Safety Notes
1.5 Safety Notes
Attention
Switch off the system prior to working on bus modules!
In the event of deformed contacts, the module in question is to be replaced, as
its functionality can no longer be ensured on a long-term basis.
The components are not resistant against materials having seeping and insulating properties. Belonging to this group of materials is: e.g. aerosols, silicones, triglycerides (found in some hand creams).
If it cannot be ruled out that these materials appear in the component environment, then additional measures are to be taken:
- installation of the components into an appropriate housing
- handling of the components only with clean tools and materials.
Attention
Cleaning of soiled contacts may only be done with ethyl alcohol and leather
cloths. Thereby, the ESD information is to be regarded.
Do not use any contact spray, as in a worst-case scenario; the functioning of
the contact area can be impaired.
The WAGO-I/O-SYSTEM 750 and its components are an open system. It
must only be assembled in housings, cabinets or in electrical operation
rooms. Access must only be given via a key or tool to authorized qualified
personnel.
The relevant valid and applicable standards and guidelines concerning the
installation of switch boxes are to be observed.
ESD (Electrostatic Discharge)
The modules are equipped with electronic components that may be destroyed
by electrostatic discharge. When handling the modules, ensure that the environment (persons, workplace and packing) is well grounded. Avoid touching
conductive components, e.g. gold contacts.

System Description
2 The WAGO-I/O-SYSTEM 750
2.1 System Description
The WAGO-I/O-SYSTEM 750 is a modular, fieldbus independent I/O system.
It is comprised of a fieldbus coupler/controller (1) and up to 64 connected
fieldbus modules (2) for any kind of signal. Together, these make up the
fieldbus node. The end module (3) completes the node.
Fig. 2-1: Fieldbus node
g0xxx00x
Couplers / controllers for fieldbus systems such as PROFIBUS, INTERBUS,
ETHERNET TCP/IP, CAN (CANopen, DeviceNet, CAL), MODBUS, LON
and others are available.
The coupler / controller contains the fieldbus interface, electronics and a
power supply terminal. The fieldbus interface forms the physical interface to
the relevant fieldbus. The electronics process the data of the bus modules and
make it available for the fieldbus communication. The 24 V system supply and
the 24 V field supply are fed in via the integrated power supply terminal.
The fieldbus coupler communicates via the relevant fieldbus. The programmable fieldbus controller (PFC) enables the implementation of additional PLC
functions. Programming is done with the WAGO-I/O-PRO 32 in accordance
with IEC 61131-3.
Bus modules for diverse digital and analogue I/O functions as well as special
functions can be connected to the coupler / controller. The communication
between the coupler/controller and the bus modules is carried out via an internal bus.
The WAGO-I/O-SYSTEM 750 has a clear port level with LEDs for the status
indication, insertable mini WSB markers and pullout group marker carriers.
The 3-wire technology supplemented by a ground wire connection allows the
direct sensor/actuator wiring.

Storage, Consignment and Transport
2.4 Storage, Consignment and Transport
Wherever possible, the components are to be stored in their original packaging. Likewise, the original packaging provides optimal protection during
transport.
When consigning or repacking the components, the contacts must not be
soiled or damaged. The components must be stored and transported in appropriate containers/packaging. Thereby, the ESD information is to be regarded.
Statically shielded transport bags with metal coatings are to be used for the
transport of open components for which soiling with amine, amide and silicone has been ruled out, e.g. 3M 1900E.
2.5 Mechanical Setup
2.5.1 Installation Position
Along with horizontal and vertical installation, all other installation positions
are allowed.
Attention
In the case of vertical assembly, an end stop has to be mounted as an additional safeguard against slipping.

