Nexus – How do I wire the trigger/input signals with an
isolated neutral?
A short guide on how to wire the tigger/input signals for your Nexus unit with a common isolated connector
Step 1

The Trigger Signals are located inside the unit on the right side board. If you are looking to wire Isolated Input trigger signals with a Isolated Neutral‘s use the 9 way A & B rail shown here.
Step 2
Wire both the A & B rail connectors with the trigger signal and corresponding isolated neutral connector, the trigger number and neutral highlight below. For example:
Trigger connector slot 1 neutral is slot 1 on the – or B rail.
Trigger connector slot 3 neutral is slot 3 on the – or B rail.

Step 3

Place the Isolated Neutral connector back into the two way slot shown below.
Step 4
Connect any Isolated trigger signals into the A rail as shown.

Step 5

Confirm that any Isolated Neutral connections have the Dip Switches in the TOP position.
Step 6
The last step is to define if the trigger signals are HIGH or LOW. High are for voltages between 110-240 volts. Low is for voltages between 12-24 volts.
