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 removing the module.
