ETC Setup Guide
Rack Mount Station Power Supply with Auxiliary
Connect Power
Three IEC power cables are provided with this unit from the factory including US, UK, and Shuko. Supply
the Echo Station Power Supply with a single phase of 100-120VAC (.25A max) or 230-240 VAC
(.125A max), 50-60Hz.
Step 1:
Connect EchoConnect (Station Bus) Wiring and ESD Ground
Termination is available for up to six runs of EchoConnect station bus wiring to the removable pluggable
connector labeled "Station Bus" on the rear panel of the unit. EchoConnect is a two-wire topology-free
system that allows the E-SPM-RM-A to provide power for up to 16 Echo sensors and stations and allows for
up to 16 power controllers. EchoConnect is a bidirectional protocol that uses one pair of wires (data+ and
data-) for both data and power. ETC recommends using Belden 8471 (or approved equal) Class II wire.
Note:
ETC requires that all stations be grounded. Pull an additional 14 AWG (2.5mm
provided ESD Ground terminal bar when control wires are not installed in grounded metal conduit.

Step 4:
Connect 24 Vdc Auxiliary Power Wiring
Termination is provided for up to 5 runs of auxiliary power to the removable pluggable connector labeled
"Aux Power" on the rear panel of the unit. Auxiliary power provides 24 Vdc power that is required to
power compatible Echo devices.

Rack Mount Station Power Supply with Auxiliary
Connect the regional specific IEC power cable to the receptacle on the rear of the unit.
The total combined length of an EchoConnect wire run (using Belden 8471, or equal) may
not exceed 1,640 feet (500m).
Remove the 16 pin screw terminal connector labeled "Station Bus" from the rear panel.
Connect the Belden 8471 wires to the two pin screw terminal connector. This connection is
polarity dependent. Refer to the connector label for notation of "data+ and data-".
• Connect the white wire to the data + terminal.
• Connect the black wire to the data - terminal.
Replace the connector to the rear panel.
When required, terminate the 14 AWG (2.5mm
provided ground terminal bar on the rear of the unit.
Remove the 10 pin screw terminal connector labeled "Aux Power" from the rear panel.
Connect the auxiliary power wires, typically 16 AWG (1.5mm
terminals. This connection is polarity dependent. Refer to the connector label for notation of
"+ and -".
• Connect the red wire to the + terminal.
• Connect the black wire to the - terminal.
Replace the connector to the rear panel.
