2. Target Group, Personnel

Responsibility for planning, assembly, commissioning, operation,
maintenance, and dismounting lies with the plant operator.

The personnel must be appropriately trained and qualified in order to carry
out mounting, installation, commissioning, operation, maintenance, and
dismounting of the device. The trained and qualified personnel must have
read and understood the instruction manual.

Prior to using the product make yourself familiar with it. Read the
instruction manual carefully.

3. Reference to Further Documentation

Observe laws, standards, and directives applicable to the intended use
and the operating location.

For mining applications, observe laws, standards, and directives
applicable to the operating location.

The corresponding datasheets, manuals, declarations of conformity, EU­type examination certificates, certificates, and control drawings if
applicable supplement this document. You can find this information under
www.pepperl-fuchs.com.

If you use the device in safety-related applications, observe the
requirements for functional safety. You can find these requirements in the
functional safety documentation under www.pepperl-fuchs.com.

4. Intended Use

The device is only approved for appropriate and intended use. Ignoring
these instructions will void any warranty and absolve the manufacturer
from any liability.

The device is used in control and instrumentation technology
(C&I technology) for the galvanic isolation of signals such as 20 mA and
10 V standard signals or alternatively for adapting or standardizing signals.
The device has intrinsically safe circuits that are used for operating
intrinsically safe field devices in hazardous areas.

The device transfers digital signals from NAMUR sensors or dry contacts
from the hazardous area to the non-hazardous area.

Use the device only within the specified ambient and operating conditions.
Only use the device stationary.
The device is an associated apparatus according to IEC/EN 60079-11.
The device may be installed in the non-hazardous area.
The device is an electrical apparatus for hazardous areas of Zone 2.
If you use the device in safety-related applications, observe the

information for safety function and safe state.

6. Mounting and Installation

Do not mount a damaged or polluted device.
The device is designed for mounting on a 35 mm DIN mounting rail

according to EN 60715.
Mount the device in a way that the device is protected against mechanical

hazard. Mount the device in a surrounding enclosure for example.
The device fulfills a degree of protection IP20 according to IEC/EN 60529.
The device must be installed and operated only in a controlled

environment that ensures a pollution degree 2 (or better) according to
IEC/EN 60664-1.

If used in areas with higher pollution degree, the device needs to be
protected accordingly.

Do not mount the device in the dust hazardous area.
The device must be installed and operated only in an environment of

overvoltage category II (or better) according to IEC/EN 60664-1.
Supply the device with a power supply that meets the requirements for

safety extra-low voltage (SELV) or protective extra-low voltage (PELV).
If you are using the Power Rail, supply the Power Rail only via the

corresponding power feed modules or power supplies. Do not supply the
Power Rail via isolators.

Observe the installation instructions according to IEC/EN 60079-14.
If you install the device in safety-related applications, observe the

requirements for functional safety.

Requirements for Cables and Connection Lines

Observe the permissible core cross section of the conductor.
When using stranded conductors, crimp wire end ferrules on the

conductor ends.
Use only one conductor per terminal.
When installing the conductors the insulation must reach up to the

terminal.
Use conductors with a rated temperature suitable for the application.
If you use the device in an ambient temperature above 60 °C, use

conductors rated for a temperature of at least 80 °C.
Observe the tightening torque of the terminal screws.

Requirements for Usage as Associated Apparatus

If circuits with type of protection Ex i are operated with non-intrinsically
safe circuits, they must no longer be used as circuits with type of
protection Ex i.

Keep the separation distances between all non-intrinsically safe circuits
and intrinsically safe circuits according to IEC/EN 60079-14.

Observe the compliance of the separation distances between two
adjacent intrinsically safe circuits according to IEC/EN 60079-14.

Observe the respective peak values of the field device and the associated
apparatus with regard to explosion protection when connecting intrinsically
safe field devices with intrinsically safe circuits of associated apparatus
(verification of intrinsic safety). Also observe IEC/EN 60079-14 and
IEC/EN 60079-25.

Requirements for Equipment Protection Level Gc

The device must be installed and operated only in surrounding enclosures
that

l

comply with the requirements for surrounding enclosures according to
IEC/EN 60079-0,

l

are rated with the degree of protection IP54 according to
IEC/EN 60529.

Ensure that the surrounding enclosure can only be opened with a tool.
Connection or disconnection of energized non-intrinsically safe circuits is

only permitted in the absence of a potentially explosive atmosphere.

7. Operation, Maintenance, Repair

If you operate the device in safety-related applications, observe the
requirements for functional safety. For the proof test, plan appropriate
intervals for the operation in low demand mode.

Do not use a damaged or polluted device.
Do not repair, modify, or manipulate the device.
If there is a defect, always replace the device with an original device.

Connection or disconnection of energized non-intrinsically safe circuits is
only permitted in the absence of a potentially explosive atmosphere.

Only use operating elements in the absence of a potentially explosive
atmosphere.
