WARNING!

All activities described in this chapter must be performed by qualified, authorised personnel
only under observance of requirements from the following regulating bodies:



Official Journal of the European Union L 96/309, Directive 2014/34/EU of 26 February
2014 relating to equipment and protective systems intended for use in potentially
explosive atmospheres (recast)



EN 60079-0:2014-06 (VDE 0170-1:2014-06) Explosive atmospheres – Part 0:
Equipment – General requirements

DANGER!

For ignition attempts for maintenance purposes, there is a risk of flashing
caused by residual gas in the gas tube or gases in the environment.



For pilot attempts, secure the hazard area in front of the pilot burner mouth.



Clear the pilot burner with purge air from residual gas as necessary.



The ignition should ideally only be tested in installed status.

WARNING!

Opening the housing of the integrated power unit Ex-Zone II is not permitted!
This does not affect the opening of the tube to replace the wearing parts.
