5.5 Establishing mains connection
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
Danger to life from electric shock in the event of a fault
In the event of a fault, devices connected to the mains may be live. There is a danger to life from
electric shock when making contact with live components.
► Always keep the mains connection freely accessible so you can disconnect it at any time.
CAUTION
Risk of injury from trapping of body parts due to unexpected automatic startup
With open control input, the motor can start unexpectedly following extrinsic contact, if the mains volt-
age is already applied.
A risk exists of minor injury to fingers and hands (e.g., hematoma), from direct contact with the vac-
uum flange.
► Note the prescribed switch-on procedure for safe startup.
CAUTION
Risk of injury from trapping of body parts due to unexpected automatic startup
When connecting the power cable, the motor can start unexpectedly if the control cable is already
connected to an activated on-site contact.
A risk exists of minor injury to fingers and hands (e.g., hematoma), from direct contact with the vac-
uum flange.
► Note the prescribed switch-on procedure for safe startup.
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.
