Commissioning
Step 1
. Ensure all DC cables are tight 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 other source accordingly until voltage difference is in safe
ranges under 2.5V.
A hot connection with difference in voltage can cause very high
equalization current which can burn the fuses of the battery!
Measure the voltage of the battery before connecting the dc
Cables.
Step 3
. Turn BMS board ON/OFF switch to the ON position (figure 4 pos 3)
Step 4
. Connect Multi-purpose button if not connected to the BMS board connector see
(figure 4 pos 5)
Step 5
. Hold multi-purpose button until light come on.
Note: If commissioning two or more batteries.
Once the system is switched on and load is added, measure current flow on
each battery. Ensure that the load is distributed across each battery equally.
If the battery does not switch the main protection Contact ON in 7
seconds, please check BMS board indication LED for faults. See section BMS
