Procedure
1. Remove the protective cap from the exhaust flange.
2. Observe the centering ring with nozzle including the corresponding O-rings (2×).

5.4 Establishing mains connection
DANGER
Danger to life from electric shock
Contact with exposed and live elements generate an electric shock. Incorrect connection of the mains
supply leads to the risk of live housing parts that can be touched. 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, do a PE conductor check.
NOTICE
Risk of property damage from excess voltage
Incorrect or excessive mains voltage will destroy the motor.
► Always observe the motor rating plate specifications.
► Route the mains connection in accordance with locally applicable provisions.
► Always provide a suitable mains fuse to protect the motor and supply cable in the event of a fault.
