5. AC Protect Active LED
Although the Clamping Suppression circuit virtually assures protection from most transient 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circuithasbeendamaged,theGreen“ACProtectActive”LEDindicatorwillturn
Off, indicating that the AC Protect Circuitry is no longer protecting equipment connected to the Switched outlets. The unit will still
operate as an AC distribution unit but the surge suppressor protection will not function until the unit is repaired. Note:Beadvisedthat
activation of this fault condition and the associated repair is not covered under warranty. If the AC Protect is disengaged, it is important
to have all equipment that was connected to that AC Mains Line be inspected for proper operation.
