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 2-3 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 1200 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.
Apply Power to the AIC+
In normal operation with the MicroLogix 1200 programmable controller
connected to port 2 of the AIC+, the controller powers the AIC+. Any AIC+
not connected to a controller requires a 24V dc power supply. The AIC+
requires 120 mA at 24V dc.
If both the controller and external power are connected to the AIC+, the
power selection switch determines what device powers the AIC+.
WARNING
EXPLOSION HAZARD
AIC+ must be operated from an external power
source.
This product must be installed in an enclosure. All
cables connected to the product must remain in the
enclosure or be protected by conduit or other
means.
ATTENTION
If you use an external power supply, it must be
24V dc (-15%/+20%). Permanent damage results if a
higher voltage supply is used.
