Inspection on receipt
Fault free and safe use of this device requires
appropriate transport, proper storage, erection
and assembly as well as careful operation and
maintenance. If it can be assumed that safe
operation is no longer possible, the device
must be immediately taken out of service and
secured against being accidentally started
up.
The device must be unpacked and packed
with the usual care, without the use of force
and only using suitable tools. The devices
must be visually inspected for perfect
mechanical condition. Please also note and
follow the installation instructions enclosed
with the device.
It can be assumed that safe operation is no
longer possible if the device, e.g.
• has visible damage,
• no longer works, despite intact mains power
supply,
• has been exposed to unfavourable conditions
(e.g. storage outside the permissible climatic
limits without adjustment to the ambient
climate, condensation, or similar) for a lengthy
period or was exposed to unfavourable effects
or loads during transport (e.g. fall from a large
height even if there is no visible external
damage, or similar).
Please check the scope of supply for
completeness before you start installing the
device.
All supplied options and design
versions are described on the delivery
note.
The installation and start-up instruc-
tions also describe options which do
not belong to the scope of supply.
All screw-type terminals belonging to
the scope of supply are plugged into
the device.

UMG 604
Product Description
Intended use
The UMG604 is intended to be used for the
measurement and calculation of electrical
variables such as voltage, current, energy,
work, harmonic components, etc. in building
installations, at distribution boards, circuit-
breakers and busbar trunking systems.
Measuring-circuit voltages and currents must
originate from the same system.
The UMG604 is permanently installed in
control cabinets or small distribution boards.
It can be installed in any position.
The measurement results can be displayed,
stored and read out via serial interfaces and
further processed.
The voltage measurement inputs are designed
for measurements in low-voltage systems in
which rated voltages up to 300 V conductor
to earth and surge voltages of overvoltage
category III can occur.
The current measurement inputs of the
UMG604 are connected via external ../1A or
../5A current transformers.
Mains failure detection
The mains failure detection takes place via the
voltage measurement inputs. The selection of
voltage measurement inputs can be configured
using the GridVis software.
Mains failure stored energy time
The UMG604 bridges the following mains
failures at the auxiliary voltage input:
Mains voltage Stored energy time
230V AC max 80ms
Measurement in medium and high-voltage
systems takes place with current and voltage
transformers. Special safety requirements
must be complied, which are not dealt with in
any greater detail here.
The UMG604 fulfils the test requirements for
use in industrial areas.

Operating concept
You can program the UMG604 and call up
measured values in several ways.
• Directly at the device using 2 keys and the
display. You can change the values in the
parameter list (see Appendix) and call up
the measured values from the measured
value displays.
• Via the GridVis programming software.
• In devices with an ethernet interface, via
the homepage of the UMG604.
• Via the RS485 with the modbus protocol.
You can change and call up data with the
help of the modbus address list (is filed on
the enclosed data carrier).
Operation of the UMG604 via the integrated
display and the two keys only is described in
these operating instructions.
The GridVis programming software and the
homepage have their own “online help”.
Methods of measurement
The UMG604 measures continuously and
calculates all effective values over a 200 ms
interval.
Use the parameter list in the
appendix to these instructions for
programming at the UMG604 and
the modbus address list on the
data carrier included in the scope of
supply for programming via a serial
interface.

UMG 604
Three-phase 4-wire systems
The UMG604 can be used in three-phase
4 conductor systems (TN, TT system) (50 Hz,
60 Hz) with earthed PEN conductor. The
bodies of the electrical system are earthed.
The conductor to neutral conductor voltage
may not exceed 300 V AC.
The UMG604 is only suitable for environments
in which the impulse voltage withstand
level of 4 kV (overvoltage category III) is not
exceeded.

Three-phase 3-wire systems
The UMG604 can be used in unearthed
three-phase 3 wire systems (IT system). The
conductor to conductor voltage may not
exceed 480V AC (50 Hz, 60 Hz).
The UMG604 is only suitable for environments
in which the impulse voltage withstand
level of 4 kV (overvoltage category III) is not
exceeded.
In the IT system the neutral point (star point)
of the voltage generator is not earthed. The
bodies of the electrical system are earthed.
Earthing via high-resistance impedance is
allowed.
IT systems are only allowed in certain systems
with their own transformer or generator.

Use
The UMG604 has a display, keys 1 and 2 and
the Service key to make it easier to install and
start up the UMG604 without a PC.
Important parameters such as current
transformers and device address are included
in the parameter list (see Appendix) and can
be directly programmed at the device.
A differentiation is made between operation
with the
• display mode and
• Programming mode.
Key functions
Press the key “briefly”:
• page forwards
• Digit/value +1
Press the key for “long time”:
• page backwards
• Digit/value -1
Simultaneously press both keys for around
1 second and keep them pressed:
• Switch between display mode and
programming mode.

Important!
The user can use the GridVis/Jasic to
reconfigure the function of the keys
and selection of the values to be
displayed.
Display mode
After the power supply is resumed the device
is in Display mode.
In Display mode you can use Keys 1 and 2 to
page between the measured value displays.
Press Key 2 to page between the
measured values for current, voltage,
power output, etc.
Use Key 1 to select the phase for the
measured values.
The factory default setting for the measured
value displays is shown in the “measured
value displays” in the Appendix.

Programming mode
The most important settings required for
operation of the UMG604 can be displayed
and changed in programming mode.
The parameter list in the Appendix contains
the addresses for the most important settings.
You can make further settings using the GridVis
software included in the scope of supply.
If you simultaneously press Keys 1 and 2 for
around 1 second, programming mode opens
via a password query. If a display password has
not been programmed, the first programming
menu opens directly.
Programming mode is denoted in the display
by the text “PRG”. The digits of the address
flash.
If you are in programming mode and have not
pressed a key for approximately 60 seconds or
simultaneously press Keys 1 and 2 for around
1 second, the device returns to display mode.
