The operator of a machine system is responsible for observing all
safety and accident prevention regulations applicable to the application in
question.
During configuration, safety and accident prevention rules specific
to the application must be observed.
Emergency OFF facilities according to EN 60204 / IEC 204 must
remain active in all modes of the machine system. The system must not
enter an undefined restart.
Faults occurring in the machine system that can cause damage to
property or injury to persons must be prevented by additional external
equipment. Such equipment must also ensure entry into a safe state in the
event of a fault. Such equipment includes, for example, electromechanical
safety buttons, mechanical interlocks, etc. (see EN 954-1, risk estimation).
Never execute or initiate safety-related functions using the
modules.

2Mounting
2.1 Foreword
This section describes planning of mechanical assembly, preparation
of components for mounting, and final mounting itself.
2.2 Restriction of access
The DEA 300 module must be installed according to VDE 0100
IEC 364. The modules are open equipment and must only be
installed in electrical equipment rooms, cabinets, or housings.
Access to the electrical equipment rooms, barriers, or housings must
only be possible using a tool or key and only permitted to personnel
having received instruction or authorization. See also 1.6.
2.3 Planning assembly
Permissible surrounding air temperature:
•for vertical mounting: from 0 to +40 ºC
•for horizontal mounting: from 0 to +60 ºC
The modules can be
mounted either vertically
or horizontally.
Fig. 2-1:
Vertical and horizontal
mounting
Only authorized persons
must have access to the
modules!

11 DEA 300
2.4 Minimum clearance
Minimum clearances must be observed because
•it ensures cooling of the DEA 300 modules
•it provides space to insert and remove modules
•it provides space to route cables
•it increases the mounting height of the module rack to 185 mm,
although the minimum spacing of 40 mm must still be observed
Fig. 2-2 shows the minimum spacing between the module racks and
between these and any adjacent cabinet walls, equipment, cable
ducts, etc. for DEA 300s mounted in several module racks.
2.5 Mounting of the modules on the DIN rail
Sectional rail 700-390-1xxxx length see chapter 5 Ordering data.
A bus connector is included with each signal module but not with
the CPU. When connecting the bus connector, always start with the
CPU.
Take the bus connector off the last module and insert it into the
CPU. Do not plug a bus connector into the last module of the tier.
Fig. 2-2:

mounting
Non
-observance of the
minimum distances can
destroy the module at
high surrounding air
temperature!

3Wiring
3.1 Protection from external electric interference
On all systems and plants in which the DEA 300 modules are
installed, it is important to ensure that the system or plant is
connected to a protective ground conductor to remove
electromagnetic interference.
Makes sure that all supply, signal, and bus cables are correctly
installed and that cable routing is correct.
Make sure, for all signal and bus cables, that a conductor or cable
break cannot cause undefined states of the system or plant.
3.2 Current consumption and power loss
DEA 300 modules draw the power they require to operate from the
backplane bus. Where required, they can be powered from an
external source.
•The total current consumption of all signal modules drawn from
the backplane bus must not exceed the current the CPU can
supply to the backplane bus.
•The power loss of all modules used in a cabinet must not exceed
the maximum cabinet power that can be dissipated.
For information about current consumption and power loss of a
module, see the technical data of the module in question.
3.3 Mounting isolated modules
In an assembly containing isolated modules, the reference potentials
of the control circuit (GND internal) and the external load circuit
(GND external) are mutually isolated.
Isolated modules are used for DC load circuits with a separate
reference potential.
Examples of load circuits with a separate reference potential:
•DC load circuits whose sensors have different reference potentials,
for example, if grounded sensors are used at a great distance from
the controller making equipotential bonding between them
impossible.
•DC load circuits, whose plus pole (L +) is grounded.
When dimensioning the
cabinet make sure the
temperature in the
cabinet does not
exceed
60 °C even if the outside
temperature is high.
Isolated modules can be
used irrespective of
whether the reference
potential of the
controller is grounded or
not.

DEA 300 14
3.4 Outdoor cable laying
•The same guidelines apply as for indoor cable laying.
•The cables must be laid on metal cable trays.
•Joints between cable trays must be conductively connected.
•Cable trays must be grounded.
•Adequate equipotential bonding between connected devices must
also be ensured.
•Interior and exterior lightning protection must be ensured and
such grounding measures must be taken as are suitable for the
application in question.
3.5 Protection from inductive overvoltages
The DEA 300 digital output modules feature integrated overvoltage
protection. Overvoltages arise when inductors are switched off, for
example, relay solenoids and contactors.
Inductors only have to be provided with additional overvoltage
protection if:
•the outputs can be switched off by additional built-in contacts,
such as relay contacts.
•the inductors are not controlled by the modules.
Fig. 3-2 shows an example of an output circuit requiring additional
overvoltage protection.
Lighting protection must
always be based on an
individual assessment of
the overall plant.
The inductor supplier
will provide information
about the dimensioning
of overvoltage protection
equipment.
