Intended use

Use on internal combustion engines in general
ABB turbochargers are intended for charging internal combustion engines.
To ensure compliance with the machinery directive 2006/42/EC when using on gas engines,
the turbocharger must be operated in an engine room classified as "not at risk of explosion".
This is in accordance with the position paper [2] relating to ATEX issued by EUROMOT [1].
For use on pre-mix gas engines with ignitable propellents in the gas control system, the en-
ginebuilder must implement appropriate safety measures for explosion protection [3] (such
as flame barriers in the inlet system, for example) to assure that there is no transient pres-
sure increase exceeding a maximum of 12 bar before the turbocharger in case of a deflagra-
tion.
The turbocharger supplies the engine with the air volume or air/gas mixture and the associ-
ated charging pressure required for operation.
The turbocharger is solely intended to be operated with a clockwise direction of rotation as
viewed from the turbine end.
The specific operating limits of the turbocharger were determined on the basis of informa-
tion from the enginebuilder about the intended use. These data are given on the rating
plate.
ABB accepts no liability and rejects all warranty claims for any non-intended uses.
