Commissioning and first steps
25/166
Functional earth
The device's power supply connector and the Ethernet connector have FE
(functional earth) pins that are connected to the mounting hole of the
device. You can ground the device as follows:
·
Grounding via the mounting hole if the device is mounted on a
conductive surface
·
Grounding via a cable lug and the mounting hole if the device is
mounted on a non-conductive surface.
·
Grounding via FE of the power supply connection
Make sure that the contacts are properly connected and that the cross-
section of the cable is sufficient!

Power supply requirements
Note the following about the power supply of the sensorEDGE device:
Risk of electric shock
To avoid the risk of an electric shock, use only 24 V DC SELV (Safety Extra
Low Voltage) or PELV (Protective Extra Low Voltage) systems for the
voltage supply of your device!
Risk of device destruction by exceeding allowed current
The current of the power supply of the device must not exceed 16 A !
Always protect the power supply with a circuit breaker or fuse. For this
purpose, use a 24 V DC / max. 16 A fuse or circuit breaker with type B trip
characteristics.
Risk of device destruction by exceeding the allowed supply voltage
The device may only be operated with the specified supply voltage of 24 V
DC (± 6 V DC). Make sure that the limits of the allowed range for the supply
voltage are not exceeded.
Ø
Supply voltage above the upper limit can cause severe device damage.
Ø
Supply voltage below the lower limit can cause malfunction of the
device.
Ø
Supply voltage below appr. 10 V can cause a device reset.
