During operation of electrical devices, certain parts of these devices are necessarily under
dangerous voltage.

Ignorance of the safety instructions may result in severe injury or property damage.

Particularly the warning notes in the corresponding Operating Instructions must be strictly
observed.

The modules contain components that are sensitive to electrostatic charge. Always
discharge your body before you touch an electronic module. This can be done quite simply
by touching a conductive, grounded object immediately before you handle the component
(e.g. bright metal parts of the control cabinet, grounding contact of socket outlet.)

Note the regulations/notes on lifting and carrying heavy loads.

Use only a vacuum cleaner and dry cloths to clean the devices.

1.3 Introduction

Electromagnetic compatibility (EMC) is the ability of an electrical device to function, fault-free
in a specified electromagnetic environment without influencing the environment in an
inadmissible fashion.

This design and EMC Directive supplements the documentation on the individual
components.

The SIMATIC TDC control system consists of individual components (e.g. racks, modules,
interface modules, operator control panels, position transmitters). The components can be
installed in the widest range of system configurations to suit individual requirements. In an
environment that contains distributed components it is imperative not to neglect interference
and to conform with special installation and EMC requirements of the plant.

EMC therefore represents a quality feature for

●

variables

●

electromagnetic disturbance variables

●

radiation

The manufacturer of the control system and users (including end customers) must take
specific measures in order to achieve the maximum possible operational reliability and safety
and interference immunity for a complete system (control and drive system).

Proper functioning of SIMATIC TDC can only be ensured if all of these measures have been
observed in compliance with legal provisions (2004/108/EC).

1.6 Low-voltage directive

The products listed in the table below fulfill the requirements of EU directive 2006/95/EC,
"Low-voltage Directive". Compliance with this EC directive was tested in accordance with
DIN 61131-2 (corresponds to IEC 61131-2).

The following components are also affected in SIMATIC TDC:

PS5213 6DD 1683-0CH0

UR6021 6DD 1682-0CH3

These components are compliant with requirements of the Low-voltage Directive.

In accordance with the Machinery Directive 2006/42/EC, it must be ensured that a failure or
malfunction of SIMATIC TDC will not trigger a hazardous state of the machine/plant. This
must always be taken into account when configuring the machine/system.

The system may not be commissioned until it has been proven that the final product is in
compliance with the directive.

Only expert personnel may configure, commission, service and operate SIMATIC TDC.

An external voltage source (e.g. pulse encoder) that is connected to SIMATIC TDC module
inputs must be shut down simultaneously with the shutdown or failure of the SIMATIC TDC
power supply.

SIMATIC TDC components are considered open equipment that must be installed in metallic
enclosures containing shielding and equipotential busbars in compliance with the
requirements of IEC 61131-2 (11.1.2; mechanical strength, flame resistance, stability and
shock protection are significant here).

1.9 Fire protection

As output power exceeds the limit of circuitry with power limiting to IEC 61010-1 /
IEC 61131-2, malfunction of a SIMATIC TDC component may pose the risk of fire according
to IEC 61010-1 / IEC 61131-2. In order to prevent spreading of fire, suitable measures must
be taken to prevent ignition of adjacent parts or components as a result of burning parts that
possibly drop out of a component.

1.13 Power losses in the control cabinet

The dissipation capability of a cabinet and therefore the air intake temperature of the rack
depends on the type of cabinet, on the ambient temperatures and on the internal
arrangement of the devices.

For installation variants 1) and 2), it is presumed that there is a clearance of at least 1 meter
between the top of the control cabinet and the building's ceiling.

Using the SHUTDOWN MODE switch the user can select whether to shut down the rack
immediately on failure of the first fan, or not until an additional fan failure.

TWO / OFF Shutdown is initiated upon the failure of one or more fans

The following notes related to the EMI/EMC measures to take for systems/plants should be
observed in order to avoid disturbance peaks on the supply cables in the cabinet:

The power supply of the rack already has a line filter with sufficient attenuation (refer to
"Manufacturers declaration").

For more demanding applications, you can install an additional line filter (e.g. 250 V AC /
10 A) or overvoltage arrester in the mains line, as close as possible to the cable entry on the
cabinet. Ground of the line filter/arrester must be wired to the equipotential busbar of the
cabinet using the shortest possible conductor length.

60° Centigrade

35° Centigrade

To attenuate external interference, a line filter must be provided for the 24 V power supply of

the digital I/O (e.g. SIFI-B line filter, Order No. B84112-B-.... from Epcos/NF 1-1 line filter of

Phoenix Contact). This filter should be installed as close as possible to the terminal block.
The shield connections of the line filter must be bonded to ground across the shortest
possible distance.

The 24 V power supply must also be equipped with lightning/overvoltage protection.

For more information, refer to the installation manual "SIMATIC Automation Systems
S7-400, Hardware and Installation
(http://support.automation.siemens.com/WW/view/de/1117849/0/en)".

Safe electrical isolation to IEC 61131-2 IEC 61131-2 (11.1.2.1.3) must be ensured for all
power supply units operated on SIMATIC TDC devices and modules.
