ETA-20SH
AC Power Conditioning & Suppression Module
INTRODUCTION
The ETA Systems ETA-20SH is a 120V 60Hz AC Electrical Control Module (ECM), 20A Single Housing (SH) Power Conditioner and AC
Spike Suppressor that is designed to be used as a standalone unit or in conjunction with an ETA Systems Sequence controller ETA-
ECS6RM or the ETA-ECS3 up to 1000' away.
The ETA-20SH features noise filtering for removing unwanted Radio Frequency Interference (RFI) and EMI filters to reduce noise from
Electromagnetic Interference (EMI) caused by items such as electric motors or switching power supplies. The benefit of these filters
can be seen on video products or audibly by reducing static pops and external signal interference. If an AC spike or surge appears,
the ETA-20SH also incorporates Clamping Suppression technology to prevent the unwanted energy from getting into your AV system.
Other features include a Manual Bypass Switch, Incoming AC presence LED, Active LED and an AC Fault indicator. When interfaced
with the ETA-ECS6RM Sequencer controller, Extreme Voltage Shutdown (EVS) Circuitry is active, along with Voltage and Current status
readings.

INTERNAL FEATURES OF THE ETA-20SH – PROTECTION BEHIND THE PANEL
•
EMI/RFI Filters
ECM filters unwanted Radio Frequency Interference (RFI) that is commonly introduced into the AC lines by nearby radio
transmitters or wireless products. EMI filters are incorporated to reduce noise from Electromagnetic Interference (EMI) produced
by such items as electric motors or switching power supplies. The benefit of these filters can be seen on video products or
audibly by reducing static pops and external signal interference.
•
AC Spike Protection
ECM modules feature AC spike suppression. AC Spikes, or Transients, are commonly caused by utility power plant grid
switchovers. The amount of energy that can be injected into the power system can be immense with voltages reaching 6kV or
amperage peaks of 3000A. These spikes are very fast and usually only last for a very short period of time. To protect against
this potential problem, incoming AC Mains have special suppression circuitry to eliminate the unwanted energy. This circuitry is
very fast and can suppress unwanted energy within a nanosecond, while sustaining the suppression up to 2 milliseconds, thus
ensuring virtually trouble free protection.
•
•
AC Surge Protection
High line can also be known as surges. Surges usually are a slower steady state rise in voltages ranging from 128VAC and up.
They can be caused by fluctuations in the utility company's power lines or industrial equipment turning on and off, and are on the
same power leg of the building's incoming AC.
EVS Protection
If an ECM Module is connected to the ETA-ECS6RM, the ETA-ECS6RM has built in intelligence that monitors the AC lines from
the ECM modules and will inform you of potentially damaging voltages. If the AC Mains voltage is between 128VAC and 132VCA
or 107VAC and 101VAC the display will flash an error code indicating a potential fault has occurred and you should check sensitive
equipment. If an extreme voltage swing occurs above 128VAC or below 101VAC, the Extreme Voltage Shutdown (EVS) protection
circuit will automatically turn all remote ECM modules off until the system is manually reset. The EVS feature can be defeated if
required via the ETA-ECS6RM EVS bypass switch.
•
Over Current Protection
In the case of excessive current draw at the ECM module, an internal Slow Blow fuse will open and protect the devices plugged
in to the ECM module. Note: This fuse must be changed by a qualified service technician.

ETA-20SH
AC Power Conditioning & Suppression Module
ECM DATA WIRE AND DISTANCE
The ETA-20SH is one of four different types of ECM Modules requiring the same interface connectivity to the ETA-ECS6RM. All ECM
Modules can be interfaced with the ETA-ECS6RM. For connection between the ETA-ECS6RM and an ECM module, use a 5 conductor
cable that is a minimum of 22 gauge wire. We suggest using CAT5 cable due to the common availability and low cost. Heavy gauge
wire or cable with a high voltage rating are not needed because the data signal and supply voltage are low current. Pay special
attention to the port connections and DO NOT MISWIRE or damage may occur. The distance between the ETA-ECS6RM and the ECM
Module can be up to 1000ft.
USING THE ETA-20SH AS A STANDALONE UNIT
The ETA-20SH can be used as standalone unit for local equipment protection. It does not need to be connected to an ETA-ECS6RM to
operate. You still get protection against AC spikes from short power surges and you get all the EMI/RFI power conditioning filtering.
Without connecting to an ETA-ECS6RM, the ETA-20SH does not utilize the Extreme Voltage Shutdown (EVS) protection and the Voltage
and Current Status readings. To active the ETA-20SH via an external contact closure or switch plate, set the slide switch to “External
Trigger” and apply the contacts across terminals “+” and “D” shorting them together.
REMOTE ACTIVATION VIA SWITCH OR DCV TRIGGER
The ETA-20SH can be used as standalone units for local equipment protection. It does not need to be connected to a ETA-ECS6RM to
operate. You still get protection against AC spike from lightening or short power surges and you get all the EMI/RFI power conditioning
filtering. What you do not utilize is the extreme Voltage Shutdown (EVS) protection and Voltage and Current status readings. The ETA-
20SH must be connected to the ETA-ECS6RM to get the entire benefits of the ETA-20SH. To active the ETA-20SH apply DCV 5 -24VDC
to the “+” and “G” terminals.
Wiring for Remote Activation via
Switch or DCV Trigger
WIRING WITH AN ETA-ECS6RM SEQUENCER CONTROLLER
Example – ETA-ECS6RM wired to 4 ETA-ECM20 or ETA-ECM20M Modules in the Atlas Power ECM-RACEWY6 and two separate ETA-

