Voltage measurement in the three-phase
four-conductor system (TN, TT networks).
Note: Earth your system! Voltage measurement in the three-phase three-
conductor system (IT network).
The device is only suitable for use in IT networks
to a limited extent, as the measured voltage
relative to the housing potential is measured and
the input impedance of the device creates residual
current against the earth. The residual current can
trigger insulation monitoring in IT networks.
Connection variants with voltage transformers
are suitable for IT networks without
restrictions!
Schematic diagram for voltage measurement
Fig. Schematic diagram, device in an IT network without N.
Current measurement
The device
• is intended for connecting current
transformers with secondary currents
of ../1 A and ../5 A.
• does not measure DC.
• has current measurement inputs that can
be loaded with a maximum of 120 A for
1 second.

The device has 3 types of address allocation for the
Ethernet interface (TCP/IP) in
DHCP mode:
1. OFF (fi xed IP address)
The user selects the IP address, network mask
and gateway on the device. Use this mode for
straightforward networks without DHCP servers.
2. BOOTP
Automatically integrates your device into an
existing network. BOOTP is an older protocol and
has a smaller scope of functions than DHCP.
3. DHCP
When started, the device automatically receives
the IP address, the network mask and the gateway
from the DHCP server.
Standard setting for the device is DHCP!

WARNING!
Risk of injury due to electric
voltage!
Severe bodily injuries or death can occur due
to:
• touching bare or stripped wires that are
live,
• current measurement inputs that are
dangerous to touch on the device and on
the current transformers.
De-energise your device before starting
work! Check that it is de-energised.
Earth the system. To do this, use the earth
connection points with the earthing symbol.
Also earth the secondary windings on the
current transformer and all metal parts on
the transformer that are able to be touched.

RECOMMENDATION!
For a PE/N measurement, connect the
protective earth (PE) to measurement
input V4. Do not use a green and yellow
wire for this as the conductor does not
have any protective function!
The voltage measurement inputs are designed for
measurements in low voltage networks, in which the
following rated voltages occur:
• Per IEC - 417 V phase to earth and 720 V phase
to phase in the 4-conductor system.
• Per UL - 347 V phase to earth and 600 V phase to
phase in the 4-conductor system.
• 600 V phase to phase in the 3-conductor system.
The measurement and surge voltages meet
overvoltage category 600 V CATIII.
User manual:
The device is a class A power quality analyser
that
• measures and calculates electrical variables
such as voltage, current, power, energy,
harmonics, etc. in building installations,
on distribution units, circuit breakers and
busbar trunking systems.
• measures and monitors residual currents
(RCM) and currents at the central
grounding point (CGP). The residual current
monitoring is carried out via an external
residual current transformer (30 mA rated
current) on the current measurement inputs
I5 and I6.
• displays measurement results and transmits
them via interfaces (Ethernet, Modbus,
Profi bus).

Voltage measurement in the three-phase
four-conductor system (TN, TT networks).
Note: Earth your system! Voltage measurement in the three-phase three-
conductor system (IT network).
The device is only suitable for use in IT networks
to a limited extent, as the measured voltage
relative to the housing potential is measured and
the input impedance of the device creates residual
current against the earth. The residual current can
trigger insulation monitoring in IT networks.
Connection variants with voltage transformers
are suitable for IT networks without
restrictions!

The device has 3 types of address allocation for the
Ethernet interface (TCP/IP) in
DHCP mode:
1. OFF (fi xed IP address)
The user selects the IP address, network mask
and gateway on the device. Use this mode for
straightforward networks without DHCP servers.
2. BOOTP
Automatically integrates your device into an
existing network. BOOTP is an older protocol and
has a smaller scope of functions than DHCP.
3.
DHCP
When started, the device automatically receives
the IP address, the network mask and the gateway
from the DHCP server.
Standard setting for the device is DHCP!

WARNING!
Risk of injury due to electric
voltage!
Severe bodily injuries or death can occur due
to:
• touching bare or stripped wires that are
live,
• current measurement inputs that are
dangerous to touch on the device and on
the current transformers.
De-energise your device before starting
work! Check that it is de-energised.
Earth the system. To do this, use the earth
connection points with the earthing symbol.
Also earth the secondary windings on the
current transformer and all metal parts on
the transformer that are able to be touched.

RECOMMENDATION!
For a PE/N measurement, connect the
protective earth (PE) to measurement
input V4. Do not use a green and yellow
wire for this as the conductor does not
have any protective function!
The voltage measurement inputs are designed for
measurements in low voltage networks, in which the
following rated voltages occur:
• Per IEC - 417 V phase to earth and 720 V phase
to phase in the 4-conductor system.
• Per UL - 347 V phase to earth and 600 V phase to
phase in the 4-conductor system.
• 600 V phase to phase in the 3-conductor system.
The measurement and surge voltages meet
overvoltage category 600 V CATIII.
User manual:
The device is a class A power quality analyser
that
• measures and calculates electrical variables
such as voltage, current, power, energy,
harmonics, etc. in building installations,
on distribution units, circuit breakers and
busbar trunking systems.
• measures and monitors residual currents
(RCM) and currents at the central
grounding point (CGP). The residual current
monitoring is carried out via an external
residual current transformer (30 mA rated
current) on the current measurement inputs
I5 and I6.
• displays measurement results and transmits
them via interfaces (Ethernet, Modbus,
Profi bus).
m
CAUTION!
Damage to property due to
not observing the installation

Voltage measurement in the three-phase
four-conductor system (TN, TT networks).
Note: Earth your system! Voltage measurement in the three-phase three-
conductor system (IT network).
The device is only suitable for use in IT networks
to a limited extent, as the measured voltage
relative to the housing potential is measured and
the input impedance of the device creates residual
current against the earth. The residual current can
trigger insulation monitoring in IT networks.
Connection variants with voltage transformers
are suitable for IT networks without
restrictions!

