Electrical Connection¶
The electrical connection is carried out 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 S500 system data chapters Hardware S500.
The serial I/O bus is described in the S500 system data chapter 47413a605a2881ea0a317d3168fd2998.

Caution
:strong:Risk of damaging the PLC modules!
The PLC modules must not be removed when the plant is powered on.
Make sure that all voltage sources (supply and process voltage) are switched off before you are removing or replacing a module.
Note
Analog signals must be laid in shielded cables. The analog cable shield must be only connected on the module side (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 coupled internally with functional earth (FE). Generally 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 the Terminal Base!
The Processor Module and its Terminal Base may be damaged by voltages larger than the range allowed.
Never connect supply and process voltages > 30 V DC.
Attention
:strong:Risk of damaging the Terminal Base and the \ power supply!
Power supply and Terminal Base can be damaged by short circuits.
Make sure that the clamps L+ and M which exist twice are not connected in a wrong way (e. g. +/- of power supply is connected to both L+/L+ or both M/M)
Attention
:strong:Risk of damaging the Terminal Base!
Clamp and Terminal Base can be damaged by too large currents.
Make sure that the current through the spring terminals never exceed 10 A.
