|---|---|---|---|
| 1 | B+ B- | Power port connected to battery side total positive and total negative | Plug-in terminal (GPS50AFP) |
| 2 | P+ P- | Power port connected to charging equipment (UPS) or DC bus | Plug-in terminal (GPS50AFP) |
| 3 | AC 220V | The municipal power supply signal input port must be taken from the UPS output side | When there is mains power, the BMS is turned on; when there is no mains power, the BMS is turned off (ensure that the BMS and the mains are turned on and off synchronously to save the self-consumption of the battery by the BMS) |
| 4 | ON OFF | On: the circuit breaker is on; Off: the circuit breaker is disconnected | When the handle of the circuit breaker is in the tripping state in the middle position, it needs to be turned to Off before it can be closed. |
| 5 | D1 D1 D2 D2 | Two dry contact output reserved | Prohibit charging, Prohibit charging Dry contact output |
| 6 | Start | DC start button: start RBMS system by taking power from the battery side. | The system is connected to the battery. After the circuit breaker is closed, press and wait for the light to light up, indicating that the system is powered on. |
| 7 | System | System status indicator | System normal: the green light is always on System alarm: the yellow light is always on Self test failure and protection status: the red light is always on Charging: the green light flashes Discharge: red light flashing Self checking: red and green flashing alternately Pre-charging: yellow flashing |
| 8 | 1 2 4 8 | ID allocation: when multiple RBMs are used in parallel, the ID is allocated by setting the dial switch. You must start with 1 | The dial switch has 4 bits in total and supports up to 15 RBMs Parallel machine 1 ON: ID+1 2 ON: ID+2 3 ON: ID+4 4 ON: ID+8 |
| 9 | LAN | RBMS host computer system software can be connected to PC through network cable | The network cable standard is CAT5 or above, and can be connected by cross line or straight line. The line sequence can be according to the standard tia-586A or tia-568B |
| 10 | T-CAN T-485 | Terminal matching resistance setting during can and 485 communication Setting Description: (120R), on is valid | For parallel application, only the last one needs to be set; Single machine should be used flexibly according to the site conditions (interference, communication distance, etc.) |
| 11 | COM1 COM2 | RBMs external communication port: In parallel application: communicate with SBMS In stand-alone application: communicate with UPS / PCS external equipment | The shielded twisted-pair cable harness must be used randomly. The cable sequence is defined in the cable harness label |
| 12 | GND 24V | For supplying power to SBMS | |
| 13 | BMU-OUT | Communication interface with BMU | communication with BMU level |
| 14 | RBMS cabinet ground point | Must be grounded, and the grounding resistance is less than 1Ω |
