Electrical Connection¶
The electrical connection is set up using the terminals of the TF5x1_CMS.
Note
Mounting, disassembling and electrical connection for the terminal function block and the I/O Modules are described in the system assembly chapter, as well as the serial I/O bus System Assembly, Construction and Connection.

Caution
:strong:Risk of damaging the PLC modules!
The PLC modules must not be removed while the plant is connected to a power supply.
Make sure that all voltage sources (supply and process voltage) are switched off before you remove or replace a module.
Note
Analog signals must be transmitted through shielded cables. The analog cable shield must only be connected to the side of the module (SH terminals) to avoid relaxation currents influencing the measuring results and for optimal robustness against external noise. The shield connection must be as short as possible (< 3 cm). The analog shield is capacitive and internally coupled with the functional earth (FE). To avoid unacceptable potential differences between different parts of the installation, low-resistance equipotential bonding conductors must be laid .
Caution
:strong:Risk of damaging the processor module and terminal base!
Voltages surpassing the permitted range might damage the processor module and terminal base.
Never connect supply and process voltages > 30 V DC to the terminal base.
Attention
:strong:Risk of damaging the terminal base and power supply!
Short circuits might damage the terminal base and power supply.
Make sure that the four clamps L+ and M (two of each) are not wrongly connected (e. g. +/- of power supply is connected to both L+/L+ or both M/M)
Attention
:strong:Risk of damaging terminal base!
Excessive current might damage the clamp and terminal base.
Make sure that the current flowing through the spring terminals never exceeds 10 A.
