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.
m
Residual 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!
