Provide a lockable disconnect switch on the power line so that the machine is completely secured
during maintenance tasks.

Provide an overload protection according to EN 60204-1 for the motor.

Connect the protective earth conductor.

Electrically connect the motor.

6.2

Machine delivered with a Variable Speed Drive
(Option)

If the machine is equipped with a power connector, install a residual current protective device to
protect persons in case of isolation default.

Busch recommends installing a type B residual protective device suitable for the electrical in-
stallation.

If the variable speed drive is not equipped with a lockable disconnect switch, provide it on the
power line so that the machine is completely secured during maintenance tasks.

Provide an overload protection according to EN 60204-1.

Connect the protective earth conductor.

NOTICE

Incorrect connection.
Risk of damage to the variable speed drive!

The wiring diagrams given below are typical. Check the connection instructions/diagrams.

Wiring Diagram Three-Phase Motor

NOTICE

Incorrect direction of rotation.
Risk of damage to the machine!

Operation in the wrong direction of rotation can destroy the machine in a short time! Prior to
start-up, ensure that the machine is operated in the right direction.

NOTICE

Incorrect direction of rotation.
Risk of damage to the vacuum system!

Operating the vacuum system with the rotation in the wrong direction can result in the operating
liquid flowing back to the vacuum system. Prior to start-up, check for correct direction of rotation.

If the rotation of the motor must be changed:

Switch any two of the motor phase wires.
