2. Validity
Specific processes and instructions in this instruction manual require
special provisions to guarantee the safety of the operating personnel.
3. 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.
4. Reference to Further Documentation
Observe laws, standards, and directives applicable to the intended use
and the operating location. Observe Directive 1999/92/EC in relation to
hazardous areas.
The corresponding datasheets, manuals, declarations of conformity, EU-
type examination certificates, certificates, and control drawings if
applicable (see datasheet) are an integral part of 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.
Due to constant revisions, documentation is subject to permanent change.
Please refer only to the most up-to-date version, which can be found under
www.pepperl-fuchs.com.
5. 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 VisuNet FLX Systems are designed for Zone 2/22 and non-Ex
applications. The different mounting and configuring options lead to the
highest application flexibility. Due to a fully modular design, the new
platform, which is geared to the needs of the (petro-) chemical and
pharmaceutical industries, the HMIs can be configured to fit exactly and
enables simple and fast adjustments in the field.
Use the device only within the specified ambient temperature range.
Use the device only within the specified ambient and operating conditions.
Take the intended use of the connected devices from the corresponding
documentation.
Take the intended use of the installed devices from the corresponding
documentation.
The device is an electrical apparatus for hazardous areas.
The device is not suitable for separating hazardous areas.
Devices for which specific conditions of use apply have the X marking at
the end of the certificate number.
Only use the device stationary.
6. 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 to separate intrinsically safe circuits from non-
intrinsically safe circuits.
The device is not suitable for separating hazardous areas.
7. Specific Conditions of Use
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.
Use the device only within the specified ambient and operating conditions.
Install the device in locations with a low risk of mechanical hazard
according to IEC/EN 60079-0 only.
Avoid mechanical impacts to the device (e. g. from heavy or sharp-
edged objects).
Avoid inadmissibly high electrostatic charge on the device.
Mount the device in a location with low electrostatic charge.
Secure the connections of the non-intrinsically safe circuits
against loosening by suitable means.
Do not use interfaces that are not intended for the use in the explosion-
hazardous area.
Do not use operating elements that are not intended for the use
in the explosion-hazardous area.
Some interfaces of the device must be closed during operation
in the explosion-hazardous area. Ensure that these interfaces are closed.
For DC Supply
The device must be installed and operated only in an environment of
overvoltage category II (or better) according to IEC/EN 60664-1.
Only connect supplies that provide protection against electric shock (e. g.
SELV or PELV).
For AC Supply
The device must be installed and operated only in an environment of
overvoltage category III (or better) according to IEC/EN 60664-1.
8. Mounting and Installation
Prior to mounting, installation, and commissioning of the device you
should make yourself familiar with the device and carefully read the
instruction manual.
Do not stay below the open device. In order to avoid personal injuries or
property damage, make appropriate provisions for the mounting and
maintenance procedures.
Use mounting materials which are suitable to secure the device safely.
Use mounting materials that fit the nature of the mounting surface.
Only use accessories specified by the manufacturer.
