Safety
1 Safety
1.1 General
Responsibility for planning, assembly, commissioning, operation, maintenance, and dismounting lies with the plant operator.
Installation und Inbetriebnahme aller Geräte dürfen nur von Fachpersonal durchgeführt
werden.
Protection of operating personnel and the system is not ensured if the product is not used in
accordance with its intended use.
Observe the applicable laws and regulations regarding the intended use of the device. The
devices are only approved for proper use for the intended purpose. Improper use will void any
warranty and liability claims.
The corresponding datasheets, declarations of conformity, and/or EC-type examination certificates form an integral part of this document. The data sheet contains the electronic data of the
EC-type-examination certificate.
These documents can be found at www.pepperl-fuchs.com or contact your local Pepperl+Fuchs representative.
1.2 Delivery, Transport, and Storage
Check the packaging and contents for damage.
Check if you have received every item and if the items received are the ones you ordered.
Keep the original packaging. Always store and transport the device in the original packaging.
Always store the device in a clean and dry location. Observe the permissible storage temperature (see datasheet).
1.3 Installation and Commissioning
Prior to mounting, installation, and commissioning of the device you should make yourself
familiar with the device and carefully read the instruction manual.
Installing alongside Intrinsically Safe Circuits
The intrinsically safe circuits of the devices may be installed in hazardous areas. In such cases,
they must be securely isolated from all non-intrinsically safe circuits.
The intrinsically safe current circuits must be installed in accordance with the applicable installation regulations.
If intrinsically safe field devices are connected to the intrinsically safe circuits in associated
devices, the respective maximum values of these field devices and the associated devices
must be observed to ensure explosion protection (verification of intrinsic safety). EN 6007914/IEC 60079-14 must be taken into account. The "National Foreword" (Nationale Vorwort) of
DIN EN 60079-14/VDE 06165 Part 1 must be observed if the device is used in Germany.
The nameplate must not be removed.
The device must be de–energized during installation and servicing. The keyboard/mouse must
not be connected to the supply voltage until the mounting and connection processes have
been fully completed.
Individually accessible non-grounded metal parts can become electrostatically charged. The
determined capacitance exceeds the required value according to IEC/EN 60079-0. The determined capacitance is specified in the technical data.
Information on electrostatic hazards can be found in the technical specification IEC/TS 6007932-1.

1.5 Repair and Servicing
The device must not be repaired, changed, or manipulated. In case of failure, always replace
the device with an original device.
1.5.1 Servicing
If keyboards and mouse devices are used as parts of a system, standards, guidelines, or legal
requirements may exist that stipulate regular system tests.
Keyboard functionality should be checked at least twice a year or more frequently if the keyboard is subject to difficult conditions.
Do not clean the keyboard with corrosive liquids.
Any contamination can cause the keyboard to malfunction or completely fail.

1.6 Disposal
The devices and the packaging material must be disposed of in accordance with the current
applicable statutes and regulations in the respective country.
The devices do not contain any batteries that require separate disposal.
1.7 Intended Use of the EXTA2 Keyboard
EXTA2 is a PC keyboard with an optional control element for mouse functions (touchpad,
mechanical trackball, joystick). The keyboard has USB interfaces for intended use in Zone 1
and Zone 21 hazardous areas according to ATEX Directive 2014/34/EU and IECEx. The USB
interfaces of the keyboard and the control element for mouse functions are separated, intrinsically safe circuits. Both intrinsically safe circuits are led out either in one or two separate connection cables. The conncection cable corresponds to type "B" according IEC 60079-14
section 12.2.2.8. The cable has to be secured and effectively protected from damage. The
EXTA2 keyboard cannot be installed in locations where corrosive media may be used.
To avoid discharge processes, the keyboard may only be installed in areas where high electrostatic buildup due to dust is unlikely. To avoid electrostatic charging, the keyboard cannot be
covered or glued with foils.
The keyboard cannot be exposed to direct sunlight, unless it is equipped with the UV-resistant
foil option.
When connecting the EXTA2 keyboard to a VisuNet RM/PC, keep in mind that the USB connection is not hot swappable. Connect the keyboard cable when there is no voltage applied.
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.
