HPFB and connect an FG wire between each HPFB FG screw.
10. To test the HPFB, remove the DK14 AC plug from the AC outlet. The DK14 AC LED will go
out, but the DK14 DC LED remains on. Also the system remains in normal working order and
the HPFB 24V LED remains on.

to press the Battery Off switch.
CAUTION!
Once the HPFB is turned Off or unplugged (during AC power loss) it will not
operate again until AC power is restored to the DK14 KSU.
