Install the Removable
Terminal Block

These steps show how to install the RTB onto the module to connect the wiring.

Before installing the RTB, verify the following:

Field-side wiring of the RTB is complete.

The RTB housing is snapped into place.

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.

WARNING: When you connect or disconnect the removable terminal block
(RTB) with field-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 nonhazardous before proceeding.

ATTENTION: Shock hazard exists. If the RTB is installed onto the module
while the field-side power is applied, the RTB will be electrically live. Do not
touch the RTB’s terminals. Failure to observe this caution may cause personal
injury.

The RTB is designed to support Removal and Insertion Under Power (RIUP).
However, when you remove or insert an RTB with field-side power applied,
unintended machine motion or loss of process control can occur. Exercise extreme
caution when using this feature. We recommend that field-side power be removed
before installing the RTB onto the module.
