Connection
Installation
The mounting location must be protected from mechanical obstacles (dust, dirt, large objects) and water. Device placement should provide easy access for connection.
| Parameter | Value |
| Overall dimensions (length × width × height), mm | 140 × 60 × 14 |
| Mounting dimensions (length × width), mm | 130 × 50 |
| Mounting holes | M3 |
Headers
The BMS IMD has two headers for connecting the power line (X3 and X4), a header for connecting external equipment and power supply (X2), a chassis connection header (X1) and a jumper which connects a terminal resistor to the CAN bus (J1).
