Follow these steps to install the RTB onto the module to connect the
wiring.

WARNING: When you connect or disconnect the removable
terminal block (RTB) with field-side power applied, an electric arc
can occur. This could cause an explosion in hazardous location
installations.

Be sure that power is removed or the area is nonhazardous before
proceeding.

Before installing the RTB, verify the following:

• Field-side wiring of the RTB is complete.

• The RTB housing is snapped into place on the RTB.

• The RTB housing door is closed.

• The locking tab at the top of the module is unlocked.

1. Align the top, bottom, and left side guides of the RTB with the
guides on the module.

Recommendations for Wiring Your RTB

We recommend that you follow these guidelines when wiring your
RTB :

• Begin wiring the RTB at the bottom terminals and move up.

• Use a tie to secure the wires in the strain relief (bottom) area of
the RTB.

• Order and use an extended-depth housing (catalog number
1756-TBE) for applications that require heavy gauge wiring.

Assemble the RTB and the Housing

A removable housing covers the wired RTB to protect wiring
connections when the RTB is seated on the module.

1. Align the grooves at the bottom of each side of the housing
with the side edges of the RTB.

6 Rockwell Automation Publication 1756-IN062A-EN-P - August 2017

2. Press quickly and evenly to seat the RTB on the module until
the latches snap into place.

3. Slide the locking tab down to lock the RTB onto the module.
