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

The Trigger Signals are located inside the unit on the right side board. If you are looking to wire Common Input trigger signals with a Common Neutral use the 2 way connector and 9 way A rail shown here.
Step 2
Wire the Common Neutral into the two way and connect your Trigger Connections into slots 1-8 in the 9 way connector as required.

Confirm that the Dip switches are in the BOTTOM position for the Common Neutral.
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.
