370 370  == Connection procedure ==
371 371  
372 372  All operations to connect the device must be carried out with the supply voltage removed.
373 373  
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.
381 -* Connect other devices (BMS Indication, BMS Display, if necessary) to header X7.
382 -* If the BMS Main 2R is the last device on the RS-485-1, CAN1, or CAN2 bus, install jumpers J1-J3.
383 -* Connect an external power supply to header X1. The device will start when there is a 9-32V power supply and one of the KEYRUN or CHARGE_ON signals with a voltage of more than 8.5V is supplied.
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.
