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).
Inspection on receipt
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.

Please read these operating instructions and
all other publications which have to be used
to work with this product (in particular for
installation, operation or maintenance).
Note and follow all safety instructions as
well as any warnings. If you do not follow the
instructions, personal injuries and/or damage
to the product could be the result.
Any unauthorised change or use of this device
which extends beyond the given mechanical,
electrical or other operating limits can cause
personal injuries and/or damage to the
product.
Any such unauthorised change is “misuse”
and/or “negligence” under the product's
warranty and therefore excludes the warranty
for cover of possible resulting injuries or
damage.

Product Description
Important!
If the device is not operated according
to the instruction manual, protection
is no longer ensured and the device
can cause hazards.
Conductors made of individual wires
must be fitted with wire end ferrules.
Only pluggable screw terminals with
the same number of poles (pins) and
of the same type may be plugged
together.

Product Description
Product Description
Intended use
The UMG604 is intended to be used for the
measurement and calculation of electrical
variables such as voltage, current, power,
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 with for these, which are
not dealt with in any greater detail here.
The UMG604 fulfils the test requirements for
use in industrial areas.
