12.2 Battery for MP2100/MP2100M
One battery can be connected to the MP2100/MP2100M. This battery is used to back up data to prevent the data

Fully insert the connector attached to the end of the battery leads for the ZZK000064 Battery specified by
YASKAWA into the MP2100/MP2100M connector.

year. The warranty period of the battery is five years from the date of purchase. These values, however, differ
according to the operating conditions, including the ambient temperature.
If the BAT indicator on the MP2100/MP2100M lights, replace the battery with a replacement battery
