7.8 Installing the coupling for versions with magnetic coupling
WARNING
Danger of injury from strong magnetic field
There is a risk of injury for people with pacemakers and medical implants.
► Make sure that such individuals do not enter the sphere of influence (≤ 2 m) of the magnetic field.
► Identify rooms in which magnetic couplings are openly accessible with the symbol: "
No access
for people with pacemakers
".
► Always keep disassembled couplings away from computers, data carriers, and other electronic
components.
NOTICE
Damage to the magnetic coupling due to incorrect installation and removal
The isolating shroud on the magnetic coupling is made of impact-sensitive material (synthetic or ce-
ramic).
If the motor is installed or removed incorrectly, there is a risk of damage.
► Attach the motor to the lifting gear with the eye bolt and pull the motor horizontally away from the
vacuum pump.
► Use jacking bolts and guide pins.
