1.4.1 Marking
The modules are product-specifically marked with:
1.5 Non-Intended Use
The Ethernet Isolators are not intended to be used for series connections of more than two
Ethernet Isolators.
1.6 Installation and Commissioning
1.6.1 Requirements for installation within Zone 2
The device must be mounted for installation in the hazardous area in category 3G / Zone 2 in a
housing which corresponds at least to protection class IP 54 per EN 60529 and which is
suitable for this type of installation.
The connection and disconnection of non-power-limited circuits carrying current is permitted
only during installation or maintenance, or for purposes of repair.
Devices being operated in connection with hazardous areas may not be changed or
manipulated. If there is a defect, the product must always be replaced with an original part.
If devices have been operated in general electrical systems, they must not subsequently be
operated in electrical systems related to explosive areas.
1.6.2 Installation in connection with intrinsically safe power circuits
The EC-type-examination certificate should be observed as first concern. It is especially
important to observe the "special conditions for safe use" as far as contained in the certificate.
The installation of the intrinsically safe circuits has to be conducted in accordance with the
relevant installation regulations particularly EN 60079-14 / IEC 60079-14.
Connect only devices that are approved by EC-type-examination certificate of the Ethernet
Isolator for this kind of use, to the I.S. port of the Ethernet Isolator.
If devices have been operated in general electrical systems, they must not subsequently be
operated in electrical systems related to explosive areas.

Safety
1.6.3 Intrinsically Safe Wiring and Cable Parameter
Only Ethernet cables which meet the requirements of the EC-type-examination certificate must
be connected to the I.S. port of the Ethernet Isolator.
Special care must be taken about the inductance / resistance-ratio (H/:) of the used Ethernet
cable, because this value is an indicator for the stored energy within the cable (see chapter
2.4).
The length of the I.S. cable between the two Ethernet Isolators may not ecxeed 100m.
The shield contact of the intrinsically safe port is connected to the shield contact of the non-
intrinsically safe port and the power supply connection within the Ethernet Isolator.
1.6.4 Special Requirements at Low Ambient Temperatures
At an ambient temperature of -40°C to -25°C the Ethernet interface contacts (RJ45) of the
device must not be plugged or un-plugged or mechanically stressed in any other way.
1.7 Transport, Storage and Service
In case of defect, the device must be removed and replaced with a new one.
Store all devices in a clean and dry environment.
1.8 Disposal
Disposal of devices and their packaging material must be performed in compliance with the
applicable laws and guidelines of the corresponding country.
The devices do not contain batteries which need to be disposed of separately from the
products.

2 Product Specifications
2.1 Function
The Ethernet Isolator may be installed within the safe area and the Zone 2 hazardous area. As
an associated apparatus it is certified to lead intrinsically safe instrumentation into Zone 0 and
Zone 1 hazardous areas. It is a one-to-one data connector with automatic speed detection.
Data is passed through without buffering.
The Ethernet Isolator can be used for any Ethernet-based application. This includes current
and future PROFINET and FF HSE installations. This intrinsically safe solution is well suited
for:
• mobile machinery and equipment in harsh environments
• assemblies that are often removed, replaced or reworked
• where cable breakage is a risk
The intrinsically safe energy limitation eliminates any need for protected installation.
Intrinsically safe Ethernet can be connected and disconnected during normal plant operation
without requiring a hot work permit.
The galvanic isolation eliminates the need for equipotential bonding between the safe area and
the hazardous area. Significant cost savings are realized through reduced installation material
and effort.
The internal design of the Ethernet Isolator includes a galvanically isolating fibre optic bridge
and a voltage and current limiting circuit. Additionally it is following the stringent requirements
for energy-efficient design and low heat dissipation leading to reduced cooling requirements
and if necessary highest packing density in the installation cabinet or equipment.

2.2 Typical Applications
The figure below (view Figure 2.1 on page 10) shows the typical usage of Ethernet Isolators
within an Ethernet network. Using standard Ethernet cable (for cable parameters see chapter
2.4) and hardware, an up to 100 m long intrinsically safe connection can be established to
connect the hazardous area and the network in the safe area. It is also a fast and easy way to
bridge the Ethernet network through a Zone 0 or Zone 1 hazardous area. One Ethernet Isolator
is required at each end of the intrinsically safe line.
The Ethernet Isolator requires a 24 VDC power supply.

