check that Battery Type is set to Lithium battery.
Step 7 If the green indicator of one BCU blinks at super short intervals and the red
indicator is steady on, switch on the battery circuit breaker on the battery cabinet
where the indicator blinks at super short intervals. In this case, the green
indicators of all BCUs blink intermittently, and you cannot switch on the battery
circuit breakers on other battery cabinets or start the UPS in cold mode.
Step 8 Wait for about 15s. After the green indicators of other BCUs blink at super short
intervals and the red indicator is steady on, switch on the battery circuit breaker
on each battery cabinet where the green indicator on the BCU blinks at super
