5. User guide
5.1 TB48XXF-T110X Operation principle and Wiring hint
Input 220Vac, after rectification power module, output 48V. When the power grid normal, the battery will supply power according to system requirement, and to be charged at same time; when power off, the battery will supply energy, to make sure the DC power system working normally, to realize uninterruptible power supply. The power supply has second disconnection function, when the battery voltage is low, the battery output would be cut off to protect battery life.
5.2 Operation panel direction(TB48XX Series general reference)

5.3 sleep mode
The system would go into low-consumption mode in any of the following conditions:
- Single module or the whole system over discharge protection not recovered in 30s
- Press the keys for 3s
- The minimum single voltage lower than sleep voltage, and the lasting time reach sleep delay time( no communication, no protection, no balance, no current at same time).
- Standby more than 24h( no communication, no charge or discharge, no AC input).
- Force shutdown through upper-computer software.
Before sleep mode, please make sure there is no input voltage, otherwise it can no go to sleep mode.
5.4 wake up
- Connect to charger, and the charger output is more than 48V.
- Press the keys for 3s;
- Connect to communication cable, open upper computer software( if it goes to sleep mode due to over discharge protection, this method would not wake up the circuit board).
Remark: single model or the whole system goes to low-consumption mode after over discharge protection, it would be wake-up every 4hs, to open discharge MOS. If it can be charged, it would exit sleep mode and start normal charge; if it fails to be charged after 10times of wake-up automatically, there would be no automatic wake-up.
