11. AC Fault Indicator–AlthoughtheDualClampingSuppression(DCS)circuitvirtuallyassuresprotectionfrommosttransient
voltage spikes and surges nature has a way of occasionally creating electrical forces that are beyond the capabilities of any device
to absorb without some degree of damage. In the rare instance that this occurs and the DCS circuit has been damaged, the Red

unit is repaired. Note: If the AC Fault LED is illuminating it is important to have all equipment that was connected to that AC
Mains Line inspected for proper operation.
12. AC Mains Abnormal Voltage Indicator–ThisLEDflashesunderseveralACMainsfaultsituationsthatarelistedbelow.Normal
operating voltages for AC Mains voltage is considered to be between 108VAC and 125VAC. Any voltages exceeding those
parameters are considered a risk to damage equipment plugged into the ETA-ECS3.
High AC Line Mains–TheAbnormalVoltageLEDwillflashbetween128VAC–132VACindicatingpossibledamagemayoccur
to equipment due to high AC Mains voltage. The ETA-ECS3 outlets will remain active but the LED will stay flashing even if the
