WARNING!
Non-observance of these instructions and their contents may result in the loss of
explosion protection.
■ Battery operation:
Use only the rechargeable battery which is supplied by WIKA! Only charge the
battery outside of the hazardous area!
■ Operation of the serial interface in the hazardous area is prohibited.
Further hazardous area safety instructions!
Observe the operating information and the relevant country-specific regulations
concerning use in hazardous areas (e.g. EN IEC 60079-14).
The Pascal ET/IS intrinsically safe multichannel calibrator has been designed for use
in Ex Hazardous Areas. These are areas where potentially flammable or explosive
vapors may occur. These areas are referred to as hazardous (classified) locations in
the United States, as Hazardous Locations in Canada, as Potentially Explosive
Atmospheres in Europe and as Explosive Gas Atmospheres by most of the rest of
the world. The Pascal ET/IS intrinsically safe multichannel calibrator is designed as
intrinsically safe. This means that connecting the Pascal ET/IS intrinsically safe
multichannel calibrator to equipment that is used within intrinsically safe circuits will
not cause an ignition capable arc as long as the entity parameters are suitably
matched.
Information/Approval for hazardous locations:
WARNING!
■ Ex Hazardous Areas
An Ex-hazardous area as used in this manual refers to an area made hazardous
by the potential presence of flammable or explosive vapors. These areas are also
referred to as hazardous locations.
WARNING!
Only gauges powered by batteries are approved for use in hazardous locations.
Use only the rechargeable battery which is supplied by WIKA! Only charge the
battery outside of the hazardous area!