Mechanical Setup
2.5.3 Assembly onto Carrier Rail
2.5.3.1 Carrier rail properties
All system components can be snapped directly onto a carrier rail in accordance with the European standard EN 50022 (DIN 35).
Warning
WAGO supplies standardized carrier rails that are optimal for use with the
I/O system. If other carrier rails are used, then a technical inspection and approval of the rail by WAGO Kontakttechnik GmbH must take place.
Carrier rails have different mechanical and electrical properties. For the optimal system setup on a carrier rail, certain marginal terms must be observed:
·
The material must be non-corrosive.
·
Most components have a contact to the carrier rail to ground electro-magnetic disturbances.
In order to avoid corrosion, this tin-plated carrier rail contact must not form a galvanic cell
with the material of the carrier rail which generates a differential voltage above 0.5 V (saline
solution of 0.3% at 20°C) .
·
The carrier rail must optimally support the EMC measures integrated into the system and the
shielding of the bus module connections.
·
A sufficiently stable carrier rail should be selected and, if necessary, several assembly points
(every 20 cm) should be used in order to prevent bending and twisting (torsion).
·
The geometry of the carrier rail must not be altered in order to secure the safe hold of the
components. In particular, when shortening or mounting the carrier rail, it must not be
crushed or bent.
·
The base of the components extends into the profile of the carrier rail. For carrier rails with a
height of 7.5 mm, assembly points (screws) are to be riveted under the node in the carrier rail
(slotted head captive screws or blind rivets).

2.5.4 Spacing
The spacing between adjacent components, cable conduits, casing and frame
sides must be maintained for the complete field bus node.
Fig. 2-4: Spacing

The spacing creates room for heat transfer, installation or wiring. The spacing
to cable conduits also prevents conducted electromagnetic interferences from
influencing the operation.

2.5.5 Plugging and Removal of the Components
Warning
Before work is done on the components, the voltage supply must be turned
off.
In order to safeguard the coupler/controller from jamming, it should be fixed
onto the carrier rail with the To do so, push on the upper groove of the locking disc using a screwdriver.
To pull out the fieldbus coupler/controller, release the locking disc by pressing
on the bottom groove with a screwdriver and then pulling the orange colored
unlocking lug.

Mechanical Setup
2.5.6 Assembly Sequence
All system components can be snapped directly on a carrier rail in accordance
with the European standard EN 50022 (DIN 35).
The reliable positioning and connection is made using a tongue and groove
system. Due to the automatic locking, the individual components are securely
seated on the rail after installing.
Starting with the coupler/controller, the bus modules are assembled adjacent to
each other according to the project planning. Errors in the planning of the node
in terms of the potential groups (connection via the power contacts) are recognized, as the bus modules with power contacts (male contacts) cannot be
linked to bus modules with fewer power contacts.
Attention
Always link the bus modules with the coupler / controller, always plug from
above.
Warning
Never plug bus modules from the direction of the end terminal. A ground
wire power contact, which is inserted into a terminal without contacts, e.g. a
4-channel digital input module, has a decreased air and creepage distance to
the neighboring contact in the example DI4.
Always terminate the fieldbus node with an end module (750-600).

contacts.
Fig. 2-7: Data contacts
p0xxx07x
Warning
Do not connect the I/O module to gold spring contacts in order to avoid soiling or scratches!
ESD (Electrostatic Discharge)
The modules are equipped with electronic components that may be destroyed
by electrostatic discharge. When handling the modules, ensure that the environment (persons, workplace and packing) is well grounded. Avoid touching
conductive components, e.g. gold contacts.

2.5.8 Power Contacts
Self-cleaning power contacts , are situated on the side of the components
which further conduct the supply voltage for the field side. These contacts
come as touchproof spring contacts on the right side of the coupler/controller
and the bus module. As fitting counterparts the module has male contacts on
the left side.
Danger
The power contacts are sharp-edged. Handle the module carefully to prevent
injury.
Attention
Please take into consideration that some bus modules have no or only a few
power jumper contacts. The design of some modules does not allow them to
be physically assembled in rows, as the grooves for the male contacts are
closed at the top.

2.5.9 Wire connection
All components have CAGE CLAMP® connections.
The WAGO CAGE CLAMP® connection is appropriate for solid, stranded
and fine–stranded conductors. Each clamping unit accommodates one conductor.
Fig. 2-9: CAGE CLAMP® Connection
g0xxx08x
The operating tool is inserted into the opening above the connection. This
opens the CAGE CLAMP®. Subsequently the conductor can be inserted into
the opening. After removing the operating tool, the conductor is safely
clamped.
More than one conductor per connection is not permissible. If several conductors have to be laid at a connection, then they should be laid in off-course
wiring; e.g. together with WAGO transfer terminals.
Attention
If it is unavoidable to jointly connect 2 conductors, then a ferrule must be
used.

