Security information 1
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is necessary
to implement – and continuously maintain – a holistic, state-of-the-art industrial security
concept. Siemens’ products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected to
an enterprise network or the internet if and to the extent such a connection is necessary and only
when appropriate security measures (e.g. 󹪝rewalls and/or network segmentation) are in place.
For additional information on industrial security measures that may be implemented, please
visit
https://www.siemens.com/industrialsecurity.
Siemens’ products and solutions undergo continuous development to make them more secure.
Siemens strongly recommends that product updates are applied as soon as they are available
and that the latest product versions are used. Use of product versions that are no longer
supported, and failure to apply the latest updates may increase customer’s exposure to cyber
threats.

2.4 Measures
In the interest of safety, observe the following precautionary measures:
WARNING
Type of protection "Flameproof enclosure d"
Devices with "pressure-resistant encapsulation" protection may only be opened when the
power has been disconnected.
Type of protection "Intrinsic safety i"
"Intrinsically-safe" devices lose their certi󹪝cation as soon as they are operated on circuits which
do not correspond with the test certi󹪝cation valid in your country.
Type of protection "Increased safety e"
Devices with the type of protection "Increased safety" must not produce sparks or electric arcs
during operation under normal conditions. Electrical equipment and parts must not exceed a
rated voltage of 11 kV.
Type of protection "Mold encapsulation m"
Devices with the type of protection "Mold encapsulation" are potted in casting compound.
Type of protection "By means of enclosure t"
Devices with the type of protection "By means of enclosure" prevent the penetration of dust or
reduce it to a harmless level. Explosive equipment can be installed. The temperature on the
housing must not ignite the surrounding atmosphere.
WARNING
Use in environments with aggressive and dangerous media
The device can be operated both at high pressure and with aggressive and hazardous media.
Therefore, improper use of this device may lead to serious injury and or considerable damage
to property. Above all, it must be noted when the device was in use and is to be exchanged.
CAUTION
Electrostatic sensitive devices
This device contains electrostatic sensitive devices. ESD devices can be destroyed by voltages
well below the threshold of human perception. These static voltages develop when you touch
a component or electrical connection of a device without having discharged the static charges
present on your body. The damage to a module as a result of overvoltage cannot usually be
detected immediately. It may only become apparent after a long period of operation.

4.6 Details of the enclosure
Degree of protection
The degree of protection depends on the enclosure size and the parts used such as cable entries,
dummy plugs and climate nozzles. The nameplate speci󹪝es the degree of protection for which
the enclosure is designed. The minimum degrees of protection are:
• Device group II: IP54 to IP66 (Zone 1)
• Device group II: IP64 to IP66 (Zone 21)
Operating temperature
The operating temperature range of the enclosure depends on the temperature range of the
parts used, and can di󹪜er from the actual operating temperature range:
• -40°C to +75 °C
The nameplate speci󹪝es the permissible operating temperature range in each case.
• The maximum permissible operating temperature of the components and the power
dissipation occurring in the enclosure may limit the ambient temperature range for the total
con󹪝guration. This is checked at the factory for each cabinet. This calculation may di󹪜er from
the results of the TIA Selection Tool, since reserve modules are also taken into account.
Climate nozzles provide pressure compensation and drainage in the event of varying climatic
conditions.
• In the case of aggressive environments, check whether use of the enclosure is possible with
the material in question.
Cable and wiring entries (CWE)
• When 󹪝tting cables, observe the manufacturer's data on the tightening torques of the cable
and wiring entries.
• Use the tightening torque of the clamping screw when connecting the cables.
• Relieve the tension on the cables outside the enclosure so that the cable gland is not stressed.
• For additional information and technical speci󹪝cations, refer the respective manufacturer
documentation, in particular:
– Technical speci󹪝cations, clamping ranges for cables
– Notes on use, installation, mounting, commissioning and maintenance
Note
Use the supplied red dummy plugs to close any cable glands not in use. Only then is it ensured
that the degree of protection is retained.

Wall-mount enclosure 6DL2804-0xxxx
Hardware Installation Manual, 08/2022, A5E42024593-AB 19

Equipotential bonding rail
The equipotential bonding rail (10 x 3 mm) with terminals (up to 4 mm²) is used to contact the
cable shields. Alternatively, you can also use other terminals here, e.g. KLBüCo from the
company Weidmüller (not included in the scope of delivery)
Connect the equipotential bonding wire to the bonding terminal (0.75 to 35 mm²).
Short lines connect the equipotential bonding rail to the mounting plate and thus to the
enclosure.
Note
Also refer to the installation guidelines in the SIMATIC ET 200iSP Operating Instructions, section
5.2 "Operating the ET 200iSP with potential equalization".
Wall supports
Screw the wall supports onto the enclosures using M6/M8 screws depending on the enclosure
size. These are included with the enclosure accessories. To secure the enclosure, use 8 mm
diameter screws and lock washers.
Grounding connection
The M6 ground connection screw is used to connect the ground cable. Use a cable with cable lug
for this purpose. To prevent the screw from becoming loose, make sure you use the lock washer.
Connecting a ground cable prevents static charging.
Installed components
Observe the following if you subsequently connect equipment and the required cables on site:
• Read and observe the manufacturer's instructions, especially notes, warnings and
information on special features.
• Electrical equipment as well as combinations of equipment can impair the intrinsic safety of
the circuits as a result of their electrical parameters. Prior to installing equipment, check that
the intrinsic safety of the circuit is still guaranteed.
Note
If you want to replace ET 200iSP reserve modules with ET 200iSP modules, please contact
Siemens regarding the rated current and power loss calculation.
