EXTA4-* Keyboard
Product Description
3 Product Description
Overview
EXTA4-* is a PC keyboard with an optional control element for mouse functions (touchpad,
opticall trackball, joystick). The keyboard is a USB device for intended use in Zone 1/21 and
Zone 2/22 hazardous areas according to ATEX Directive 2014/34/EU and ECEx.
The USB interfaces of the keyboard and the control element for mouse functions are sepa-
rated, 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 to EC
60079-14 section 12.2.2.8. The cable has to be secured and effectively protected from dam-
age. The EXTA4-* 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 electro-
static 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 EXTA4-* keyboard to a VisuNet System, keep in mind that the USB con-
nection is not hot swappable. Connect the keyboard cable when there is no voltage applied.
f 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.

Important Instructions and Manuals for Operating the Device
3.2 Function
The EXTA4-* is a keyboard/mouse combination with USB interfaces, available in different ver-
sions. The intrinsically safe keyboards integrate different mouse systems. The outside dimen-
sions besides individual mounting adapters are the same for all versions. The keyboards are
designed for panel mounting or for installation in a housing. The EXTA4-* comes with an 8-pin
connection cable or two USB connection cables.

4 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. n 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 instal-
lation regulations.
f 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 60079-
14/ EC 60079-14 must be taken into account. The "National Foreword" (Nationale Vorwort) of
D N 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.
ndividually accessible non-grounded metal parts can become electrostatically charged. The
determined capacitance exceeds the required value according to EC/EN 60079-0. The deter-
mined capacitance is specified in the technical data.
nformation on electrostatic hazards can be found in the technical specification EC/TS 60079-
32-1.
