1 Safety information

1.1 Intended use

The motor is used to generate a rotational movement. It is intended for use as a drive system in

commercially used plant and machinery.

The motor is exclusively intended for operation with frequency inverters.

The motor may not be used in environments in which an explosive atmosphere can occur.

The motor has been designed with at least protection class IP55 (see name plate for protection class).

The motor can be installed in dusty or humid environments. Depending on the conditions of use and

the environment, additional protective measures may be necessary.

The motor must not be operated until it has been established that the plant or machinery can be safely

operated with the motor. If motor operation, motor fault or failure could result in a risk to persons,

suitable protective measures must be provided.

The motor may only be used as intended and according to the information in this manual. Pay

particular attention to section 2.4 "Requirements for the use of the drive".

1.2 Do not make any modifications.

Unauthorised changes and the use of spare parts and additional equipment that has not been

purchased from or recommended by NORD may cause fire, electric shock and injury.

Do not make any modifications to the drive. Do not remove any protective devices.

1.3 Only use in perfect condition

Only operate the drive if it is in technically perfect condition and if all associated protective devices are

present and functional.

Take care that no components are bent, no insulation distances are changed and that no electrical

components are mechanically damaged or destroyed during transport or handling.

1.4 Performing inspection and maintenance work

Due to lack of maintenance and damage, malfunctions may occur which can result in personal injury.

• Carry out all servicing and maintenance work at the specified intervals.

• Also note that servicing is necessary after long storage periods prior to commissioning.

• Do not operate damaged drives The drive must not have any leaks.
