Before installing we strongly suggest you read the entire manual to ensure you benefit from all the features of the ETA-ECS3. The  
ETA-ECS3 can be placed on a shelf or rack mounted in a standard 19" width rack. Placement within a rack is not critical but the rack 
should be within 6' of dedicated 15A AC outlet. Always make sure the 15A outlet is properly inspected by a certified electrician prior to
connecting the ETA-ECS3. Below are a few installation tips.

•  After plugging the ETA-ECS3 into a 15A AC Mains outlet inspect the Wiring Fault LED for illumination. The LED should not be on.

•  Inspect the equipment that is to be plugged into the ETA-ECS3 to ensure it does not exceed 15A total amperage draw.

•  Divide the equipment into three categories. Pick the outlets that match the outlets equipment use.

Issue:     

Wiring Fault LED is illuminated. 

Possible Cause: 

  AC Mains outlet is wired incorrectly.

Action Needed: 

  Contact a certified electrician to inspect the building's wiring.

Issue:    

No power to the AC outlets.

Possible Cause: 

  Circuit breaker has tripped due to excessive load.

Action Needed: 

  Remove one piece of equipment from the ETA-ECS3, and push the breaker re-set tab located on the front panel.  
Note: We suggest first locating the highest power-consumer such as a power amplifier and disconnecting or turn-
ing down that unit. If the ETA-ECS3 breaker continues to trip, relocating some of the gear may be required.

Issue:    

No power to the AC outlets, “Abnormal Voltage” indicator is illuminated, the Volt Meter is Flashing and you hear a

 

buzzer from the unit.

Possible Cause: 

  The AC Mains Voltage exceeded 132VAC or the voltage dropped below 101VAC.

Action Needed: 

  Measure the AC mains before the ETA-ECS3. If the voltage is between 117VAC and 123VAC you may proceed to 
reset the ETA-ECS3 by restarting the start up sequence.  
Note: It is important to have all equipment that was connected to that AC Mains Line inspected for proper opera-
tion. If the problem persists, contact your local power company for the cause of unstable AC line conditions.

Issue:     

Abnormal LED Flashing when you have power to all outlets.

Possible Cause: 

  The AC Mains Voltage exceeded 128VAC or the voltage dropped below 107VAC

Action Needed: 

  The ETA-ECS3 must be re-sequenced to turn off the LED. Measure the AC mains before the ETA-ECS3. If the volt-
age is between 117VAC and 123VAC you may proceed to reset the ETA-ECS3 by restarting the start up sequence.  
Note: It is important to have all equipment that was connected to that AC Mains Line inspected for proper opera-
tion. If the problem persists, contact your local power company for the cause of unstable AC line conditions.

Issue:     

AC Fault LED is Flashing, a buzzer is sounding and you have no power at any outlets.

Possible Cause: 

  Although the Dual Clamping Suppression (DCS) 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, the DCS circuit has been 
damaged during the suppression. 

Action Needed: 

  If this happens, the ETA-ECS3 will shut off and the unit will need to be repaired or replaced. It is important to have 
all equipment that was connected to that AC Mains Line inspected for proper operation.
