4.4 The Battery
The SITRANS LUT400 is supplied with one battery installed. The battery (BR2032) has a life
expectancy of ten years, and is affected by ambient temperature. If the LUT400 loses input
power, the battery will maintain operation of the device’s real time clock until power has been
restored.
When the battery reaches its end of life, refer to Replacing the Battery (Page 264).
CAUTION
Disconnect power before replacing the battery.