ETA-20SH
AC Power Conditioning & Suppression Module
ETA-ECS6RM SEQUENCER CONTROLLER INTERFACE WITH ETA-20SH
To get maximum use of the ETA-20SH we suggest using the ETA-ECS6RM controller. When the two are interfaced the ETA-ECS6RM
controller not only can remotely turn on the ETA-20SH but it can monitor the AC Mains Voltage and Current of the ETA-20SH. When
mated, the microprocessor in the ETA-ECS6RM can determine if there are any potentially damaging AC Voltages present at the ETA-
20SH and shut it off before damage can occur to sensitive equipment connected.
1. ECM Control Ports – Up to 6 AC Main circuits can be activated or monitored by the ETA-ECS6RM. Each ECM control port
connects to one of the following ECM modules: ETA-ECM20M, ETA-15SH, ETA-20SH, or the ETA-ECM20. For connection
between the ETA-ECS6RM and an ECM module, use a 5 conductor cable that is a minimum of 22-gauge wire. We suggest
using CAT5 cable due to the common availability. Pay special attention to the port connections and DO NOT MISS WIRE or
damage may occur. The distance between the ETA-ECS6RM and an ECM module can be up to 1000'.

ETA-20SH
AC Power Conditioning & Suppression Module
Wiring With an ETA-ECS3 Sequencer Controller
ECM DCV Trigger - The ETA-ECS3 can handle 15A of current before the breaker opens. If 15A is not enough current to support your
power requirements you can use the 24VDC trigger to activate an additional power outlet such as the ETA-20SH. This triggered 24VDC
voltage works in conjunction with Sequence 3 timing section. Contact ETA Systems for AC outlet options.
Mounting Rails – The ETA-20SH can be mounted into most racks that have at least 12" of internal height. The housing has breakaway
rail mounting tabs that make it convenient to secure the raceway in most applications. There are two rails to secure the ETA-20SH to a
cabinet or wall. Multiple slots are provided for ease of installation. When mounting to a rack rail system use 10/32" x 1" screws, when
mounting to a wall surface use two #8 Wood or Metal Screws. To break the rail tabs off, simply bend the rail tabs back and forth with a
pliers until the metal separates.
Note: After the metal breaks, sharp corners may need to be filed to prevent injury.

TROUBLESHOOTING THE ECM MODULE AS A STANDALONE UNIT
Note: All troubleshooting should be done by a certified electrician.
Issue 1: Incoming AC LED is not illuminated.
Possible Cause #1: Incoming AC Mains circuit breaker has tripped due to excessive load.
Action Needed: Check the AC outlet that the ECM is plugged into for 120V AC voltage. If no voltage is present, check to see if
the AC outlet is on a GFI and check to see if it was tripped. If it has not been tripped trace the AC Mains outlet
back to the electrical panel and check the AC Mains breaker to see if it is tripped.
Possible Cause #2: AC Mains power is ok (120V), internal 20A (ETA-ECM20, ETA-ECM20M, ETA-20SH) Slow Blow fuse is blown.
Action Needed: Open ECM unit and replace the fuse with a Slow Blow type.
Issue 2: AC Fault LED is Flashing.
Possible Cause: 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, the clamping circuit can be
damaged during the suppression.
Action Needed: The unit will need to be repaired or replaced. It is important to have all equipment that was connected to
that ETA-20SH Module be inspected for proper operation. Note: The unit will still operate but no AC Spike or
Suppression protection will be available.
Issue 3: ECM Active LED is not illuminated.
Possible Cause: Slide switch is not set to Manual ON.
Issue 4: Unit is set to External Trigger, the incoming AC LED is illuminated but the Active LED is not illuminated.
Possible Cause #1: External Switch is not connected across the “D” and “+” terminals.
Possible Cause #2: External DCV is not connected across the “+” and “G” terminals.
Possible Cause #3: External DCV voltage polarity is not correct across the “+” and “G” terminals.
Possible Cause #4: External DCV voltage is too low to activate the trigger circuit. Must be a minimum of 5VDC.

Possible Cause The AC Mains Voltage at the ECM Module reached between 127-132VAC or the voltage dropped between
107-101VAC.
Action Needed The ETA-ECS6RM must be re-sequenced to turn off the LED, measure the AC mains before restarting the
ECM Module. If the voltage is between 117VAC and 123VAC you may proceed to reset the ETA-ECS6RM by
restarting the start up sequence.
Note: It is important to have all equipment that was connected to the module inspected for proper operation. If
the problem persists, contact your local power company for the cause of unstable AC line conditions.