3 Installation and Commissioning
3.1 Mounting
Read the chapter on Safety and, in particular, the section on Installation and Commissioning
(see chapter 1.6) before installing the device.
DIN-Rail Mounting of the Ethernet Isolator
Snap the device onto the DIN rail as follows:
3.2 Power Supply and Ethernet Wiring
Additional information about auto crossover
The Ethernet Isolator does not support auto crossover functionality. Therefore connection
problems may happen if the Ethernet Isolator is installed between two devices with activated
auto crossover function. In general the deactivation of the auto crossover function at one
device solves the problem. In certain cases you have to switch off auto crossover at both sides.
To prevent those connection problems Pepperl+Fuchs recommends a fixed setup of the
transfer polarity.
Additonal information about signal attenuation
Because of derating effects at raising ambient temperatures the max. posible Ethernet cable
length may be reduced by 0.3 –0.4 m per °C depending on the cable quality and signal
attenuation (refer to the specifications of the cable manufacturer).

Ethernet Wiring
1. Plug in the standard, non-specific Ethernet cable into the non-I.S.-ports of the device.
2. Now interconnect the two Ethernet Isolators by plugging in an Ethernet cable into both I.S.-
ports of the devices.
3.2.1 Ethernet Cabel Overview for Interconnection
The cross-table below gives a general idea which Ethernet cable has to be used for
interconnection of two Ethernet Isolators or an Ethernet Isolator to another device.
General Information about Standard Ethernet Patch and Crossover Cables
The TIA/EIA-568-B Ethernet connector specification defines two types of pin assignment for an
Ethernet cable. The standard Ethernet patch cable is a straight through connection of where
both RJ45 ends wired the same. The Ethernet crossover cable has the RX and TX pairs
switched between the end terminals.

ETHERNET ISOLATOR
Installation and Commissioning
In order to guarantee the communication across the cable the transmit signal of terminal device
A has to connect to the receive port of terminal device B and vice versa. The signal has to be
crossed at least once in a connection. A switched hub (switch) typically performs signal
crossing internally and this is why a standard Ethernet patch cable is to be used to connect to
another non-crossing device as well if a device supports an auto-crossover detection function.
The crossover cable on the other hand is used when connecting two devices that do either both
not cross or do both cross the signals. In this case the crossover must be done externally.
3.3 Demounting
Demounting from the DIN-Rail
Use a screw driver to loose the fixing trap and remove the module from the DIN rail.

Electromagnetic Compatibility Verification in Accordance with EC Council Legislation
5 Electromagnetic Compatibility Verification in Accordance
with EC Council Legislation Directive 89/336/EEC
Compatibility in accordance with EN 61326
The electromagnetic compatibility –EMC –requirements applicable for electrical equipment for
measurement, control and laboratory use in general are anchored in the European Standard
EN 61326. Three different categories of device performances are distinguished:
A category A device –operates as intended during the test. This device can withstand the
immunity tests without any noticeable performance degradations within the specification limits
of the manufacturer.
A category Bdevice –operates as intended after the test. The device shows temporary
degradation or loss of function of performance during the test but self-recovers from that state
when the exposures are ceased.
A category Cdevice –has loss of function, may need manual restoration. During the test a
temporary loss of function is allowed as long as an operator can restore the device back to
operation.

Compatibility in accordance with NAMUR NE 21
Compared to EN 61326, the NE 21 of the international user association of automation
technology for process industries NAMUR recommends passing category level A for ESD and
Burst.
In general category A conformity has a lasting effect on increasing the application’s availability
just in case and is an everlasting argument for the product’s quality. Conformity to a lower
category will become a limiting factor on the overall performance of the whole installation.
Especially for wired communications technology this leads to:
• increased number of immediate transmission retries
• retries at upper protocol level
• prolonged overall data transfer time
• dead times in control cycles
• control loops oscillating due to missing telegrams
In comparison category A conformity gives you:
• stable and less distorted signal quality
• least impact on communication signal
• no unnecessary telegram re-transmissions
• constant throughput and guaranteed deterministic timings
