Introduction
Thank you for purchasing the Atlas Power Electrical Control Module Raceway system. This manual is divided up into two main
sections, the ECM-RACEWY housing and the ECM-20, ECM-20M, and ECM-30 modules. This manual will explain which ECM module
to choose for your application, how to configure it, and how to wire it. Note: For your safety all electrical wiring must be done by a
qualified electrician. Many of the items required to connect to the raceway system are standard electrical industry components.
There are three segments for a remote 120V AC Mains sequenced system to fully operate.
1. The Electrical Control Modules (ECM) turn ON or OFF the 120V AC Mains to the devices that are plugged into it.
2. ECM-RACEWY housing supports and encloses the ECM-20, ECM-20M, and ECM-30 modules for safety.
3. An ECS-6RM controller activates the ECM modules. See the ECS-6RM manual for more information. This manual covers the
ECM modules and the ECM-RACEWY.
The ECM-RACEWY housings support up to six ECM-20, ECM-20M, or ECM-30 modules. There are four ½” and ¾” dual knockouts that
support standard electrical conduit components for wiring 120V AC mains into the raceway housing from the electrical panel. ECM-3BP
blank plates can be purchased to cover unused ECM module slots. Two blank plates are provided with the ECM-RACEWY6.
The ECM-RACEWY6 holds up to six ECM modules and can be mounted into most racks that have at least a 60" internal height. The
ECM-RACEWY3 holds up to three ECM modules and requires an internal height of 31" while the ECM-RACEWY1 for a single ECM
module requires a 14" internal height. The raceways have breakaway mounting tabs to conveniently secure the raceways in most
applications.
The Atlas Power ECM-20 and ECM-20M are 20A Power Conditioner and AC Spike Suppressor Electrical Control Modules (ECM) that
are designed to be placed up to 1000 ft away from an ECS-6RM Controller. The ECM-30 is a 30A Power Conditioner and AC Spike
Suppressor Electrical Control Modules (ECM).
All ECM modules feature AC spike suppression. AC Spikes, or Transients, are commonly caused by lightning storms or utility power
plant grid switchovers. The amount of energy that can be injected into the power system can be immense with voltages reaching 6kV
or amperage peaks of 3000A. These spikes are very fast and usually only last for a very short period of time. To protect against this
potential problem, incoming AC Mains have special suppression circuitry to eliminate the unwanted energy. This circuitry is very fast
and can suppress unwanted energy within a nanosecond, while sustaining the suppression for up to 2 milliseconds, thus ensuring
virtually trouble free protection. High and low AC Main line voltages are another major contributor to equipment failures. The ECM
modules support Extreme Voltage Shutdown (EVS) circuitry so the module can be shut off during low and high AC Line conditions.
High line, or surges, usually are a slower steady state rise in voltages from 128VAC and up. They can be caused by fluctuations from
the utility company’s power lines or industrial equipment that is on the same power leg of the building’s incoming AC turning on/off.
Low line, or brownouts, occur when the AC Mains drops below 107VAC. This is caused by the utility company not being able to supply
enough power during heavy utility consumption times like heat waves or from voltage drops in AC lines due to long transmissions. The
ECS-6RM will inform you if any of these conditions occur. Extreme variances in Unstable AC Mains voltage are one of the main reasons
for equipment failure.
The ECM-20M features noise filtering for removing unwanted Radio Frequency Interference (RFI) that is commonly introduced into the
AC lines by nearby radio transmitters or wireless products. EMI filters are also incorporated to reduce Electromagnetic Interference
(EMI) generated by items such as electric motors, switching power supplies, and lightning. The benefit of these filters can be seen on
video products or audibly by reducing static pops and external signal interference.
The ECM-20 and ECM-30 do not support the same current monitoring or EMI/RFI Filter feature as the ECM-20M, ECM-20SH, and
ECM-15SH models. However, they do support AC Spike and Surge Suppression, AC Mains Voltage monitoring, EVS circuitry and
Remote Activation. Refer to appropriate ECM Module for full details.
