Raceway ECM Housing
The ECM-20, ECM-20M, and ECM-30 require an electrical housing. The ECM-RACEWY6 holds up to 6 ECM modules, while the
ECM-RACEWY3 holds up to 3 ECM modules, and the ECM-RACEWY1 holds 1 ECM module. There are standard
1
⁄2" and
3
⁄4" dual
knockouts on the bottom of the raceway to support standard electrical mounting hardware. Since the Raceways can house multiple
ECM modules there can be separate 20A or 30A AC legs coming into the Raceway for a total of 120A of power distribution or it could
be as simple as one 20A or 30A leg. Note: All electrical wiring must be done by a certified electrician.
For safety, there should be no open slots and all cover plates must be secured tightly. Blank cover plates are available if all slots will not
be used. Top and bottom mounting tabs are incorporated to mount inside an Atlas Sound Rack. Rack mounting tabs are designed to be
bent over or breakaway, if not needed. Simply bend the tab back and forth until the tab breaks away. Be careful of sharp edges.
Raceway AC Inlet Knockouts
The ECM-RACEWY can support up to four AC conduit inlets. There are three knock outs on the bottom and one on the top of the
raceway. Each inlet supports a double knock out size supporting standard USA electrical fittings of
1
⁄2" and ¾". The figure below is an
illustration of the bottom of the raceway.
