therefore not part of delivery of the CPU module. The battery serves for saving the SRAM contents (e.g. process and configuration data) in the event of power failure and to supply the real time clock. The CPU module monitors the battery status (capacity). A low battery capacity warning is displayed before data storage is at risk (about 2 weeks in advance). Upon this warning message, the battery should be replaced as soon as possible. For more detailed information, please refer to Section 4,Accessories.

      电池是可选件，不作为CPU的一部分（随机销售）。电池用于在发生电源故障时保存 SRAM 内容（如过程和配置数据），并提供实时时钟。CPU模块会监视电池容量的状态，在数据存储面临风险前2周会显示低电量警告信息。一旦出现此（低电量）警告信息，请尽快更换电池。更多信息请参阅附件第 4 节。
