NOTE: In the maintenance bypass mode, the load will be powered from the input AC source,
independent of its voltage level.
* If inverter failure or DC input loss occurs, and AC input voltage is greater than 112% of nominal, the system will shut down
to protect users equipment.
** If overload is not removed, unit will transfer to Bypass, Inverter Ready will be displayed (see specification).
