2 Device function
The MT-xx6-A operator interfaces are explosion-proof equipment for installation in hazardous
areas and can be installed in zones 2 and 22 with outputs for zones 1 and 21.
All devices have a modular structure, which makes changes and maintenance easy.
2.1 MT-4x6-A (Series 400 Panel PC)
The MT-4x6-A Panel PC devices are robust Panel PCs for hazardous areas. With their pre-
installed Windows operating systems they are ready to run straight away.
As a standard, all Panel PCs are equipped with a touch screen and several interfaces and are
based on the powerful ATOM technology (1.6 GHz clock frequency), making them the most
powerful devices on the market.
2.2 MT-5x6-A (Series 500 Thin Clients)
The MT-5x6-A Remote HMIs of the 500 series can be integrated into modern networks as Thin
Clients or with a KVM box via KVM-over-IP, thus providing ideal and flexible access options with
central data administration.
The MT-5x6 operator interfaces, which are used for operation and visualization, are located in
the hazardous area, whereas the PC that is operated is located in the safe area. Each
ERP/MES network can be accessed from each Thin Client via the IP address.
The Thin Client system supports both modern technologies such as DVI and USB and older
technologies such as VGA and PS/2.

10 Safety Advice
This chapter is a summary of the key safety measures. The summary is supplementary to
existing rules which staff also have to study.
The safety of persons and equipment in hazardous areas depends on compliance with all
relevant safety regulations. Thus, the installation and maintenance staff carry a particular
responsibility, requiring precise knowledge of the applicable regulations and conditions.
10.1 Installation and operation
Please note the following when installing and operating the device:
The national regulations for installation and assembly apply (e.g. EN/IEC 60079-14).
The operator interface must only be switched on when it is closed.
The installation must be compliant with any applicable regulations.
After switching the operator interface off, wait for at least 1 minute before opening it.
The safe maximum values of the connected field device(s) must correspond to the values
listed on the data sheet or the EC type examination certificate.
The operator interfaces may be installed in zones 2 or 22.
When used in zone 2 and zone 22, intrinsically safe category 2 devices or energy-limited
category 3 associated equipment may be connected to the intrinsically safe circuits.
If category 2 equipment is connected to the intrinsically safe circuits in zone 1, Um must
adhere to EN 60079-11 : 2007, section 3.16 when connecting the power supply and the
non-energy-limited circuites of the MT-xx6-A.
For the maximum connectable L and C values of the intrinsically safe circuits, the
associated (above/underneath each other) pairs of values must be applied.
National safety and accident prevention rules.
Generally accepted technical rules.
Safety instructions contained in these operating instructions.
Any damage may compromise the explosion protection !
Use the device for its intended purpose only (see "Device Function").
Incorrect or unauthorized use and non-compliance with the instructions in this manual will void
any warranty on our part.
No changes to the device that compromise its explosion protection are permitted !
The device may only be installed and operated in an undamaged, dry and clean condition !
10.2 Cautionary note
10.3 Special conditions
The fronts of the operator interfaces with a sunlight readable display (type code includes “SR”)
may be cleaned with a damp cloth only.
Caution:
This is an EN 55022 Class A product. In a domestic environment this product may cause
radio interference in which case the user may be required to take adequate measures.

