4.3 Electrical Connectors
4.3.1 Introduction
All installation work has to be carried out by qualified person-
nel and according to appropriate regulations.
The electrical connections have to be carried out using the
connection diagram in the appendix. Since this is an applica-
tion-specific document, it has to be ensured, that the correct
document (correct version of this manual) ist being used.
The device may only be energized when the installation has
been successfully completed. Always connect the mains last.
4.3.2 Magnetic Bearing Connectors
In order to operate the magnetic bearings, both bearing mag-
nets and sensors must be connected to the device. For the
sensors there are two options: For cable lengths up to 23
meters without additional SMX6B-amplifier, for variable cable
lengths from 2 to 31 meters with SMX6B-amplifier mounted on
the blower.
Always be sure to properly connect the shielding and to fasten
the cables tightly on to the mounting rail.
