4.9 Connecting the electrical supply
DANGER
Danger to life from electric shock
Touching exposed and voltage-bearing elements causes an electric shock. Improper connection of
the mains supply leads to the risk of touchable live housing parts. There is a risk to life.
►
Before the installation, check that the connection leads are voltage-free.
►
Make sure that electrical installations are only carried out by qualified electricians.
►
Provide adequate grounding for the device.
►
After connection work, carry out an earthed conductor check.
WARNING
Risk of injury due to incorrect installation
Dangerous situations may arise from unsafe or incorrect installation.
►
Do not carry out your own conversions or modifications on the unit.
►
Ensure the integration into an Emergency Off safety circuit.
WARNING
Risk of danger to life through missing mains disconnection device
The vacuum pump and electronic drive unit are not equipped with a mains disconnection device
