Connect Wiring
The 0–10V Dimming Control option card provides four
bus connections for termination of six 0–10 V outputs
each (24 channels). A pluggable screw-terminal
connector is provided for each bus, and is labeled for
ease of identification of each output. The removable
connectors accept 0.25–4 mm
Note:
By default, the associated output loop terminal number matches the relay
circuit number inside the relay panel. For example, if relay 1 is connected to a 4-wire
fluorescent dimmer, ballast control wiring would terminate to the output terminals
labeled "+ 1 -" on the 0–10 V Dimming Control option card.
To customize the links between relay and 0–10 V control, see the Power Control
Processor Mk2 Configuration Manual .
Note:
See the white paper Understanding 0-10V LED Drivers for Class 2 and Class 1
wiring considerations.
1. Pull 0–10 V ballast control wiring pairs into the relay panel according to the wire entry plan.
See
Cable Routing and Conduit Access on page 13
information.
2. Strip the insulation from each wire pair back 6 mm (1/4 in).
3. Remove the pluggable screw connector for the 0–10 V output bus that matches the relay
circuit.
4. Notice that the connector is labeled for your wire termination reference. Using a 3 mm
(1/8 in) flatblade screwdriver, loosen the terminals and insert each of the data + and data -
wire set into the appropriate terminal for the circuit.
a. Terminate the violet (typical) control wire of the first pair into the "+" terminal
associated with the power circuit.
b. Terminate the gray (typical) control wire of the first pair into the "-" terminal associated
with the power circuit.
Note:
together.
c. Tighten each screw terminal until the wire is secure.
5. Repeat steps 1–4 for the remaining 0–10 V outputs in the panel.
