Set date (format: Day mm/dd/yyyy, such as Mon 10/05/2009)
Set time (in 12 hour format, such as 12:15 PM)
Charging: After initial startup, the battery needs to be charged for at least 24 hours (with the input circuit breaker open), otherwise the backup time will be shortened
Normal start and stop
Start: Open the rear main circuit breaker (MCCB) of the UPS and confirm that the "On Line" green light on the front panel is on; If it's not on, press the RUN button for 3 seconds (hear a beep sound)
Stop: Press the STOP button for 3 seconds (after a beep, the "On Line" light goes out and enters bypass mode); To completely stop, turn off the MCCB circuit breaker (all sensitive loads must be turned off first)
Core operating mode
Static Bypass mode: Automatically switches when UPS overload or internal failure occurs, with power directly supplied to the load through the bypass from the input, with a switching time of less than 1/4 cycle (no load interruption); After overload relief, it can automatically switch back (AutoXfer parameter needs to be enabled)
On Line mode: Normal operation mode, the input AC is converted to DC through a rectifier (including a boost chopper circuit), and the charging battery is simultaneously supplied to the inverter to generate high-quality sine wave AC output. The battery is always in a charging state
Battery Backup Mode: When the mains power is interrupted, the battery immediately supplies DC to the inverter and converts it to AC output; Backup time is 5-8 minutes (full load, depending on model), and the power supply will automatically stop when the battery voltage drops to the "shutdown voltage (Vmin)"
EPO mode (Emergency Power Off): remotely close the EPO switch (normally open), immediately cut off the UPS input circuit breaker, output, and battery circuit; After activation, wait for 5 minutes for discharge before maintenance

Battery management and maintenance
Key parameters of battery
Nominal voltage (Vnom): 3.6KVA is 144Vdc, 5.2-6KVA is 216Vdc, 8-22KVA is 288Vdc
Low voltage alarm (Vlow): 3.6KVA is 130Vdc, 5.2-6KVA is 192Vdc, 8-22KVA is 246Vdc
Shutdown voltage (Vmin): 3.6KVA is 114Vdc, 5.2-6KVA is 170Vdc, 8-22KVA is 227Vdc
Charging parameters: Charging is divided into three stages (constant current 1A → constant voltage → float charging), and it takes 24 hours to fully charge (12 hours for 90% charging)
Battery testing and storage
Test:
Automatic testing: Enable at startup, wait for the 'Battery Test Frequency (CMD 655)' time before re enabling after completion
Manual testing: In UPS online mode, log in with ADMIN privileges, set CMD 652=Disable, CMD 653=Enable, and CMD 655=0, and press the "BattTest" button on CMD 609; Test failed with 'BTSTFL' warning displayed
Storage:
Before storage: Start up and run without load for 24 hours to fully charge the battery, stop UPS and turn off MCCB
Storage conditions: Original packaging, wooden/metal tray, temperature -20-40 ℃, avoid humidity/dust/vibration
Maintenance: Charge every 9 months for temperatures below 20 ℃, every 6 months for temperatures between 20-30 ℃, and every 3 months for temperatures between 30-40 ℃
Preventive maintenance and component replacement
Daily maintenance: Keep the ventilation openings clean and regularly remove dust (using a vacuum cleaner for dusty environments)
Component replacement cycle:
Aluminum electrolytic capacitor: every 7 years
Fuse: Every 7 years
Cooling fan: Every 3.5 years for environments between 30-40 ℃, and every 5 years for environments below 30 ℃ (non hot swappable, needs to be replaced after disconnecting and discharging)
Battery: Depending on the ambient temperature, 20-25 ℃ is 5 years, 30 ℃ is 3.5 years, 35 ℃ is 2.5 years, 40 ℃ is 1.8 years, and 45 ℃ is 1.25 years (requiring overall replacement, using the same model of battery pack)
Fault Handling and Technical Appendix
Fault and warning codes
Fault code (partially critical):
BYPOH: Bypass overheating, check the fan/ambient temperature (>40 ℃ needs to be cooled down), if the issue is not resolved within 1 hour, the bypass will stop
CHRGOV: Charger overvoltage, UPS failure, record operating conditions and contact Toshiba service
DCOV: DC bus overvoltage, check input wiring/load (such as motor load), restart ineffective, contact service
Warning code (partially critical):
AOH: If the environment is overheated (internal temperature>50 ℃), check the air conditioning/fan. If it is overheated, turn off the device
BLFE: End of battery life (5-year cycle), contact Toshiba for replacement
LB: Low battery (<90% capacity), immediately turn off the load in an orderly manner and press the STOP button
Technical specifications (core parameters)
Input: Voltage 208/240V ± 10% to -30%, frequency 45-65Hz (automatic detection), power factor 0.98 (typical), THD<5% (linear load)