NOTE!
Further information on
• supporting measurements via inputs
V4 (L4) and I4, and
• current data and current transformer
data
is provided in the user manual.

The device has 3 types of address allocation for the
Ethernet interface (TCP/IP) in
DHCP mode:
1. OFF (fi xed IP address)
The user selects the IP address, network mask
and gateway on the device. Use this mode for
straightforward networks without DHCP servers.
2. BOOTP
Automatically integrates your device into an
existing network. BOOTP is an older protocol and
has a smaller scope of functions than DHCP.
3. DHCP
When started, the device automatically receives
the IP address, the network mask and the gateway
from the DHCP server.
Standard setting for the device is DHCP!
Communication via Ethernet interface (TCP/IP)

WARNING!
Risk of injury due to electric
voltage!
Severe bodily injuries or death can occur due
to:
• touching bare or stripped wires that are
live,
• current measurement inputs that are
dangerous to touch on the device and on
the current transformers.
De-energise your device before starting
work! Check that it is de-energised.
Earth the system. To do this, use the earth
connection points with the earthing symbol.
Also earth the secondary windings on the
current transformer and all metal parts on
the transformer that are able to be touched.

RECOMMENDATION!
For a PE/N measurement, connect the
protective earth (PE) to measurement
input V4. Do not use a green and yellow
wire for this as the conductor does not
have any protective function!
The voltage measurement inputs are designed for
measurements in low voltage networks, in which the
following rated voltages occur:
• Per IEC - 417 V phase to earth and 720 V phase
to phase in the 4-conductor system.
• Per UL - 347 V phase to earth and 600 V phase to
phase in the 4-conductor system.
• 600 V phase to phase in the 3-conductor system.
The measurement and surge voltages meet
overvoltage category 600 V CATIII.
User manual:
The device is a class A power quality analyser
that
• measures and calculates electrical variables
such as voltage, current, power, energy,
harmonics, etc. in building installations,
on distribution units, circuit breakers and
busbar trunking systems.
• measures and monitors residual currents
(RCM) and currents at the central
grounding point (CGP). The residual current
monitoring is carried out via an external
residual current transformer (30 mA rated
current) on the current measurement inputs
I5 and I6.
• displays measurement results and transmits
them via interfaces (Ethernet, Modbus,
Profi bus).
m
CAUTION!
Damage to property due to
not observing the installation
instructions
Failing to observe the installation instructions
can damage or destroy your device.
Ensure that there is adequate air circulation
in your installation environment; if the
ambient temperatures are high, ensure there
is adequate cooling if required.

NOTE!
Detailed information on the device
functions and data can be found in the
user manual.

Voltage measurement in the three-phase
four-conductor system (TN, TT networks).
Note: Earth your system! Voltage measurement in the three-phase three-
conductor system (IT network).
The device is only suitable for use in IT networks
to a limited extent, as the measured voltage
relative to the housing potential is measured and
the input impedance of the device creates residual
current against the earth. The residual current can
trigger insulation monitoring in IT networks.
Connection variants with voltage transformers
are suitable for IT networks without
restrictions!

observing the connection conditions or
impermissible overvoltages
Your device can be damaged or destroyed by a failure to
comply with the connection conditions or by exceeding the
permissible voltage range.
Before connecting the device to the supply voltage,
check:
• The ground wire connection must be connected with
the system earthing!
• The voltage and frequency must meet the
specifi cations on the rating plate! Adhere to the
threshold values as described in the user manual!
• In building installations, the supply voltage must be
protected with a UL/IEC approved circuit breaker /
a fuse!
• The circuit breaker
- must be easily accessible for the user and be
installed close to the device.
- must be labelled for the relevant device.
• Do not connect the supply voltage to the voltage
transformers.
•
Provide a fuse for the neutral conductor if the
source's neutral conductor connection is not earthed.


RECOMMENDATION!
For a PE/N measurement, connect the
protective earth (PE) to measurement
input V4. Do not use a green and yellow
wire for this as the conductor does not
have any protective function!
The voltage measurement inputs are designed for
measurements in low voltage networks, in which the
following rated voltages occur:
• Per IEC - 417 V phase to earth and 720 V phase
to phase in the 4-conductor system.
• Per UL - 347 V phase to earth and 600 V phase to
phase in the 4-conductor system.
• 600 V phase to phase in the 3-conductor system.
The measurement and surge voltages meet
overvoltage category 600 V CATIII.
User manual:
The device is a class A power quality analyser
