FlexBar HRT Pressure Transmitter
Safety instructions
This instrument is built and tested according to the current EU-directives and packed in technically safe condition. In order to maintain this
condition and to ensure safe operation, the user must follow the hints
and warnings given in this instruction.
During the installation the valid national rules have to be observed.
Ignoring the warnings may lead to severe personal injury or substantial
damage to property.
The product must be operated by trained staff. Correct and safe
operation of this equipment is dependent on proper transport, storage,
installation and operation.
All electrical wiring must conform to local standards. In order to prevent
stray electrical radiation, we recommend twisted and shielded input
cables, as also to keep power supply cables separated from the input
cables. The connection must be made according to the connecting
diagrams.
Before switching on the power supply take care that other equipment
is not affected. Ensure that the supply voltage and the conditions in the
environment comply with the specification of the device.
Before switching off the supply voltage check the possible effects on
other equipment and the processing system.
WARNING
For electrical installation and commissioning of explosion protected
devices, the data given in the conformity cer tificate as also the local
regulations for installation of electrical apparatus within explosion protected areas must be considered. The intrinsically safe versions can be
mounted in the explosion hazarded area according to its specification
only connected to a certified intrinsically safe supply loop with the corresponding electrical values.