11 Installation
11.1 General information
Electrical plants are subject to certain regulations concerning installation and operation
(e.g. RL 1999/92/EC, RL 94/9/EC and IEC/EN 60079-14).
It is the responsibility of the operators of electrical installations in hazardous environments to
ensure that the equipment is kept in proper condition, is operated according to instructions and
that maintenance and repairs are carried out.
11.2 MT-xx6-A
The operator interfaces may be installed in zones 2 or 22. The circuits must be installed
according to applicable regulations.
The PE connection part of the operator interface located at the back of the housing is
internally connected with the GND supply cable (X1 pins 3 and 4).
The operator interfaces can be mounted and operated in any position. Sufficient air
circulation must be ensured, however, so that the maximum operating temperature is not
exceeded.
The operator interface's front should be protected by a canopy against permanent
exposure to UV light. This increases the front membrane's lifespan. The canopy MUST
NOT be too close to the front plate and sufficient air circulation must be ensured.
The MT-4x6-A and MT-5x6-A devices may be operated at +55°C ONLY FOR SHORT
PERIODS (maximum 5 h) at a time.
Operating Instructions MT-xx6-A Installation
Page 24 of 52 OI_MT_xx6_A_SIE_en_V_03_00_01.docx / 12.02.2013
11.3 Installation via USB-interfaces
Installation of software on the operator interfaces via the USB-interfaces:
11.3.1 Software installation using a USB Flash-Drive
You may only use USB Flash-Drives permitted for use by the manufacturer. These USB Flash-
Drives are below and in general referred to by the manufacturer as "USB(i) Drives". Data may
only be copied onto the operator interfaces and software may only be installed with these USB
Drives.
In hazardous areas you may only use I.S. certified USB Drives supplied by the
manufacturer.
In an industrial area, a permitted, non-explosion proof Flash-Drive may be connected to
the I.S. USB interface of the operator interface after having been connected to any PC.
The manufacturers USB(i) drives may also be connected to non-intrinsically safe
interfaces, from where they may be used with operator interfaces of the MT-xx6-A series.
If devices are connected to the I.S. USB interface that have not been approved the
manufacturer, protective elements may become damaged, thus compromising the intrinsic
safety of the interfaces.
In this case the manufacturer can no longer guarantee the intrinsic safety of the device !
11.3.2 Software installation with external USB devices
Not applicable to MT-5x6-A
Software may be installed with the aid of any external USB devices subject to the following
conditions:
The software is installed in the safe area.
The USB devices are connected to the USB interfaces USB1 or USB3 (X5 or X7) with the
VB-USB-INST1 connection cable.
Connection diagram with VB-USB-INST1 (hard disk, CD/DVD with power supply)
Direct connections to the operator interfaces must be via VB-USB-INST1!
Otherwise, the internal circuits may become damaged and the explosion-protection of the
operator interface may become compromised !

11.4.2.1 Connection variations for Ex-nA USB interfaces
The two Ex-nA USB interfaces have an identical structure.
If intrinsically safe devices are connected to the Ex-nA USB interfaces of the MT-xx6-A
operator interfaces, the manufacturer cannot guarantee that the intrinsic safety of these
devices will continue to apply.
The following versions are possible:
1. If a USB device that is not connected to the mains is connected, voltage can be supplied
from the internal power supply (terminal 1).
2. If a USB device that is connected to the mains is connected, the internal power supply
(terminal 1) must not be connected. The power must be supplied from an external device.

Page 32 of 52 OI_MT_xx6_A_SIE_en_V_03_00_01.docx / 12.02.2013
14 Exicom-SHD-xxx hard disk
The optional Exicom-SHD-xxx hard disk can be fitted inside the MT-4x6-A operator interfaces.
* The Exicom-SHD-xxx hard disk can only be used instead of a flash memory card (SSD),
not in addition to it !
14.1 Installation of hard disk
The Exicom-SHD-xxx hard disk is mounted by the manufacturer during the production of its
operator interfaces. It is NOT possible to install the hard disks at a later date !
Installation of the Exicom-SHD-xxx hard disk into the MT-4x6-A operator interfaces
reduces the minimum operating temperature to -20°C !
The minimum temperature for the front remains -30°C.
The Exicom-SHD-xxx is incorporated into the operator interface's PA by means of two
fixing screws.
The fixing screws must be FIRMLY affixed to the housing of the operator interface to
ensure this.
The SAFE integration of the Exicom-SHD-xxx hard disk into the operator interface's PA is
guaranteed due to its factory-mounting by the manufacturer.

1999/92/EC, IEC 60079-19, EN 60079-17 and BetrSichVer (Betriebssicherheitsverordnung -
Occupational Safety and Health) !
Because the transmission of the devices remains reliable and stable over long periods of time,
regular adjustments are not required.
The following principles apply to repairs *, spare parts purchase* or exchange of parts * (where
this can be done by the user !):
Only original parts provided by the manufacturer must be used.
Fuses may only be replaced by equivalent fuse types.
* Please also note section Troubleshooting !
If the MT-xx6-A operator interfaces are stored for more than 6 months, they should be operated
every six months for at least one hour at room temperature (20°C ± 5°C).
The MT-xx6-A series operator interfaces are maintenance-free across their entire lifespan.
System maintenance should focus on the following:
a. Seal wear
b. Display damage
c. All screws are tightened fast
d. All cables and lines are properly connected and undamaged
15.1 Servicing
In accordance with IEC 60079-19 and EN 60079-17, operators of electric plants in hazardous
areas are obliged to have them serviced by qualified electricians.
15.2 Time function
Does not apply to MT-5x6-A:
When the MT-4x6-A operator interfaces are switched off, their clock function is maintained by a
battery and a capacitor. As long as the battery is intact, the clock function is maintained. Once
the battery fails, the capacitor takes over and maintains the clock function for about four days. If
the operator interface is switched on after a longer interval than that, the time and date have to
be re-set manually or via a connected system.

