10. Overload Alarm <FUNC9>：Set the overload alarm. When the SD-series
output power is higher than the set value, the SD-series will sound a “beep”
to remind you that the unit is going to shut-down. At the same time, the
internal Dry Contact Relay will open/close.
Default = 104% Setting range = 50%~110%
11. Shut-down retry <FUNC10>：When SD-series is shut-down under OVP, UVP,
Overload or short circuit conditions, the inverter will automatically try to
restart according to below：
Protection type

13. Saving Interval <FUNC12>：When SD-series inverter enters power saving
mode, it will detect AC Load periodically.
Default = 2.0 Seconds Setting range = 1.0S ~ 2.0S
If the AC Load is 3 times higher than Saving Level, inverter will recover and
output normally to AC Load.