2.6.1 Isolation
Within the fieldbus node, there are three electrically isolated potentials.
·
Operational voltage for the fieldbus interface.
·
Electronics of the couplers / controllers and the bus modules (internal bus).
·
All bus modules have an electrical isolation between the electronics (internal bus, logic) and
the field electronics. Some analogue input modules have each channel electrically isolated,
please see catalogue.
Fig. 2-10: Isolation
g0xxx01e
Attention
The ground wire connection must be existent in each group. In order that all
protective conductor functions are maintained under all circumstances, it is
sensible to lay the connection at the beginning and end of a potential group.
(ring format, please see chapter "2.7.3"). Thus, if a bus module comes loose
from a composite during servicing, then the protective conductor connection
is still guaranteed for all connected field devices.
When using a joint power supply unit for the 24 V system supply and the
24 V field supply, the electrical isolation between the internal bus and the
field level is disregarded for the potential group.

2.6.2 System Supply
2.6.2.1 Connection
The WAGO-I/O-SYSTEM 750 requires a 24 V direct current system supply
(-15% or +20 %). The power supply is provided via the coupler / controller
and, if necessary, in addition via the internal system supply modules
(750-613). The voltage supply is reverse voltage protected.
Fig. 2-11: System Supply
g0xxx02e
The direct current supplies all internal system components, e.g. coupler/controller electronics, fieldbus interface and bus modules via the internal
bus (5 V system voltage). The 5 V system voltage is electrically connected to
the 24 V system supply.
Fig. 2-12: System Voltage
g0xxx06e
Attention
Resetting the system by switching on and off the system supply, must take
place simultaneously for all supply modules (coupler / controller and

Recommendation
A stable network supply cannot be taken for granted always and everywhere.
Therefore, regulated power supply units should be used in order to guarantee
the quality of the supply voltage.
The supply capacity of the coupler/controller or the internal system supply
module (750-613) can be taken from the technical data of the components.

the bus power supply unit. See coupler / controller
and internal system supply module (750-613)
*) cf. catalogue W3 Volume 3, manuals or Internet
Example
Coupler 750-301:
internal current consumption:350 mA at 5V
residual current for
bus modules:
1650 mA at 5V
sum I(5V) total :
2000 mA at 5V
The internal current consumption is indicated in the technical data for each bus
terminal. In order to determine the overall requirement, add together the values of all bus modules in the node.
Attention
If the sum of the internal current consumption exceeds the residual current for
bus modules, then an internal system supply module (750-613) must be
placed before the module where the permissible residual current was exceeded.
Example:
A node with a PROFIBUS Coupler 750-333 consists of 20 relay modules (750-517) and 20 digital input modules (750-405).
Current consumption:
20*105 mA = 2100 mA
10* 2 mA =
20 mA
Sum 2120 mA
The coupler can provide 1800 mA for the bus modules. Consequently,
an internal system supply module (750-613), e.g. in the middle of the
node, should be planned.
Recommendation
With the WAGO ProServe® Software smartDESIGNER, the assembly of a
fieldbus node can be configured. The configuration can be tested via the integrated plausibility check.

Power Supply
The maximum input current of the 24 V system supply amounts to 500 mA.
The exact electrical consumption (I(24 V)) can be determined with the following
formulas:
Coupler/Controller
I(5 V) total =
Sum of all current consumptions of the connected bus modules
+ internal current consumption coupler / controller
750-613
I(5 V) total =
Sum of all current consumptions of the connected bus modules
Input current I(24 V) =
5 V / 24 V * I(5 V) total / h
h = 0.87 (at nominal load)
Note
If the electrical consumption of the power supply point for the 24 V-system
supply exceeds 500 mA, then the cause may be an improperly aligned node
or a defect.
During the test, all outputs, in particular those of the relay modules, must be
active.

