ETA-ECM30
30A AC Power Module Spike Suppressor
INTRODUCTION
Thank you for purchasing the ETA Systems ETA-ECM30 AC Power Module Spike Suppressor Unit. Note: For your safety, all electrical
wiring should be done by a qualified electrician.
The ETA Systems ETA-ECM30 is an Electrical Control Module (ECM) 30A AC Spike Suppressor that is designed to be used as a
stand-alone unit or in conjunction with an ETA-ECS6RM Controller up to 1000ft away. 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 current 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. The
ETA-ECM30 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 Extreme Voltage
Shutdown (EVS) circuitry when used with an ETA-ECS6RM controller, which enables the module to be shut Off during high and low AC
line conditions. High line voltages or 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 by industrial equipment turning On and Off when it is on the same
power leg of the building’s incoming AC. Low line voltages or brownouts occur 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 can 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.

1. Trigger/Status Port Pin Identification
All signals are of low voltage and current. DO NOT MISS WIRE 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. Reports the Incoming AC Mains Voltage to the ECM module back to the ETA-ECS6RM.
D. NC = No Connection
E. D = Fault Status Signal. Reports any fault conditions of an ECM module to the ETA-ECS6RM.
2. External Trigger/Manual On Switch
The ETA-ECM30 has a manual override switch allowing it to be used as a local Spike Suppressor. For remote monitoring and activation,
the switch must be in the “External Trigger” position.
3. Active LED
This LED will illuminate Green when the ECM module has sensed the proper DCV to activate the unit. Note: If the ETA-ECM30 is
connected to the ETA-ECS6RM and the EVS circuit has been activated, this LED will not be lit. The Channel Status LED on the
ETA-ECS6RM will flash indicating a problem and the ECM module will not turn On until the AC Mains voltage is stable.
4. AC Fault LED
If damage to the Spike Suppression circuit occurs, this LED will illuminate Red. The module may still operate but may not be protecting
the items plugged into the AC outlets. The ECM module should be inspected and repaired by a qualified technician.
5. 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 illuminating 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.

ECM HOUSING TYPES
ECM-RACEWY1
ECM-RACEWY3
ECM-RACEWY1
ECM-RACEWY3
ECM-RACEWY6
The ETA-ECM30 requires an electrical housing. These housings are manufactured by Atlas Sound and are available through ETA
Systems. The ECM-RACEWY1 holds 1 ECM module, the ECM-RACEWY3 holds up to three ECM modules, and the ECM-RACEWY6
holds up to six ECM modules. Three standard ¾" and 1" electrical knockouts on the bottom of each raceway and a distribution area
with cover plate supports standard electrical mounting hardware. Note: All electrical wiring should be done by a certified electrician.
ECM-3BP Module Cover Plate
The ECM-RACEWY3 can hold up to three ETA-ECM20/30 Modules and the ECM-RACEWY6 can hold up to six ETA-ECM20/30
Modules. If using fewer modules than the housing will hold, the open slots can be covered using an ECM Module Blank Plate. Two of
these are included with the ECM-RACEWY6. If additional Blank Plates are required, they can be purchased in packages of three.
All cover plates must be secured tightly. For safety, there should be no open slots when the raceway is in use. Top and bottom
mounting tabs are incorporated to mount inside an Atlas Rack. All rack mount rails are designed to be removed if they are not needed;
simply bend the tab back and forth until the tab breaks. Be careful of sharp edges.
ECM Data Wire and Distance
There are six ECM control ports on the ETA-ECS6RM and up to six ECM Modules can be connected to it. There are many types of ECM
Modules that require 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. It is recommended to use CAT5 cable due to the common availability and low cost. Pay special attention to the port connections
and DO NOT MISS WIRE or damage may occur. The distance between the ETA-ECS6RM and the ECM Module can be up to 1000ft.

ECM MODULE ACTIVATION WITHOUT USING AN ETA-ECS6RM CONTROLLER
Any of the ECM Modules can be triggered remotely to activate without using an ECS type Controller. If you do not need the features of
the ECS controllers, remote activation can be accomplished by applying DC external voltage or by hard switch contacts. Note: The EVS
and Voltage monitoring will be disabled when not using an ECS controller.
Remote DC Voltage Trigger
(+) requires a minimum of 5–24VDC to activate the module with
5mA of current. The DVC can be supplied from any source.
Note: The EVS and Voltage monitoring will be disabled
G=Circuit Ground. Must be of the same circuit as the DCV source.
Remote Hard Switch Contact Trigger
An external hard switch will also activate an ECM module by applying
a contact to short terminals “+” and “D” together.
Note: The EVS and Voltage monitoring will be disabled.

WIRING THE ETA-ECM30 CONTROL MODULE
The ETA-ECM30 is designed to be inserted in the ECM-RACEWY1, ECM-RACEWY3, or ECM-RACEWY6 housing. The specific job
(install) AC power requirements and power distribution layout will dictate how the ECM modules are wired into the housing. The
ETA-ECM30 Module can be wired as a single 30A run or in a parallel (loop thru) configuration. Each ECM module has dual 3-position
screw terminal blocks that are in parallel and are clearly labeled as follow: E - Green = Ground, L - Black = Load, N - White = Neutral. Use
a minimum of 10 gauge wire for a 30A rating. Follow all local electrical codes. All installation must be done by a certified electrician.
