battery is discharged, and the UPS system has completely shut down.
This message indicates the Rotary Switch is still in Position 4 when input
power is restored.
[Turn the Rotary Switch to Position 1 and perform a UPS start-up
procedure.]
Rotary switch improperly operated The Rotary Switch has been operated improperly. This means the switch
has been operated either too fast or in the wrong direction.
[Turn the Rotary Switch to Position 1 and perform a UPS start-up
procedure.]
