INTRODUCTION
Thank you for purchasing the ETA Systems Electrical Control Module Raceway system. This manual is divided up into two main
sections, ETA-RACEWY6 housing and the ETA-ECM20/ETA-ECM20M modules. This manual will explain which ECM module to choose
for your application, how to configure it, and how to wire it. Note: For your safety all electrical wiring must be done by a qualified
electrician. Many of the items required to connect to the raceway system are standard electrical industry components.
There are three segments for a remote 120V AC Mains sequenced system to fully operate.
1. The Electrical Control Modules (ECM) turn ON or OFF the 120V AC Mains to the devices that are plugged into it.
2. ETA-RACEWY6 housing supports and encloses the ETA-ECM20/ETA-ECM20M modules for safety.
3. An ETA-ECS6RM controller activates the ECM modules. This manual covers the ECM modules and the ETA-RACEWY6.
The ETA-RACEWY6 is the housing that supports up to six ETA-ECM20 or ETA-ECM20M modules. There are four ½" and ¾" dual
knockouts that support standard electrical conduit components for wiring 120V AC mains into the raceway housing from the electrical
panel. If six sequenced sections are not needed there are two ECM-3BP blank plates included to cover the unused ECM module slots.
Other blank plates are available as an accessory item.
The ETA-RACEWY6 can be mounted into most racks that have at least 60" internal height. The raceways have breakaway mounting
tabs that make it convenient to secure the raceways in most applications.
The ETA-ECM20/ETA-ECM20M is an Electrical Control Module (ECM) 20A Power Conditioner and AC Spike Suppressor module that is
designed to be placed next to an ETA-ECS6RM Controller or up to 1000 ft away.
Features of the ECM modules vary allowing the customer to choose what is best for their installation. All ECM modules feature AC
spike suppression. AC Spikes, or Transients, are commonly caused by lightning storms or 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 for up to 2 milliseconds, thus ensuring virtually trouble free
protection. High and low AC Main line voltages are another major contributor to equipment failures. The ECM modules support EVS
circuitry which enables the module to be shut off during low and high AC Line conditions.
The ETA-ECM20M also features noise filtering for removing 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) generated by items such as electric motors, switching power supplies and lightning. The benefit of these filters can
be seen on video products or audibly by reducing static pops and external signal interference.
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 from fluctuations from the utility company's power lines, or industrial equipment turning on and off, and is on the same
power leg of the building's incoming AC.
Low line is also known as brownouts. This happens when the AC Mains drops below 107VAC. Most of the time it is caused by the
utility company not being able to supply enough power during heavy utility consumption time periods, such as heat waves. Another
factor would be from voltage drops in AC lines due to long transmissions. The ETA-ECS6RM will inform you if any of these conditions
occur. Extreme variances in Unstable AC Mains voltage are one of the main reasons for equipment failure.
The ETA-ECM20 does not support the same current monitoring or EMI / RFI Filter feature as the ETA-ECM20M, ETA-20SH and the
ETA-15SH models. However, it does support AC Spike and Surge Suppression, AC Mains Voltage monitoring, EVS circuitry and Remote
Activation. Refer to selected ECM Module for full details.

APPLICATIONS
The Electrical Control Module Raceway system was designed to be flexible with features that allow it to be used in a variety of
applications. The sequenced outputs allow the turning of equipment On and Off in a particular order, to eliminate an in-rush of current
and audible pops that often occur with non-sequenced power strips. It also can be used solely for protection against lightning strikes or
voltage surges. If fuzzy video or frequent static pops occur, the AC power conditioning will eliminate or reduce those inconveniences.
The following are just a few examples of applications in which the Atlas Power Electrical Control Module Raceway system can be
used:

ETA-RACEWY6 ECM HOUSING
The ETA-ECM20 and ETA-ECM20M require an electrical housing. The ETA-RACEWY6 holds up to 6 ECM modules. There are standard
¾" and 1" electrical knockouts on the bottom of the raceway to support standard electrical mounting hardware. Since the Raceway can
house 6 ECM modules there can be 6 separate 20A AC legs coming into the Raceway for a total of 120A of power distribution or it
could be as simple as one 20A leg. Note: All electrical wiring must be done by a certified electrician.
All cover plates must be secured tightly. There shall be no open slots. Blank cover plates are available. Top and bottom mounting tabs
are incorporated to mount inside an ETA Systems Rack. All rack mount rails are designed to be breakaway, if they are not needed.
Simply bend the tab back and forth until the tab breaks away. Be careful of sharp edges.
RACEWAY AC INLET KNOCKOUTS
The ECM-6RACEWAY6 can support up to four AC conduit inlets. There are three knock outs on the bottom and one on the top of the
raceway. Each inlet supports a double knock out size supporting standard USA electrical fittings of 1/2" and ¾". The figure below is an
illustration of the bottom of the raceway.

