TOSHIBA 1600XPi Series UPS Installation and Operation

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)

Output: Voltage regulation ± 3%, THD<3% (linear load)/<6% (nonlinear load), overload capacity 125%/30 seconds, 150%/10 seconds, bypass overload 125%/10 minutes, 1000%/1 cycle

Efficiency: AC-DC-AC efficiency ≥ 83% (3.6-10KVA),>86% (14-22KVA)
