Installing 24 VDC Connectors

Use the supplied connector to connect the user-supplied 24 VDC power supply to the
SmartController EX motion controller.
1. Locate the 24 VDC connector shipped with the controller. See the following figure.
2. Use 14 or 16 gauge wire to connect the 24 VDC power supply to the controller.
3. Strip 7 mm of insulation from the end of the wire that connects to the positive output of
the 24 VDC supply.
4. Insert the stripped end into the opening on the right side of the connector.
5. Tighten the screw clamp on the connector with a small slot screwdriver (2.5 mm).
6. Visually inspect the connection to ensure that the clamp has closed on the wire, not on
the insulation.
7. Gently pull on the wire to confirm that it is securely attached to the connector.
8. Repeat this process to connect the wire from the negative side of the power supply to
the left side of the connector.
9. Connect the braided shield to the ground screw on the front of the controller.
A ring lug can be used, as shown in the following figure. The ground screw is an M3.
