CAUTION!
Risk of injuries or
damage to the device
Failure to observe the connection conditions
for the voltage measurement inputs can cause
injuries to you or damage to the device.
Therefore, note the following:
• The voltage measurement inputs
- must not be occupied with DC voltage.
- must be provided with a suitable,
labelled fuse that is positioned close by
and a circuit breaker (alternatively:
a line safety switch).
- are dangerous to touch.
• Voltages that exceed the permissible
network rated voltages must be
connected via a voltage transformer.
• Measured voltages and currents must
derive from the same network.

NOTE!
As an alternative to the fuse and circuit
breaker, you can use a line safety switch.

Safety measures
When operating electrical devices, certain parts
of these devices are invariably subjected to
hazardous voltage. Therefore, severe bodily
injuries or damage to property can occur if they
are not handled properly:
• Before connecting connections, earth the
device at the ground wire connection if present.
• Hazardous voltages may be present in all
switching parts that are connected to the
power supply.
• Hazardous voltages may also be present
in the device even after disconnecting the
supply voltage (capacitor storage).
• Do not operate equipment with current
transformer circuits while open.
• Do not exceed the threshold values specifi ed
in the operation manual; also adhere to this
when inspecting and commissioning.
• Observe the safety and warning instructions in
the documents that belong to the device!
Qualifi ed staff
In order to prevent personal injuries and damage
to property, only qualifi ed staff with electrical
training may work on the device, with knowledge
of
• the national accident prevention regulations
• the safety engineering standards
• installing, commissioning and operating the
device.
Proper use
The device is
• intended to be installed in switching cabinets
and small installation distributors (see step 3,
"Assembly").
• not intended to be installed in vehicles! Using
the device in non-stationary equipment is
considered an extraordinary environmental
condition and is only permitted with a special
agreement.
• not intended to be installed in environments
with harmful oils, acids, gases, vapours,
dusts, radiation, etc.
The prerequisites for faultless, safe operation
of the device are proper transport and proper
storage, set-up and installation, as well as
operation and maintenance.
The device is a fast and capable network
analyser with a 500 MHz digital signal processor
(DSP) for top-hat rail installation, which:
• 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.
• displays measurement results and transmits
them via interfaces.
Device short description

in small installation distributors in accordance
with DIN 43880 on a 35 mm mounting rail
(DIN EN 60715).
• The device meets the operational conditions
in accordance with DIN IEC 60721-3-3 and
is intended for weather-protected, stationary
use.
• It can be mounted in any position.
• Forced ventilation is not required.

WARNING!
Risk of injury due
to electric voltage!
Severe bodily injuries of death can occur due to:
• Touching bare or stripped wires that are live.
• Device inputs that are dangerous to touch.
De-energise your device before starting
work! Check that it is de-energised.
The supply voltage level for the device is specifi ed
on the rating plate.
After connecting the supply voltage, an indication
is shown on the display. If no display appears,
check whether the supply voltage is within the
rated voltage range.

CAUTION!
Damage to property due
to not observing the
connection conditions or
impermissible overvoltages
Failure to observe the connection conditions
or exceeding the permissible voltage range
can damage or destroy your device.
Before connecting the device to the supply
voltage, note the following:
• The voltage and frequency must meet
the specifi cations on the rating plate!
Adhere to the threshold values as
described in the operation manual!
• When installing in a building, protect
the supply voltage with a UL-listed line
safety switches/a fuse (6 A, char. B)!
• 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.

Current transformer ratio confi guration
Current transformer ratios can be assigned to each
of the 4 current transformer inputs on the device.
The factory setting is 5 A/5 A.
In addresses 000 and 001
• program the same current transformer ratios for
all 4 phases.
• current transformer ratios that are entered
overwrite addresses 010 to 041.
In addresses 010 to 041
• program current transformer ratios individually
for each phase.
The device handles programmed values in
addresses 010 to 041 with priority, whereupon it
sets addresses 000 and 001 to 0.

See the "Parameter list excerpt of current transformer
values" table in step 16 to obtain the address for your
current transformer measurement input and enter the current
transformer value as follows:
1. Switch to programming mode -
press and hold buttons 1 and 2 for 1 second.
2. The 1st position in the address area fl ashes.
3. Use button 2 to select the 1st position in the address.
4. Press button 1 to confi rm the entry.
5. The 2nd position in the address area fl ashes.
6. Use button 2 to select the 2nd position in the address.
7. Press button 1 to confi rm the entry.
8. The 3rd position in the address area fl ashes.
9. Use button 2 to select the 3rd position in the address.
10. Press button 1 to confi rm the entry.
11. The position that is to be programmed in the content area
fl ashes.
12. Use button 2 as described above to program the current
value for the address area that you set.
Note that the unit can also be set for the primary currents.
Handle these in accordance with this programming procedure
for each current transformer ratio of your current transformer
measurement inputs.
Display example 2:
The secondary current of each current
transformer on the 4 current measurement
inputs (L1, L2, L3, L4) is set to 1 A.

The voltage measurement inputs are designed for
measurements in low voltage networks, in which
rated voltages of up to
• 277 V phase to earth and 480 V phase to phase
in the 4-conductor system or
• 480 V phase to phase in the 3-conductor system
occur.
The measurement and surge voltages meet
overvoltage category 300 V CATIII.

RECOMMENDATION!
Connect the protective earth (PE) to
measurement input V4 (L4) for a PE/N
measurement. Do not use a green and
yellow wire for this as the phase does
not have a protective function (see fi g.
