Identify the Module Components

You received the following components with your order:

1756-IF4FXOF2F module

Removable Terminal Block (RTB) door label

If you did not receive these components, contact your local 
distributor Rockwell Automation sales office.

This module mounts in a ControlLogix

 chassis and uses a 

separately-ordered RTB or a Bulletin 1492 Interface Module (IFM) to 
connect all field-side wiring. 

This module uses one of the following RTBs:

1756-TBCH 36 position Cage clamp RTB

1756-TBS6H 36 position Spring clamp RTB

Use an extended-depth cover (1756-TBE) for applications with heavy 
gauge wiring or requiring additional routing space. When using an 
IFM, consult the documentation that came with it to connect
all wiring.

IMPORTANT

Before you install your module, you should
have already:

installed and grounded a 1756 chassis and 
power supply.

ordered and received an RTB or IFM and its 
components for your application.
