You have provided a suitable mechanical mounting (for dimensions of the linear drive
see “Dimensions”, p. 23):
−
The mechanical mounting must be connected to the protective earth conductor.
−
The contact surface of the mechanical mounting to the mounting nut or thread or
clamping shank of the N-412 must be electrically conductive.
−
The contact resistance at all connection points relevant for mounting the
protective earth conductor is <0.1
Ω
at 25 A.
−
The contact surface of the mechanical mounting to the ball tip of the N-412 has a
roughness of Ra <0.1
μ
m and a hardness of at least 500 HV.
−
For models with mounting thread: An M10×1 through-hole is present in the
mechanical mounting.
−
For models with clamping shank: There is a through-hole with a suitable diameter
in the mechanical mounting.
You have accounted for the space required to route cables without bending and
according to regulations.

Installing an N-412.50 (with clamping shank)
1.
Optional: Apply a small amount of lubricant to the contact surface of the moving part of
the mechanical mounting.
2.
Remove the mounting nut from the clamping shank of the N-412.
3.
Position the N-412 in the mechanical mounting of your application.
4.
Manually screw the mounting nut of the N-412 a few turns into the thread of the
clamping shank.
5.
Align the base body with the mechanical mounting.
6.
Clamp the N-412 firmly in the mounting:
−
Hold the base body and hand-tighten the mounting nut of the N-412 with the hook
wrench.
7.
Check that the linear drive is affixed firmly in the mounting.
8.
Make sure that the contact resistance at all connection points relevant for connecting
the protective earth conductor is <0.1
Ω
at 25 A.
