ECM-3BP Module Blank Cover Plate
It is not necessary to have a module installed in every slot of the ECM-RACEWY6 or the ECM-RACEWY3, however, there should be no
open slots to prevent the risk of damage or serious injury. ECM Module Black Plates can be used to cover open slots. Two blank plates
are included with the ECM-RACEWY6 only. Additional Blank Plates can be purchased in packages of three. Note: The ECM-RACEWY1
and ECM-RACEWY3 do not include a cover plate.
ECM-ACIN Wire Kit
Atlas Sound offers a wire kit of stranded 12 gauge UL wire for wiring the ECM-20 Modules together plus additional length for
wiring the incoming AC to an AC Mains panel. 140" (3.5m) of Green, White, and Black wire are included. As a reference, it takes

that you carefully measure the wire needed for the job. It may take more than one ECM-ACIN wire kit depending on how many AC
Mains are being used and the distance from the AC Mains Panel. It is not necessary to use the Atlas Sound ECM-ACIN wire kit as long
as the wire used is 12 gauge and UL listed.
Wiring the ECM Control Modules
The ECM Control Modules are designed to be paired with the ECM-RACEWY housings and the ECS-6RM controller. The specific job
install AC power requirements and power distribution layout will dictate how the ECM Modules are wired into the Raceway. Each ECM
Module can be wired as a single 20A or 30A 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 ECM-20M, then paralleling with
an ECM-20 type module. This can also be done with the ECM-30, however you cannot combine an ECM-20 and ECM-30 on the same
circuit. Note: It appears that the wiring is in series but the ECM Module In/Out terminals are in parallel on the PCB.
Note: The ECM-20 and ECM-20M require 12 gauge wire. The ECM-30 requires 10 gauge wire.