2.6.3 Field Supply
2.6.3.1 Connection
Sensors and actuators can be directly connected to the relevant channel of the
bus module in 1-/4 conductor connection technology. The bus module supplies
power to the sensors and actuators. The input and output drivers of some bus
modules require the field side supply voltage.
The coupler/controller provides field side power (DC 24V). Power supply
modules are available for other potentials, e.g. AC 230 V. Likewise, with the
aid of the power supply modules, various potentials can be set up. The connections are linked in pairs with a power contact.
Fig. 2-13: Field Supply (Sensor / Actuator)
g0xxx03e
The supply voltage for the field side is automatically passed on via the power
jumper contacts when assembling the bus modules .
The current load of the power contacts must not exceed 10 A on a continual
basis. The current load capacity between two connection terminals is identical
to the load capacity of the connection wires.
By setting an additional power supply module, the field supply via the power
contacts is disrupted. From there a new power supply occurs which also contains a potential alternation.
WAGO-I/O-SYSTEM 750
CC-Link
24 • The WAGO-I/O-SYSTEM 750
Power Supply
Attention
Some bus modules have no or very few power contacts (depends on the I/O
function). Due to this, the passing on of the relevant potential is disrupted. If
a field supply is required for subsequent bus modules, then a power supply
module must be used.
Note the data sheets of the bus modules.
In the case of a node setup with different potentials, e.g. the alteration from
DC 24 V to AC 230V, a spacer module should be used. The optical separation of the potentials acts as a warning to heed caution in the case of wiring
and maintenance works. Thus, the results of wiring errors can be prevented.
2.6.3.2 Fusing
Internal fusing of the field supply is possible for various field voltages via an
appropriate power supply module.

Warning
In the case of power supply modules with fuse holders, only fuses with a
maximal dissipation of 1.6 W (IEC 127) must be used.
For UL approved systems only use UL approved fuses.
In order to insert or change a fuse, or to switch off the voltage in succeeding
bus modules, the fuse holder may be pulled out. In order to do this, use a
screwdriver for example, to reach into one of the slits (one on both sides) and
pull out the holder.

2.6.6 Power Supply Unit
The WAGO-I/O-SYSTEM 750 requires a 24 V direct current system supply
with a maximum deviation of -15% or +20 %.
Recommendation
A stable network supply cannot be taken for granted always and everywhere.
Therefore, regulated power supply units should be used in order to guarantee
the quality of the supply voltage.
A buffer (200 µF per 1 A current load) should be provided for brief voltage
dips. The I/O system buffers for ca. 1 ms.
The electrical requirement for the field supply is to be determined individually
for each power supply point. Thereby all loads through the field devices and
bus modules should be considered. The field supply as well influences the bus
modules, as the inputs and outputs of some bus modules require the voltage of
the field supply.
Note
The system supply and the field supply should be isolated from the power
supplies in order to ensure bus operation in the event of short circuits on the
actuator side.

Grounding
2.7 Grounding
2.7.1 Grounding the DIN Rail
2.7.1.1 Framework Assembly
When setting up the framework, the carrier rail must be screwed together with
the electrically conducting cabinet or housing frame. The framework or the
housing must be grounded. The electronic connection is established via the
screw. Thus, the carrier rail is grounded.
Attention
Care must be taken to ensure the flawless electrical connection between the
carrier rail and the frame or housing in order to guarantee sufficient grounding.
2.7.1.2 Insulated Assembly
Insulated assembly has been achieved when there is constructively no direct
conduction connection between the cabinet frame or machine parts and the
carrier rail. Here the earth must be set up via an electrical conductor.
The connected grounding conductor should have a cross section of at least
4 mm2.
Recommendation
The optimal insulated setup is a metallic assembly plate with grounding connection with an electrical conductive link with the carrier rail.
The separate grounding of the carrier rail can be easily set up with the aid of
the WAGO ground wire terminals.

Grounding
2.7.3 Protective Earth
For the field level, the ground wire is placed onto the lower connection terminals of the power supply terminals and further reached through the lower
power contacts to the neighboring bus terminals. If the bus terminal has the
lower power contact, then the ground wire connection of the field devices can
be directly connected to the lower connection terminals of the bus terminals.
Attention
If the connection of the power contacts for the ground wire within the node is
disrupted, e.g. due to a 4-channel bus terminal, then the potential has to be resupplied.
The ring feeding of the earth potential can increase the system security. In the
event that a bus terminal is ripped out of the potential group, the earth potential is still maintained.
During the ring feeding, the ground wire is connected at the beginning and end
of the potential group.

Shielding (screening)
2.8 Shielding (screening)
2.8.1 General
The shielding of the data and signal conductors reduces the electromagnetic
influences thereby increasing the signal quality. Measurement errors, data
transmission errors and even disturbances caused by overvoltage can thus be
avoided.
Attention
Constant shielding is absolutely required in order to ensure the technical
specifications in terms of the measurement accuracy.
The data and signal conductors should be laid separately from all highvoltage cables.
The cable shield is to be laid over a large-scale surface onto the earth potential. With this, incoming disturbances can be easily diverted.
The shielding should be placed over the entrance of the cabinet or housing in
order to already repel disturbances at the entrance.
2.8.2 Bus Conductors
The shielding of the bus conductor is described in the relevant assembly
guideline of the bus system.
2.8.3 Signal Conductors
The bus terminals for analogue signals as well as some interface bus terminals
possess connection terminals for the shield.
Note
Improved shielding can be achieved if the shield is previously placed over a
large-scale surface. For this, we recommend the use of the WAGO shield
connecting system for example.
This is particularly recommendable for systems with large-scale expansions
where it cannot be ruled out that differential currents are flowing or high
pulse currents, i. e. activated by atmospheric discharge, may appear.

