Question about Powerware 9120 UPS System
Powerware 9120 shows "Battery Failure" almost immediatelly after power on. It is not a battery issue. Sometimes also blows the 6.3 A fuse. IF anyone has successfully faced such an error please advice.
Sounds like inverter is unhappy(causing the input fuse to blow. maybe, just maybe, this Powerware 9120 has given up the ghost? The inverter can short for a variety of reasons. Try to take out the battery completely, and run it as just a power conditioner. If that works, then you have an unhappy inverter in there.
