3-10 Installing the Sequence of Events Module
Installing the Removable
Terminal Block Install the RTB onto the module to connect wiring.
Before installing the RTB, make certain:
• field-side wiring of the RTB has been completed.
• 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.
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. It is
recommended that field-side power be removed
before installing the RTB onto the module.
