8.1.3 Replacing the Basic Unit Battery

The Basic Unit has one replaceable built-in battery. This battery is used to back up data to prevent the data stored in the
memory from being lost when power is interrupted (e.g., when the power supply to the Basic Unit is turned OFF).
The built-in battery can retain the contents of the memory until the total time of power interruptions reaches one 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 Basic Unit lights, replace the battery with a replacement battery (JZSP-BA01) within two
weeks. Any delay in battery replacement will result in the data stored in the memory of the Basic Unit being lost.
The appearance of the battery is illustrated below.
Note: This battery is not commercially available. Contact your Yaskawa representative.
