4.4. Connection wires
Use appropriate wire for the connection wires to prevent overheating and unnecessary
losses. Use appropriate fuses matching the wires and load. Super B suggests to use a
95mm2 connection wires. Connection wires with smaller diameters can cause overheating or
unnecessary losses.
4.5. Installing the mandatory external disconnect device
!
Warning!
Always connect the relay between the + or - terminal of the battery and the load.
!
Warning!
Never use the Li-ion battery without a properly installed external disconnect device (relay
or bistable relay).
Protecting the Li-ion battery is possible by one of the following ways:
1. Connect a bistable relay to the Li-ion battery’s Con1 output.
2. Connect a normal relay to the Li-ion battery’s Con2 (I/O connection 7) output.
3. By using the SB BIB (Battery Interface Box).
4. By using the SB BCI-C1 (Battery Communication Interface) and a normal relay.
4.5.1. Connecting a bistable relay to the Li-ion battery
1. When using a bistable relay connect it to Con1 output as displayed in figure 5.
The Con1 output controls both the ON coil and the OFF coil of the bistable relay. The output of
Con1 can be found in table 8.
