Battery Installation and Replacement

The Battery in the MP3300 backs up the data that is saved by the MP3300 when power to the
CPU Module is lost due to power failure or when the power to the MP3300 is turned OFF. The
Battery provides backup power for the following data.
• M registers
• S registers
• Trace memory
• Alarm history
• Table data
• Calendar
• The CPU Module comes with one Battery. The Battery is not connected when the Module is
delivered.
• The Battery can provide backup power for the memory for a total power OFF time of 1 year.
Important
However, this depends on the actual operating conditions, such as the ambient temperature.
• When the total power OFF times reaches 1 year, the voltage of the Battery will drop, and the
BAT indicator on the CPU Module will light. When this occurs, always replace the Battery with a
new one within two weeks.
Delayed replacement of the Battery will result in loss of the data stored in the memory of the
CPU Module.
• The Battery is warranted for 5 years.
