WARNING
Absence of grounding on electrical installations
Missing or incorrectly fitted grounding conductors can lead to severe injury
to personnel or accidents resulting in fatalities.
Electric shock or elevated electromagnetic disturbances can damage or des-
troy electrical and electronic components.
Ground electrical installations properly with grounding conductors.
u
Check the grounding connections on a regular basis and make sure they
u
are properly connected.
Switch off the power supply before working on any electrical installations.
u
After switching off the power supply, wait for 5 minutes to allow capacitors to discharge
u
and hot components to cool down.
Ensure the power supply is switched off when working on electrical installations.
u
Do not carry out any tests with regard to insulation resistance or voltage on the electrical
u
components.

Safe operation

Mechanical hazards during operation
During standard operation, no mechanical hazards are caused by the turbocharger itself if it
has been properly installed.
Safety during commissioning and operation
Visually inspect your working environment before starting work.
u
Remove any obstacles and objects littering the workplace.
u
Check all pipes to and from the turbocharger for damage and leaks before commission-
u
ing.
Check turbocharger for recognisable damage or defects every 12 hours of operation or at
u
least once a day.
Report any damage and any alterations of operational characteristics to the responsible
u
department immediately.
In case of damage, take the turbocharger out of operation immediately and safeguard
u
against accidental/unauthorised use.
When switching on operating energy supplies (hydraulics, pneumatics, electricity), pay at-
u
tention to the risks that may occur as a consequence of this energy input.
