Connecting Wires to Terminal Block Connectors
Connect wires to terminal block connectors as follows:
1. To connect a wire, find the correct terminal and loosen the screw over it by turning it
counterclockwise (see Figure 2-2).
2. Strip the correct wire for this terminal 1/4 in. (6.4 mm) from end.
3. Insert bare wire into the terminal 90% of the way. Tighten the screw. The metal tooth
inside will clamp down on the bare wire for a tight connection. Make sure that the metal
tooth is clamped down on the bare part of the wire, not on the insulation.
4. Connect all wires. Double-check connections when done.
5. Plug the connector firmly into the receptacle on the PC board. The connector can fit into
the receptacle in only one direction.
Terminating Cable Shields
Your SmartPAC 2 has ground studs on the inside of the enclosure for terminating cable
shields at their point of entry.
CONNECTOR WIRING
The connector can plug into the receptacle on the PC board in only one direction. Before wiring
the connector, mark its left and right ends when it is plugged in to make sure you wire the correct
pin numbers.

TERMINATE BOTH ENDS OF SHIELD
