2.5
Avoidance of electrostatic charge
The intended installation to avoid electrostatic charge must be
observed.
Failure to observe the intended installation may result in serious explosions
due to electrostatic hazards.
► The intended installation described in chapter 6.6 must be followed to
ensure proper earthing.
► The earthing of the T.VIS and the valve must be ensured.
The T.VIS E-20 is grounded by mounting it on the appropriate valves. The
conductive contact bridge to earth is established by installing the mounting
surface of the T.VIS E-20 flush with the mounting surface of the valve actuator.
Both components are clamped by two half rings.
The instructions on the warning sign of the T.VIS E-20 must be observed:
Fig.1:
Sign above: Information sign for ATEX/UKEX and IECEx certificate / sign below: Information sign for
CCCEx certificate
Explanation text sign:
WARNING - Danger due to electrostatic charge- see operating instructions!
WARNING - Do not open the control top in explosive atmospheres!*
* Relevant for use in dust protection systems
Please ensure that the T.VIS E-20 is installed as described in chapter 6.6. Make
sure that the valve is earthed via the piping.
