MODULE PANEL FEATURES  
WIRING THE ETA-ECM20M MODULE  
1. Trigger / Status Port Pin Identification All signals are of  
low voltage and current. DO NOT MISWIRE or damage may  
occur.  
The ETA-ECM20M is 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 ETA-RACEWY6. 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:  
+ Requires 5 -24VDC 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.  
G Circuit Ground, Must be of the same circuit as the DCV  
source.  
V AC Voltage Status Signal, this signal reports back to the  
ETA-ECS6RM the Incoming AC Mains Voltage to the ECM  
module.  
E - Green = Ground  
L - Black = Load  
N - White = Neutral  
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.  
D Fault Status Signal, reports to the ETA-ECS6RM fault  
conditions of an ECM module.  
2. External Trigger / Manual On Switch The ETA-ECM20M  
has a manual override switch allowing it 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 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.  
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.  
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.  
5. AC Fault LED If damage to the Spike Suppression circuit  
occurred this LED will illuminate Red. The module may still  
operate but may not be protecting the items plugged into  
the AC outlets. 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.  
Note: It appears that the wiring is in series but the ECM Module  
In/Out terminals are in parallel on the PCB.  
6. AC Mains Outlet Two 120V AC 20A outlets.
