NOTICE

Heating up of the drive during operation!

The heat produced during operation of the drive can affect your application.



Install the drive so that the application is not affected by the dissipated heat.



Ensure sufficient ventilation at the place of installation.



Make sure that the complete drive is underneath in contact with the surface on which the

drive is fixed.

NOTICE

Damage due to collisions!

Collisions can damage the drive, the load to be moved, and the surroundings.



Make sure that no collisions are possible between the drive, the load to be moved, and the

surroundings in the motion range of the drive.



Do

not

place any objects in areas where they can be caught by moving parts.

INFORMATION

For the positive direction of motion of the runner, see "Product View" (p. 7).

Connecting the N-331 to a Protective Earth Conductor

INFORMATION

Pay attention to the applicable standards for mounting the protective earth conductor.

The drive features a separate protective earth connection, see “Dimensions” on p. 24.
