Assembly
To ensure the min. protection IP6X / NEMA 4X the keyboard module has to be
installed in a housing min. certified according to IP6X / NEMA 4X.
The keyboard module is inserted into the housing cut-out with its front side to the
exterior and fastened from the inside via mounting clips which are evenly distributed
over the external circumference of the keyboard housing in such a way that the
module is tight fitting.

Safety Instructions
General Safety Instructions
The instructions stated in this chapter are to be followed accurately to ensure a safe and reliable
operation.
The license and the special conditions included in it are to be observed.
Follow the national safety regulations and the accident prevention regulations.
The installation is only to be performed by specialists. These specialist must be familiar with the
characteristics of explosion-endangered facilities.
Incorrect or inadmissible application as well as non-observance of the instructions of this operating manual
make the guarantee void.
Only use this device for the approved purpose.
Conversions and modifications to the device are inadmissible.
The housing is only to be opened by the company Gecma Components GmbH.
Assembly
The national assembly and installation regulations are to be observed.
The generally accepted rules of engineering are to be observed.
The entire equipment is to be connected and operated correctly and properly according to the
applicable standards, guidelines and installation instructions.
The housing is to be grounded via grounding equipment. Grounding must be effected with a core cross section
of at least 4mm².
The device is only to be connected in a de-energized condition.
The intrinsically safe line system with supply and signal lines has to be effected in such a way that no error must be
considered between the individual circuits, see IEC 600-79-14, 12.2.2.8.
If the device has to be replaced in a dust atmosphere, the unit and/or the housing, in which the device is
installed, is to be de-energized first and if necessary cooled according to the regulations. Before opening the
device and/or housing and during the period in which the device and/or the housing is open, the environment of
the device and/or housing has to be kept dust-free to such an extent that no dust can enter the interior of the
housing. When installing a new device observe that all seals are in a flawless condition and function properly.
Before putting the device into operation make sure that the device has been installed as prescribed and
that the device and its wiring are not damaged.
If the power supply of the device is not intrinsically safe, the license will become void and it must not be
operated as an intrinsically safe device. If the device was operated intrinsically safely with a low level of
international protection (e.g. ib), it must not be operated afterwards in applications for a higher level of
international protection (e.g. ia).
Operation
The device is only to be operated in an undamaged and clean condition. When installed in dust
hazardous areas 2D/3D only clean the device with a wet cloth.
If the device has suffered any damages which might affect the international protection (e.g. cracks, holes
or broken components) it must be taken out of service immediately. The device can only be put into
operation again after the defect components have been exchanged.
When the keyboard is damaged, do not touch it any longer! Risk of injury!
If the device is to be used in a dust atmosphere dust layers >5mm have to be removed.
The devices (modules) may not be suspended impacts and/or frictions. High-energy load mechanisms at
the control surface of the equipment (e.g. pneumatic particle transport) are to be excluded with the use.
Only use the device for possible impacts with low risk of mechanic danger.
In the event of non-observance & non-compliance the stipulated explosion protection cannot be
guaranteed and/or the guarantee will become void!
Modifications require the written approval by the company GeCma Components GmbH.

announcement according to the technical progress.
Repair work, hazardous material
The description of the respective fault(s) is in any case to be included with the devices which
are sent to GeCma Components GmbH for repair.
The following measures are to be taken before sending a device in for repair:
Please remove the entire adhering medium residue. Pay special attention to sealing grooves
and gaps which might contain medium residue. We have to ask you to refrain from sending
the device back if it is impossible for you to definitely guarantee that all health-endangering
material has completely been removed.
Costs which arise due to inadequate cleaning of the device for a potential disposal or for
personal injury (cauterisation, etc.) will be charged to the proprietor of the device.
