Station Connection (Optional)
Sensor3 racks support ETC’s range of stations. The station network should be wired in
Belden 8471 or an equivalent cable. Stations are topology-free. Wiring may be bus, star,
loop, home run or any combination of these.
Connecting Station Wiring
Step 1: Cut the Belden 8471 cable so that a 20cm tail extends from the edge of the
backplane.
Step 2: Strip 18cm of the outer jacket off.
Step 3: Strip 6mm of insulation from the ends of the Belden 8471 wires.
Step 4: Insert the white wire into “STATION +” terminal on the backplane board. Tighten
the screw firmly.
Step 5: Insert the black wire into “STATION -” terminal on the backplane board. Tighten
the screw firmly.
Connect ESD Ground
For installations with data runs of Belden 8471 installed in earthed metal conduit there is no
need to run and terminate an additional ESD drain wire. For installations not installed in
earthed metal conduit, run a 2.5mm
2
ESD drain wire with the Belden 8471 cable. Follow
the instructions below for termination.
Step 1: Locate the earth terminal bar to the right of the rear of the dimmer rack.
Step 2: Strip 6mm of insulation from the ends of the 2.5mm
2
ESD drain wire.
Step 3: Insert the earth wire into an available earth lug and secure with the set screw.
