Wiring the Dry Contact Connector
Wiring instructions for dry contact wiring for SELV devices is included in this
section. The dry contact connector is intended to control the trigger of SELV
devices such as small DC fans or external AC or DC relays. It does not provide
power to the Conext ComBox.
To wire the dry contact connector:
1. Strip 3/8 in. (10 mm) from the end of the wire to be connected and attach
ferrules to the bare wires.
2. Insert the ferrule into the Dry Contact connector’s wire terminal.
3. Secure the wire by tightening the screw on the terminal.
4. Repeat steps 2 and 3 for the remaining wires.
5. Once all the Dry Contact wires are secured, push the Dry Contact connector
into the Dry Contact port until it locks into place.
6. Go to “Connecting the Conext ComBox to an Ethernet Network”.
DANGER
