MODULE PANEL FEATURES

1.Trigger / Status Port Pin Identification – All signals are of low voltage and current. DO NOT MISWIRE or damage may occur.

+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.

VAC Voltage Status Signal, this signal reports back to the ETA-ECS6RM the Incoming AC Mains Voltage to the ECM module.

AAC 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.

DFault 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.

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.

6.AC Mains Outlet – Two 120V AC 20A outlets.

WIRING THE ETA-ECM20M MODULE

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:

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.
