Inverter Enabled/Disabled
Enabled: the inverter can function depending on the setting of the Inverter On/Off field. Disabled: the FXM will not
go into Inverter mode when it loses AC power.
Inverter On/Off
Selecting inverter On/Off will not turn on the inverter unless inverter is enabled first.
Inverter Off Delay Time
Used to set a delay before the inverter switches off to allow time for switching off critical loads. The set Inverter
ON/OFF delay is only available when the Alpha FXM is in the Battery or Standby modes.
The delay can be adjusted in 1 second steps with a default setting of 0 seconds to a maximum of 600 seconds
(10 minutes). The delay is only available in the Standby or Inverter modes. Once the Alpha FXM returns to the
Line mode, the delay resets to 0 seconds.
