• Connect the voltages higher than
the#permitted network rated voltages
using voltage transformers.

• The voltage measurement inputs
on the device are dangerous
if touched!

• Also install a disconnector for the
measured voltage as described in “6. 1
Disconnectors”.

c

CAUTION!

Malfunction due to

incorrect connection

If the device is connected incorrectly,
incorrect measured values may be returned.

Therefore, note the following:

• Measured voltages and currents must
derive from the same network.

• The device is not suitable
for measuring DC voltage.

Fig.23.1 Connection example: Voltage measurement via

short circuit-proof measurement wires

Note the following when selecting
the measurement wires:

• Use measurement wires that are suitable
for 300 V to earth and 520 V conductor
to conductor.

• Fuse the normal measurement wires using
an overcurrent protection device.

• Route normal short circuit-proof
measurement wires via a disconnector.

6. 4 Frequency measurement

The device is suitable for measurements in
networks in which the fundamental oscillation
of the voltage is in the range of 15 to 440 Hz.

In order to determine the mains frequency
automatically, a voltage L1-N of greater than
10 Veff must be applied to voltage input V1.

The mains frequency is only measured
on the measurement inputs of the baseline
measurement (V1, V2, V3).

6. 5 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
are continuously loaded with 6 A or loaded
with 100 A for 1 second.

m

WARNING!

Risk of injury due

to electric voltage

on current transformers!

On current transformers that are operated
open on the secondary side,
high voltage peaks that are dangerous to
touch can occur, which can cause severe
bodily injuries or death.

Therefore, note the following:

• Avoid operating the current
transformers open.

• Short circuit all unloaded current
transformers.

• Connect the earthing connections provided
on the current transformer to the earth.

• You must short circuit the secondary
connections on the current transformer
before interrupting the power supply.

• If a test switch, which automatically
short-circuits the secondary wires
of the current transformer is available,
it is suffi cient to set this to the "Test"
position as long as the short-circuiting
device has been checked beforehand.

• Ensure that the attached screw­type terminal is affi xed to the device
suffi ciently using the two screws.

• Safe open-circuit current transformers
are also dangerous to touch when they
are operated open.

6. 5. 1 Ammeter

If you wish to measure the current not only
with the UMG but rather with an ammeter
too, connect the ammeter to the UMG
in series.

6. 5. 2 Total current measurement

F

or a summation measurement via
two current transformers, first set their
total transformation ratio on the device.
For information on setting the current
transformer ratios, see “11. 2 Current
transformer ratio”.

Example:

The current is measured via two current
transformers. Both current transformers
have a transformation ratio of 1000 / 5 A.
The summation measurement is performed
using a 5+5 / 5 A total current transformer.

The device must then be set up as follows:

Primary current: 1000 A + 1000 A = 2000 A
Secondary current: 5 A

6. 5. 3 Direct measurement

Rated currents of up to 5 A can be measured
directly on the device. When doing so, note
that each current measurement input can be
continuously loaded with 6 A or loaded with
max. 100 A for 1 second.

The device does not have integrated
protection for current measurement.
Therefore, provide a 6 A line protection fuse
or automatic circuit breaker as protection
against overcurrent when installing.