Fieldbus coupler 750-310
3.1.1 Description
The fieldbus coupler 750-310 mappes the peripheral data of all connected I/O
modules to the CC-Link Bus.
The bus coupler determines the physical structure of the node and automatically creates a local process image from this with all inputs and outputs. This
could involve a mixed arrangement of analog (word by word data exchange)
and digital (byte by byte data exchange) modules.
The data of the analog modules are mapped into the process image according
to the order of their position downstream of the bus coupler. The bits of the
digital modules are compiled to form bytes and also mapped into the process
image attached to the data of the analog modules. Should the number of digital
I/Os exceed 8 bits, the coupler automatically starts another byte.
The process image is subdivided into an input and output data area. The process data can be read in via the CC-Link bus and further processed in a control
system. The process output data is sent via the CC-Link bus.

After switching on the supply voltage, the coupler performs a self test of all
functions of its devices, the I/O module and the fieldbus interface. Following
this the I/O modules and the present configuration is determined, whereby an

In the event of a fault the coupler changes to the "Stop" condition. The "I/O"
LED flashes red. After clearing the fault and cycling power, the coupler
changes to the "Waiting for initial data" status and the "I/O" LED starts
blinking up green. After receiving this data from the master station, the coupler changes to the "Fieldbus start" status and the "I/O" LED lights up green.

3.1.4 Process Image
3.1.4.1 Local Process Image
After powering up, the coupler recognizes all I/O modules plugged into the
node which supply or wait for data (data width/bit width > 0). In the nodes
analog and digital I/O modules can be mixed.
The coupler produces an internal process image from the data width and the
type of I/O module as well as the position of the I/O modules in the node. It is
divided into an input and an output data area.
The data of the digital I/O modules are bit orientated, i.e. the data exchange is
made bit for bit. The analog I/O modules are all byte orientated I/O modules,
i.e. modules where the data exchange is made byte for byte. These I/O modules include for example the counter modules, I/O modules for angle and path
measurement as well as the communication modules.
Note
For the number of input and output bits or bytes of the individual I/O modules
please refer to the corresponding I/O module description.
The data of the I/O modules are separated for the local input and output process image in the sequence of their position after the coupler in the individual
process image.
In the respective I/O area, first of all analog modules are mapped, then all
digital modules, even if the order of the connected analog and digital modules
does not comply with this order. The digital channels are grouped, each of
these groups having a data width of 1 byte. Should the number of digital I/Os
exceed 8 bits, the coupler automatically starts another byte.
Note
A process image restructuring may result if a node is changed or extended. In
this case the process data addresses also change in comparison with earlier
ones. In the event of adding a module, take the process data of all previous
modules into account.

3.1.4.3 Data Exchange
After mapping the I/O-data of the bus modules to the local process image the
coupler cyclically transfers the digital input data from the process image to the
Remote I/O area and the analog input data to the Remote Register area. In the
same way the digital output data from the Remote I/O area and the analog output data from the Remote Register area to the are transferred to the process
image.

3.1.5.2 Node Status
The coupler starts after switching on the supply voltage. The "I/O" LED
flashes red. Following an error free start up the "I/O" LED starts blinking
green. The blinking sequence shows the number of occupied stations. The
coupler is now waiting for its intial data sent by the master station. After receiving this data the “I/O” LED changes to steady green light.
In the case of a fault the "I/O" LED continues blinking red. The fault is cyclically displayed with the blink code.

