Concerning this operation manual

This operation manual is part of the product.

• Read the operation manual before using the device.

• Keep the operation manual instructions throughout

the entire service life of the product and have them

readily available for reference.

• Pass the operation manual on to each subsequent

owner or user of the product.

Inspection on receipt

The prerequisites of faultless, safe operation

of this device are proper transport and proper storage,

set-up and installation, as well as careful operation and

maintenance. If it can be assumed that risk-free operation

is no longer possible, the device must be immediately

put out of operation and secured against being put back

into operation again.

Packing and unpacking must be carried out with

customary care without the use of force and only using

suitable tools. The devices should be visually checked

for ﬂawless mechanical condition.

It can be assumed that risk-free operation is no longer

possible if the device, for example,

• has visible damage

• no longer works despite the mains power supply

being intact

• has been exposed to prolonged adverse conditions

(e.g. storage outside the permissible climate

limits without being adapted to the room climate,

condensation, etc.) or rough handling during

transportation (e.g. falling from a height, even if there

is no visible external damage, etc.)

• please check the delivered items for completeness

before you start installing the device.

CAll screw-type terminals included

in the scope of delivery are attached

to the device.

CAll supplied options and versions are

described on the delivery note.

UMG 512

Product description

Proper use

The UMG 512 is intended for the measurement

of voltage quality according to EN61000-4-30 in building

installations, on distribution units, circuit breakers

and busbar trunking systems.

Measured voltages and measured currents must derive

from the same network.

The UMG 512 is suitable for integration into ﬁxed and

weatherproof switch panels in indoor areas. Conductive

switch panels must be earthed.

The UMG 512 can be used in 2, 3 and 4-conductor

networks and in TN and TT networks.

The current measurement inputs 1–4 of the UMG 512

are connected via external ../1A or ../5A current

transformers.

Measurements in medium and high-voltage networks are

always performed via current and voltage transformers.

The measurement results can be displayed and read

out and further processed via the interfaces (Ethernet,

Modbus, Proﬁbus).

The UMG 512 can be used in industrial and domestic

settings.

By continuously monitoring the residual currents

(RCM) of an electrical system via the inputs I5 and I6,

warning pulses can be triggered if a response threshold

is exceeded. Using these, the system operator can

be alarmed before a protective equipment reacts.

The UMG 512 does not provide protection against

electric shock!

The residual current monitoring is performed via

the current measurement inputs I5 and I6 via an

external residual current transformer with a rated current

of 30 mA.

mResidual current monitoring monitors

residual currents via external current

transformers and can trigger a warning

impulse when a response threshold

is exceeded. The device is thus not an

independent protective device!
