EXAMPLES ETA-ECM20/M20RW MODULE WIRING CONFIGURATIONS

The ETA-ECM20/M20RW is designed to be mated with the ECM-RACEWY6 housing and the ETA-ECS6RM controller. The specific job 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:

ECM Module PCB Labeling For incoming AC Mains:

Note: The above figure shows 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.

Example 1

ECM wiring configuration showing one 20A AC main line coming into an ETA-ECM20M then paralleling with 5 ETA-ECM20 type modules.

Note: It appears that the wiring is in series but the ECM Module In/Out terminals are in parallel on the PCB.

Example 2

ECM wiring configuration showing two 20A AC main lines coming into the raceway for a total of 40A available. The 20A legs are separated by feeding a 20A leg to two different ETA-ECM20M Modules. The leg is then paralleled with two ETA-ECM20 type modules. Note: It appears that the wiring is in series but the ECM Module In/Out terminals are in parallel on the PCB.
