Requirements

You have read and understood the general notes on installation (p. 17).

The N-470 is not connected to the electronics.

You have provided a suitable mechanical mounting (for dimensions of the linear
actuator see "Dimensions" (p. 44)):
− 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-470 must be electrically conductive.
−
The contact resistance at all connection points relevant for attaching 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-470 has a
roughness of R
a
<0.1 µm and a hardness of at least 500 HV.
−
For models with mounting thread: An M10×1 through-hole is 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 according to regulations and
without bending them.
Tools and accessories

Hook wrench (in the scope of delivery (p. 13))
When lubricant is to be applied to the contact surface of the moving part of the mechanical
mounting:

Models that are not suitable for use in a vacuum: PTFE-based grease containing no
additive

Vacuum-compatible models: Vacuum-compatible PTFE-based grease containing no
additive
