BMS12/200
ENGLISH
1. Mount the BMS preferably on a vertical surface, for optimal
cooling.
2. Determine the rating of fuse AB (see figure and table 1).
The fuse on input AB doubles as a shunt. The BMS will limit the
input current according to the rating of this fuse. For fuse ratings
and corresponding current limit please see table 1.
Choosing the right fuse will prevent overheating of the alternator
and/or DC cabling.
3. Determine the rating of fuse LB (see figure).
This fuse should be rated in accordance with the expected load
current and the cross section of the cabling to the load.
4. Disconnect the cabling from the plus pole of the starter battery.
5. Pull off the REMOTE on/off connector to prevent unwanted
switching of the BMS.
6. Install and connect all electrical cabling and fuses AB, LB, but
leave the plus poles of the Li-ion batteries and starter battery
disconnected.
7. Daisy-chain the battery control cables between the Li-ion batteries
and connect to the BMS.
8. Connect the plus cabling to the Li-ion batteries and the starter
battery.
9. Reinsert the REMOTE on/off connector on the BMS.
The BMS is now ready for use.
Notes:
a) A battery charger can be connected to input AB instead of the
alternator.
b) The Li-ion batteries can be charged as well as discharged through
input/output LB.
c) When a load with a large electrolytic capacitor bank (such as an
inverter or inverter/charger rated at 1200VA or more) is connected
to LB, the BMS will limit its average output current during start-up
to approximately 80A. Therefore the capacity to simultaneously
start-up other DC loads is limited to 80A. Once the capacitor bank
is fully charged, the current limit increases to 400A.
