ETA-20SH
AC Power Conditioning & Suppression Module
ECM DATA WIRE AND DISTANCE
The ETA-20SH is one of four different types of ECM Modules requiring the same interface connectivity to the ETA-ECS6RM. All ECM
Modules can be interfaced with the ETA-ECS6RM. For connection between the ETA-ECS6RM and an ECM module, use a 5 conductor
cable that is a minimum of 22 gauge wire. We suggest using CAT5 cable due to the common availability and low cost. Heavy gauge
wire or cable with a high voltage rating are not needed because the data signal and supply voltage are low current. Pay special
attention to the port connections and DO NOT MISWIRE or damage may occur. The distance between the ETA-ECS6RM and the ECM
Module can be up to 1000ft.
USING THE ETA-20SH AS A STANDALONE UNIT
The ETA-20SH can be used as standalone unit for local equipment protection. It does not need to be connected to an ETA-ECS6RM to
operate. You still get protection against AC spikes from short power surges and you get all the EMI/RFI power conditioning filtering.
Without connecting to an ETA-ECS6RM, the ETA-20SH does not utilize the Extreme Voltage Shutdown (EVS) protection and the Voltage
and Current Status readings. To active the ETA-20SH via an external contact closure or switch plate, set the slide switch to “External
Trigger” and apply the contacts across terminals “+” and “D” shorting them together.
REMOTE ACTIVATION VIA SWITCH OR DCV TRIGGER
The ETA-20SH can be used as standalone units for local equipment protection. It does not need to be connected to a ETA-ECS6RM to
operate. You still get protection against AC spike from lightening or short power surges and you get all the EMI/RFI power conditioning
filtering. What you do not utilize is the extreme Voltage Shutdown (EVS) protection and Voltage and Current status readings. The
ETA-20SH must be connected to the ETA-ECS6RM to get the entire benefits of the ETA-20SH. To active the ETA-20SH apply
DCV 5 -24VDC to the “+” and “G” terminals.
WIRING WITH AN ETA-ECS6RM SEQUENCER CONTROLLER
Example – ETA-ECS6RM wired to 4 ETA-ECM20 or ETA-ECM20M Modules in the Atlas Power ECM-RACEWY6 and two separate
ETA-15SH and ETA-20SH modules.