RACEWAY AC GROUND STUD
The ETA-RACEWY6 has an internal AC Mains chassis grounding stud for EARTH connection. The stud size is 10⁄32" x 1". A nut and star
washer are also supplied. The figure above shows the internal location of the stud.
RACEWAY MOUNTING RAILS
The ETA-RACEWY6 can be mounted into most racks that have at least 60” of internal height. The raceways have breakaway rail
mounting tabs that make it convenient to secure the raceway in most applications. There are four rails to secure the ETA-RACEWY6 to
a cabinet or to a wall. Multiple slots are provided for ease of installation. 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.

ECM (ELECTRICAL CONTROL MODULES) MODULES
The difference between the ETA-ECM20 & ETA-ECM20M Models
The ETA-ECM20 does not support the same current monitoring or EMI/RFI Filter feature as the ETA-ECM20M, ETA-20SH and the
ETA-15SH models. However, it does support AC Spike and Surge Suppression, AC Mains Voltage monitoring, EVS circuitry, and
Remote Activation.
In certain application we suggest using an ETA-ECM20 module vs. an ETA-ECM20M, like in places where some of the features would
be redundant because of the electrical location of the ECM module. This would be a cost savings to use a less expensive ECM module
where redundant circuitry is not needed.
Example: One 20A incoming AC line where two sequenced AC outlets are required. Use one ETA-ECM20M and one ETA-ECM20
module wired in parallel. Explanation: If the AC Mains system required a sequenced outlet and did not require more than 20A of
service for a portion of the AC power system, an ETA-ECM20M module can be placed in parallel with an ETA-ECM20 module. It is not
necessary to have amperage readings from both ECM Modules because you can read the current from the ETA-ECM20M module.
It could be in parallel with a ETA-ECM20 module instead since it's on the same incoming AC line as the ETA-ECM20M. They would
have the same current reading because they are in parallel. Also, the EMI and RF filtering are across the same AC line leg, so both
ECM Modules connected to that line are filtered, no need for redundant filtering. Note: In this wiring configuration you still get the
Voltage monitoring to see if the module is active and have extra surge protection. See ECM Module wiring configurations.

ETA-ECM20 & ETA-ECM20M MODULE PANEL FEATURES
1. Trigger / Status Port Pin Identification – all signals are of low voltage and current. DO NOT MISWIRE or damage may occur.
A. (+) requires a minimum of 5 -24V DC to activate the module with 5mA of current. Note: The DCV can be supplied from any
source. The EVS protection requires the ETA-ECS6RM for operation.
B. G = Circuit Ground, Must be of the same circuit as the DCV source.
C. V = AC Voltage Status Signal, this signal reports back to the ETA-ECS6RM the Incoming AC Mains Voltage to the ECM
module.
D. A = AC Current Status Signal, this signal reports back to the ETA-ECS6RM the AC Mains Current draw at the ECM module.
Note: Not available on ETA-ECM20 type module.
E. D = Fault Status Signal, reports to the ETA-ECS6RM fault conditions of a ECM module.
2. External Trigger / Manual On Switch – The ETA-20SH and ETA-ECM20 have a manual override switch allowing them to be used
as a local Power Conditioner and Surge Suppressor. For it to be remotely monitored and activated the switch must be in the
“External Trigger” position.
3. Incoming AC LED – This LED will illuminate Red when the ECM has incoming AC power present at the module. This LED must
be ON to operate. Note: If this LED is not illuminated check the following: 1) The unit is plugged in, 2) The AC Mains Breaker
feeding the AC leg to the ECM module is OFF, 3) The internal fuse has been damaged. This should only be inspected by an
authorized technician.
4. Active LED – This LED will illuminate Green when the ECM module has sensed the proper DCV to trigger activate the power ON
circuit. Note: If connected to the ETA-ECS6RM and the EVS circuit is activated this LED will not be on. The Channel Status LED on
the ETA-ECS6RM will flash indicating a problem and will not turn the ECM module ON until the AC Mains voltage is stable.
5. AC Fault LED – If damage to the Spike Suppression circuit occurred this LED will illuminate RED. This LED will not turn OFF until
repaired. Have the ECM module inspected by a qualified technician. Note: Not available on ETA-ECM20 type module.
6. AC Mains Outlet – Two 120V AC 15A outlets.

INTERNAL ECM FEATURES OF THE ECM MODULES
Protection behind the Panel
 • EMI/RFI Filters – ECM noise filtering for eliminating 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) from such items as electric motors, switching power supplies and lightning. The benefit of
these filters can be seen on video products or audibly by reducing static pops and external signal interference.
Note: Not available on ETA-20RW type module.
 • AC Spike Protection - ECM modules feature AC spike suppression. AC Spikes, or Transients, are commonly caused by lightning

from 128VAC and up. They can be caused from fluctuations from 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. Note: Not available on ETA-20RW type module.
 • Over Current Protection – In the case of excessive current draw at the ECM module. An internal Slow Blow fuse will open
protecting the devices plugged in to the ECM module. Note: This fuse must be changed by a qualified service technician.

