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, to avoid high equalization currents.
A bad connection with voltage drops 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 2 pos 3).
Step 4
. Connect Multipurpose button if not connected to the BMS board connector see
(figure 2 pos 5).
Step 5
. Hold Multipurpose button until light comes 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 contactor ON in 7
seconds, please check BMS board indication LED for faults. See section BMS
Error and Warnings on page 13 of this manual.
