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.

WARNING

Verify that all incoming power is turned off before wiring power to the LIM
module or any other devices in this chapter.
