5.6 Electrical Connection

DANGER

Live wires.

Risk of electrical shock.

• Electrical installation work must only be executed by qualified personnel.

NOTE

The operation with variable speed, i.e. with a variable-frequency drive or a soft starter
unit, is allowed as long as the motor is admitted and the permitted motor speed range is
neither underrun nor exceeded (see 

Technical Data [

 34]

).

Seek advice from your Busch representative.

• Make sure that the power supply for the motor is compatible with the data on the

nameplate of the motor.

• The electrical installation must comply with applicable national and international

standards.

• Provide a lockable disconnect switch on the power line so that the machine is com-

pletely secured during maintenance tasks.

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

• Busch recommends installing a D-curve circuit breaker.

• Make sure that the motor of the machine will not be affected by electric or electro-

magnetic disturbance from the mains; if necessary seek advice from Busch.

• Connect the protective earth conductor.

• Electrically connect the motor.

NOTICE

Incorrect connection.

Risk of damage to the motor!

• The wiring diagrams given below are typical. Check the inside of the terminal box for

motor connection instructions/diagrams.

5.6.1 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.

• Determine the intended direction of rotation with the arrow (stuck on or cast).

• Jog the motor briefly.

• Watch the fan wheel of the motor and determine the direction of rotation just before

the fan wheel stops.

If the rotation of the motor must be changed:

• Switch any two of the motor phase wires.
