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

UMG 605
Intended use
The UMG605 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 UMG605 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
UMG605 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 UMG605 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 UMG605 fulfils the test requirements for
use in industrial areas.

Operating concept
You can program the UMG605 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 UMG605.
• 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 UMG605 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”.
Use the parameter list in the
appendix to these instructions for
programming at the UMG605 and
the modbus address list on the
data carrier included in the scope of
supply for programming via a serial
interface.

Methods of measurement
The UMG605 measures continuously and
calculates all effective values over a 200 ms
interval.
The UMG605 measures the real effective va-
lue (TRMS) of the voltages and currents ap-
plied to the measurement inputs.

Three-phase 4-wire systems
The UMG605 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 UMG605 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 UMG605 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 UMG605 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.

Power supply voltage
A power supply voltage is required for
operation of the UMG605. The type and
amount of power supply voltage required is
noted on the rating plate.
Before applying the power supply voltage,
ensure that the voltage and frequency match
the information given on the rating plate!
The connection cables for the power supply
voltage must be fused with a UL listed fuse
(6A type C).
- A disconnector or circuit-breaker
must be provided for the power
supply voltage in the building
installation.
- The disconnector must be installed
near the device and must be easy
for the user to reach.
- The switch must be labelled as a
disconnecting device for this device.
- Voltages which are above the
allowable voltage range can destroy
the device.

The UMG605 can only determine
measured values if a measurement-
current voltage greater than 10 Veff
is applied to at least one voltage
measurement input.
Voltage measurement
The UMG605 is designed for the measurement
of alternating voltages in 300 V systems in
which category III overvoltages can occur.
The UMG605 can only determine measured
values if a measurement-current voltage
greater than 10 Veff is applied to at least one
voltage measurement input.
The following must be noted when selecting
the instrument leads for the voltage
measurement:
• The instrument leads required for the
voltage measurement must be suitable
for voltages up to 300 VAC to earth and
520 VAC conductor to conductor.
• Normal instrument leads must be fused by
an overcurrent protective device and routed
via disconnectors.
• Short-circuit proof instrument leads must be
routed via disconnectors only.
Overcurrent protective devices and
disconnectors must be positioned near the
device and must be easy for the user to reach.
