Ethernet interfaces
61292
Communication interfaces are insulated from each other, from other circuits and from touchable device
surfaces by means of basic insulation according to IEC 62368-1 (secondary circuit with max. operating
voltage (→ Data sheet), supplied from the mains circuit up to 300 V of overvoltage category II).
They are defined as ES1 circuits.
► Use a screened CAT5 cable.
▪
STP (shielded twisted pair), according to EIA/TIA-568.
▪
Max. length 25 m
The max. cable length depends, for example, on the bus topology, the selected operating
mode (10/100 Mbits/s) or the quality of the connectors.
► Use screened connector housings and connect the screen of the Ethernet cable to the connector
housing.
► Do not lay the Ethernet cable in parallel to live cables.
Interference due to external influences
Faulty or insufficient radio interference suppressors in other electrical equipment, such as
inverters as well as voltage fluctuations when switching on/off electric loads may lead to
problems with the data transmission.

USB interfaces
61293
Wiring (→ Data sheet)
This USB interface is connected to a USB connector (art. no.: EC2099). It is used for the connection of
USB 2.0 devices.
The supply of external USB devices via the USB interface is protected against overload. Max.
continuous current: 500 mA
USB connection via M12 connector
1: AE1300
2: USB connector
3: USB device, e.g. LTE stick
