Identify the Module Components
You received the following components with your order: • 1756-IF6I module • Removable Terminal Block (RTB) door label If you did not receive these components, contact your 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-TBNH 20 position NEMA RTB • 1756-TBSH 20 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. Before you install your module, youshould have already: • installed and grounded a 1756 chassis and power supply. • ordered and received an RTB or IFM and its components for your application.

Prevent Electrostatic Discharge

Electrostatic discharge can damage integrated circuits or semiconductorsif you touch backplane connector pins. Follow these guidelines when you handle the module: • Touch a grounded object to discharge static potential. • Wear an approved wrist-strap grounding device. • Do not touch the backplane connector or connector pins. • Do not touch circuit components inside the module. • If available, use a static-safe work station. • When not in use, keep the module in itsstatic-shield box.


Removal and Insertion Under Power (RIUP)


This module is designed so you can remove and insert it under backplane power and field-side power. When you remove or insert a module while field-side power is applied, you may cause an electrical arc. An electrical arc can cause personal injury or property damage because it may: • send an erroneous signal to yoursystem’s field devices, causing unintended machine motion or loss of process control. • cause an explosion in a hazardous environment. Repeated electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance. When you insert or remove the module while backplane power is on, or you connect or disconnect the RTB withfield-side power applied, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is non-hazardous before proceeding.
