ATTENTION
Faulty cross currents, incorrect measure-
ments, and even damage to the device and/or
your system due to lack of galvanic isolation!
A lack of galvanic isolation of active external cur-
rent transformers (or other current sensors) on the
multifunction channels from the supply voltage
of the device can lead to faulty cross currents,
incorrect measurements or even damage to your
device and/or system.
· Do not take the auxiliary voltage supply of
active external current transformers (or other
current sensors) on the multifunction channels
from the supply voltage of the device! For each
active current transformer, use galvanically
isolated power supplies (secondary side).
· Do not ground passive current transformers on
the multifunction channels! Observe the usage
information of the current transformer manu-
facturer.

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:
1. 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)!
2. 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.

ATTENTION
Faulty cross currents, incorrect measure-
ments, and even damage to the device and/or
your system due to lack of galvanic isolation!
A lack of galvanic isolation of active external cur-
rent transformers (or other current sensors) on the
multifunction channels from the supply voltage
of the device can lead to faulty cross currents,
incorrect measurements or even damage to your
device and/or system.
· Do not take the auxiliary voltage supply of
active external current transformers (or other
current sensors) on the multifunction channels
from the supply voltage of the device! For each
active current transformer, use galvanically
isolated power supplies (secondary side).
· Do not ground passive current transformers on
the multifunction channels! Observe the usage
information of the current transformer manu-
facturer.

INFORMATION
The functional earthing is a functional part and essential
for the regular operation of the electrical system.
INFORMATION
For a PE/N measurement, connect measuring
input A as the functional earth. Do not use a
green-yellow wire for this, as the conductor has
no protective function!
INFORMATION
Before you start with the DIN rail mounting and
cabling of your UMG 801, make sure that the
bus connector is mounted on the bottom of your
UMG 801. Then connect up to 10 modules via bus
connectors.

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:
1. 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)!
2. 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.
