Your measurement device has two Ethernet
interfaces (A and B) for communication in Ether-
net networks. There are 2 options to integrate the
measurement device into Ethernet networks:

Measurement device integration in a network
with additional switch function (switched
mode).

The measurement device is automatical-

ly assigned an IP address by a DHCP server in
an IT network via Ethernet interface A, for exam-
ple. Ethernet interface B has a switch function
via which further devices (hardware components)
can be connected in series. The measurement
device also allows the reverse use of the Ether-
net interfaces (e.g. "B" for the IP address from a
network and "A" for further devices)!

Measurement device integration in 2 different
networks (dedicated mode)

The Ethernet interfaces A and B of the mea-
surement device are each assigned different IP
addresses by 2 different networks.

Potential isolation and electrical safety of the interfaces

The interfaces (RS-485, Ethernet) have:

• Double insulation to the inputs of the voltage and current

measurement.

• Functional insulation relative to each other, to the supply

voltage, to the measuring inputs for residual current and tem-

perature, to the digital inputs/outputs and to the analog output.

The interfaces of the connected devices require double or

reinforced insulation against mains voltages (according to IEC

61010-1: 2010).

Potential isolation and electrical safety of the

multifunction channels (RCM, Temp.)

The inputs of the multifunction channels have:

• Double insulation to the inputs of the voltage and current

measurement.

• Double insulation to the inputs of the voltage and current

measurement.

• Functional insulation relative to each other, to the supply

voltage, to the measuring inputs for residual current and tem-

perature, to the digital inputs/outputs and to the analog output.

The interfaces of the connected devices require double or

reinforced insulation against mains voltages (according to IEC

61010-1: 2010).

Potential isolation and electrical safety of the

multifunction channels (RCM, Temp.)

The inputs of the multifunction channels have:

• Double insulation to the inputs of the voltage and current

measurement.

• No insulation to each other or to the supply voltage.

• Functional isolation to the Ethernet, RS-485 interfaces, to the

digital inputs/outputs and to the analog output.

External sensors and/or transformers require double insulation

relative to system components with dangerous touch voltages

(according to IEC61010-1:2010).

• Double insulation to the inputs of the voltage and current

measurement.

• Functional insulation relative to each other, to the supply

voltage, to the measuring inputs for residual current and tem-

perature, to the digital inputs/outputs and to the analog output.

The interfaces of the connected devices require double or

reinforced insulation against mains voltages (according to IEC

61010-1: 2010).

multifunction channels (RCM, Temp.)

The inputs of the multifunction channels have:

• Double insulation to the inputs of the voltage and current

measurement.

• No insulation to each other or to the supply voltage.

• Functional isolation to the Ethernet, RS-485 interfaces, to the

digital inputs/outputs and to the analog output.

External sensors and/or transformers require double insulation

relative to system components with dangerous touch voltages

(according to IEC61010-1:2010).
