4.4 Connecting device
For UL applications, the following must be observed:
– Maximum ambient temperature: 55 °C
– Use 60/70°C copper lines only
Make the connection as follows:
1. Remove terminal covers of the device
2. BMS bus connection:
Connect the terminals ABMS and BBMS (4) to the BMS bus (A to A, B to B). If the COM465… is at
the end of the BMS bus, you must switch the terminating switch on the device (7) to "ON".
3. Modbus RTU connection:
Connect the terminals AMB and BMB (3) to the Modbus RTU (A to A, B to B). If the COM465… is
at the end of the bus, you must switch the terminating switch on the device (6) to "ON".
4. Establish connection with PC and BCOM:
Connect Ethernet cable (RJ45) to the COM465… (5) and connect to the PC network. It is recom-
mended to use at least on Ethernet cable of category 5 (Cat. 5).
