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, EU-
type examination certificates, certificates, and control drawings if
applicable supplement this document. You can find this information under
www.pepperl-fuchs.com.
For specific device information such as the year of construction,
scan the QR code on the device. As an alternative, enter the serial number
in the serial number search at 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 transfer of signals such as 20 mA and
10 V standard signals. The device has intrinsically safe circuits that are
used for operating intrinsically safe field devices in hazardous areas.
Use the device only within the specified ambient and operating conditions.
The device is designed for mounting on a 35 mm DIN mounting rail
according to EN 60715.
The device is an associated apparatus according to IEC/EN 60079-11.
The device is an electrical apparatus for hazardous areas of Zone 2.
The device may be installed in the non-hazardous area.

5. Improper Use

Protection of the personnel and the plant is not ensured if the device
is not used according to its intended use.

6. Mounting and Installation

Do not mount a damaged or polluted device.
Mount the device in a way that the device is protected against mechanical
hazard. Mount the device in a surrounding enclosure for example.
Do not mount the device in the dust hazardous area.
The device fulfills a degree of protection IP20 according to IEC/EN 60529.
DOCT-4849B / 2023-04
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.
The device must be installed and operated only in an environment of
overvoltage category II (or better) according to IEC/EN 60664-1.
Observe the installation instructions according to IEC/EN 60079-14.

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.
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.
If no L and C values are specified for the simultaneous appearance of
o o
lumped inductances and capacitances, the following rule applies.
The specified value for L
l
conditions applies:
The circuit has distributed inductances and capacitances only, e. g.,
l
in cables and connection lines.
The total value of L
l
specified L value.
o
The total value of C
l
specified C value.
o
A maximum of 50 % of the specified value for L
l
following condition applies:
The total value of L (excluding cable) of the circuit is ≥ 1 % of the
i
specified L value.
o
The total value of C (excluding cable) of the circuit is ≥ 1 % of the
i
specified C value.
o
The reduced capacitance for gas groups I, IIA, and IIB must not exceed
l
the value of 1 µF (including cable). The reduced capacitance for
gas group IIC must not exceed the value of 600 nF (including cable).
If more channels of one device are connected in parallel, ensure the
parallel connection is made directly at the terminals of the device. When
verifying the intrinsic safety, observe the maximum values for the parallel
connection.
Observe the grounding requirements for type of protection Ex i according
to IEC/EN 60079‑14.
Ensure that external ground connections exist, are in good condition, and
are not damaged or corroded.
Requirements For Equipment Protection Level Gc
The device must be installed and operated only in surrounding enclosures
that
