WARNING
Hot surfaces on the non-insulated low-pressure and high-pressure stage
Non-insulated low-pressure and high-pressure stages can cause serious in-
juries to personnel (burns).
ABB Turbo Systems supplies the low-pressure and high-pressure stage with
or without insulation in accordance with the purchase order received from
the enginebuilder. If supply is without insulation, the enginebuilder is re-
sponsible for providing the low-pressure and high-pressure stage with
proper insulation and for providing protection against contact with hot sur-
faces.
u
Compliance with the instructions and specifications given by the en-
ginebuilder to protect against contact with hot surfaces on the low-pres-
sure and high-pressure stage is compulsory.
Wear safety gloves to protect against thermal hazards.
Hazards due to rotating parts
WARNING
Physical hazards due to rotating parts
Contact with rotating parts can cause severe injury. The low-pressure stage
must never be used without the filter silencer or air inlet casing, respectively.
With the engine stopped, the rotor can rotate due to the stack draught
alone.
u
Operate the low-pressure and high-pressure stage in compliance with the
specifications.
u
Secure the rotor against unintentional rotation during maintenance.
Wear safety gloves to protect against mechanical hazards.
