If the FX’s AC source is available, the yellow AC IN
STATUS light will blink. The FX will connect to the
utility grid when the voltage is within 108-140 VAC and
the frequency between 59.3-60.5 Hz. After about 30
seconds, the AC IN light should stop blinking and stay
lit. A five-minute waiting period begins before selling
or charging can occur. The FX can then perform a
battery charge using the available AC.
• Turn the AC input breakers ON.
