Siemens SIPROTEC 5 Hardware Description

Battery
Description
The battery lies in an externally accessible battery compartment. The battery compartment is located on the
rear of the base module. You need not open the device when replacing the battery.
If the auxiliary voltage fails, the battery ensures continued operation of the internal clock and storage of
certain data (statistic values, values of thermal models) for at least 6 months. The parameterization, logs, and
fault records are stored in a non-volatile memory and are fail-safe at all times.
The device cyclically checks the charge of the battery. The Battery fault indication is issued if the actual
voltage falls below the minimum.
