Connecting the protective earth conductor to the separate protective earth
connection
Figure 8: Recommended mounting of the protective earth conductor (profile view)
1 Base body of the drive
2 Flat washer
3 Safety washer
4 Screw
5 Cable lug
6 Protective earth conductor
1. If necessary, attach a suitable cable lug to the protective earth conductor.
2. Use the M4 screw (together with the washers and self-locking washers) to affix the cable
lug of the protective earth conductor to the protective earth connection of the drive as
shown in the profile view.
3. Tighten the M4 screw with a torque of 1.2 Nm to 1.5 Nm.
4. Make sure that the contact resistance at all connection points relevant for connecting the
protective earth c onductor is <0.1 Ω at 25 A.
Integrating the N-331
The mounting holes in the underneath of the base body and at both ends of the runner make it
possible to integrate the drive into an assembly.
Fixing the N-331 by Its Base Body
NOTICE
Warping of the drive due to mounting on uneven surfaces and lateral forces!
Mounting the drive onto an uneven surface can warp the drive. Lateral forces on the runner
can warp the runner. Warping reduces the specifications of the drive.

Mount the drive onto an even surface. The recommended evenness of the surface
is ≤20 µm.

For applications with large temperature changes:
Only mount the drive onto surfaces that have the same or similar thermal expansion
properties as the drive.

Runner and movable part of the assembly, where the drive is to be integrated in, have to
be parallel.
