Step 4: Terminate contact / fader interface wires. All field terminations are made to the right side
of the terminal strip.
• When terminating a switch to a Contact Interface, each pair of terminations, either
Switch In or Switch Out, requires one switch and one common connection.
• When terminating a fader input to a Fader Interface, three wires are terminated
including a “PT” connection, “+3.3 Vdc” connection and a “Com” connection.
• When a lamp indication is required for the fader input (Fader Interface only), two
additional wires are required including an “LP” and a common (COM) connection.
Each lamp output terminal is functionally connected to a fader input terminal
(example: PT1 is factory wired and functionally connected to LP1).
a: Strip 7/16” (11mm) from the ends of each wire.
b: Loosen the terminal screw for each required termination.
c: Insert the wires into the corresponding terminal block number and tighten the screws
firmly onto the wires.
N o t e : There is only one +3.3 Vdc terminal and one common (COM) terminal for fader inputs.
When multiple fader inputs are required, each terminal allows up to eight wires in the
single terminal. Additional connections can be bussed together to share the line using
WAGO connectors as required.
N o t e : The lamp voltage conducts from “V out” to the lamp outputs. When using polarity
sensitive indicators such as an LED, connect the anode to “V out” and the cathode to
the lamp “LP” connection.
