Q-521 Miniature Linear Stage
INFORMATION
The electrical contact of the Q-521 to the protective earth conductor is established via the
surface, on which the Q-521 is mounted.
The corresponding contact surfaces must be sufficiently conductive.
The protective earth conductor is connected to the surface on which the Q-521 is
mounted.
The screws are secured against unintentional loosening; e.g., with thread-locking adhesive.
INFORMATION
Pay attention to the applicable standards for mounting the protective earth conductor.
You have the following options for fastening the Q-521:
From above with 2 M2x6 screws
From below with 4 M2 screws of suitable length
Requirements
You have read and understood the general notes on installation (p. 17).
The Q-521 is disconnected from the electronics.
You have provided a suitable surface (for the required position and depth of the holes
for accommodating the screws and locating pins, see "Dimensions" (p. 54)):
−
The surface must be connected to the protective earth conductor.
−
The contact surfaces to the bottom side of the linear stage have to be sufficiently
conductive to ensure the proper functioning of the protective earth conductor.
−
The contact resistance at all connection points relevant for mounting the protective
earth conductor is <0.1
Ω
at 25 A.
−
For applications with large temperature changes: The surface should have the same
thermal expansion properties as the Q-521 (e.g., surface made of steel).
−
The evenness of the surface is ≤2 µm.
You have accounted for the space required to route cables without bending and
according to regulations.
