Safety Considerations
This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D or
non-hazardous locations only.
See Safety Considerations
on page 20 for additional information.
Install and Attach the AIC+
1. Take care when installing the AIC+ in an enclosure so that the cable
connecting the MicroLogix controller to the AIC+ does not interfere with
the enclosure door.
2. Carefully plug the terminal block into the RS-485 port on the AIC+ you
are putting on the network. Allow enough cable slack to prevent stress on
the plug.
3. Provide strain relief for the Belden cable after it is wired to the terminal
block. This guards against breakage of the Belden cable wires.
