Connect Control Wiring
Termination is available for the EchoConnect station communication bus (Belden 8471 or approved
equal). EchoConnect requires one pair of wires (data+ and data -). The total combined length of an
EchoConnect wire run cannot exceed 1,640 feet (500m), with a maximum distance of 1,313 feet (400m)
between any two devices.
Step 1:
Remove the two pin screw terminal connector from the termination board.
Step 2:
Connect the Belden 8471 wires to the 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.
Step 3:
Connect one 14 AWG (1.6mm) Echo station ESD ground wire (Protective Earth) to the
provided ESD ground terminals inside the unit.
Final Installation
Step 1:
Replace the front cover to the unit.
Step 2:
Supply power to the unit.
Step 3:
Check the front panel status indicators for faults.
Status Indicators
When power is applied, the Power LED located on the front panel illuminates green.
If a fault is discovered in the control wiring, the Power LED goes out and the Fault LED illuminates red.
This condition typically means that the station wiring has a fault; however it could mean a connected
device is having an issue.
N o t e :
All low voltage control cables must run in separate conduit from power wires. To
maintain the integrity of the voltage separation, a voltage barrier is provided in the unit
to separate all low voltage wiring from the AC input.
N o t e :
A qualified technician should inspect the system wire and terminations first, then
proceed to disconnecting devices, troubleshooting the fault and correcting it. The
power supply will update the fault indicators automatically when the fault condition is
cleared.
