Chapter 1 Prepare the CompactLogix Hardware
Mount and Wire the Line Interface Module
2094-AL75S or Equivalent Hardware, Required for EtherNet/IP and DeviceNet Systems
The line interface module (LIM) serves as the power connection and the generation point for
the complete power needs of most control panels. The LIM module provides the control of
three-phase power and the drive logic power, and also serves as the source and circuit
protection of power for the controller, I/O, and other panel devices. A single LIM module
can replace nine individual components, eliminating up to 100 interconnecting wire
terminations. The 2094-AL75S line interface module (LIM) is optional. Individual
components can be purchased separately instead of purchasing the LIM.
1. Lay out the position of
the LIM module in the
enclosure.
2. Attach the LIM module
to the cabinet by using
M6 (1/4 in.) bolts.
3. Tighten all mounting
fasteners.
4. Mount the
through-the-door
disconnect switch for the
LIM module.
5. Wire 230V 3-phase
incoming power to the
LIM module and
6. Bond the ground
terminal to the panel.
Verify that all incoming power is turned off before wiring power to the LIM
module or any other devices in this chapter.
