Fitting a screw terminal block to a Discrete I/O module.

All Premium Discrete I/O modules with screw terminal block connection require the latter to be connected to the module. Fitting operations (assembly and disassembly) are described in the following table.
Assembly/Disassembly
The following table shows the procedure for assembling the screw terminal block onto a Discrete I/O module.
Step
Action
Illustration
1
With the module in position in the rack, place the terminal block on the module as shown opposite.
Step 1 and 2
2
Pivot the terminal block so as to bring it to the engaged position on the module.
3
Tighten the fastening screws of the upper section of the terminal block so as to firmly attach the terminal block to the module (torque setting: 2.0 N.m).
Step 3
Note:
The first time a screw terminal block is mounted on a module which takes this type of connection, the terminal block is coded according to the type of module on which it is assembled. Coding is performed by transferring two encoded pins from the module to the terminal block. This mechanical coding then inhibits any use of the terminal block with a different module type.
The code is transferred automatically during step 1.
