Protective Wire Connection
Use a ring cable lug for connecting the protective wire to the UMG508.
Supply Voltage
A supply voltage is required to operate the
UMG508. The type and level of the necessary
supply voltage is noted on the label.
Before applying the supply voltage, make sure
that the voltage and the frequency match the
details on the label!
The auxiliary voltage has to be connected via an
UL/IEC approved fuse (1A Class CC) or a circuit
breaker (1A C.Char.)

Voltage Measurement
Three-phase 4 conductor systems
The UMG508 can be used in three-phase 4 conductor systems (TN, TT network) with a grounded neutral wire. The bodies of the electrical
system are grounded.
Three-phase 3 conductor systems
The UMG508 is only suitable for use in IT networks with restrictions, because the measurement voltage is measured against the housing
potential and the input impedance of the device
causes a leakage current against ground. The
leakage current can cause isolation monitoring
in IT networks to respond.
Connection variations with a voltage transformer are suitable for IT networks without any restrictions.

UMG 508
The following has to be considered when connecting the voltage measurement:
• A suitable separator is to be provided in order
to disconnect the UMG508 from the current
and voltage.
• The separator must be placed near to the
UMG508, labelled for the user and must be
easy to reach.
• Use for over current protection and circuit
breaker an UL/IEC approved fuse 10A Class
CC.
• The overcurrent protection device must have
a nominal value calculated for the short-circuit current at the connection point.
• Measurement voltages and measurement
currents must come from the same network.
Warning!
The voltage measurement inputs on the
UMG508 are dangerous to touch!
c
Warning!
The UMG508 is not suitable for measuring DC voltages.
Warning!
Voltages that exceed the authorized
network nominal voltages must be
connected using a voltage converter.

UMG 508
Current measurement
The UMG508 is designed for connecting current
converters with secondary currents of ../1A and
../5A. Only alternating currents, and no direct
currents, can be measured.
Each current measurement input can be loaded
with 120A for 1 second.
Grounding current converters!
If a connection is provided for grounding the secondary winding, this must be
connected with ground.
Illu. Connection example, current measurement
using current converter.
Warning!
The UMG508 is not suitable for the
measurement of direct voltages.
Warning!
The current measurement inputs are
dangerous to touch.

UMG 508
Current converter connections!
The secondary connections of the current converter must be short-circuited
to these before the electricity cables
are disconnected from the UMG508!
If a test switch is available which automatically shorts the secondary current
converter lines, it is sufficient to set
them to the "test" extradata, as long as
the short-circuiters have been checked
beforehand.
Open current converters!
Extreme contact danger due to voltage
peaks can occur on current converters
that are operated open on the secondary side!
For "anti-open current converters", the
winding isolation is calculated so that
the current converters can be operated
open. However, these current converters are also dangerous to touch if they
are operated open.
cc
Current Direction
The current direction can corrected on the device or individually using the available serial interfaces for each phase.
In the case of incorrect connection, subsequent
reconnection of the current converter is not necessary.
26
UMG 508
Total current measurement
If the current is measured using two current
converters, the total transfer ratio of the current converters must be programmed in the
UMG508.
Illu. Example, current measurement using a total
current converter.
Example
The current measurement takes place using
two current converters. Both current converters have a transfer ratio of 1000/5A. The total
measurement is carried out with a 5+5/5A total
current converter.
The UMG508 must then be set as follows:
Primary current: 1000A + 1000A = 2000A
Secondary current: 5A

Illu. Example, current measurement with an additional ampere meter.
Ampere meter
If you do not want to measure the current with
the UMG508 alone, but also with an additional
ampere meter, the ampere meter must be switched in series to the UMG508.
Illu. Example, direct current measurement.
Direct measurement
Nominal currents up to 5A can also be directly
measured with the UMG508.
Under consideration that the direct measurement will be carried out for the current only in
three phase 4 wire systems with mains voltage till
• 127V/220V (300V CAT III) according UL
and three phase 3 wire systems with mains
voltage till
• 277V (300V CAT III) according UL
Due to the fact that the UMG508 does not
have integrated protection for the current
measurement, this protection must be foreseen in the installation.

Illu. UMG508 with DSUB socket for the RS485
interface.
DSUB socket
for Modbus
or Profibus.

Connection of Bus Lines
The incoming bus line is connected to clamps
1A and 1B. The bus line for the next device in
the line is connected to clamps 2A and 2B. If
there is no further device in the line, the bus line
has to be terminated with resistors (switch to
ON).
In switch extradata ON, clamps 2A and 2B are
switched off for the continuing bus line.
Illu. Profibus plug with terminating resistors.

Shields
A twisted, shielded cable is foreseen for connections using the RS485 interface.
• Ground the shields of all cables leading to the
cabinet at the cabinet entry point.
• Connect the shield extensively and with
good conductivity with a low external voltage
ground.
• Intercept the cable mechanically above
the ground clip in order to avoid damages
caused by cable movements.
• Use suitable cable insert guides, such as PG
glands, to guide the cable into the switch cabinet.
Cable type
The cables used must be suitable for an environmental temperature of at least 80°C.
Recommended cable types:
Unitronic Li2YCY(TP) 2x2x0.22 (Lapp cable)
Unitronic BUS L2/FIP 1x2x0.64 (Lapp cable)
Maximum cable length
1200m at a Baud rate of 38.4k.
Illu. Shielding arrangement at cabinet entry
point.

Terminal resistors
The cable is terminated with resistors (120Ohm
1/4W) at the beginning and end of a segment.
The UMG508 does not have any terminal resistors.
C
For the wiring of the Modbus connection, CAT cables are not suitable.
Please use the recommended cables.
