The replacement of components may compromise the explosion
protection. Service and repair must be carried out by the manufacturer.

2.4 Special hazards

WARNING!
Observe the information given in the applicable type examination
certificate and the relevant country-specific regulations for installation
and use in hazardous areas (e.g. IEC 60079-14, NEC, CEC).
Non-observance can result in serious injury and/or damage to
equipment.
For additional important safety instructions for instruments with ATEX
approval see chapter 2.3 "Additional safety instructions for instruments
per ATEX".
WARNING!
Pressure sensors should only be mounted or dismounted when the
system is free from pressure.
Observe the working conditions in accordance with chapter
3 "Specifications".
Always operate the pressure calibrator within its overload limits. See
chapter 3 "Specifications".
Do not apply a voltage greater than the specified voltage to the
instrument. See chapter 3 "Specifications".
Residual media on the dismounted calibrator and/or sensors can
result in a risk to persons, the environment and the equipment. Take
sufficient precautionary measures.
Only use those accessories available from WIKA for the calibrator.
Make sure that the test probes never contact a voltage source while
the test cables are connected to the current terminals.
The measurement signal of the reference (or test sample) can be
influenced by large electromagnetic effects and the display of the
signal may be lost completely.
