9 == 2.2 Connection procedure ==
10
11 The mounting area of the BMS Main 2.1 must be protected from mechanical particles (dust, dirt, large objects) and water. The installation site must provide convenient access for subsequent connection to the device’s headers.
12
13 1. Connect the charging and discharging contactors to the P6-P9 headers.
14 1. Connect a current sensor to the P12 header according to its documentation. The positive current direction (indicated by an arrow on the sensor) corresponds to the battery charging. It is recommended to use a shielded cable to connect the current sensor, the shield should be grounded on the side of the current sensor. The cable should be positioned as far as possible from the high current circuits. If the current sensor has a reference voltage line, connect it to pin 4 of the P12 header.
15 1. Connect the BMS Main 2.1 to the on-board CAN network. Observe the rules for connecting CAN devices. If the BMS Main 2.1 is the last device on a bus, close pins 1-2 on the P21 jumper, otherwise leave the jumper on pins 2-3.
16 1. Connect a power supply to the P1 header. It is not recommended to power the BMS Main 2.1 from the battery only, since at a critical discharge of the battery, it is not possible to turn on the BMS and close the charging contactor.
