Page 10: Electrical Installation
Electrical installation Step 1. Before connecting anything be sure that the battery ON/OFF switch is at OFF position. (figure 4) Figure 4 BMS board component locations... - Page 11 Connecting Inverters/chargers/UPS to the battery unit while it is ON can cause big sparks due to capacitors inside the connected device. This can be harmful to people. Connecting the main battery terminal must be with the correct size cable based on the rated current of the battery and the charger/inverter incase it’s lower. Figure 5 connection terminals Step 2.
- Page 12 Switching the Battery ON Step 1. Make sure all DC cables are tightened according to specifications. Step 2. If the battery operates in parallel with other energy sources, make sure that the difference between battery voltage and DC bus is not more than 2.5V. If greater than 2.5V please charge or discharge the other source accordingly until the voltage difference is in a safe range under 2.5V.

Page 21: Canbus Connection
CANBUS connection. Bms EX used CAN 2.0B @ 500000 kb. Connecting other device operating at different speed rate is not allowed. For connection please use twisted pair wires in a shielded cable to minimize RF emissions. RJ45 connections can be used for daisy chaining BMS EX together using a straight Ethernet cable. The output of the Bms EX CAN transceiver is galvanically isolated. -
