Safety
General
Responsibility for planning, assembly, commissioning, operation, maintenance, and
dismounting lies with the plant operator.
Installation and commissioning of all devices may only be performed by trained and qualified
personnel.
Protection of operating personnel and the system is not ensured if the product is not used in
accordance with its intended purpose.
Laws and regulations applicable to the usage or planned purpose of usage must be observed.
Devices are only approved for proper usage in accordance with intended purpose. Improper
handling will result in voiding of any warrantee ormanufacturer's responsibility.
The Declaration of Conformity, Certificate of Compliance, Statement of Conformity, EC-type-
examination certificate and data sheets are an integral part of this document.
The data sheet contains the electrical data of the Declaration of Conformity, the Certificate of
Compliance and the EC-type-examination certificate.
The documents mentioned are available from http://www.pepperl-fuchs.com or contact your
local Pepperl+Fuchs representative.
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 environment. The permitted storage temperature
(see datasheet) must be considered.
Installation and Commissioning EXTA2
Prior to mounting, installation, and commissioning of the device you should make yourself
familiar withthe device and carefully read the instruction manual.
Installation in the presence of intrinsically safe circuits
The intrinsically safe circuits of the devices areallowed to be introduced into hazardous areas.
In this case, they must be safely isolated from all non-intrinsically safe circuits.
The intrinsically safe circuits must be installed in accordance with the applicable installation
regulations.
If intrinsically safe field devices are interconnected with the intrinsically safe circuits in
associated devices, the respective maximum values of these field devices and the associated
devices must be complied with in the interests of explosion protection (verification of intrinsic
safety). Account must be taken of EN 60079-14 / IEC 60079-14. Compliance with the "National
Foreword" of DIN EN 60079-14 / VDE 06165 Part 1 must be additionally ensured if the devices
are used in the Federal Republic of Germany.
The identification plate must not be removed.
The device must be free of voltage during installation and maintenance. The keyboard/mouse
must only be connected to the supply voltage after complete mounting and connection.
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 60079-
32-1.

1.5 Repair and Maintenance
The device must not be repaired, changed, or manipulated. In case of failure, always replace
the device with an original device.
1.5.1 Maintenance
Standards, directives, or statutory requirements stipulating regular system tests may exist in
connection with keyboards and mouse devices used as part of a system.
The keyboard functionality should be tested at least twice per year, or more often under heavy-
duty conditions.
Do not use caustic fluids to clean the keyboard.
A dirty keyboard could cause a malfunction or ultimately stop working.
1.6 Disposal
Disposal of devices and their packaging material must be performed in compliance with the
applicable laws and guidelines of the corresponding country.
The devices do not contain any batteries that need to be disposed of separately from the
products.
1.7 Intended Use of the EXTA2 Keyboard
EXTA2 is a PC keyboard with an optional control element for mouse functions (touchpad,
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.

Equipotential Bonding
1. The shielding of the keyboard cable must be connected in the cable gland of the PC/display
(VisuNet) (refer to VisuNet manual). Before doing this, open the cable clip (1) and remove
the cable protective tube (2).
■(1) cable clip
■(2) cable protective tube
2. Install the keyboard in a metal housing that is connected to PE.
Danger!
Explosion Hazard
Risk of fatal injury and severe property damage.
The housing must always be connected to the PE. There are 2 possibilities:
Connection via cable shielding of the connecting cable.
Built into a metal housing that is connected to the PE.

3.2 Installation Instructions for Hazardous-Location EMC Cable Glands
Power supply cables for the Ex e Ethernet and the RS-485 or TTY Ex e data interface, the Ex i
keyboard, and the Ex i scanner must be shielded to ensure sufficient immunity to interference
(EMC). Connect the cable shielding to the VisuNet RM/PC according to the following
installation instructions:
Step 1
■Isolate the cable.
■Expose the braid.
■Remove the braid and insulation little by
little.
■With thin cables, the braid can be folded
back over the insulation sheath.
■Insert the cable into the gland until the
braid reaches the contact point.
■Tighten the cable gland.
Step 2
■Guide the cable through the lock nut.
■Guide the cable into the terminal insert.
■Fold the braid over the insert.
■The braid must overlap the O-ring by about
2 mm
Step 3
■Fit the terminal insert into the intermediate
gland.
■Assemble the cable gland.

To simplifiy keyboard mounting, you can remove the cables from the keyboard PCB. After you
have mounted the keyboard, reattach all cables properly—including the PA cable. Tighten
