I have an APC 1500-Pro UPS with a new battery.
During testing, I turn off the 120V circuit breaker to the UPS, and the battery beeps accordingly.
This does not turn off the 120V test lamp connected to the UPS Battery Backup outlets, but it does shutdown the computer.
I have since learned that turning off the power also breaks the APC UPS ground: I get an open ground reading through my outlet tester when it's plugged into the UPS Battery Backup outlets.
In fact, I am unable to power on the computer through the UPS Battery Backup outlets unless I turn the breaker back on and the ground closes.
Is there a way to solve this problem?