ECM-3BP MODULE BLANK COVER PLATE
The ETA-RACEWY6 can hold up to 6 ETA-ECM20 Modules; however it is ok to use less than 6 modules. The open slots on the
ETA-RACEWY6 can be covered up using an ECM Module Blank Plate cover. Two of these are included with the ETA-RACEWY6. If not
needed, discard them. If additional Blank Plates are required they can be purchased in packages of three.
ECM-ACIN WIRE KIT
ETA Systems offers a wire kit of stranded 12 guage UL wire for wiring the ETA-ECM20 Modules together plus additional length for
wiring the incoming AC to an AC Mains panel. 140" of each color of Green, White and Black are included. Note: As a reference, it takes
around a foot of wire between ETA-ECM20 modules. If they are wired on the same incoming AC Main, it is highly recommended that
you carefully measure the wire needed for the job. It may take more than one ECM-ACIN wire kit depending on how many AC Mains
are being used and the distance from the AC Mains Panel. It is not necessary to use the ETA Systems ECM-ACIN wire kit as long as it
is 12 guage and UL listed.
WIRING THE ETA-M20RW CONTROL MODULE
The ETA-ECM20 & ETA-ECM20M are designed to be mated with the ETA-RACEWY6 housing and the ETA-ECS6RM controller. The
specific job install AC power requirements and power distribution layout will dictate how the ETA-ECM20M Modules are wired into the
Raceway. Each ECM Module can be wired as a single 20A run or in a parallel configuration as illustrated below. Each ECM module has
dual 3-position screw terminal blocks that are in parallel and are clearly labeled as follows: E - Green = Ground, L - Black = Load,
N - White = Neutral.
NOTE: The above figures show the ECM wiring configuration of one 20A AC Main line coming into an ETA-ECM20M, then paralleling
with an ETA-ECM20 type module.
NOTE: It appears that the wiring is in series but the ECM-Module In/Out terminals are in parallel on the PCB.

ECM MODULES CONNECTION TO AN ETA-ECS6RM CONTROLLER
ETA-ECS6 CONTROL PORTS FOR ECM MODULES
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 and 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 MISWIRE or damage may occur. The distance between the ETA-ECS6RM and
an ECM module can be up to 1000ft.

Each Channel of the ETA-ECS6RM also has a Relay contact that works in conjunction with the ECM control port. Sequencing and
timing of these connections are the same as the corresponding ECM channels. Example: Sequence 1 ECM Port output works at the
same times CH 1 Relay contact. Note: All ECM modules can be trigger using the Relay contacts to activate the ECM module. Se ECM
module for details.
ETA-ECS6 WIRING CONFIGURATION
Example 1 – ETA-ECS6RM wired to six ETA-ECM20 or ETA-ECM20M Modules.
Example 2 – ETA-ECS6RM wired to 4 ETA-ECM20 or ETA-ECM20M Modules in the ETA-RACEWY6 and two separate ETA-15SH and
ETA-20SH housings.

ECM DATA WIRE AND DISTANCE
There are six ECM control ports on the ETA-ECS6RM and up to 6 ECM Modules can be connected to the ETA-ECS6RM. The four
different types of ECM Modules require the same interface connectivity to the ETA-ECS6RM. All ECM Modules and be interchanged
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. 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.
ECM MODULE ACTIVATION WITHOUT USING ETA-ECS6 OR AN ETA-ECS3 CONTROLLER
Any of the ETA-ECM20, ETA-ECM20M, ETA-15SH or the ETA-20SH Modules can be triggered to activate without using an ECS type
Controller. Any DCV supply will activate the ECM buy applying DCV 5-24VDC to the “+” and “GND” terminals. An external switch will
also activate an ECM by applying a contact to short terminals “+” and “D” together.
Note: The EVS and Voltage monitoring will be disabled using either of these methods.
The ECM 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 ECM does not utilize the Extreme Voltage Shutdown (EVS) protection and the Voltage and
Current Status readings To active the ECM 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.

ECM TROUBLESHOOTING
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, 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 it is tripped.
Possible Cause #2: AC Mains power is ok (120V), internal 15A (ETA-15SH) and 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 illuminated
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
AC Mains Line to be inspected for proper operation.
Issue 3: ECM Active LED is not illuminated.
Possible Cause: Slide switch is not set to Manual ON.
Issue 4: Unit is set 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 to low to activate the trigger circuit. Must be a minimum of 5vDC.
