output relay changes to LOW. Backup operation is stopped when the battery voltage
falls below 18.5 V (typical). If the battery is left with backup operation stopped, the
standby current of the S8T-DCBU-01 may cause the battery to continue discharging,
considerably reduce the service life of the battery, and render recharging and backup
impossible. To prevent this, refer to Battery Overdischarge on page 4.
