No. | Name | Description | Precautions |
1 | B+ B- | Connect to the battery's total positive and total negative | Quick plug connection |
2 | P+ P- | Connect to the charging equipment (PCS) or DC bus | Quick plug connection |
3 | AC Input | The municipal power supply input port must be taken from the
UPS/Inverter output side | 85~264VAC 1A max |
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 trip state in the
middle position, it needs to be turned OFF before it can be closed
again. |
5 | D1 D1 D2 D2 | Two dry contact output reserved | The default D1 is charging prohibited, D2 is discharging prohibited |
6 | Start | DC start button: start the RBMS system By taking power from the
battery side. | The system is connected to the battery, and after the circuit
breaker is closed, press and wait until the light is on to indicate
that the system is on |
7 | System | System status indicator | System normal: Green Alarm: yellow light Self test failure and protection status: red light
Charging: 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 are allocated by
setting the DIP switch. Must start at 1 | There are 4 DIP switches in total, supporting up to 15 RBMS in
parallel
1 ON: ID+1
2 ON: ID+2
3 ON: ID+4
4 ON: ID+8 |
9 | TCP/IP | The RBMS host computer system software can be connected to the PC
through the network cable | Network cable standard CAT5 or above, crossover cable or straight
cable can be
used, 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 | In parallel application, only the last one needs to be set. In
stand-alone application, it can be used flexibly according to site
conditions (interference, communication distance, etc.). |
11 | COM-IN
COM-OUT | RBMS external communication port: When multiple RBMS in parallel:
Communication with SBMS
When RBMS Stand-alone: communicate with UPS/PCS external devices | The shielded twisted-pair cable harness
must be used randomly. The cable
sequence is defined in the cable harness
label |
12 | GND
HMI-B
HMI-A
24V | 1.For external display connection
2.For powering SBMS | Please connect the display screen according to the silk screen
sequence |
13 | BMU-OUT | Communication interface with BMU | Cascaded communication between BMU |
14 | ㊤ | RBMS chassis ground | Must be grounded, and the grounding
resistance is less than 1Ω |
