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.
