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
9.9 Installation instructions
Electrostatic discharge
The device contains components that can be damaged or destroyed by
electrostatic discharge When handling the device, observe the necessary safety
precautions against electrostatic discharge (ESD) according to EN 61340-5-1 and
IEC 61340-5-1
Damage to the electronics
► The device may only be installed and removed by qualified electricians in accordance with the
ESD regulations
► Implement the FE connection using mounting screws, in order to ensure immunity to interference
► To ensure IP65/IP67 protection, cover unused connections with protective caps
► Only supply the sensors with the voltage U
► Avoid polarity reversal of supply voltages U
Data corruption or loss
► Implement the FE connection using mounting screws, in order to ensure immunity to interference
9.10 Mounting distances
No specific distances are required between devices or between a device and a
cabinet door or cover Mounting distances are determined solely by the plugs used
and the bending radii of the cables
