Installing the terminal block

Introduction
The slots are created by the connection of the carrier modules to the terminal blocks for the I/
O modules when the IO device is installed.
Requirements
Note
Installing teminal blocks for individual I/O modules and for IO redundancy in an IO device
Only terminal blocks for individual I/O modules or for IO redundancy may be plugged in a
potential group.
The carrier modules must be screwed in.
● The carrier module for the I/O modules is mounted.
You can find information on this in the section "Mounting an carrier module for I/O module
slots (Page 68)".
● The requirements of the plant were taken into consideration when selecting the terminal
blocks.
You can find information on this in the section "Selecting a terminal block for I/O modules
(Page 32)".
● Terminal blocks must be completely installed on an carrier module.
45 millimeter wide terminal blocks (TB45... - terminal blocks for I/O-redundancy or potential
distributors) :
● The terminal blocks (TB45...) must be plugged into the slots of the carrier module beginning
with odd slot numbers.
● The terminal blocks (TB45...) may not be plugged over two adjacent carrier modules.
Figure 5-3
Slots for modules on terminal block for IO redundancy (TB45R...)
● The slots for modules in IO redundancy are located on the same terminal block (TB45R).
● The I/O modules of the same type have to be placed in pairs, side-by-side in the same IO
device.
