The form-C alarm contact will be triggered for any condition that lights the red
FAULT LED, or shuts down the output of the inverter.
AC Transfer Switch
The automatic AC transfer switch ensures that your load is primarily powered from
the AC grid or generator when available, and is quickly transferred to the battery
powered inverter output should the AC power source fail. Transfer time is typically
less than 1 AC cycle, and the voltage transfer thresholds may be adjusted using the
back panel DIP switch settings shown in Table 4. The output will be supplied by the
inverter when the external line voltage is less than the Vac-Low setting, and will be
transferred back to the external AC source when the voltage rises above the Vac-
High setting.
