6.2 Connection of power supply
(For connector assignment see chapters 4.6.2.1 and 4.6.3.2)
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.
Information!
With the modular interface adapter, the RESET button on the front can be used to disconnect the power
supply and restart the device.
6.3 Connection of functional earth
The functional 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 compact Electronic-Key adapter.
Information!
The functional 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 in combination with functionally safe applications. The function
that can be evaluated in terms of safety engineering is the reliable detection that no Electronic-Key is
placed.
