2) Example of the installation procedures
An example of the installation procedures is shown below.
3. Moving over secondary side where primary side is installed.
1. Installing secondary side (part)
1. Installing primary side where there is no secondary side
4. Installing remaining secondary side
CAUTION
1. Installing the primary side where there is no secondary side, as shown
above, is recommended to avoid risks posed by the attraction force of the
permanent magnet between the primary side and secondary side.
2. If the primary side must be installed over the secondary side, use a material
handling device, such as a crane, which can sufficiently withstand the load
such as the attraction force.
3. Note that an attraction force will be generated even after the primary side
has been installed and is moved over to the secondary side.
