Configuration
975-0170-01-01 3–25
Lo AC Freq
Full name Low AC transfer frequency (AC under frequency level)
Configurable setting This setting lets you adjust the lowest frequency at which the
inverter/charger no longer qualifies AC as “good” and attempts to transfer
to invert mode.
You can adjust Lo AC Freq settings as follows:
When to use This setting can be used when the AC supply frequency is lower than the
set value required for the electrical equipment.
Outcome The lower frequency of the AC supply above which it will be qualified as
“good” by the inverter/charger can be varied.
Hi AC Volt
Full name High AC transfer voltage (AC over voltage level)
Configurable setting This setting lets you adjust the voltage above which the inverter/charger
no longer qualifies AC as “good” and transfers to Invert.
You can adjust Hi AC Volt settings as follows:
When to use This setting lets you adjust the AC parameters when AC supply is outside
the upper voltage range required for electrical equipment.
Outcome The upper limit of the voltage that will be qualified as “good” by the
inverter/charger can be varied.
