225 225  == Connection procedure ==
226 226  
227 227  All operations to connect the device must be carried out with the supply voltage removed.
228 228  
229 -* Connect the power contactors to headers X4-X7.
230 -* Connect one or more current sensors to headers X8 and X9.
231 -* Connect external temperature sensors (if necessary) to header X10.
232 -* Connect BMS Logic devices to header X11.
233 -* Connect digital inputs and outputs (if necessary) to header X1.
234 -* Connect external devices (if necessary) to header X13.
235 -* Connect other devices (BMS Indication, BMS Display, if necessary) to header X12.
236 -* If the BMS Main 2R is the last device on the CAN2,  RS-485-1 or CAN1 bus, install jumpers J1-J3.
237 -* Connect an external power supply to header X3. The device will start when there is a 9-32V power supply.
374 +* Connect the power contactors to header X2.
375 +* Connect one or more current sensors, as well as external temperature sensors (if necessary) to header X5.
376 +* Connect BMS Logic devices to header X9.
377 +* Connect digital inputs and outputs (if necessary) to header X3.
378 +* Connect the high voltage bus (if necessary) to headers X11-X14.
379 +* Connect the high-voltage network integrity circuit (if necessary) to header X4.
380 +* Connect external devices (if necessary) to header X6.
