Step 6: Insert each black (typical) wire from the pairs into a “B” terminal on the connector and
tighten the screw(s) firmly to secure the wire into the terminal.
Step 7: Replace the connector to the rear panel.
Step 8: A 14 AWG ground wire, if wiring is not installed in grounded metal conduit, terminates to
the ground bus located inside the enclosure.
Terminate Auxiliary Power
Auxiliary power is required when you are installing powered Unison control stations. ETC recommends
using two 16 AWG stranded wires for 24 Vdc auxiliary power to the control station(s). Auxiliary power is
topology-free. Maximum auxiliary voltage runs are dependant by the wire gauge and the distribution of
auxiliary load determined by installation. The auxiliary supply is capable of providing 36W (1.5A at
24Vdc).
The auxiliary power connector (labeled Aux Power)
provides termination for up to 20 wires in the ten position
pluggable connector. Each terminal allows up to two 16
AWG wire and provides 24 Vdc power to Unison control
stations.
Step 1: Pull auxiliary control power wiring (typically 16 AWG red / black wire pair) into the
equipment rack.
Step 2: Strip 3/16” (4.8mm) of insulation from the ends of each wire pair.
Step 3: Remove the auxiliary power connector from the I/O board.
Step 4: Loosen the terminal screws for the auxiliary wire pairs you are terminating.
Step 5: Insert the black (typical) auxiliary power wire from the pair into a “-” terminal on the
connector and tighten the screw(s) to secure the wire into the terminal.
Step 6: Insert the red (typical) auxiliary power wire from the pair into a “+” terminal on the
connectors and tighten the screw(s) to secure the wire into the terminal.
Step 7: Replace the connector on the I/O board.
Final Installation
Step 1: Supply power to the unit.
Step 2: Check status indicators for faults.
Status Indicators
When power is applied to the Station Repeater Module, the LEDs located on the front panel illuminate,
indicating the status of the auxiliary power, LinkPower control network, and connected stations.
The Aux Power and LinkPower LEDs indicate in green when the Paradigm station power module is
connected properly and auxiliary power and LinkPower are present. When there is an unbalance in
LinkPower the fault indicators illuminate. This condition typically means that the station wiring has a
fault, however it could mean a connected device is having an issue. A qualified technician should
inspect the system wire and terminations first, then proceed to disconnecting devices to pinpoint the
fault and correct it. The power supply will update the fault indicators automatically when the fault
condition is cleared.
• If the NET A line has a fault (is shorted or has leakage to ground), the Fault + LED lights.
• If the NET B line has a fault (is shorted or has leakage to ground), the Fault - LED lights.
• If neither fault LED is illuminated the data connections are properly installed and the stations are
receiving the data and power required for operation.
