	5
61.1	6	To perform the protection functions, the BMS must be able to disconnect the battery from the load and charger. To do this, at least one contactor able to break the load and charge circuits must be connected to the BMS.
57.1	7
59.1	8	Before use, configure the system. Proper operation of the BMS is possible only if it is correctly configured.

	11	(((
57.1	12	The BMS can be connected to batteries with life-threatening and health-hazardous voltage levels. When working with high-voltage batteries, observe electrical safety regulations, use safety glasses, protective clothing, insulated tools and appliances. To prevent the damage of device avoid electrostatic discharges while working with the battery.

27.1	342
41.1	343	The BMS Main 3 / BMS Main 3X device implements a circuit for hardware opening of power contactors when the discrete input signal DIN7 and/or DIN8 (voltage level 9-32V) is removed. To enable this function, jumper J5 and/or J6 must be installed.

27.1	386
	387	All operations to connect the device must be carried out with the supply voltage removed.
	388
	389	* Connect the power contactors to header X2.
	390	* Connect one or more current sensors, as well as external temperature sensors (if necessary) to header X5.
	391	* Connect BMS Logic devices to header X9.
	392	* Connect digital inputs and outputs (if necessary) to header X3.
	393	* Connect the high voltage bus (if necessary) to headers X11-X14.
	394	* Connect the high-voltage network integrity circuit (if necessary) to header X4.
	395	* Connect external devices (if necessary) to header X6.
	396	* Connect other devices (BMS Indication, BMS Display, if necessary) to header X7.
40.1	397	* If the BMS Main 3 / BMS Main 3X is the last device on the RS-485-1, CAN1, or CAN2 bus, install jumpers J1-J3.
27.1	398	* 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.