Foreword
6 Application in Explosive Environments
6.1 Foreword
Today’s development shows that many chemical and petrochemical companies have production plants, production, and process automation machines in
operation which use gas-air, vapor-air and dust-air mixtures which can be explosive. For this reason, the electrical components used in such plants and
systems must not pose a risk of explosion resulting in injury to persons or
damage to property. This is backed by law, directives or regulations on a national and international scale. WAGO-I/O-SYSTEM 750 (electrical components) is designed for use in zone 2 explosive environments. The following
basic explosion protection related terms have been defined.
6.2 Protective Measures
Primarily, explosion protection describes how to prevent the formation of an
explosive atmosphere. For instance by avoiding the use of combustible liquids, reducing the concentration levels, ventilation measures, to name but a
few. But there are a large number of applications, which do not allow the implementation of primary protection measures. In such cases, the secondary explosion protection comes into play. Following is a detailed description of such
secondary measures.
6.3 Classification Meeting CENELEC and IEC
The specifications outlined here are valid for use in Europe and are based on
the following standards: EN50... of CENELEC (European Committee for
Electrotechnical Standardization). On an international scale, these are reflected
by the IEC 60079-... standards of the IEC (International Electrotechnical
Commission).
6.3.1 Divisions
Explosive environments are areas in which the atmosphere can potentially become explosive. The term explosive means a special mixture of ignitable substances existing in the form of air-borne gases, fumes, mist or dust under atmospheric conditions which, when heated beyond a tolerable temperature or
subjected to an electric arc or sparks, can produce explosions. Explosive zones
have been created to describe the concentrations level of an explosive atmosphere. This division, based on the probability of an explosion occurring, is of
great importance both for technical safety and feasibility reasons. Knowing
that the demands placed on electrical components permanently employed in an
explosive environment have to be much more stringent than those placed on
electrical components that are only rarely and, if at all, for short periods, subject to a dangerous explosive environment.
WAGO-I/O-SYSTEM 750
CC-Link
70 • Application in Explosive Environments
Classification Meeting CENELEC and IEC
Explosive Areas Resulting from Gases, Fumes or Mist:
· Zone 0 areas are subject to an explosive atmosphere
(> 1000 h /year) continuously or for extended periods.
· Zone 1 areas can expect the occasional occurrence of an explosive atmosphere (> 10 h £ 1000 h /year).
· Zone 2 areas can expect the rare or short-term occurrence of an explosive
atmosphere (> 0 h £ 10 h /year).
Explosive Areas Subject to Air-borne Dust:
· Zone 20 areas are subject to an explosive atmosphere
(> 1000 h /year) continuously or for extended periods.
· Zone 21 areas can expect the occasional occurrence of an explosive atmosphere (> 10 h £ 1000 h /year).
· Zone 22 areas can expect the rare or short-term occurrence of an explosive
atmosphere (> 0 h £ 10 h /year).
6.3.2 Explosion Protection Group
In addition, the electrical components for explosive areas are subdivided into
two groups:
Group I:
Group I includes electrical components for use in fire-damp
endangered mine structures.
Group II:
Group II includes electrical components for use in all other
explosive environments. This group is further subdivided by
pertinent combustible gases in the environment.
Subdivision IIA, IIB and IIC takes into account that different materials/substances/gases have various ignition energy
characteristic values. For this reason the three sub-groups
are assigned representative types of gases:
·
·
·
IIA – Propane

The maximum surface temperature for electrical components of explosion
protection group I is 150 °C (danger due to coal dust deposits) or 450 °C (if
there is no danger of coal dust deposit).
In line with the maximum surface temperature for all ignition protection types,
the electrical components are subdivided into temperature classes, as far as
electrical components of explosion protection group II are concerned. Here the
temperatures refer to a surrounding temperature of 40 °C for operation and
testing of the electrical components. The lowest ignition temperature of the
existing explosive atmosphere must be higher than the maximum surface temperature.

Ignition protection “n" describes exclusively the use of explosion protected
electrical components in zone 2. This zone encompasses areas where explosive atmospheres can only be expected to occur rarely or short-term. It represents the transition between the area of zone 1, which requires an explosion
protection and safe area in which for instance welding is allowed at any time.
Regulations covering these electrical components are being prepared on a
world-wide scale. The standard EN 50 021 allows electrical component manufacturers to obtain certificates from the corresponding authorities for instance
KEMA in the Netherlands or the PTB in Germany, certifying that the tested
components meet the above mentioned standards draft.
Type “n” ignition protection additionally requires electrical components to be
marked with the following extended identification:
· A – non spark generating (function modules without relay /without switches)
· AC – spark generating, contacts protected by seals (function modules with
relays / without switches)
· L – limited energy (function modules with switch)
