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.

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 transformer isolated barrier
transfers digital signals from the
hazardous area. Sensors per
DIN EN 60947-5-6 (NAMUR) and
mechanical contacts may be used as
alarms. Control circuits are monitored
for lead breakage (LB) and short circuit
(SC). The external faults are indicated
according to NAMUR NE44 by a red
flashing LED. For type KFD2-SR2-
Ex2.W, an LB/SC collective error
message is in addition transferred
through the Power Rail to the power
feed module. The intrinsically safe
inputs per DIN EN 50020 are safely
isolated from the output and the power
supply. Relay outputs are galvanically
separated from the mains power in
accordance with IEC 61140. Relay
outputs are galvanically separated from
each other in accordance with
IEC 61140.
