3. If the Model 3300 or the Model 3500 has I/O cables, plug the bracketed wiring
connector onto the terminal strips on the back panel of the model. See
Figure 3-3
.
4. Tighten the captive screws to secure the bracket to the back panel.

5. Attach the supplied I/O terminal block to a DIN rail.
The terminal block fits various rail types. See
Figure 3-4
.
6. Plug the connector for input/output wiring onto the I/O terminal block.
7. Tighten the captive screws to secure the connector to the I/O terminal block.
8. Connect input and output wiring to the appropriate terminals on the I/O terminal
block.
