Safety

1 Safety

1.1 General

Responsibility for planning, assembly, commissioning, operation, maintenance, and dismount­ing lies with the plant operator.

Installation and commissioning of all devices may be performed only 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 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 Housings and Surrounding Enclosures

1.5.1 Degree of Protection

To ensure the degree of protection:

• The housing must not be damaged, distorted or corroded.

• All seals must be undamaged and correctly fitted.

• All screws of the housing/housing cover must be tightened with the appropriate torque.

• All cable glands must be suitably sized for the incoming cable diameters.

• All cable glands must be tightened with the appropriate torque.

• All unused cable glands must be sealed and closed with appropriate sealing plugs or

stopping plugs.

1.6 Repair and Servicing

The device must not be repaired, changed, or manipulated. In case of failure, always replace
the device with an original device.

1.6.1 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.

1.7 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.

1.8 Use

1.8.1 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 must only be operated in the specified ambient temperature range and at the spec­ified relative humidity without condensation.

When using stranded conductors, crimp wire end ferrules on the conductor ends.

1.8.2 Improper Use

Protection of the personnel and the plant is not ensured if the device is not used according to its
intended use.

1.9 Intended Use of the EXTA3 Keyboard

EXTA3 is a PC keyboard with an optional operating element for mouse functions (capacitive or
resistive touch pad, mechanical and optical trackball mouse, joystick). The keyboard has USB
interfaces for intended use in hazardous areas, Class I/Division 2, Class II, Division 2, and
ATEX Zone 2 and Zone 22 areas according to ATEX Directive 2014/34/EU and IECEx. The
USB interfaces of the keyboard and the operating element for mouse functions are separate,
intrinsically safe circuits. Both intrinsically safe circuits are routed to the outside via one or two
separate connection cables. The connection cable corresponds to type "B" in accordance with
IEC 60079-14, Section 12.2.2.8. The cable must be secured and protected effectively against
damage. The EXTA3 keyboard must not be installed in locations where corrosive media are
used.

To prevent discharges, the keyboard may only be installed in areas with a low risk of strong
electrostatic charges caused by dust. To prevent electrostatic charge, foils must not cover or be
stuck onto the keyboard.

The keyboard must not be exposed to direct sunlight.

When connecting keyboard EXTA3 to a VisuNet RM/PC, ensure that the USB connection is not
changed during operation. The keyboard cable must be connected when it is in a de-energized
state.

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.

Standalone applications require an I.S. barrier based on the Entity concept. Pepperl+Fuchs'
model number for this I.S. barrier is SK-PC-D2-UU1-10-HS.
