2.4 Measures
Distributed I/O device 6DL2804-xxxxx
8Hardware Installation Manual, 03/2014, A5E00378896F-03
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 certification as soon as they are operated on circuits
which do not correspond with the test certification 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.

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 specifies the degree of protection
for which the enclosure is designed. The minimum degrees of protection are:
●Device group I: IP54/IP55
●Device group II: IP54 to IP66 (Zones 1 + 2)
●Device group II: IP64 to IP66 (Zones 21 + 22)
Operating temperature
The operating temperature range of the enclosure depends on the temperature range of the
parts used, and can differ from the actual operating temperature range:
●-40 °C to +75 °C: only for the enclosure versions 6DL2804-0xxx1
●0 °C to +75 °C
The nameplate specifies the permissible operating temperature range in each case.
●Prior to installation of components, check the operating temperature range of the
complete setup. The operating temperature range for the complete setup may be limited
by the maximum permissible operating temperature of the components and the
dissipated heat produced in the enclosure.
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. Delivery of enclosures with appropriate surface protection is
possible for use with aggressive environmental conditions.

Cable and wiring entries (CWE)
●When fitting 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 specifications, refer the respective manufacturer
documentation, in particular:
–Technical specifications, 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.
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. In cases where the ground and equipotential bonding conductors are installed
separately, this connection can be disconnected.
Note
Also observe the installation guidelines in the ET200iSP operating instructions, Section 5.2
"Using ET 200iSP with equipotential bonding".
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/M8 ground connection screw is used for the PE conductor; use a cable with lug for
this. To prevent the screw from becoming loose, make sure you use the lock washer.
Connecting the grounding cable avoids static charge which is important, in particular, for
dust explosion protection.

Installed components
The enclosure nameplate specifies the parameters within which the installed components
can be used.
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.

for the relevant hazardous zone.
•Run the tests prescribed in the relevant national regulations for the installed control and
measuring devices.
Note
•Install and operate the distributed I/O device in hazardous areas according to the
specifications of the EC-type examination certificate according to ATEX and these
operating instructions or the standards and directives valid in your country.
•Assembly, installation, commissioning and maintenance may only be performed by
qualified personnel.

4.1
Transport and storage
Pack and store the enclosure for transport or storage so that there can be no undue strain on
the enclosure, particularly on its top cover. If there is too much strain on the top cover of the
enclosure, this can damage the seal.
Do not place the enclosure on the cable glands fitted in its base, otherwise the glands will be
damaged.
4.2
Mounting the enclosure
The enclosure is intended for wall mounting and should be secured with the wall supports
supplied with it. Use the following template for the drilling.
Figure 4-1 Drilling template for securing the device
CAUTION
Danger of injury when the enclosure is opened
When opening the enclosure with pivoting cover, the cover is pressed upwards by means of
the pressure of the dampers. When opening, press against the cover with your hand.
Note
•Remember the maximum thermal load on the cables and wiring. The degree of protection
is only ensured when suitable cables and wires are used and correctly installed.
•Note that it is only permitted to connect and disconnect the cables to the power supply
module if the module has been powered down.
•The degree of protection is reduced when the enclosure is mounted vertically.
