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.
Reference to Further Documentation
Observe laws, standards, and directives applicable to the intended use and 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.
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.
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.
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.
Only use the device stationary.
The device is an associated apparatus according to IEC/EN 60079-11.
The device is an electrical apparatus for hazardous areas of Zone 2.
Improper Use
Protection of the personnel and the plant is not ensured if the device is not
used according to its intended use.
The device is not suitable for isolating signals in power installations unless
this is noted separately in the corresponding datasheet.
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.
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.
The device may be installed in a corrosive atmosphere according to
ISAS71.04-1985, severity level G3.
Only connect supplies that provide protection against electric shock to power
feed modules (e. g. SELV or PELV).
Observe the installation instructions according to IEC/EN 60079-14.
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.
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.
Intrinsically safe circuits of associated apparatus can be led into hazardous
areas. Observe the compliance of the separation distances to all non-
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 maximum values of the device, when connecting the device to
intrinsically safe apparatus.
When connecting intrinsically safe devices with intrinsically safe circuits of
associated apparatus, observe the maximum peak values with regard to explosion
protection (verification of intrinsic safety). Observe the standards IEC/EN
60079-14 or IEC/EN 60079-25.
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.
Requirements for Equipment Protection Level Gc
The device must be installed and operated only in surrounding enclosures that
- comply with the requirements for surrounding enclosures according to IEC/EN 60079-0,
- are rated with the degree of protection IP54 according to IEC/EN 60529.
Connection or disconnection of energized non-intrinsically safe circuits is
only permitted in the absence of a potentially explosive atmosphere.
Provide a transient protection. Ensure that the peak value of the transient
protection does not exceed 140 % of the rated voltage.
Only use the programming socket in the absence of a potentially explosive
atmosphere.
Operation, Maintenance, Repair
Do not repair, modify, or manipulate the device.
If there is a defect, always replace the device with an original device.
Requirements for Equipment Protection Level Gc
Connection or disconnection of energized non-intrinsically safe circuits is
only permitted in the absence of a potentially explosive atmosphere.
Only use the programming socket in the absence of a potentially explosive
atmosphere.
Delivery, Transport, Disposal
Check the packaging and contents for damage.
Check if you have received every item and if the items received are the ones
you ordered.
Always store and transport the device in the original packaging.
Store the device in a clean and dry environment. The permitted ambient
conditions must be considered, see datasheet.
The device, built-in components, packaging, and any batteries contained within
must be disposed in compliance with the applicable laws and guidelines of the
respective country.
