Switching the Battery ON
Step 1
. Make sure all DC cables are tightened according specifications.
Step 2

difference between battery voltage and DC bus is not more than 2.5V. If greater than 2.5V
please Charge or Discharge the 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 5
. Hold multi purpose button until the light comes on.
If the battery does not switch the main protection Contact ON in 7
