8 Dismantling and fitting
The turbine casing insulation supplied by ABB Turbo Systems also serves
as burst protection
WARNING Serious injuries or accidents resulting in fatalities can occur if the turbine
casing insulation (01) supplied by ABB Turbo Systems is removed. A burst
protection is integrated in this turbine casing insulation supplied by ABB
Turbo Systems.
For turbochargers which were ordered from ABB Turbo Systems without
insulation or which are equipped with the insulation (02), a separate burst
protection (03) is fitted.
If the insulation from ABB Turbo Systems (01) is not installed, the separate
burst protection (03) plus either the insulation (02) or an appropriate
insulation supplied by the enginebuilder must be installed for operation.
Never operate a turbocharger without burst protection and insulation.
