Replacing the terminal block connector
It is important to use the correct terminal block for your module. Refer to the tables below
and your module specifications to determine the correct terminal block replacement.
Note
Keyed removable terminal blocks
PLCs always require correct wiring to ensure safety and proper operation.
When replacing the terminal block in your CPU or SM, it is important that you use the correct
terminal block and correct wiring source for your module.
The keyed feature helps prevent you from accidentally placing a high voltage wired terminal
block into a low voltage module, or from placing a special voltage wired terminal block into a
normal voltage module. Some terminal blocks are specifically keyed at left, at right or at
middle.
