Remove the Removable
Terminal Block
If you need to remove the module from the chassis, you must first remove the
RTB from the module.
20854-M
ATTENTION: Shock hazard exists. If the RTB is removed from the module
while the field-side power is applied, the module 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 removing the module.
