Operating Instructions
WARNING
The specifications of the examination certificate valid in your country must be
observed.
Laws and regulations valid in your country must be observed for the electrical
installation in explosions hazardous areas. In Germany these are for example:
- Working reliability regulations
- Regulations for installing electrical equipment in hazardous areas, DIN EN
60079-14 (in the past VDE 0165, T1)
Intrinsically safe devices may only be connected to circuits certified as intrinsically
safe, which correspond to the technical data specified on the rating plate or in the
certifications and approvals (e.g. EC type-examination certificates). It should be
checked whether the available power supply is compliant with the power supply
specified on the type plate and specified in the examination certificate valid in your
country.
The interconnection of the NCS sensor with the positioner may not be led out of the
potentially explosive area, i.e the appropriate regulations must be observed.
Devices with the protection type "intrinsically safe" lose their certification as soon
as they are operated with circuits that do not conform to the specifications laid
down in the EC type examination certificate valid in your country.
Correct and safe operation of this device is dependent on proper transport, storage
and installation as well as careful operation and maintenance.
The device may be used solely for the purposes described in this manual.
Excluded Liability
The user is responsible for all changes made on the device, provided that these are
not explicitly mentioned in the operating instructions.