Operating Instructions MT-xx6-A General Information
OI_MT_xx6_A_SIE_en_V_03_00_01.docx / 12.02.2013 Page 41 of 52
19 General Information
The General Information below ONLY applies to the Panel PC Ex series of operator interfaces,
and NOT to the Thin Client Ex series.
19.1 Keyboard features
Pressing two keys at once (e.g. F1 + F7) is not supported by the operator interfaces !
In such a case, the system considers the key that was pressed first as "active" and implements
the associated functions and / or key bit functions !
The key pressed second is ignored.
Pressing any three of the following keys at the same time has the same effect as pressing
Ctrl + Alt + Del !
The keys are: F1, F2, F7 and F8.
MT-406-A only:
Pressing the S1 – S10 softkeys on the MT-406-A has the same effect as pressing the
numerical keys 0 – 9.
As an alternative, you may also allocate the Shift + F1 – Shift + F10 functions to the
S1 – S10 keys.
If this is required, it must be stated when ordering, as it can only be done by the manufacturer
before delivery.
Operating Instructions MT-xx6-A General Information
Page 42 of 52 OI_MT_xx6_A_SIE_en_V_03_00_01.docx / 12.02.2013
19.2 MT-4x6-A (Panel PC)
19.2.1 Licensing issues
The Panel PC Ex series operator interfaces are fully pre-installed with the Windows XP
Embedded, Windows XP Professional or Windows 7 Ultimate operating systems.
The license sticker is affixed on the back of the operator interface, next to the type plate.
Please note that according to the license issued for Windows XP Embedded the application of
this system as an Office PC is not permitted.
19.2.2 Recovery Stick
To restore your Panel PC device to its original state you will need a Recovery Stick, which
is available as an optional extra. This recovery stick (USB-drive, also available intrinsically
safe) contains the factory image, with which the system can be restored to delivery status
within a very short time.
Please note that you can restore the operator interfaces to their original state only with the
aid of the Recovery Stick.
As an option, the recovery stick can also contain a backup software, with which you can
back up your own device configuration.
19.2.3 Back-up
Please note that it is the sole responsibility of the operator to generate a back-up of the
operator interfaces and their overall function.
We strongly recommend such a back-up to be stored on an external storage medium
(USB stick / recovery stick, CD, DVD or similar) or on the company network.
19.2.4 Initial start-up
19.2.4.1 Initial start-up XP Pro/WIN 7
When the Panel PC operator interfaces are run for the first time with the Windows XP
Professional or Windows 7 operating systems, this requires a keyboard that must be
connected via the VB-USB-ISNT1 cable included in the delivery !
See also: Software installation with external USB devices
19.2.4.2 Initial start-up XP Embedded
When the device is started for the first time, a Wizard starts where users have to select certain
settings.
Please follow the instructions of the Wizard carefully.
Operating Instructions MT-xx6-A General Information
OI_MT_xx6_A_SIE_en_V_03_00_01.docx / 12.02.2013 Page 43 of 52
19.2.5 Switching off/closing down
The Microsoft Windows operating system stores key data in the main memory, regardless
of the application, and has to store this data on the hard disk before the PC / operator
interface is switched off.
It is therefore important for the safe and correct operation that the operator interface is
closed down properly (see illustration below) and NOT simply switched off.
Otherwise the existing image of the device may be damaged, rendering the operator
interface non-functioning.
After the data has been stored, Windows informs the user that the device can now be switched
off.
Only switch off the device once you have received this message.
19.2.5.1 Note on XP Embedded
When using the Windows XP Embedded operating system on the Panel PC series operator
interfaces, the C:\ system drive can be protected from unauthorised writing.
This is NOT the case with Windows XP Professional or Windows 7 Ultimate !
Recommendation:
In the case of applications that require constant writing into memory, the manufacturer
recommends you use external storage media (USB sticks, network servers) for these write
processes.

19.2.6 Installation Windows XP Professional
After installing the Windows XP Professional Image, the following message will pop up when
starting up the device again:
The following services are dependent on the distributed transaction coordinator service.
Stopping the distributed transaction coordinator service will also stop these services.
Message Queuing
Do you want to continue this operation ?
The MSDTC service is necessary for the SQL server, which in turn is necessary for
Siemens WinCC. For this reason, the message MUST be confirmed with YES, otherwise the
start-up of this service will fail.
