Preparing batteries
Before you can connect the BACS modules, the batteries must be prepared. In addition to the general safety guidelines for work on live
components and live cables, please note the following when handling the BACS power cables: Each BACS measuring cables provides
an own fuse, integrated in the positive pole of the cable.
As soon as faulty currents leave the tolerance range, these fuses trip in order to interrupt the contact between the BACS module and the
associated battery. By doing so, the BACS module will be protected from damage.
Please note, this fuse is not designedt be removed or repaired. The entire cable need to be changed during maintenance work at the
according battery:
Short circuits inside large battery systems are very dangerous depending on battery type, it can lead to explosive gases, escaping high
corrosive acids as well as acid gas. It may also lead into fire feeded by chemistry.
Never try to replace or repair the fuse!
During initial installation, please obeye following:
Once load is connected to the BACS cable, current will inevitably flow when as soon as contact with the battery poles is established.
During installation work, an unnoticed repeated brief touching of the battery poles can may trigger fuse while connecting to the battery.
In some cases, the fuse will continue working for the moment but is permanently damaged and will trigger short time later. For this
reason, there is an installation row to be followed:
First connect the cables to the battery poles and then connect the BACS modules to the pre-coded connector. This will prevent such an
internal damage at the fuse.
Since battery connectors may vary depending on model and manufacturer, the basic connection procedure is always the same
procedure:
Connect the BACS measuring cables to the poles of the battery. Ensure not reversing the polarity of the cable, the fuse in the
measuring cable will be triggered immediately and the cable need to be exchanged:
Red cable: Positive pole of the battery
Black cable: Negative pole of the battery
