Removing/Replacing a Personality Module
DANGER
Ensure the RTU is in a non-hazardous area. Never open the enclosure in a hazardous area.
DANGER
EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-hazardous.
Performing this operation in a hazardous area could result in an explosion.
DANGER
If replacing a CPU personality module, switch the process this RTU controls over to whatever
manual/backup system you have. If replacing an I/O personality module, switch the associated
I/O to whatever manual control system you have.
1. If you are replacing an existing personality module that is already wired with an identical
personality module, and if there is no fault with the terminal block, leave wiring connected to
the terminal block, and disconnect the terminal block from the personality module by gently
rocking the terminal block from side to side until it pops out. Conversely, if there is a fault
with the terminal block, label wires coming in so you can transfer the wires to the correct
positions on the new terminal block.
