Connection of power supply

(For information on connector assignment, see chapter 4.3.2.1 Connection of power supply)
It is imperative that the following points are observed:
The connections must be made as appropriate to maintain EMC performance.
A power supply of suitable EMC performance must be used for the power supply.
Conductor cross-section maximum 1.5 mm².
Tighten the screws on the terminal plug to 0.22 Nm.
6.3 Connection of function earth
The function earth is connected via terminal 3 on the plug-in screw terminals for the power supply. This
connection is electrically connected internally to the housing of the Electronic-Key adapter.
Information!
The function earth must be connected to PE!
6.4 Connection of the semiconductor switching contacts (for EKS FSA
only)
Warning!
Incorrect connection or errors in the safety-related integration of the EKS FSA can lead to fatal injury.
For this reason, observe the following safety aspects:
 It is not possible to generate a safe signal by using only the switching contacts LA1/LA2 and
LB1/LB2. Safe, downstream evaluation is always necessary. Use of the switching contact LB1/LB2
(for the compact version only) is optional.
 Safe evaluation must always be dual-channel:
Evaluation of switching contact LA1/LA2 as channel LA together with evaluation of the data line as
channel LB.
Information!
The switching contact LA1/LA2 is used with functionally safe applications. The function that can be
evaluated in terms of safety engineering is the reliable detection that an Electronic-Key has not been
placed.
