6 Startup and Operation
N-412 Piezo Motor Rod Drive N412T0001 Version: 1.2.1 15
5.4 Installing an N-412.51 (with mounting thread)
1. Screw the mounting nut of the N-412 as far as necessary in the direction of the base
body of the N-412.
2. Optional: Apply a small amount of lubricant to the contact surface of the moving part of
the mechanical mounting.
3. Screw the N-412 as far as necessary into the M10×1 through-hole of the mechanical
mounting.
4. Align the base body of the N-412 with the mechanical mounting.
5. Fix the N-412 in the mechanical mounting:
a)
Hold the base body and screw the mounting nut of the N-412 in the direction of the
mechanical mounting.
b) Hand-tighten the mounting nut with the hook wrench.
6. Check that the linear drive is affixed firmly in the mounting.
7. Make sure that the contact resistance at all connection points relevant for connecting
the protective earth conductor is <0.1
Ω at 25 A.
6 Startup and Operation
6.1 General Notes on Startup and Operation
CAUTION
Risk of electric shock if the protective earth conductor is not connected!
If a protective earth conductor is not or not properly connected, dangerous touch voltages can
occur on the N-412 in the event of malfunction or failure of the system. If touch voltages exist,
touching the N-412 can result in minor injuries from electric shock.

Connect the N-412 to a protective earth conductor (p. 13) before startup. To do this, install
the N-412 onto a sufficiently conductive mechanical mounting that is connected to a
protective earth conductor.

Do not remove the protective earth conductor during operation.

If the protective earth conductor has to be removed temporarily (e. g., in the case of
modifications), reconnect the N-412 to the protective earth conductor before starting it up
again.
CAUTION
Risk of crushing by moving parts!
There is a risk of minor injuries caused by crushing which can occur between the moving part
of the linear drive and a stationary part or obstacle.

Keep your fingers away from areas where they can get caught by moving parts.
