9.7 Surge protection measures
ifm recommends wiring relay coils or motor coils to an RC element in order to protect the devices
against interference� Depending on the application, the delay time of the relay can be increased by
approximately 1 ms�
Relay coil with RC element
For the dimensioning of the RC element, the following values are recommended:
R = 100���200
Ω /
C = 220���470 nF
9.8 Grounding concept
The devices operate in the low-level signal voltage range� In the case of low-level
signal devices, interference is discharged via functional earth (FE)� Functional
earth (FE) is only used to discharge interference� It does not provide shock
protection for people�
Functional grounding
The devices are designed to be screwed onto a flat mounting surface�
► Ground the devices by means of the mounting screws of the fixing clips�
