Installation and connection
Safety rules
Before use, configure the system. Proper operation of the device is possible only if it is correctly configured.
Installation
Overall and mounting dimensions of BMS Indication are shown on figure below:
| Parameter | Value |
| Overall dimensions (length × width × height), mm | 61 × 49 × 27 |
| Mounting dimensions (length × width), mm | 55 × 43 |
| Mounting holes | M3 |
Headers
The BMS Indication has two headers for connecting the BMS (P2 and P3), a header for connecting external equipment (a PC, for example), and a switch which connects a terminal resistor to the CAN bus (SWD1).
P2, P3 – headers for communication with BMS
Receptacle Housing: Molex 39012040. Terminals: Molex 5556
| Pin | Name | Description |
| 1 | CANH | CAN H line for communication with the BMS controller |
| 2 | CANL | CAN L line for communication with the BMS controller |
| 3 | +5V | Supply voltage 5 V |
| 4 | GND | Ground |
J1 – header for external equipment
| Pin | Name | Description |
| 1 | - | - |
| 2 | CANL | CAN L line for communication with external equipment |
| 3 | - | - |
| 4 | - | - |
| 5 | - | - |
| 6 | GND | Ground |
| 7 | CANH | CAN H line for communication with external equipment |
| 8 | - | - |
| 9 | - | - |
SWD1 – CAN terminal resistor switch
To connect the terminal resistor between the CANH and CANL lines, switch the SWD1 to the ON position.
