Installation Requirement: One SB821 unit required per CPU or I/O module requiring backup power.
Industrial Applications
- Process Control: Maintains PID loop parameters and alarm setpoints in chemical, pharmaceutical, and food processing plants during power interruptions
- Oil & Gas: Preserves critical safety system configurations in offshore platforms and pipeline control stations
- Power Generation: Ensures turbine control logic and protection settings remain intact during grid disturbances

Installation Guide
- Mounting: Snap SB821 unit onto 35mm DIN rail in control cabinet, typically adjacent to CPU module
- Connection: Plug TK821V020 cable connector into battery port on CPU or I/O module (refer to module manual for exact location)
- Verification: Power up system and check CPU diagnostics for battery status (should indicate "Battery OK")
- Documentation: Record installation date on battery unit label for maintenance tracking
Safety Note: Do not attempt to recharge SB821 lithium battery. For rechargeable backup, use SB822 model instead.
Maintenance & Replacement
Battery Life Monitoring: ABB S800 I/O and AC 800M systems provide automatic battery voltage monitoring with low-battery alarms typically 3-6 months before depletion.
Replacement Indicators:
- CPU displays "Battery Low" or "Battery Fault" alarm
- Battery voltage drops below 3.0V (check via system diagnostics)
- Battery has been in service for 8-10 years (preventive replacement)
Replacement Procedure:
- Order replacement SB821 unit (Part Number: 3BSE018109R1)
- With system powered, disconnect old battery cable from CPU
- Connect new SB821 battery cable immediately (within 30 seconds to prevent data loss)
- Remove old battery unit from DIN rail and dispose per local regulations for lithium batteries
- Clear battery fault alarm in system diagnostics
