Safety Advices
Keyboard surface
The silicone case wall is generally thicker than 5 mm, but much less around
the keys and above of the lamps (under the keys “Num” and “
“and between
the keys “Esc” and “1”). Even hardly visible damages may decrease the IP
protection here and make the dust protection become invalid. Please watch
these areas.
Cleaning
only outside of hazardous areas because of possible charging of the cleaning
tool. No dry cleaning inside of hazardous areas.
In general
Read the manual completely and carefully before operation. Only the latest
documentation is valid.
If it can be assumed that safe operation is no longer possible, switch off the
unit and secure it against being used again.
Installation, maintenance and cleaning of the units must only be performed by
persons trained and authorized for this purpose, insofar as they are familiar
with the units.
It is prohibited for the operator or his staff to open the units in a way that is not
described in this manual. This may only be done by specifically authorized
personnel of E.L.B. Ex-Geraete GmbH & Co. KG.
Modifications and conversions to the units are not permissible and will cause
the Ex protection and the guarantee to become void.
E.L.B. Ex-Geraete GmbH & Co. KG is not liable for any consequential
damage.
The technical data specified for hazardous areas comply with the values
certified in the European Ex approval. The user bears the sole responsibility of
examining the equipment with regard to its suitability for the intended
application and environmental conditions. E.L.B. Ex-Geraete GmbH & Co. KG
accepts no liability for any lack of suitability.
